Our approach

We diagnose the cause, not just the symptom

Most damp problems are misdiagnosed because the symptom is treated instead of the mechanism. A failed gutter, a bridged damp proof course and a cold, poorly ventilated room can all leave the same stain on a wall.

We survey first, profile the moisture, inspect the timber and only then specify remedial work. That means smaller, more targeted jobs and no unnecessary chemical injection.
