A moisture and damp inspection is a detailed survey of your property to find the cause of damp patches, mould, staining or musty smells. Specialist equipment is used to measure moisture levels and identify whether the problem is condensation, rising damp, penetrating damp or leaks.

Without a proper inspection, it is easy to misdiagnose damp and waste money on the wrong treatments. A professional report gives clear evidence of what is causing the problem and what needs to be done to fix it.

Moisture and damp inspections are available across South Wales, including Cardiff, Newport, Swansea, Pontypridd, Caerphilly, Rhondda and nearby valleys. This means most homeowners and landlords in the region can book a survey without long waiting times.​

The surveyor will visually inspect affected rooms, take moisture and humidity readings, and check external elements such as walls, roofs and gutters where relevant. The findings are then written up in a report that explains the likely cause of damp and recommends practical remedies.

Condensation comes from excess moisture in the air settling on cold surfaces, while rising damp moves up from the ground through walls if the damp proof course has failed or is missing. Penetrating damp occurs when water gets through external walls or roofs because of defects like cracked render, porous brickwork or faulty gutters.

Most residential moisture and damp inspections are non‑invasive and use tools such as moisture meters and thermal imaging without damaging finishes. In rare cases, small test areas may be recommended where hidden leaks or structural issues are suspected, but this will always be discussed first.
