Forensic damp & mould diagnosis

Finding the real cause of moisture — so you fix the problem once, not the symptom twice.

We don't sell the cure. No treatments, no damp-proofing, no building work.
The firm that diagnoses your damp shouldn't also be the one quoting to fix it. We only sell the truth about your building.

Diagnosis, not guesswork

Most "damp" is misdiagnosed. A free survey from a damp-proofing firm has one answer ready before they arrive — injection and replastering — because that's what they sell. We come at it the other way: comparative moisture readings, thermal imaging, dew-point and ventilation assessment to work out what's actually happening, whether that's condensation, a penetrating defect, a leak, a bridged DPC, or genuine rising damp (which is far rarer than the industry implies).

Every diagnosis is written up clearly, with the evidence behind it and plain-English recommendations. We never blame the tenant's lifestyle as a default, and we never recommend works we'd profit from — because we don't do works at all.
