The right diagnosis saves money

A good survey is the foundation of every successful waterproofing or damp project. Without one, you risk paying for the wrong treatment. A new damp-proof course will not cure condensation, and tanking will not fix a leaking downpipe.

Our surveyors combine moisture readings with an experienced eye for London's period and modern construction. We look beyond the visible symptom to find the source, because the symptom often sits far from the cause. Then we set out what needs doing and why.

You end up with clarity: a written report you can act on, use in negotiations, or keep for peace of mind. For example, buyers often use it to agree a price reduction. Homeowners use it to compare quotes, since the report names the system required, such as damp proofing or basement waterproofing.

The survey also checks ventilation, drainage and external defects, because these often cause damp. As a result, many problems turn out to have a simple fix. If the cause is more serious, the report specifies the correct BS 8102 system and gives a fixed price.

On the visit, the surveyor tests walls with a moisture meter and looks for signs such as salts, mould and staining. In addition, they check outside for blocked drains, poor paving and damaged gutters.

After the visit, you receive a plain-English report. It lists what we found, what caused it and what to do next. Meanwhile, the quote gives a fixed price for any work, and you can take your time to decide.

A survey is worth it when

  • You have damp, mould or a musty smell and don't know why
  • A mortgage or building survey has flagged damp
  • You're buying a property with a basement or cellar
  • You've had treatment before that didn't work
  • You're planning a basement conversion
  • You want an independent second opinion

Survey FAQs

How much does a damp survey cost and is it free? +
For homeowners considering treatment, we provide a free survey with a written report and fixed quotation. Specialist surveys for pre-purchase, party wall or professional purposes may be chargeable — we'll tell you upfront which applies to your situation.
What does a professional damp survey include? +
Our surveyor inspects the affected areas, takes moisture readings, identifies the type and source of damp or water ingress, and considers ventilation, drainage and external defects. You receive a written report explaining the cause and a specification for the recommended remedial system.
Do I need a damp survey before buying a property? +
If a mortgage valuation or building survey has flagged damp, an independent specialist survey is well worth it. It tells you what the problem is, how serious it is and what it will cost to fix — useful information before you commit or negotiate.
Will you try to sell me treatment I don't need? +
No. An honest diagnosis is the whole point. Damp is frequently over-treated, and if your problem is condensation or a simple external defect we'll tell you — even if that means no remedial contract for us.
