A bouwkundige keuring (structural inspection) is your insurance policy against buying a money pit. For €400-800, a certified inspector examines the property's structural integrity, identifies hidden defects, and gives you negotiation leverage—or a reason to walk away.
Quick Summary
- • Structural inspections cost €400-800 and take 2-3 hours on-site
- • 15-20% of pre-1980 homes reveal major defects (€10,000+ repairs)
- • Foundation issues, roof leaks, and illegal extensions are most common
- • Always negotiate an inspection clause into your koopakte before signing
- • Inspection reports are valid for renegotiation or contract cancellation
What Does a Structural Inspector Check?
A certified inspector (VBO or NRVT registered) examines 200+ checkpoints across the property, from foundation to roof. The inspection typically takes 2-3 hours and results in a detailed report with photos, risk ratings, and cost estimates.
🏗️ Structural Elements
- • Foundation (cracks, settlement, moisture)
- • Load-bearing walls and beams
- • Floor joists and structural timber
- • Roof structure and trusses
- • Chimneys and masonry
💧 Water & Moisture
- • Rising damp and penetrating moisture
- • Roof leaks and gutter condition
- • Basement waterproofing
- • Drainage and groundwater issues
- • Condensation and ventilation
⚡ Installations
- • Electrical system (age, safety, capacity)
- • Plumbing and water pressure
- • Heating system (boiler, radiators)
- • Ventilation and air quality
- • Hot water system
🪟 Building Envelope
- • Windows and doors (condition, sealing)
- • Insulation quality and coverage
- • Exterior walls and cladding
- • Roof covering (tiles, shingles)
- • Gutters and downspouts
Red Flags: When to Walk Away
Not all defects are deal-breakers, but some issues are so severe or expensive that walking away is the smartest move. Here are the critical red flags that should make you reconsider:
🚨 Foundation Failure
Cost to fix: €30,000-150,000+ | Repair time: 3-12 months
Severe cracks, tilting walls, or sinking floors indicate foundation collapse. Common in Amsterdam (wooden piles rotting) and Rotterdam (soft soil settlement). Requires underpinning or complete foundation replacement.
⚠️ Illegal Extensions
Risk: Municipality can force demolition | Mortgage impact: Banks may refuse financing
Unpermitted additions (extra floors, rear extensions) without building permits. You inherit the legal liability and may be forced to remove them or face fines.
🔥 Electrical Fire Hazards
Cost to fix: €5,000-15,000 | Safety risk: Immediate fire danger
Pre-1970 wiring without grounding, aluminum wiring, or overloaded circuits. Insurance companies may refuse coverage until fixed.
Negotiation Strategy After Inspection
Once you have the inspection report, you have three options: renegotiate the price, demand repairs, or cancel the contract. Here's how to approach each:
Price Reduction Strategy
Request a discount equal to 100-150% of the estimated repair cost. The extra 50% accounts for your time, hassle, and risk of cost overruns.
Example Calculation:
- • Inspector estimates €20,000 for roof replacement
- • You request €25,000-30,000 price reduction
- • Seller counters at €22,000 → You accept
Key Takeaways
- →Always get an inspection for existing homes—15-20% reveal major defects worth €10,000+ in repairs.
- →Negotiate the inspection clause into your koopakte before signing—it's your only legal way to renegotiate or cancel.
- →Foundation issues, illegal extensions, and electrical hazards are the top three reasons to walk away from a deal.
