Building inspection Amstelveen: knowledge base
In brief
Premiumkeur Amstelveen inspects homes in Amstelveen, from post-war family houses to apartments and 1930s houses. Premiumkeur Amstelveen is part of Premiumkeur B.V., an independent building advisory firm with its head office in Amsterdam (Chamber of Commerce (KvK) 81106130).
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, and we are NHG-recognised (National Mortgage Guarantee) and 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 Amstelveen: the inspection, the costs, foundations, damp in the crawl space, roofs, owners' associations (Vereniging van Eigenaars, VvE) and the purchase agreement. Practical cases follow, taken only from our own reports from Amstelveen. 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 check: we look, measure and take photos, but we do not open anything up. The inspector goes 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 or cellar, if it can be reached: floor joists, moisture content, ventilation, pipes and the visible part of the foundation.
- Façades, 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 a specialist firm investigate it before you sign.
The report
For each building element you receive photos, a condition score under 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 subject to a building inspection condition (voorbehoud) and call straight after the verbal agreement. The condition usually runs for only a few weeks. If you attend the inspection, you see what the inspector sees and you understand the report better afterwards. It is not compulsory. If you already have a report from another firm and you have doubts, we can do a second opinion (contra-expertise), from € 599.

What repair costs
The report gives a cost indication for each defect. For foundation repair we give a price per m², not a total, because the differences between properties are large. Foundation repair costs from € 2,500 per m², with a cellar from € 3,500 per m². The finishing work afterwards costs from € 3,000 per m². Drawings and permit cost € 10,000 on average.
3. Building and living in Amstelveen
Most of the homes we inspect in Amstelveen were built between 1955 and 1975. We also inspect 1930s houses and apartment complexes built after 1990. What stands out in our reports from Amstelveen:
- In houses from the 1950s and 1960s the problem is often the age of the building elements themselves: crumbling or weathered pointing, cast-iron drainage, flat roofs and central heating boilers at the end of their service life (cases 1, 2, 10 and 15).
- Concrete gutters from that period can have concrete rot (betonrot) (case 5).
- In crawl spaces we see mould and damp, often because ventilation openings have been closed off (case 6), and crawl spaces that cannot be reached (case 1).
- In older houses on clay and peat the foundation can subside; in a house from 1938 we measured an 83 mm difference in height (case 4). An extension without a pile foundation sinks away from the house (case 14).
- Not every crack is a foundation problem. In cases 7 and 13 the cracks were caused by a bathroom floor that was too heavy and by shrinkage.
- In homes built before 1994 suspected asbestos material is found; we report this in the report (case 8).
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 façades, sloping joints, cracks above windows and doors, sticking doors and sloping floors. A clear difference with the neighbours is also a sign. Cracks can have other causes too, such as shrinkage, a missing lintel or a subsided extension. Only measurements show whether the foundation is the cause.
The foundation label (funderingslabel)
Since 1 April 2026 every valuation report has contained 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
- Quick scan (phase 0): bed joint measurement and floor levelling during the inspection. Together with the inspection from € 898; the quick scan itself then costs € 399.
- Phase 1: more extensive investigation above ground, € 699 to € 1,499, depending on how in-depth the investigation is. Archive research costs extra.
- Phase 2: the foundation is excavated and examined up close. From € 3,000, excluding excavation.
- Measuring bolts: 8 to 10 bolts for € 1,179. After 2 to 3 years of measuring you know how fast the property is subsiding.
A tilt is a snapshot. If a property subsides evenly by less than 1 to 2 mm per year, further investigation is usually not needed. At more than 2 mm per year, phase 1 or phase 2 follows.
Who pays for repair?
In an apartment building 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 a share.
More about foundation investigation can be found in the foundation investigation knowledge base.
5. Crawl space, damp, wood rot and dry rot
Many post-war homes in Amstelveen have a crawl space. If the ventilation openings are closed or the crawl space cannot be reached, moisture lingers. This causes mould and, in time, wood rot (cases 1 and 6).
How we inspect the crawl space
We go in ourselves and examine the floor joists and floor boards for wood rot, dry rot (huiszwam) and woodworm. We measure the moisture content with calibrated moisture meters; dry wood is 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
| Defect | What it is |
|---|---|
| Beam end rot | Rot at the end of floor joists that sit in a damp wall |
| Wood rot | Decay of wood caused by long-term moisture |
| Woodworm | Damage from beetles feeding, especially in poorly ventilated crawl spaces |
| Dry rot | Mould in very damp, poorly ventilated spaces |
| Rising damp | Moisture that rises from the ground up into the wall |
| Penetrating damp | Rainwater that comes in through the façade |
| Mould | Black spots caused by condensation or too little ventilation |
6. Roof, façade and equipment
We go onto the roof if it is safe. For difficult leaks we use a cherry picker or scaffolding at extra cost.
What we often see on roofs and façades
- Flat roofs and roofing at the end of their service life.
- Concrete gutters with concrete rot.
- Crumbling pointing and loose roof tiles.
- Sash windows and frames with overdue maintenance.
- Sealant and connections at dormers.
Equipment
| Equipment or method | Use |
|---|---|
| Moisture meters | Moisture content of beams, floor boards and walls |
| Bed joint measurement and floor levelling | Measuring tilt and subsidence |
| Endoscope | Looking into flues, cavity walls and closed-off crawl spaces |
| Infrared camera | Making leaks and poor insulation visible |
| Smoke generator | Finding the source of a leak or odour |
| Hydrogen detector and ultrasonic detection | Leaks in water and central heating pipes |
| Dye test | Leaks in drains |
| Crawl space robot with camera | Crawl spaces lower than 20 cm |
7. Service life of building elements
These are guideline values. How long something really lasts depends on quality, location and maintenance.
| Building element | Guideline value |
|---|---|
| Central heating boiler | 12 to 15 years |
| Zinc gutter | 20 to 30 years |
| Bituminous roofing | 20 to 25 years |
| EPDM roofing | around 40 years |
| Smoke detector | maximum 10 years |
| Sealant joints in bathroom and kitchen | renew about every 6 years |
| Exterior painting | every 6 to 8 years |
8. Apartments, VvE and long-term maintenance plan
When you buy 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 Land Registry (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 condition. If the repair costs exceed the agreed amount, you can terminate the agreement free of charge.
| Term | What it means for you |
|---|---|
| Duty to investigate | The seller discloses defects he knows about. What you could have seen in a reasonable inspection is usually at your own expense. |
| Termination condition for the building inspection | The purchase only goes ahead if the repair costs stay below an agreed amount. |
| Threshold amount | Often around € 5,000. It is not mandatory. |
| Statutory cooling-off period | Three days after receipt of the signed purchase agreement (Article 7:2 of the Dutch Civil Code). |
| Age clause | The home is old and may have defects that come with that. |
| As is, where is | You buy the home as it is, without guarantees. |
| NHG | Our inspections are NHG-recognised; you can use the report for your mortgage lender. |
10. Choosing an inspector
As a buyer you may choose an inspector yourself. An inspector recommended by an estate agent may have a business arrangement with that agent. So ask whether the inspector pays the agent a fee.
In the Netherlands anyone can call themselves a building inspector. What an inspection covers differs per firm and is set out in the general terms and conditions. Read these before you sign. Investigative journalist Bram Logger wrote about this in The small print of the 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 receive a fee if he refers me to you?
Premiumkeur does not accept assignments via estate agents and does not pay for referrals. We also do not recommend contractors or roofers: that way we have no interest in who carries out the repairs.
11. Specialist investigation 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 or demolition takes place, at your property or at the neighbours'. € 499 (case 9).
- Long-term maintenance plan for a VvE or another building (case 11). For a small VvE (maximum 5 apartments) € 899.
- Handover inspection for new-build or after a renovation: € 499.
12. Practical cases from Amstelveen
These cases come from our own reports, 2021 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: Flat roof past its service life and inaccessible crawl space, Amstelveen
Situation: Unoccupied terraced house from 1961 with three storeys and a roof extension added later, no owners' association (VvE). The client had a building inspection carried out in August 2026.
Findings:
- According to the client, the bituminous roof covering was fitted around 2000 and has therefore exceeded its theoretical service life of 20 to 25 years; € 8,500 is included for preventive replacement (price level 2026). Cracking was seen around the roof extension, while the inside appears to have been painted recently. The crawl space was not accessible and the facade has no ventilation openings for the crawl space. The foundation risk was assessed as low (class B). In total, € 13,500 in direct costs is included (price level 2026).
Advice: Request the structural drawings, calculations and permit documents for the roof extension and, if in doubt, have a structural engineer look at it before signing the purchase agreement. Have the crawl space made accessible and inspected.
What this shows: Fresh paintwork can hide older cracks; with a roof extension, the structural parts then become more important. Without an accessible crawl space, the floor type and floor condition remain unknown.
Case 2: Eroded pointing and central heating boiler past its service life, Amstelveen
Situation: Unoccupied terraced house from 1958 with three storeys, an extension and a roof extension, no VvE. The client had a building inspection carried out in August 2026, including a foundation risk assessment.
Findings:
- The pointing is eroding in many places and is missing in some; € 275 is included for immediate work and € 3,000 for the longer term (price level 2026). The central heating boiler dates from 2010 and has exceeded its service life of 12 to 15 years; € 2,000 is included for replacement in the longer term (price level 2026). The timber floor joists in the crawl space had a moisture content of around 12%, which is considered dry. Because of the extension, the original ventilation openings at the rear are gone. Bed joint measurements and floor levelling gave a low foundation risk (class B).
Advice: Have the pointing repaired locally and plan renewal in the longer term; have the boiler serviced and the flue checked. Improve the crawl space ventilation as soon as moisture problems occur.
What this shows: An extension can close off the ventilation of the crawl space, even when no moisture problems are visible yet. A house that is level can still need maintenance to the facade and installations.
Case 3: Rusting crawl space hatches in an apartment complex, Amstelveen
Situation: Apartment complex from 2002, with a VvE; the number of storeys is not stated. The reason for the crawl space inspection in August 2026 was moisture and condensation problems around the access hatches in the communal hall.
Findings:
- There is considerable corrosion on the steel frames around the access hatches; the hatches are warped or swollen and are stuck. On this side of the hall there is no or insufficient ventilation of the crawl space compartments. Around pipe penetrations the floor insulation has been removed in places and openings are not properly sealed. A considerable amount of construction waste was lying in the crawl space.
Advice: Replace both hatches and frames with insulated, airtight hatches, add extra crawl space ventilation through the facade, seal the penetrations, restore the insulation and remove the construction waste. Consider mechanical ventilation only if natural ventilation does not help enough.
What this shows: Even with a young, insulated floor, hatches and penetrations can form cold bridges where condensation occurs. Here the moisture problems had several causes, which need to be tackled together.
Case 4: House with 83 mm of subsidence on clay and peat soil, Amstelveen
Situation: Occupied end-of-terrace house from 1938 with three storeys, no VvE. The client had a building inspection carried out in March 2026 with a supplementary foundation quick scan (phase 0).
Findings:
- According to the bed joint measurement, the house is subsiding towards the right-hand side, with a maximum deviation of around 83 mm; on the second floor a height difference of around 44 mm was measured. The borehole profiles obtained show mainly clay down to a depth of around 2 to 7 metres, with a peat layer. Cracks were seen above the bay window and in the front facade; the subsidence falls in the moderate to high risk category. The cellar is not watertight (improvement € 12,000) and in total € 25,100 in direct costs is included (price level 2026).
Advice: If you want certainty, have a foundation investigation phase 2 carried out on the piles; with a shallow foundation (op staal), measuring bolts will give more insight over around five years. Allow for an increased risk of foundation repair.
What this shows: A raised shed and an extension put extra load on poorly load-bearing ground, which can make existing subsidence worse. Measurements above ground give an indication, not a guarantee.
Case 5: Concrete rot (betonrot) in the concrete gutters of a terraced house, Amstelveen
Situation: Unoccupied terraced house from 1964 with three storeys, no VvE. The client had a building inspection carried out in September 2025, without a supplementary foundation investigation.
Findings:
- Concrete rot was observed in the concrete gutter structures; at the rear the concrete slab has cracks, sags and water remains standing in the gutter. € 1,250 is included for repair of the visibly affected parts (price level 2025). A moisture measurement indicated an active leak and older, exposed wiring was found in the house. The window frames mostly have single glazing; replacement is estimated as an improvement at € 27,500, in addition to € 18,400 in direct costs (price level 2025).
Advice: Have the concrete gutter slab checked before signing the purchase agreement, because full replacement could be a considerable setback. Have the leak investigated by a leak detection company and have the electrical installation made safe by an electrician.
What this shows: A sagging concrete gutter with cracks and standing water is a reason to have a specialist look at it before purchase. In this house double glazing did not fit in the existing frames, so making it more sustainable meant full replacement.
Case 6: Mould growth in the crawl space and sealed-up ventilation, Amstelveen
Situation: Occupied end-of-terrace house from 1960 with three storeys, no VvE. The client had a building inspection carried out in June 2025, without a supplementary foundation investigation.
Findings:
- A lot of white, root-like growth was found in the crawl space on the concrete floor and against the inner walls, probably mould or fungal growth. The crawl space could not be entered, so the floor type was not determined and a known problem floor could not be ruled out. The ventilation openings in the facade have been pointed over, probably during retrofit insulation, and efflorescence from rising damp is visible just above ground level. For the pointing, € 1,200 is included for immediate work and € 5,500 for the longer term, with € 5,225 in direct costs in total (price level 2025).
Advice: Have the growth in the crawl space investigated by a specialist company before signing the purchase agreement and improve the ventilation. Have the moisture in the facade investigated by a specialist and the missing pointing repaired.
What this shows: Retrofit insulation can close off the ventilation of the facade and crawl space, with moisture problems as a possible result. A crawl space that cannot be entered leaves important questions open.
Case 7: Cracks caused by an overweight bathroom floor, not by the foundation, Amstelveen
Situation: Occupied end-of-terrace house from 1934, two storeys with a cellar, no VvE. In May 2025, cracking was assessed for a link with the foundation.
Findings:
- There are moderate to severe cracks in the rear facade and the balcony landing. On the front facade 6 mm was measured over 6,000 mm (rotation 1:1000) and on the side facade 6 mm over 10,220 mm (1:1703), both in the category 'negligible'. The rowlock course above the window frame under the balcony has dropped 12 mm over 1,900 mm (1:158, 'moderate'). On the second floor the floor slopes 23 mm over 2,800 mm (1:121) towards a bathroom with an unusually thick cement or concrete floor.
Advice: Monitor the cracks with crack gauges. If they grow by more than 3 mm per year, have the structure above the window frame calculated and replace the bathroom floor with a lighter version.
What this shows: Severe cracks do not have to come from the foundation. If the subsidence does not show up in the floors and facades below, local overloading is a more likely cause.
Case 8: End-of-terrace house with a leak stain in the meter cupboard and suspected asbestos materials, Amstelveen
Situation: Occupied end-of-terrace house from 1956, three storeys and a cellar, no VvE. Purchase inspection with a phase 0 foundation quick scan, April 2025.
Findings:
- The bed joint measurement shows height differences of 2, 4 and 5 mm per facade. The floor levelling gives differences of 1 to 7 mm, within the usual tolerances. In the crawl space the floor joists have a moisture content above 14%, against a normal level below 12%; wood rot was not seen. At the top right of the meter cupboard there is a clear leak stain, probably from the bathroom above (€ 500 for leak detection, price level 2025). Total direct costs: € 10,800 (price level 2025).
Advice: A supplementary foundation investigation is not needed now. Before signing, check that the leak has been fixed for good and have the suspected asbestos materials inventoried.
What this shows: A foundation quick scan (phase 0) can make a supplementary foundation investigation unnecessary if the height differences are small. A leak above the meter cupboard, because of the combination of water and electricity, is a risk that must be cleared up before purchase.
Case 9: Baseline survey (nulmeting) before building work next door, Amstelveen
Situation: Occupied semi-detached house from 1957 with two storeys, no VvE. A baseline survey was carried out in February 2025 because the house next door is going to be renovated.
Findings:
- Facades and most rooms are in good condition, with no signs of leaks or cracks. In the rear facade at the party wall there is a settlement crack; according to the client it has been there for years and has not grown. Above the garden door in the kitchen there is a shrinkage or settlement crack, and under the stairs there are slight shrinkage cracks in the plasterwork. The shed, a half-brick wall, shows subsidence and cracks and is sensitive to vibrations. In the loft a purlin for a roof window has been sawn through without proper support.
Advice: Have the sawn-through purlin properly supported structurally after all. Repair the shed in the longer term.
What this shows: A baseline survey records existing cracks before the neighbours start building, so that it can be seen later whether new damage has been added. At places without an expansion joint some cracking is to be expected and does not automatically point to a foundation defect.
Case 10: Terraced house with poor pointing and a cast iron drain in the meter cupboard, Amstelveen
Situation: Occupied terraced house from 1958, three storeys, no VvE. Purchase inspection with foundation investigation, December 2024.
Findings:
- The bed joint measurement shows that the front facade is 7 mm lower on the right than on the left; no difference was measured on the rear facade. The floor levelling gives 8 mm on the ground floor and one measurement of 15 mm that is not entirely reliable, and a maximum of 11 mm on the upper floors. The pointing is very poor and lintels are missing above the window frames (€ 5,000, price level 2024). In the meter cupboard there is a corroded cast iron drain to which lead pipes appear to connect; no costs are included for this. Total direct costs: € 13,100 (price level 2024).
Advice: Have the drain investigated before signing the purchase agreement; replacement may mean a bathroom renovation. When repointing, have lintels fitted as well.
What this shows: Small height differences of a few millimetres do not point to a foundation problem. The biggest financial risk can lie in pipework that is hidden in the structure.
Case 11: Long-term maintenance plan (MJOP) for a clubhouse with serious backlog maintenance, Amstelveen
Situation: Clubhouse with canteen and changing rooms from 1974, two storeys, no VvE. Long-term maintenance plan in November 2024, assuming long-term retention.
Findings:
- The roof of around 400 m² has a roof covering in very poor condition (€ 50,000 immediate, price level 2024); for the terraces another € 11,000 is added (price level 2024). Because the terraces leak there is concrete rot, and where the terrace joins the main building there are structural defects (€ 2,000 and € 4,000, price level 2024). The fencing does not comply with the Building Decree and is unsafe for small children (€ 6,000, price level 2024). In total the direct costs come to € 106,700, with another € 65,000 for new window frames in 2029 (price level 2024).
Advice: Renovating is more sustainable than patching up. Remove the old roof covering completely and repair the concrete rot only once the terraces are watertight.
What this shows: Repairing concrete rot only makes sense once the cause, water getting in, has been removed. With serious backlog maintenance, renovating can be cheaper in the long term than repairing again and again.
Case 12: Sliding windows and flat roofs of an apartment complex, Amstelveen
Situation: Occupied apartment complex from 1999 with a VvE. In March 2024 the VvE asked for an investigation of the sliding windows and the roof covering.
Findings:
- The sliding windows and the mechanism are in good condition; according to the report, better glazing saves at most € 5 per month per apartment in energy costs (price level 2024). The bituminous roof covering shows crazing, but can last at least another 5-10 years. A steel structure on the roof has been finished carelessly with coating and sealant, not in line with good workmanship. The concrete floor is insulated on the underside with 7-8 cm of polystyrene, against 14 cm under the current standard.
Advice: The roof covering does not need to be replaced yet; do have the upstands, sealant joints and the steel structure repaired so that they are watertight. Renew the glazing sealant where necessary and ensure better ventilation of the crawl space.
What this shows: Replacement is not always needed: targeted repair of weak spots can make a roof last years longer. Making a building more sustainable sometimes yields too little to earn back the investment.
Case 13: Shrinkage cracks unrelated to the foundation, Amstelveen
Situation: Occupied family house with three storeys, no VvE; the year of construction is not in the report. In December 2023 the client asked for an independent crack investigation.
Findings:
- The cracks are mainly in internal corners, on the joints of plasterboard, along window frames and under and next to the timber staircase. In several places the plasterwork has come loose because it did not bond to the base coat. At the bathroom threshold there is a small damp patch, because the threshold has not been sealed watertight. During painting, timber trims were not cut loose from the plasterwork. According to the conclusion, the cracks have nothing to do with the foundation.
Advice: Cut out the internal corners and the joints at window frames and staircase, fill them with acrylic sealant and paint over them. Have loose plasterwork removed and applied again, and fit a properly sealed threshold in the new bathroom.
What this shows: Cracks in a house do not automatically point to a foundation problem. Shrinkage and expansion at internal corners, together with mediocre plasterwork and paintwork, explain the cracks here.
Case 14: Extension without pile foundation at an end-of-terrace house, Amstelveen
Situation: Unoccupied end-of-terrace house from 1972, three storeys, no VvE. Purchase inspection in August 2022.
Findings:
- According to the building drawings, the extension does not stand on piles, and there is a high chance that it will subside in the longer term. The floor of the extension is not level and may be affected by moisture; there is rising damp in the rear facade by the extension. € 25,000 is included for founding and refinishing the extension (price level 2022). The crawl space was full of water and could only be inspected to a limited extent. In total the direct costs come to € 30,040 (price level 2022).
Advice: Have the floor of the extension investigated further; underpinning on piles means the extension has to be largely demolished. Have the drainage checked with a smoke test.
What this shows: Building drawings can show how an extension is founded, something you cannot see in a visual inspection. An extension without piles next to a house that does stand on piles can subside in the longer term.
Case 15: Vacant family house with a major renovation task, Amstelveen
Situation: Unoccupied family house from 1966, three storeys, no VvE. Inspection in November 2021 with a view to renovation.
Findings:
- The crawl space was largely under water and could therefore only be inspected to a limited extent; concrete rot in the foundation beam cannot be ruled out (€ 3,500, price level 2021). Damp patches were seen in the loft: in several places rainwater seeps in. The dormer is structurally and economically written off, with wood rot and leaks at the windows (€ 16,000, price level 2021). The electrical installation and fuse box must be fully renewed (€ 5,000 and € 1,200, price level 2021). Total direct costs: € 69,450 (price level 2021).
Advice: Have the crawl space pumped out, the pipework renewed and the ground covered with at least 20 cm of shells. Have asbestos removed before the renovation.
What this shows: A wet crawl space makes a full inspection impossible and is also a safety risk. In a house that still has to be done up completely, the costs for installations quickly add up.
13. Figures
In Amstelveen we have had around 26 reports in our report software since 2021, of which 14 are building inspections. That is too few to give reliable percentages per defect. The figures across all our reports, such as how often we find wood rot, cracks or leaks and what repair costs on average, are in the knowledge base of premiumkeur.nl.

Frequently asked questions
What does a building inspection in Amstelveen 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.
What should I look out for in a house from the 1960s?
The service life of building components: flat roofs, pointing, drainage, window frames and the central heating boiler. Also look at the crawl space and at suspected asbestos material.
Should I have a foundation investigation done in Amstelveen?
For a house built before 1970 we recommend it. A foundation 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.
Is every crack a foundation problem?
No. Cracks can also be caused by shrinkage, an overweight floor or a missing lintel. Measurements show whether the foundation is the cause.
Is an asbestos inventory part of the inspection?
No. We do report suspected asbestos material. Have it investigated before you sign.
Do I have to be present at the inspection?
You do not have to be, but we do recommend it. You then see for yourself what the inspector sees and understand the report better afterwards.
Do you work with estate agents?
No. We only work for buyers and owners, and we do not recommend contractors either.
