Damp Diagnosis Assistant
Narrow down the likely cause of your damp problem
Moisture problems are easy to misread, and the wrong fix can be expensive. This assistant asks a short series of questions about where the problem is, when it is worst and how it behaves, then uses a transparent set of rules to suggest the most likely causes — always alongside the alternatives worth ruling out.
How to read the results
The result lists the most likely cause with the specific observations that support it, plus other possibilities and important alternatives. Treat it as a structured starting point for your own investigation, not a verdict. It never diagnoses from a photograph and never shows invented confidence percentages.
Important
This assistant is a structured starting point, not a professional diagnosis or building survey. It never identifies a problem from a photograph. For extensive, structural or recurring damp, get an independent assessment from a surveyor who is not selling the treatment.
Frequently asked questions
No. It is a rule-based questionnaire to help you think clearly about the likely causes. A reliable diagnosis often needs an on-site inspection with a moisture meter and, sometimes, deeper investigation.
