Stop damp before it spreads

Damp rarely stays in one place for long. It can start as a faint musty smell, peeling wallpaper or a tide mark near the skirting, then lead to flaking plaster, mould growth and damage to walls or timber. We begin by finding the actual cause, because rising damp, condensation and penetrating moisture do not behave the same way and should not be treated the same way.

​

Our survey considers the warning signs in context, including moisture patterns, salt contamination, ventilation and external defects. Where rising damp is confirmed, we can inject a chemical damp-proof cream into the mortar course to create a barrier that limits moisture rising through the wall. Damaged or salt-contaminated plaster may also need to be removed and replaced so the repair is effective, not merely cosmetic.

How our survey and treatment process works

First, we inspect the affected areas and check the signs that point to the source of moisture. If a failed or missing damp-proof course is part of the problem, we explain the most suitable remedial option and what the work involves.

​

Where appropriate, a chemical damp-proof cream is injected into a mortar joint to form a barrier against rising moisture. We also check for salts and damaged plaster, because contaminated finishes can continue to attract moisture and cause problems after the wall begins to dry. Any necessary removal, preparation, replastering and moisture-control work is included in a clear treatment plan. Our damp-proof course systems are designed for long-term control, with a minimum life expectancy of 20 years when installed in suitable conditions. When you contact us in Durham, you get straight answers and a free survey without pressure.
