Building inspection Haarlem: knowledge base

Building inspection Haarlem knowledge base. Premiumkeur inspects homes in Haarlem and the rest of Kennemerland: Heemstede, Bloemendaal, Zandvoort, Velsen, Beverwijk, Heemskerk and Castricum. We are a branch of Premiumkeur B.V., an independent building surveying firm with its head office in Amsterdam (Chamber of Commerce (KvK) 81106130). The Haarlem branch is at Tempeliersstraat 63, 2012 EC Haarlem.

A standard building inspection costs € 499 including VAT for a home up to 800 m³. The inspection takes 1 to 1.5 hours on average. You will have the report within 2 working days. We work to NTA 8060, are approved by NHG (National Mortgage Guarantee) and are NEN 2767 certified. We do not work with estate agents.

This knowledge base covers what you need to know as a buyer or owner in this region: the inspection, the costs, foundations in Haarlem, damp, roofs, owners’ associations (VvE) and the purchase agreement. After that come practical cases from our own reports from Haarlem and Kennemerland. Premiumkeur has an average of 4.9 stars from 698 Google reviews and 100 Trustpilot reviews.

This page is the English version of our Dutch knowledge base (kennisbank). Reviews that clients wrote in English are on our page English reviews.

1. How a building inspection works

The inspection is a visual inspection: we look, measure and take photos, but we do not open anything up. The inspector walks through the house from roof to crawl space. This takes 1 to 1.5 hours on average.

What the inspector looks at

• The roof. The inspector goes onto it if that can be done safely and responsibly.
• The crawl space, if it is accessible: floor joists, moisture content, ventilation, pipework and the visible part of the foundation.
• Facades, cracks and tilt. In older houses we measure bed joints and floors.
• Installations: fuse box, central heating boiler, gas pipe, water, drainage, ventilation and smoke detectors.

What is not included

What we cannot see or reach is stated in the report, with the reason. An asbestos survey is not part of the inspection. If we see suspected asbestos material, we report it. Have it examined by a specialist firm before you sign.

The report

For each building element you get photos, a condition score according to NTA 8060, an explanation and a cost indication including VAT. The costs are shown in three columns: needed immediately, within five years and improvements. An inspection is a snapshot of what is visible on that day.

When to call us

Make your offer with a building inspection condition (voorbehoud) and call us straight after the verbal agreement. The condition usually runs for only a few weeks. We can often come within 1 working day. If you already have a report from another firm and you have doubts, we can carry out a second opinion (contra-expertise), from € 599.

2. Prices in Haarlem and Kennemerland

All amounts are given including VAT, as at October 2026. They are the same as the prices of Premiumkeur Amsterdam.

What repairs cost

The report gives a cost indication for each defect. For foundation repair we give a price per m², not a total amount, because the differences between properties are large. Foundation repair costs from € 2,500 per m², and from € 3,500 per m² with a cellar. The finishing work afterwards costs from € 3,000 per m². Drawings and permit cost € 10,000 on average.

3. Building and living in Haarlem and Kennemerland

The homes we inspect in this region were often built between 1880 and 1940. In our reports the main issues are tilt, damp in the crawl space, affected beam ends and leaking flat roofs on extensions.

• Many listed buildings in the old centre of Haarlem are built on shallow foundations (op staal), so without timber piles.
• In the Rozenprieel, in a bend of the Spaarne, the peat soil settles unevenly. Timber piles have also been affected there. According to NH Nieuws, in 2019 the repair of 300 to 500 homes was under way, supervised by the KCAF on behalf of the municipality (NH Nieuws, 21 October 2019).
• Both types of foundation occur in our Haarlem reports: shallow foundations (cases 12, 17 and 20) and timber piles (cases 1 and 9). In some places there are layers of clay and peat under the sand (cases 9 and 17). The ground subsidence we mention in the reports is usually small: around 0.1 to 0.2 mm a year (cases 3 and 4). A tilt can therefore be old and no longer moving; only measuring over a few years will show this.
• An extension or add-on often has a different, shallower foundation than the main house. The extension then settles separately from the house and cracks appear at the join.
• In the coastal towns of Zandvoort and IJmuiden we pay extra attention to facades, window frames and roofs that take a lot of wind and rain.

4. Foundations

Until about 1970, homes in the Netherlands were often built on timber piles (RVO). The year of construction says something about the type of foundation, but not about its condition. That only becomes clear from measurements. Our advice: for a house built before 1970, have the foundation investigated before you buy.

Signs

Leaning facades, bed joints that run out of line, cracks above windows and doors, sticking doors and sloping floors. A clear difference from the neighbours is also a sign. Cracks can also have other causes, such as shrinkage, a missing lintel or a settled extension. Only measurements show whether the foundation is the cause.

The foundation label (funderingslabel)

Since 1 April 2026, every valuation report includes a foundation label from A to E. The valuer determines the label on the basis of visible signs and online data. For class D or E the valuer advises further investigation (Ministry of BZK, 1 April 2026). The label is a risk indication, not a foundation investigation.

Types of foundation investigation

1. Foundation quick scan (phase 0): bed joint measurement and floor levelling during the inspection. Together with the inspection from € 898.
2. Phase 1: more extensive investigation above ground, € 699 to € 1,499. Archive research costs extra.
3. Phase 2: the foundation is dug out and examined up close. From € 3,000, excluding excavation.
4. Monitoring bolts: 8 to 10 bolts for € 1,179. After measuring for 2 to 3 years you know how fast the building is sinking.

A tilt is a snapshot. If a building sinks evenly by less than 1 to 2 mm a year, further investigation is usually not needed. At more than 2 mm a year, phase 1 or phase 2 follows.

Who pays for repair?

For an apartment the VvE pays, and each owner contributes in proportion. If you share a party wall with the neighbours, you need their permission and you usually pay part of the cost. The municipality of Haarlem is part of the national Fonds Duurzaam Funderingsherstel, which can help owners with financing (NH Nieuws, 2019).

More about foundation investigation can be found in the foundation investigation knowledge base.

5. Crawl space, damp, wood rot and dry rot (huiszwam)

Many homes in Haarlem from around 1900 to 1940 have a timber floor above a crawl space. With little ventilation or a high groundwater level, the beam ends in the facade get wet. That is where wood rot starts. We often see this in our reports from the region.

How we inspect the crawl space

We go in ourselves and examine the floor joists and the floor timber for wood rot, dry rot and woodworm. We measure the moisture content with calibrated moisture meters; dry wood is at around 12 per cent. If the crawl space is lower than 20 cm, we use a crawl space robot with a camera. If there is water, or suspected asbestos material, we do not go in.

Common defects

6. Roof, facade and equipment

We go onto the roof if it is safe to do so. For difficult leaks we use a cherry picker or scaffolding at extra cost.

What we often see on roofs and facades

• Flat roofs on extensions with bitumen at the end of its life, and outlets that are too small or blocked.
• Emergency repairs to roof covering and leadwork that are not durable.
• Leaks at chimneys and at flues that have been removed.
• Window frames with wood rot and sealant that has come loose.
• Balconies and roof terraces without a safe balustrade.

Equipment

7. Lifespan of building elements

These are indicative figures. How long something really lasts depends on quality, location and maintenance.

8. Apartments, VvE and long-term maintenance plan

With an apartment you buy part of the building. Ask for the minutes, the long-term maintenance plan (MJOP), the reserve fund and the annual accounts of the VvE. This is part of your duty to investigate. You request the deed of division with drawing from the Kadaster.

Banks often ask for an MJOP or the annual accounts for apartments. We can draw up an MJOP; for a small VvE (maximum 5 apartments) this costs € 899. Foundation repair to an apartment building is paid for by the VvE.

9. Purchase agreement and duty to investigate

Always make your offer subject to a building inspection. If the repair costs exceed the agreed amount, you can cancel free of charge.

10. Choosing an inspector

As a buyer you may choose your own inspector. An inspector recommended by an estate agent may have a business arrangement with that agent. So ask whether the inspector pays the estate agent a fee.

In the Netherlands anyone can call themselves a building inspector. What an inspection covers differs from firm to firm and is set out in the general terms and conditions. Read them before you sign. Investigative journalist Bram Logger wrote about this in The small print of home inspectors (Onderzoekscollectief Spit, 10 May 2023).

Questions you can ask any inspector:

• Do you measure the tilt of floors and bed joints?
• Do you go into the crawl space, or do you look from the hatch?
• Do you go onto the roof, or do you look from the ground or a ladder?
• What do your general terms and conditions say about the foundation, roof and crawl space?
• Does the estate agent get a fee if they refer me to you?

Premiumkeur does not accept instructions via estate agents and does not pay for referrals.

Free roof inspections and free leak detection

In Haarlem and Kennemerland, too, roofers and plumbing companies regularly offer a free roof inspection or free leak detection. Free usually means you do not pay separately for the inspection; the cost is earned back through the repair work that follows. The person who establishes the cause then also earns from the solution. Many tradespeople are honest, but the advice is harder for you to check, and a quotation can include more work than is needed.

So always ask which defect was found and how, and which part of the quotation is really needed. If in doubt, or if a large amount is involved, an independent investigation by a party that does not carry out repairs helps. Be extra careful with doorstep selling, time pressure and cash payment. According to the Dutch government (in Dutch), you generally have 14 days to cancel an agreement of more than € 50 made at your door, and on the consumer programme Kassa (2015, in Dutch) the trade association for roofers advised never to accept a job from a company that only wants cash.

11. Specialist investigations and baseline survey

• Dispute with a contractor: we assess the work and write an expert report, from € 599.
• Baseline survey: records the condition of your property before building work starts, at your home or your neighbours’. € 499.
• Handover inspection for a new build or after a renovation: € 499.
• Listed buildings: we inspect many listed buildings in the centre of Haarlem.

12. Case studies from Haarlem

These cases come from our own reports, 2022 up to and including 2026. Addresses and names have been left out. Amounts are the estimates from the report, at the price level of that year.

Case 1: Low foundation risk despite cracks at the bay window, Haarlem

Situation: Occupied terraced house from 1932 with 2 storeys, with an owners’ association (VvE), in a block of 8 upstairs and downstairs flats on a timber pile foundation. Reason in October 2026: the client asked for a foundation quick scan (quickscan fundering) of the foundation risk.

Findings:

• The bed joint measurement on the front facade gives a settlement difference of 9 mm over 4000 mm, a rotation of 1:444 (category ‘Nil’).
• The plumb measurement gives a difference of 10 mm over 3000 mm, a rotation of 1:300 (category ‘Small’).
• On the first floor the largest deviation is +15 mm at the stairwell; this is attributed to the floor construction.
• The cracks above the bay window are attributed to the steel lintel combined with a non-load-bearing plastic frame.
• Over the past 10 years the groundwater repeatedly dropped below -0.8 m NAP (Amsterdam Ordnance Datum), the level of the pile heads.

Advice: No immediate foundation measures or further foundation investigation needed; do stay alert to cracks or tilt. If in doubt, repeat the foundation quick scan after about three years at the same measuring points.

What this shows: Cracks in a facade can come from a lintel or frame construction rather than from the foundation. Foundation timber drying out in the past is a point of attention, but does not prove deterioration.

Case 2: Wood rot in the crawl space due to damp and an old leak, Haarlem

Situation: Occupied terraced house from 1927 with 3 storeys, no VvE. Reason in October 2026: the client had the crawl space inspected for the timber floor, damp and ventilation. The compartment under the hall could not be reached.

Findings:

• Under the living room both ends of the supporting beam (onderslag) and most of the beam ends on the left side are severely affected by damp and wood rot.
• The relative humidity was about 86% under the living room, 85% under the kitchen and 82% under the extension.
• Under the kitchen the beam ends and floor boarding are severely affected; the pattern fits a long-standing leak from the kitchen drain.
• Under the extension there is no severe wood rot, but there is about 20% moisture content in the beam ends and corroded beam shoes.
• Signs of rising damp were found in the load-bearing walls.

Advice: Repair or replace the affected supporting beam, beam ends and floor boarding, improve the ventilation per compartment and deal with the rising damp. Have both local repair and full floor replacement priced.

What this shows: In a damp crawl space, wood rot is rarely limited to a single beam. A leak that seems to have been repaired can have done major unseen damage to the floor.

Case 3: Moderate tilt in a terraced house from 1906, Haarlem

Situation: Occupied terraced house from 1906 with 2 storeys and a loft, part of a structural unit of at least 3 homes, no VvE. Reason in September 2026: the client asked for an independent foundation investigation quick scan.

Findings:

• Bed joint measurement, front facade: 24 mm difference over 4500 mm, rotation 1:187, category moderate, damage type architectural.
• Floor levelling survey at the front facade: 24 mm over 3000 mm, rotation 1:125, likewise moderate and architectural.
• Ground subsidence in the area averages around 0.1 mm/year; negligible.
• Inside there are mainly hairline cracks and very small cracks; the crack in the rear facade is caused by a missing lintel above the frame.

Advice: Install monitoring bolts and monitor for 2 to 3 years. With uniform settlement of at most 1 to 2 mm per year, no further investigation is needed; with more than 2 mm per year, a full foundation investigation follows (phase 1 and possibly phase 2).

What this shows: Moderate tilt is a snapshot and does not say how fast the building is sinking. Only monitoring over several years gives certainty about the rate of settlement.

Case 4: High foundation risk despite minor ground subsidence, Haarlem

Situation: Occupied terraced house, presumably from 1610, 2 storeys, with a VvE. Reason in September 2026: the client had an independent building inspection carried out before purchase. The report calls the building a listed monument.

Findings:

• The building visibly leans forward, with diagonal and vertical cracks that return after repair, and frames that are out of true.
• Bed joint measurement at the reveal blocks of the later part of the facade: about 7 mm height difference; this says nothing about the original building.
• Ground subsidence is about 0.2 mm per year (end of 2017 to end of 2022); the foundation risk has nevertheless been assessed as high.
• The roof construction shows visible sagging.
• Immediate costs: total € 2,950 (2026 price level), including € 850 for the roof window connection and € 1,200 for the staircase balustrade; repair of the frames: costs to be determined.

Advice: A foundation investigation phase 2 before signing the purchase agreement. Without that investigation, install monitoring bolts and monitor annually (usually at least five years of data). A structural engineer can assess the roof deflection.

What this shows: Minor ground subsidence does not rule out a high foundation risk in a very old building.

Case 5: Affected beam ends in the crawl space of a house from 1932, Haarlem

Situation: Semi-detached house from 1932, occupied, no VvE. In September 2026 the client had a crawl space inspection carried out.

Findings:

• Raised moisture values were measured in the timber floor construction, mainly at the right side facade and under the stair cupboard.
• Signs of rising damp were seen next to the front door, in the meter cupboard and at the stair cupboard.
• Several beam ends at the bearing points in or against damp brickwork are so affected that a pointed tool goes into the wood without great force.
• There are indications of woodworm. Insulation chips on the floor limit the assessment.

Advice: The report describes three options: keep and repair the joist floor, replace the floor with an insulated concrete or combination floor, or at a minimum have the woodworm investigated and treated with periodic checks. Full replacement is preferred structurally, at higher cost.

What this shows: Damp from brickwork mainly attacks the beam ends at the bearing points. Woodworm treatment alone is not structural repair and does not solve the cause of the damp.

Case 6: Damp in walls and floor with a structural cause, Haarlem

Situation: Occupied terraced house from 1920, no VvE. Reason in September 2026: the client asked for a visual structural inspection for defects and damp problems, with moisture measurements.

Findings:

• At the bottom of the front, rear and side facades, raised moisture values were measured that decrease with height, a pattern that fits rising damp.
• The pointing of the outer facades is locally missing and heavily sanded away; on the top floor, damp is visible on the inside of the rear facade.
• In the crawl space, wood moisture values of locally more than 39% were measured, with mould and fungus-like deterioration.
• At the rear the timber floor clearly sags; that part of the crawl space was not accessible.

Advice: Tackle the damp at the source: have the horizontal damp-proof course investigated and repaired, renew the pointing and make the crawl space structurally drier. In the short term, open up the closed-off part of the crawl space and have the joist layer assessed.

What this shows: Damp in a home does not always come from heating or ventilating; structural causes can also produce it. Removing mould or painting over walls does not remove the cause.

Case 7: Leaking flat roofs and doubts about fire resistance, Haarlem

Situation: Occupied terraced house from before 1906 with 3 storeys, no VvE, rendered facades. Reason in September 2026: a building inspection for purchase. The crawl space had no access.

Findings:

• On all 3 flat roofs the watertight connections to the facades are missing and the substructure feels insufficiently load-bearing; repair of the connections € 2,000 (2026 price level).
• According to the occupant, party walls and floor separations are finished with a single layer of plasterboard of about 9 mm, so 30 minutes of fire resistance cannot be demonstrated; estimated € 10,000 (2026 price level).
• An active leak was found in the meter cupboard, possibly via an opening in the facade near the solar panel cabling.
• The ground floor has no radiators (€ 3,500, 2026 price level); the total of immediate costs is € 22,025 (2026 price level).

Advice: Before signing the purchase agreement, have destructive investigation carried out on the flat roofs. Adapt the separations for fire resistance using a demonstrable system and fix the leak urgently.

What this shows: A roof covering in reasonable condition can still leak if the connections are not right. Repair costs in an inspection only cover what is visible; hidden wood rot can raise the amount considerably.

Case 8: Unskilled roof repair and an unsafe stair enclosure in a flat from 1906, Haarlem

Situation: Occupied flat from 1906 with 2 storeys, above a shop, with a VvE. In August 2026 the client had a building inspection carried out.

Findings:

• The new roof covering on the flat roof has presumably been laid over the old one; near the skylight it is coming loose and blisters are visible.
• The joints of the zinc cover strips are finished with aluminium tape instead of being soldered (€ 800, 2026 price level).
• The zinc gutter at the rear has been taped over with bituminous roofing; renewing it costs € 1,500 (2026 price level).
• The stair enclosures mostly consist of tensioned ropes with openings that are too large (€ 3,500, 2026 price level).
• Suspected asbestos material was seen on the roof; the immediate costs total € 13,125 (2026 price level).

Advice: Have a roofer investigate the roof covering and the underlying roof construction before signing the purchase agreement. Replace the stair enclosures with a rigid balustrade.

What this shows: A recently renewed roof can still have defects if the new layer was laid over the old one. Tape and bitumen on zinc work are temporary fixes, not lasting repair.

Case 9: Cracks in the facades with minimal tilt, Haarlem

Situation: Occupied flat from 1895, no VvE. In May 2026 the client had a foundation risk investigation phase 0 carried out.

Findings:

• Cracks were seen in both the front and the rear facade.
• According to the foundation map, the home presumably stands on timber piles; at a depth of about 1.2 to 3 metres there is a layer of peat and clay between sand layers.
• The groundwater level fluctuates between about 0.4 metres above and 0.4 metres below NAP.
• The bed joint measurement gives a difference of about 1 mm in the front facade and 13 mm in the rear facade; the plumb measurement about 3 mm per metre, both damage category ‘nil’.

Advice: Further foundation investigation is not directly needed at this time; the investigation has been placed in risk class C. Anyone who wants more certainty about the timber piles can have a foundation investigation phase 2 carried out.

What this shows: Cracks in the facade do not have to point to a foundation problem if the measurements show hardly any tilt. An above-ground investigation does however give only an indication, not certainty about the piles.

Case 10: Severe subsidence and affected floor joists in a flat from 1900, Haarlem

Situation: Occupied flat from 1900 with a cellar and crawl space; the report assigns various items to the VvE. In March 2026 the client had a building inspection with foundation risk investigation phase 0 carried out.

Findings:

• The bed joint measurement gives a difference of 13 mm (front facade) and 17 mm (rear facade); the middle is lowest (24 and 33 mm).
• The floor levelling survey measures up to 111 mm of subsidence towards the front and 50 mm towards the rear: damage category ‘structural, very large’, with cracks down into the cellar shell.
• In the crawl space, joists are affected by brown rot and damp, without facade ventilation; renewing the joist floor costs € 25,000 (2026 price level).
• Renewing the electrical installation costs € 8,500 (2026 price level).
• The immediate costs total € 63,850 (2026 price level).

Advice: Allow for foundation repair. More certainty about active settlement comes from monitoring bolts over about five years or a phase 2 investigation. In addition, renew the joist floor and ventilate the crawl space.

What this shows: Sagging window sills and cracks in the middle of a building fit measurements that show the lowest point there. Whether the settlement continues only becomes clear from years of measuring.

Case 11: Roof terrace without a balustrade at a flat from 1998, Haarlem

Situation: Unoccupied flat from 1998 with 3 storeys. In February 2026 the client had a building inspection carried out.

Findings:

• A balustrade is missing around the roof terrace; installing one is estimated at € 6,000 (2026 price level).
• The roof covering on the terrace has been laid over the old one and one part is in poor condition (€ 850 immediate and € 650 improvement, 2026 price level).
• At the sliding door the upstand height is very limited, with a risk of water ingress in heavy rain.
• The balcony has insufficient fall towards the rainwater outlet, so water remains standing (€ 1,500, 2026 price level).
• The connection between the timber weatherboarding and brick slips is open.

Advice: Install a balustrade as soon as possible and check whether a permit was granted for the roof terrace and whether the construction has been calculated for it. Adjust the fall of the balcony or add an extra outlet.

What this shows: A roof terrace without a balustrade is an immediate safety risk. Whether a roof may be used as a terrace depends on a permit and a structural calculation.

Case 12: Uneven subsidence around a cellar, Haarlem

Situation: Occupied ground floor with a shopfront in a building from 1885, with a VvE. Reason in December 2025: a building inspection with an additional foundation risk investigation phase 0.

Findings:

• According to the bed joint measurement, the main building has subsided severely forwards and to the left, the extension on the contrary backwards; the largest differences fall in the category ‘structural large’.
• In the side facade there is a very extensive, repaired crack down to below ground level; the rear facade bulges.
• The cellar is not watertight and the joists in it are completely affected by wood rot: € 3,500 immediate and € 20,000 improvement (2025 price level).

Advice: Further structural and possibly destructive investigation of the cracks and the lintel above the shopfront, before the purchase agreement. In addition, a foundation investigation phase 2 or monitoring bolts with about five years of measurements.

What this shows: If the main building and the extension subside in opposite directions, that points to a problem in the subsoil. For a building on a shallow foundation (op staal), long-term measuring in particular gives a reliable picture.

Case 13: Tilt of 1 in 104 on load-bearing sandy soil, Haarlem

Situation: Flat from 1880 with two storeys. In October 2025 the client had a building inspection with foundation risk investigation phase 0 carried out for an intended purchase.

Findings:

• At the front, the left side lies about 29 mm lower than the right side over about 4.5 m, a rotation of about 1 in 155.
• At the rear, on the top floor, the settlement is about 36 mm over about 3.75 m, about 1 in 104. The floor levelling survey confirms this; both fall under architectural moderate.
• The boring sample profiles show mainly firm, load-bearing sand layers.
• There are cracks in the brickwork in several places that appear mainly cosmetic. The foundation risk has been assessed as moderate.

Advice: Have monitoring bolts installed and measured annually for at least five years. With a foundation on piles, a second phase of foundation investigation is possible.

What this shows: Even on load-bearing sandy soil, a building can be noticeably out of level. According to the report, at 1 in 104 structural safety is not directly at stake, but monitoring is necessary.

Case 14: Out-of-plumb chimney and foundation signals, Haarlem

Situation: Occupied terraced house from 1895 with 2 storeys, no VvE. Reason in October 2025: a building inspection without additional foundation investigation.

Findings:

• The chimney on the extension is visibly out of plumb and in danger of falling over; removing and rebuilding it costs € 6,500 (2025 price level).
• During the inspection, tilt, cracks in the brickwork and badly closing windows were seen, in a foundation risk area.
• At the front door the moisture measurement exceeds the limit value, which points to rising damp.
• The roof window has rusted through completely (€ 2,250) and the frames of the extension have wood rot at the bottom rails (€ 4,000) (2025 price level).
• The immediate costs total € 25,950, with € 7,750 longer term and € 20,000 of improvement (2025 price level).

Advice: Have the chimney removed and rebuilt immediately. Before signing the purchase agreement, have an additional foundation investigation carried out and have the cause of the rising damp investigated.

What this shows: Even with an ordinary inspection, tilt, cracks and sticking windows can be a reason to have the foundation investigated further.

Case 15: Wood rot in fascia boards and a roof without membrane, Haarlem

Situation: Unoccupied end-of-terrace house from 1974 with 3 storeys, no VvE. Reason in October 2025: a building inspection without foundation investigation. The client wanted to replace the frames, bathroom, toilet and kitchen.

Findings:

• The fascia boards have wood rot in several places; full replacement costs € 2,750 (2025 price level).
• Under the concrete roof tiles there is no vapour-permeable membrane and the roof boarding is chipboard; € 8,000 longer term has been included for the tiles (2025 price level).
• On the inside of the loft floor, signs of leaking were seen near the chimney; rain caps are presumably missing.
• The central heating boiler from 2010 is nearing the end of its life (€ 2,000 longer term) and the fuse box needs to be replaced (€ 1,200) (2025 price level).
• In the crawl space, condensation was seen on pipes and walls; mechanical ventilation with a moisture sensor costs € 1,750 (2025 price level).

Advice: Replace the fascia boards, fit rain caps on the chimney, have the roof tiles cleaned, ventilate the crawl space better and have the fuse box replaced.

What this shows: A home from the 1970s can be in reasonable condition and still have a few clear cost items, especially for the roof, fascia boards and installations.

Case 16: Damp crawl space after an extension, Haarlem

Situation: Occupied terraced house from 1930, no VvE. Reason in October 2025: the client asked for an independent inspection of the crawl space.

Findings:

• Dry timber joist floors normally have a moisture content below 12%; in the compartment by the hall up to about 19% was measured.
• In the living room compartment the moisture content rises to about 30%, and traces of active woodworm were also found there.
• Because of the extension at the rear, the original ventilation openings of the crawl space have been lost.
• Yellow mould is growing on the floor and there is open wiring that has not been properly finished.

Advice: Install mechanical ventilation through a diagonally drilled hole, with a ventilation box with moisture sensor and one suction hose per compartment. Have the woodworm treated and the wiring finished safely.

What this shows: An extension can unnoticeably close off the ventilation of the crawl space, resulting in damp and wood deterioration under the floor.

Case 17: Subsidence of an extension next to a more stable main building, Haarlem

Situation: Commercial building from 1881 with three storeys, in use as a home, no VvE. In July 2025 the client had a building inspection with foundation risk investigation phase 0 carried out.

Findings:

• The bed joint measurement gives a maximum subsidence of 17 mm at the main building, a rotation of 1 in 647. Those height differences stay within the permissible margins.
• The extension at the back has subsided 32 mm, a rotation of about 1 in 156. In the extension there are vertical cracks that widen from bottom to top.
• Under 80 cm to 1.70 m of sand lie layers of clay and peat.
• The foundation scores reasonable (main building) and moderate (extension).

Advice: Install monitoring bolts in the facades and have them measured annually for at least five years. A foundation investigation phase 2 may follow; with a shallow foundation (op staal), monitoring is the only way. Request the building drawings, proof of the foundation method of the extension and the environmental permit.

What this shows: The main building and the extension of the same property can behave differently, here 1 in 647 against 1 in 156. An extension must therefore be assessed separately.

Case 18: Shrinkage cracks and a central heating boiler at the end of its life in a house from 2008, Haarlem

Situation: Terraced house from 2008, three storeys, roof under VvE management. In May 2025 the client had a building inspection carried out, without foundation risk investigation.

Findings:

• In various places there are shrinkage and settlement cracks, mainly at corner joints; repair € 225 (2025 price level).
• The central heating boiler from 2008 is under-pressurised and, according to the sticker, was last serviced in 2020: € 350 immediate and € 2,500 longer term for replacement (2025 price level).
• The bituminous roof covering is about 17 years old, with a lifespan of 20 to 25 years.
• Exterior painting, mainly at the rear: € 3,500 (2025 price level). There is open wiring in the fuse box.

Advice: Have the central heating boiler serviced, check the flue gas discharge and have open wiring connected by an electrician. Request the VvE minutes and the long-term maintenance plan (MJOP).

What this shows: In a home of about 17 years old, the costs lie mainly in installations and painting. Cracks at corner joints are shrinkage and settlement here, repair by a painter.

Case 19: Roof inspection after roof work on a mansard roof, Haarlem

Situation: Detached house from 1900 with two storeys, no VvE. In August 2024 the client had an independent roof inspection carried out of the tiled roof with mansard roof, on which work had been carried out.

Findings:

• In many places cement is missing under the ridge tiles, so tiles stand up.
• Around the roof windows and in the loft many signs of leaking are visible.
• The roof tiles at the gutter should have run down at least 5 cm lower.
• The insulating roof membrane stops about 30 cm short of the ridge on both sides, is not taped and deviates from what was quoted.
• The tiles are fixed with screws instead of tile hooks.

Advice: The report concludes that the roof work does not meet good workmanship and that fixing, connections, membrane and gutters must be repaired.

What this shows: A roof can look finished from the outside while details such as ridge tiles, membrane connections and penetrations are not watertight.

Case 20: Almost 8 cm of subsidence and a leaking cellar, Haarlem

Situation: Occupied terraced house from 1910 with 4 storeys, no VvE. Reason in July 2024: a building inspection with a first phase above-ground foundation investigation.

Findings:

• The floor levelling survey on the ground floor shows that the house has subsided almost 8 cm towards the front; on another floor, a height difference of more than 59 mm was measured.
• The bed joint measurement of the front facade gives only 7 mm difference between left and right.
• According to the report, the cellar is ‘as leaky as a basket’; only a new concrete cellar makes it watertight, estimated at € 50,000 (2024 price level).
• Stacks of bricks have been placed under floor joists in the crawl space, and rising damp and suspected asbestos material were found.
• The immediate costs total € 61,550 (2024 price level).

Advice: Install monitoring bolts to follow the shallow foundation (op staal). Have the crawl space emptied and investigated, have the suspected asbestos material tested before the purchase agreement and allow for hidden defects from DIY work.

What this shows: A front facade that is almost level does not say everything: here the subsidence was in the lengthwise direction, from front to back.

Case 21: Defects after a renovation with a concrete floor and underfloor heating, Haarlem

Situation: Terraced house from 1906 with three storeys, no VvE. In May 2024 the client had an independent expert investigation carried out, because various structural defects became visible after the purchase.

Findings:

• The timber walls of the water meter pit are full of dry rot (huiszwam) (repair € 1,100, 2024 price level).
• The old timber floor has been replaced by a concrete floor with underfloor heating; as a result, rising and penetrating damp is suspected in the shared walls.
• Both bathrooms are not watertight and not earthed (€ 3,500 each, 2024 price level).
• The underfloor heating pipe does not lie on top of the insulation (€ 8,000, rough estimate, 2024 price level). Several doors have more than 3 cm of space underneath.
• Total € 35,000 (2024 price level).

Advice: Further destructive investigation of the damp, the underfloor heating, the sewer and the construction behind the toilets. Do not use the bathrooms until the defects have been repaired.

What this shows: A concrete floor with underfloor heating in an old house can shift damp problems elsewhere. Many defects only become visible during repair.

Case 22: Structural defects and wood rot before a renovation, Haarlem

Situation: End-of-terrace house from 1890 with 3 storeys, unoccupied, no VvE. Reason in October 2023: the client asked for an independent investigation of the construction, with a complete renovation in prospect. Some measurements were also taken.

Findings:

• In a sample of the original floor joists in the front part of the house, wood rot was found, due to leaking and moisture penetration from the roof and facade.
• Not all floor joists are level; the concrete floor on the ground floor has subsided according to the levelling survey.
• The steel construction in the rear facade has limited tilt and the rear facade does not appear to be anchored to the roof construction.
• The roof construction is not structurally sound; the wall plate on the left has been placed inwards.

Advice: A structural engineer should assess and calculate the floor joists (especially in the rear part of the house), the rear facade and the roof construction. Wood rot repair, inspection of all beam ends and of the anchors from scaffolding, and renewal of the foundation during the renovation.

What this shows: In an old building with earlier alterations, tilt can be linked to structural defects. With a planned renovation, a structural assessment is needed first.

Case 23: Subsidence of 50 mm without cracks in the facade, Haarlem

Situation: Occupied end-of-terrace house from 1910 with 3 storeys, no VvE. Reason in March 2022: an independent above-ground foundation investigation because of cracks at the right front facade, recurring cracks in the kitchen ceiling, loose bathroom tiles and cracks in interior walls.

Findings:

• The bed joint measurement shows that the right side of the front facade lies 50 mm lower than the left side.
• No severe cracks or subsidence were seen in the front and side facades.
• The cracks in the interior plasterwork are attributed to age and shrinkage, unrelated to the foundation.
• The facade has green efflorescence and the plasterwork is locally missing; the kitchen ceiling is sagging.

Advice: Install monitoring bolts to follow the foundation for longer; a second phase of foundation investigation only if absolute certainty is wanted. For the kitchen ceiling, structural drawings and additional investigation are needed, and along the facades a gravel strip 50 cm wide and 60 cm deep.

What this shows: Subsidence of 50 mm without cracks in the facade need not be a foundation problem. Cracks in interior walls and ceilings can also come from age, shrinkage or construction in an old house.

13. Case studies from Kennemerland

We also carry out many inspections outside Haarlem: in Heemstede, Bloemendaal, Zandvoort, Velsen, Beverwijk, Heemskerk and Castricum.

Case 24: Worn flat roofs with leaks throughout the building, Beverwijk

Situation: Occupied building from 1967 with a taller and a lower section, a shop unit, a warehouse and two let apartments, no owners’ association (VvE). Reason for the job in September 2026: an independent building inspection.

Findings:

• The roof covering of the lower section is crazed and torn across its whole surface; replacing it costs € 99,000 (2026 price level).
• The ground-floor ceiling shows signs of leaks in many scattered places.
• The fascia boards of the taller and lower sections have to be replaced because of wood rot (€ 9,000 and € 15,000, 2026 price level).
• The foundation risk is low (class A): no structural cracks and about 0.1 mm ground subsidence per year.
• The immediate repair costs come to € 182,125 in total, plus € 3,500 for improvements (2026 price level).

Advice: A full roof renovation in the short term, including fascia boards, lead work, roof penetrations and rooflights. In addition, replace the fuse box and repair the water meter pit.

What this shows: Scattered signs of leaks across a large ceiling point to a roof that is worn out as a whole; repairing it locally does not solve that.

Case 25: Rising damp above an inaccessible crawl space, Castricum

Situation: Unoccupied end-of-terrace house from 1938 with 3 storeys, a cellar and a timber joist floor, no VvE. Reason for the job in June 2026: a pre-purchase inspection.

Findings:

• At the right-hand inner façade the damp readings are above the limit value: rising damp, estimated at € 3,500 (2026 price level).
• The crawl space could not be inspected because of its low height and the insulation chips; around the access hatch about 15% moisture was measured in the timber.
• The balcony balustrade has subsided and cannot be repaired; replacing it costs € 2,500 (2026 price level).
• The immediate repair costs are € 17,325, plus € 3,500 in the longer term for renovating the chimney (2026 price level).

Advice: Have a damp specialist investigate the cause of the rising damp. Remove the insulation chips and have destructive testing of the timber floor carried out before signing the purchase agreement.

What this shows: A single reading at the hatch says little about a crawl space that cannot be entered, especially next to a façade with rising damp.

Case 26: Timber joist floor too damp above a dry crawl space, Santpoort-Noord

Situation: Occupied terraced house from 1926 with 2 storeys, a timber joist floor and a shed, no VvE. Reason for the job in June 2026: an independent building inspection.

Findings:

• More than 18% moisture was measured in the timber joist floor, whereas about 15% counts as dry; the crawl space itself was dry.
• Several ventilation openings are partly or fully blocked; clearing them and adding extra ventilation costs € 500 (2026 price level).
• The exterior paintwork is poor; new paintwork costs € 4,000 (2026 price level).
• Fabric-sheathed wiring was seen in the living room, and in the bathroom the socket had no earthing.
• The immediate repair costs are € 14,075, plus € 2,000 in the longer term for replacing the central heating boiler (2026 price level).

Advice: Clear the ventilation openings and add extra ducts where needed. Have a certified electrician check the wiring and earthing.

What this shows: A crawl space that looks dry can still have a timber floor that is too damp; a moisture reading in the timber shows this.

Case 27: Wet joist floor and breached walls after retrofit insulation, Velsen-Noord

Situation: Occupied end-of-terrace house from 1927 with 3 storeys and a timber joist floor, no VvE. Reason for the job in May 2026: an independent building inspection, without a foundation investigation.

Findings:

• More than 26% moisture was measured in the timber joist floor, where below 12% counts as dry; crawl space repair is estimated at € 15,000 (2026 price level).
• Because of the retrofit insulation, the ventilation openings of the crawl space no longer work and insulation material is flowing in.
• Structural walls in the crawl space have been breached without proper support; a supporting beam (onderslag) rests on timber instead of on brick piers.
• The immediate repair costs are € 33,525, plus € 15,000 for improvements (2026 price level).

Advice: Have a contractor and a structural engineer repair the structure, add extra ventilation ducts and request quotes before signing the purchase agreement.

What this shows: Retrofit insulation can block the ventilation of a crawl space, resulting in a wet timber floor.

Case 28: Subsided balcony slab above a bay window, Bennebroek

Situation: Occupied terraced house from 1960 with 3 storeys, no VvE. Reason for the job in May 2026: the client asked us to look at cracks around the bay window, after which a quick scan was carried out. Only the exterior was investigated.

Findings:

• The balcony slab above the bay window is 30 mm out of level from rear left to front right, and 14 mm along the left-hand side.
• At the rear balcony and at the neighbours’, the outer edge sits 14 to 29 mm higher than the wall side; the bay window balcony may therefore have subsided by up to 60 mm, as an indication.
• The bay window shows 6 mm over at least 2000 mm (1:333, negligible) and locally 5 mm over about 1000 mm (1:200, moderate).
• The side façade shows 15 mm over at least 7000 mm (1:466); the front, side and rear façades all fall in the category ‘negligible’.

Advice: Have the brickwork opened up and have a structural engineer determine the cause, the structural safety and the solution. Monitoring bolts can be considered to follow the settlement behaviour.

What this shows: Cracks around a bay window or balcony can point to a local structural defect even when the façades are barely out of level.

Case 29: Cracks without a foundation problem and damp near the utility room, Zandvoort

Situation: Occupied detached house from 1905 with 2 storeys, no VvE. In April 2026 the client had a building inspection carried out with a foundation quick scan (phase 0).

Findings:

• Cracks were seen in several places, including on the inside of the front façade. The bed joint measurement and floor levelling fall within the acceptable margins; the foundation risk has been assessed as fair.
• At the central heating boiler in the utility room the moisture values exceed the limit values by a wide margin, even though the façades were reportedly treated against damp about a year earlier.
• About 10% moisture was measured in the timber joist floor (limit value 12%).
• The immediate costs are € 22,250 (2026 price level), of which € 5,500 for exterior paintwork and € 5,500 for wall copings.

Advice: Have a leak detection specialist investigate the cause of the penetrating damp before signing the purchase agreement. Have the electrical installation checked, because a number of wall sockets are not earthed. A foundation investigation phase 2 is optional.

What this shows: Cracks in a façade do not automatically point to a foundation problem: measurements can show that the settlement stays within the margins. Moisture values after a façade treatment do remain a point for further investigation.

Case 30: Uneven settlement at a 1916 apartment, Zandvoort

Situation: Occupied apartment from 1916. Reason for the job in February 2026: a building inspection with an additional foundation risk investigation.

Findings:

• The bed joint measurement of the front façade shows that the left-hand side sits 33 mm lower than the right-hand side over 616 cm, a rotation of about 1:186 (architecturally moderate).
• The floor slopes strongly to the left and to the front, but in the bedroom and toilet it slopes to the right instead; the floor levelling has been assessed as very poor.
• Multiple cracking was seen in the front façade on the ground floor and the top floor.
• An active leak was measured at the meter cupboard and rising damp at the party wall on the front façade.
• The costs are estimated at € 5,400 immediate and € 1,200 in the longer term for replacing the gutters (2026 price level).

Advice: On purchase, have monitoring bolts fitted and the settlement measured annually for at least five years; a second phase of foundation investigation if more certainty is wanted.

What this shows: Uneven settlement, where parts of a building slope in different directions, weighs more heavily than an even tilt.

Case 31: Damp beam ends and subsidence at a 1928 terraced house, IJmuiden

Situation: Occupied terraced house from 1928 with a roof extension from 2006, no VvE. Reason for the job in October 2025: a building inspection with an additional foundation risk investigation phase 0.

Findings:

• At the access hatch a floor joist in the middle gave about 18% moisture and a built-in beam end more than 38%; a dry timber beam is below 12%.
• Rising damp was also measured in the structural walls.
• The building has subsided towards the front and to the right. The floor levelling on the ground floor falls in ‘structurally large’, but the foundation risk has been classed as ‘architecturally moderate’, because the timber floor itself may be deformed.
• The immediate costs are estimated at € 16,050, of which € 6,500 for the rear façade and € 1,750 for the crawl space (2025 price level).

Advice: Have destructive testing of the timber floor carried out before signing the purchase agreement, because repair can run to tens of thousands of euros. Fit monitoring bolts to follow the foundation.

What this shows: A large height difference in a timber ground floor does not have to come from the foundation alone; damp beam ends can deform the floor itself.

Case 32: Emergency roof repairs and a leak at a removed chimney flue, Heemskerk

Situation: Occupied end-of-terrace house from 1958 with 3 storeys, no VvE. Reason for the job in August 2025: a building inspection without an additional foundation investigation. The crawl space had no access hatch and was not inspected.

Findings:

• The chimney flue has been removed on the outside; inside, the moisture reading gave a maximum value, which points to an active leak (€ 500 for leak detection).
• Roof tiles do not fit properly in several places and have been sealed provisionally with lead strip and repair mortar (€ 2,000).
• There is no breathable membrane on the roof boarding, and at the roof windows the junction has also been closed with repair mortar (€ 350).
• Open wiring is visible in the fuse box and a smoke alarm turned out to have no battery.
• The total immediate costs are estimated at € 5,705 (2025 price level).

Advice: Have a leak detection survey carried out before signing the purchase agreement, and have the roof checked and repaired by a roofer. Have the electrics checked by a certified electrician.

What this shows: Provisional repairs with mortar or lead strip keep a roof closed for the time being, but often point to earlier leaks. A removed chimney flue can still let damp through on the inside.

Case 33: Cracks and damp at an extension, Heemstede

Situation: Terraced house from 1929 with two storeys, no VvE. In March 2025 the client had the building defects recorded visually.

Findings:

• At the junction of the extension with ground level, the cavity, insulation and damp-proof barrier are missing, with mould and damage to the parquet and skirting boards (€ 3,500 for the rear façade, € 7,000 including the side façade, 2024 price level).
• At the junction with the existing house there are cracks in the wall and ceiling.
• The existing structure has a shallow foundation (op staal); the ground subsidence in the area varies from 1 to 4 mm per year. Settlement greater than 2 mm per year indicates an increased risk.
• Total immediate € 13,250 and in the longer term € 5,250 (2024 price level).

Advice: First have the plasterwork assessed (€ 300, 2024 price level). If the wall behind it cracks as well, further investigation of the settlement with monitoring bolts follows (€ 1,500, 2024 price level).

What this shows: Cracks at an extension can have two causes: poor plasterwork or differences in settlement. A step-by-step investigation makes that distinction.

Case 34: Crack above the extension of a terraced house, Heemstede

Situation: Terraced house from 1923 with three storeys, no VvE. In October 2024 the client had an independent building inspection carried out, expressly without an additional foundation investigation.

Findings:

• Above the extension at the rear there is a crack in the brickwork that may indicate sinking or may have arisen when the extension was built.
• The moisture reading above the window frame at the front does not exceed the limit value, but is slightly higher than normal (€ 400, 2024 price level).
• At the balcony the timber substructure of the cover trim is affected by wood rot (€ 650, 2024 price level).
• In both bathrooms no earthing point could be found. The central heating boiler is at low pressure and inspection stickers are missing (€ 475, 2024 price level).
• Total € 5,625 (2024 price level).

Advice: Further investigation of the crack and floor levelling before signing the purchase agreement. Also leak detection at the plasterwork and a check of the earthing by a certified electrician.

What this shows: A crack does not have to mean a foundation problem, but the cause cannot always be established visually.

Case 35: Damp cellar and leaking bathroom at a detached house, Bloemendaal

Situation: Occupied detached house from 1906 with 3 storeys, no VvE. In July 2024 the client had an independent building inspection carried out.

Findings:

• Damp has come through the cellar walls all round; the cellar floor could not be inspected. According to the report, a watertight cellar requires a completely new concrete cellar: € 75,000 (2024 price level).
• The cellar window frames are probably severely affected by wood rot: € 1,600 (2024 price level).
• Damp patches show that the bathroom above is not watertight; no safety earthing was found in the bathrooms on the first floor (bathroom repair € 1,200, 2024 price level).
• Around pipes there is insulation material suspected of containing asbestos. Total estimated: € 95,005 (2024 price level).

Advice: Before signing the purchase agreement, have an asbestos survey and an additional investigation of the crawl space carried out. Have the safety earthing in the bathrooms checked by a certified electrician; the report advises against using the bathroom on the first floor.

What this shows: A single item, here the cellar, can make up most of the total repair costs. The shrinkage cracks in the plasterwork were assessed in the same report as not a cause for concern.

14. What we find in Haarlem and Kennemerland

We counted 263 of our own reports from Haarlem and the rest of Kennemerland, from 2018 up to and including October 2026. 68 per cent of the buildings with a known year of construction were built before 1940.

What we find or suspect during an inspection

In 156 building inspections in this region, these defects occurred most often:

• leaks or signs of leaks: 64 per cent;
• cracks: 58 per cent;
• wood rot: 47 per cent;
• subsidence or tilt: 25 per cent;
• rising damp: 21 per cent;
• suspected asbestos material: 17 per cent;
• missing or unsafe earthing: 12 per cent;
• mould: 10 per cent.

Rising damp occurs here about twice as often as the average across all our reports (11 per cent).

Repair costs in the report

In 101 inspections from 2024 up to and including 2026 with a cost overview, the median of the immediately necessary costs was about € 10,700. With the longer-term costs and the improvements added, it was about € 17,800. In 55 per cent the immediate costs came to € 10,000 or more, in 26 per cent to € 25,000 or more. For houses built before 1906 the median was € 21,600 (18 inspections), for houses from 1906 up to and including 1930 € 15,350 (40 inspections).

Foundation measurements

In 44 reports with a bed joint measurement or floor levelling, the median of the largest height difference measured was 30 mm. In 32 per cent it was 50 mm or more, in 9 per cent 100 mm or more.

How we counted

We used the same method as for all our reports: duplicate and empty reports removed, standard texts not counted, and a defect only counts if the inspector found or suspected it in that report. Costs and measurements come from our report software (2021 up to and including 2026), amounts including VAT at the price level of the year of the report. These are jobs that came in to us, not a sample of all houses in the region. The numbers are small; treat the figures as an indication. The figures for all our reports are in the premiumkeur.nl knowledge base.

Frequently asked questions

What does a building inspection in Haarlem cost?

€ 499 including VAT for a house up to 800 m³, plus € 0.50 per extra m³. That is the same rate as in Amsterdam.

How long does the inspection take and when do I get the report?

The inspection takes 1 to 1.5 hours on average. You will have the report within 2 working days.

Do you also inspect outside Haarlem?

Yes, throughout Kennemerland: including Heemstede, Bloemendaal, Zandvoort, Velsen, Beverwijk, Heemskerk and Castricum.

Should I have a foundation investigation done in Haarlem?

Our advice is yes for any house built before 1970. In Haarlem there are both shallow foundations and foundations on timber piles. A quick scan can be done during the inspection; together that costs from € 898.

What does foundation repair cost?

From € 2,500 per m², with a cellar from € 3,500 per m². The finishing work afterwards costs from € 3,000 per m².

Do you go into the crawl space and onto the roof?

Yes, if it can be done safely. We look at low crawl spaces with a robot with a camera.

Is tilt always a foundation problem?

No. A tilt can be old and have stopped. Monitoring bolts show over 2 to 5 years whether a building is still sinking.

Does an asbestos survey come with the inspection?

No. We do report suspected asbestos material. Have it investigated before you sign.

Can I use the report for my mortgage?

Yes. Premiumkeur is NHG accredited and NEN 2767 certified.

Do you work with estate agents?

No. We only work for buyers and owners.
