The difference treatment makes
A dry wall changes everything.
Damp damage can leave rooms stained, flaky and difficult to live in. Our first step is to understand why the wall is wet; only then do we recommend treatment and the right finish.

Damp will not go away on its own
Once damp gets into a building it keeps spreading – damaging plaster, decoration and the value of your home. It cannot be hidden from a surveyor, and ignoring it only makes the repair bigger.
As a family-run business with over 30 years' experience, we give homeowners and landlords honest advice and a treatment tailored to the property.

Tide marks, crumbling plaster and lifting skirting boards are classic signs of rising damp. We confirm the cause with a free survey, install a new damp proof course using a BBA approved system and replaster with salt-resistant materials. Read more about our rising damp treatment.

When can I call you?
We are open 24 hours. Call 07803 253337 or 0800 593 0300.
Can damp in a house be fixed?
Yes. Identify the moisture source first, then address the relevant leak, rainwater defect, rising damp or condensation. Damaged plaster and decoration may need repair after the source is controlled.
Can damp proofing be done from inside?
Some work, including suitable DPC injection and necessary plaster repairs, can be carried out internally. Access and wall construction determine the method; an inside finish alone cannot repair water entering elsewhere.
Can damp proofing be done from outside?
Often. Outside work may include suitable DPC installation or repairs to the rainwater route. The survey considers access, materials and ground levels before recommending the approach.
Can damp proofing fail?
A treatment can disappoint if the wrong source was diagnosed, a moisture bridge remains or new water entry develops. Have renewed damp assessed and keep your treatment specification and guarantee paperwork available.
For business premises, read our commercial damp proofing information and ask Seth about service availability.
