What the job involves
Because we are roofers as well, we are well placed to spot when interior damp is actually a roof, flashing or gutter problem letting water into the fabric of the building. That means you fix the real cause once, rather than treating the symptom indoors while water keeps coming in.
Where the issue is rising or penetrating damp, we install the right damp-proofing treatment and make good the plaster, so the wall recovers and the finish lasts.

What's included
- Complete damp survey to identify the type and source
- A check for roof, flashing and gutter faults feeding the problem
- Rising and penetrating damp proofing
- Affected plaster removed and reinstated where needed
- Condensation, ventilation and mould advice
- Waterproof rendering and brick coatings where walls need protecting

Everything we handle as part of your damp proofing, from first survey to final tidy-up.
Damp Proofing
Damp is far more than an unsightly problem. Left unchecked it can lead to health issues — respiratory problems and allergies from the growth of moulds and mildews — and it steadily erodes building materials, causing structural weaknesses. That is why damp proofing should be treated as a priority. We recognise the challenge damp poses to both the fabric of your property and the health of the people living in it, and our damp-proofing services are built to tackle the cause rather than just the symptom.

Damp Proofing questions
Why is damp proofing important?
Damp is more than an unsightly issue. It can lead to respiratory problems and allergies from moulds and mildews, and it erodes building materials over time, causing structural weaknesses — so it is worth treating as a priority.How do I know if my damp is from the roof?
Staining high on a wall or on a ceiling, worse after heavy rain, often points to a roof or flashing fault. As roofers we can check the roof and the interior together.Do you fix the cause or just cover it up?
The cause. Treating the plaster without stopping the water simply delays the problem, so we deal with the source first.What damp services do you offer?
Complete damp surveys, rising and penetrating damp proofing, commercial damp proofing, damp-proof flooring, condensation solutions, mould removal, ventilation and PIV systems, water-ingress protection, rendering and waterproof brick coatings.Will you make good the plaster afterwards?
Yes. Where damp has damaged the plaster we remove and reinstate it as part of the work.
