Highlights
A competent surveyor should understand fundamental building science, investigate the property thoroughly and use evidence to identify the true cause of moisture. Simply placing a damp meter against a wall is not enough to diagnose a problem.
The discussion covers:
- Why a proper damp survey cannot be completed in 20 minutes
- The limitations of relying solely on damp-meter readings
- Understanding capillary action and moisture movement
- Inspecting walls, subfloors, air bricks and external factors
- How gravimetric testing measures moisture content
- Why humidity data logging is more useful than a single reading
- Using vapour pressure to assess ventilation
- Avoiding unnecessary damp-proofing treatments
- Qualifications, reputation and recommendations
A good surveyor should be able to explain their diagnosis, provide evidence and justify any recommended work rather than relying on assumptions.
