Moisture and leak inspection: finding the cause

Independent diagnosis with thermal imaging and moisture measurement. We do not sell injections or ventilation systems, only the facts. Fixed price, report within 5 working days.

Fixed price €395 excl. VAT

Moisture is a symptom, not the cause

Painting over it solves nothing

A damp patch on the wall, mould in the corner of the bedroom, a musty smell in the basement: these are symptoms. The cause is somewhere else. A leaking gutter, a broken pipe, rising ground moisture, a thermal bridge or simply too little ventilation. As long as that cause is not found, the moisture comes back, however often you repaint.

AC Vastgoed Advies establishes the cause with thermal imaging and moisture measurement, non-destructively. You receive a report with the cause per damp spot and repair advice with a cost indication. With that you request targeted quotes, without depending on the judgement of the company that wants to do the work.

When you need it

Four situations in which people call us

Home owners, tenants, buyers and boards of homeowners associations throughout the Randstad.

💧 Recurring damp patches

After repairs or repainting the moisture keeps coming back and nobody knows why.

🏢 Leak in an apartment

Unclear whether the cause is in your home, at the neighbours or in the common parts of the VvE.

🏠 Before or after buying

You saw traces of moisture at the viewing, or found them after the transfer and want to know what is going on. Often combined with a pre-purchase inspection.

📄 Insurer or counterparty asks for evidence

You need an independent report to substantiate a claim or a liability notice.

What we investigate

All forms of moisture, with measuring equipment

We measure instead of guessing. The thermal camera shows temperature differences that indicate moisture and leaks; the moisture meter establishes the moisture content. No drilling or opening up.

⬆️

Rising damp

Ground moisture that rises through the foundation and brickwork, recognisable by a tide mark and salt efflorescence at the bottom of the wall.

🌧️

Penetrating damp

Rainwater that penetrates the facade through porous brickwork, poor pointing or cracks.

🔧

Leaks

From the roof, the gutter, pipes, window frames or the bathroom of the upstairs neighbours. We locate the source.

❄️

Condensation and thermal bridges

Moisture that settles on cold surfaces due to insufficient insulation or ventilation. Often the cause of mould.

🔦

Crawl space

Water in the crawl space, a wet floor, damp beams and the consequences for the floor above.

📷

Thermal images and readings

Thermograms and measured values per location, so the diagnosis is reproducible and substantiated.

FAQ

Questions about the moisture inspection

A free damp survey is offered by companies that sell damp-proofing: injections, basement tanking, ventilation systems. The survey is the sales pitch. We do not sell any of that and have no interest in the outcome. You pay for an independent diagnosis and receive repair advice with which you can request quotes from whoever you choose.
No. We work non-destructively with a thermal imaging camera and a moisture meter. Temperature differences reveal moisture, leaks and thermal bridges; the meter establishes the moisture content of walls, floors and ceilings without damage. Only if the cause cannot be established this way do we advise destructive investigation, always agreed in advance.
This is common in apartments: a leaking roof, a shared pipe or the balcony of the upstairs neighbour. Our report states where the cause is and who is responsible: you, the neighbours or the VvE. If it comes to a dispute, we can extend the investigation into a damage report that holds up with lawyers, insurers and the court.
That depends on the cause and your policy. In case of a sudden leak, such as a burst pipe, many building and contents insurances cover the cost of tracing the cause. Rising damp, condensation and overdue maintenance are usually not covered. Our report is suitable as supporting evidence for your claim; check the cover with your insurer beforehand.
The report is written in Dutch, so that it can be used with Dutch insurers, contractors, the VvE and, if needed, in court. All communication is in English, and we explain the findings and the repair advice to you by phone in English.
