Damp Survey Cost Guide (Fees from £495)
A practical breakdown of damp survey costs, what is included, and why fees generally start from £495.
Why damp survey fees vary
Survey fees depend on scope, access and complexity—not just “how many rooms”. A professional damp survey is an investigation: it must explain the moisture mechanism and provide repair-first recommendations.
- Property size and access: lofts, basements, and tight sub-floor voids take time.
- Complex symptoms: mixed causes (leaks + condensation) require more evidence gathering.
- Construction type: solid walls, retrofits and extensions change how buildings manage moisture.
- Reporting standard: photographs, prioritised actions, and clear “why” behind conclusions.
What you should expect from a proper damp survey
- Internal and external inspection to trace likely pathways.
- Moisture profiling and contextual interpretation (patterns, ventilation, thermal risk).
- A written report with photos, priorities, and practical next steps.
- Clear separation between diagnosis and remedial selling (independence matters).
If a “survey” is free or very cheap, it is often a sales visit. That can lead to generic recommendations and unnecessary treatments.
How to compare quotes fairly
Before you book, ask for these specifics in writing:
- What areas will be inspected (including external elevation checks)?
- What evidence will be provided (photos, moisture mapping, defect notes)?
- Is the surveyor independent (no products, no remedial commission)?
- What is the report turnaround time?
FAQs
Is £495 the typical price for a damp survey?
Fees generally start from £495 for a standard scope. Larger or more complex properties may cost more; the key is matching scope to the problem.
