Book Damp SurveyFind a Damp Proofing Specialist Near You
A damp specialist diagnoses the cause of moisture and treats it. The diagnosis is the valuable part: condensation and penetrating damp are far more common than true rising damp, and both have different and usually cheaper remedies. A survey commissioned from the same firm that would carry out the remedial work is not an independent survey, and a second opinion frequently changes the answer.

Quick answer
What does a damp proofing specialist do, and is your damp actually rising?
A damp specialist diagnoses the cause of moisture and treats it — injected damp-proof courses, tanking, or ventilation. Work typically runs £500–£3,000. The important part is the diagnosis: condensation and penetrating damp are far more common than true rising damp, and they have different, usually cheaper, fixes. Insist on an independent survey before you accept a chemical DPC quote.
The three damps — how to tell them apart before you pay for the wrong fix
| Symptom | Rising damp | Penetrating damp | Condensation |
|---|---|---|---|
| Height on the wall | Under ~1m only | Any height | Any height |
| Worse after heavy rain | ⚠️ Sometimes | ✅ Distinctly | ❌ No |
| Black spotted mould | ❌ Rare | ⚠️ Sometimes | ✅ Typical |
| Worst in winter, cold walls | ⚠️ Sometimes | ⚠️ Sometimes | ✅ Typical |
| Usual fix | Injected DPC | Repair the defect | Ventilation and heat |
A survey from the same firm that will do the remedial work is not an independent survey. If a chemical DPC is recommended, an independent damp surveyor’s second opinion costs a fraction of the treatment and frequently changes the answer.
