London Damp Surveys: Accurate Diagnostics, Lasting Solutions

A London damp survey is a professional inspection carried out to identify the cause of damp, moisture or water ingress within a property. Unlike general inspections, a damp survey focuses on diagnosing the underlying issue rather than treating visible symptoms.

With over 30 years of experience, Advanced Damp has resolved some of the most challenging damp problems across London, from condensation in modern flats to rising damp and salt contamination in Victorian and Edwardian terraces. Our specialists use moisture profiling, thermal imaging and invasive testing where needed to pinpoint the root cause of even the most severe damp issues.

By diagnosing problems early, we provide tailored damp proofing solutions to protect your property from long-term moisture damage and ensure a healthier, safer environment.

Why a Damp Survey Is Essential

Damp problems are often misdiagnosed. Treating symptoms without identifying the root cause can lead to unnecessary costs and repeat failures. That is why we always recommend a professional damp survey before any remedial works. The survey allows us to:

  • Identify the true cause of the issue
  • Rule out incorrect treatments
  • Recommend the correct solution
  • Avoid unnecessary works

This protects you as the property owner.

Frequently Asked Questions

How much does a damp survey cost in London?

The fee depends on the size and type of property, so we confirm a fixed price when you book. If you proceed with the recommended works, the survey fee is deducted from the cost of works, so the diagnosis effectively costs you nothing.

How long does a damp survey take?

Most residential surveys take between one and two hours on site, depending on the size of the property and the extent of the problem. Your written report with findings, diagnosis and a recommended treatment plan follows within 48 hours.

Do I need a damp survey before buying a property?

If a mortgage valuation or building survey has flagged damp, a specialist damp survey tells you exactly what the problem is and what it will cost to fix before you commit. It is one of the cheapest forms of protection available to a buyer, and the findings can support price negotiations.

What is the difference between a damp survey and a building survey?

A building survey (such as an RICS Level 2 or 3) covers the whole property at a general level and will usually only note that damp is present. A specialist damp survey diagnoses the specific cause, maps the affected areas, and sets out the correct treatment, which a general survey does not do.

Which areas of London do you cover?

We carry out damp surveys across all London boroughs from our central London office at 45 Fitzroy Street, including period properties in Fulham, Clapham, Islington, Hackney, Putney and surrounding areas, as well as the wider South East.
