Accurate Moisture & Timber Diagnostics for Properties in Dorset & Hampshire

What Is a Diagnostic Survey & Why It Matters

A diagnostic survey is a detailed investigation tailored to uncover the root causes of moisture and timber problems — not just the visible symptoms. Typical issues such as rising damp, penetrating damp or condensation often masquerade as simple claims of “damp walls”. But without the correct diagnosis, treatments can be ineffective or temporary.

Our process begins with a full inspection of the interior and exterior building fabric, using tools like moisture meters and thermal cameras. For example, thermal imaging can reveal cooler areas of wall surfaces caused by moisture evaporation — allowing us to target the precise cause rather than guess.

Once the source is identified, we produce a clear written report, with photographic evidence and repair recommendations, so you know exactly where to go next.
