Damp Inspection Checklist

How to use the Damp Inspection Checklist

1. Record immediate hazards first, including active leaks, electrics, bulging ceilings and contaminated water.
2. Add the building era and only identify traditional construction when it is known.
3. Tick observed patterns and completed external, service and environmental checks.
4. Add dated site notes, then print the structured investigation handover for a competent professional.

Why use this tool

• Makes urgent safety actions visible before routine damp investigation.
• Turns observations into proportionate inspection prompts without ranking alleged causes.
• Creates a useful factual handover while keeping diagnosis and treatment with competent site investigation.

Visible damp can arise from several interacting sources, including leaks, rain penetration, surface or interstitial condensation, ground moisture, salts and altered materials. A questionnaire cannot establish that source or safely prescribe injection, tanking, ventilation or removal. Check urgent leaks and hazards, preserve observations and obtain a competent site-specific survey; historic fabric needs appropriate conservation expertise.
