What Makes an Independent Damp Survey Different?

Most damp surveys are carried out by companies that also sell damp treatments — creating a clear conflict of interest. At Damp Surveyors Ltd, we are completely independent. We have no financial interest in recommending any remedial work, which means you receive an honest, accurate diagnosis you can actually trust.

  • No ties to damp-proofing contractors — your survey result is never influenced by a sales agenda
  • Detailed photographic reports with moisture readings delivered within 24–48 hours
  • Reports accepted by mortgage lenders, solicitors, estate agents and insurers
  • Advanced thermal imaging cameras detect hidden moisture non-invasively
  • Covering all of London, England and Wales — fast appointment availability
Proud members of the Federation of Damp — committed to the highest professional standards in independent surveying.

What is an independent damp survey?
An independent damp survey is a professional inspection carried out by a qualified surveyor with no financial interest in recommending any remedial work. Unlike surveys from damp-proofing contractors, an independent damp survey delivers an honest, unbiased diagnosis of rising damp, penetrating damp, condensation, timber decay and structural water ingress — without any sales pressure.
Free surveys from damp-proofing contractors carry a fundamental conflict of interest — the company surveying your property also profits from recommending treatment. Research and consumer watchdogs have repeatedly shown that contractor surveys overdiagnose rising damp and recommend expensive treatment where the real cause is condensation or a simple building defect. An independent damp survey removes that conflict entirely.
The cost varies depending on survey type, property size and location. We offer transparent fixed pricing with no hidden charges. Contact us for a free no-obligation quote — most clients find the fee of a professional independent damp survey is a fraction of the unnecessary treatment costs they avoid as a result.
Our independent damp survey includes a thorough inspection using calibrated moisture meters, hygrometers, carbide testing and FLIR thermal imaging cameras. You receive a comprehensive written report with photographs, moisture readings, root cause analysis and prioritised recommendations — delivered digitally within 24–48 hours of the inspection.
Yes. Our independent damp survey reports are accepted by all major UK mortgage lenders, solicitors, estate agents and property insurers. They are suitable for property purchases, price renegotiations, legal disputes, insurance claims and landlord compliance assessments.
A thorough independent damp survey typically takes 2–4 hours depending on property size and complexity. Our surveyors never rush the inspection — professional diagnostic accuracy is what sets our independent surveys apart from contractor assessments.
Yes. We use FLIR thermal imaging cameras as part of our independent damp surveys. Thermal imaging detects hidden moisture behind walls, under floors and within ceilings without invasive investigation — identifying cold bridges, insulation failures and concealed water ingress that standard moisture meters cannot detect alone.
We deliver all independent damp survey reports within 24–48 hours of the inspection by email in PDF format. Reports include photographic evidence, moisture readings, root cause analysis and clear actionable recommendations in plain English. For urgent transactions, advise us at booking and we will prioritise delivery.
