What damp proofing in Cassiobury involves
Damp has a cause, and lasting damp proofing starts by finding it. Damp patches, blown plaster and a musty smell all point to moisture getting in somewhere, and the right treatment depends entirely on which kind you have.
Because we are roofers as well as damp proofing specialists, we spot when damp indoors is really a roof, flashing or gutter fault. You fix the real cause once, rather than treating a wall inside while water keeps coming in.
What a damp survey in Cassiobury covers
- Which type of damp it is, and where the moisture enters
- Roof, flashing and gutter faults feeding the problem
- Moisture readings across the affected walls
- How much plaster needs removing and reinstating
You get a written quote covering the treatment and the making good, so there is no open-ended bill at the end.
Damp proofing solutions we fit
Damp proofing walls properly means matching the treatment to the cause. Three problems account for most of the work we carry out across Cassiobury, and each one needs a different fix.
Rising damp
Moisture drawn up through the wall from the ground, showing as a tide mark low down. We install a new damp-proof course and reinstate the plaster above it.
Penetrating damp
Water crossing the wall from outside, often through failed pointing or render. We treat the wall, then protect it with waterproof coatings where it needs them.
Roof-related damp
Staining high on a wall or ceiling, worse after heavy rain. Usually a flashing, valley or gutter fault, which we can put right from the roof as well.
Damp proofing costs in Cassiobury
No damp proofing company can price a wall it has not seen. Four things decide what your job costs:
- The type of damp, and how far through the property it has spread
- Whether an external roof or gutter repair is part of the fix
- How much plaster has to come off and go back on
- Access to the affected walls and rooms
What our customers say
Damp Proofing in Cassiobury — your 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.What is damp proofing?
Damp proofing is any treatment that stops moisture moving into or through the structure of a building, and keeps it out afterwards. In practice it covers three different jobs: installing a damp-proof course where moisture is rising from the ground, sealing or protecting walls where water is crossing from outside, and fixing the roof, flashing or gutter fault where water is getting in from above. Treating the plaster without stopping the water only delays the problem, so proper damp proofing always starts with finding the source.How much does damp proofing cost?
Damp proofing is priced per property. The cost depends on which type of damp you have, how far it has spread, how much plaster needs removing and reinstating, and whether an external repair forms part of the fix. One wall treated and made good is a very different job from a whole ground floor. We survey the property first, tell you which type of damp you actually have, then put a fixed price in writing before any work starts.
