FAQs

Damp Proofing FAQs

Common questions about damp proofing. Anything else, just ask.

01322 950271
How do you deal with damp?

We start by finding out whether the cause is rising damp, penetrating damp or condensation, then treat the source rather than the symptoms, with injection, waterproof coatings or ventilation as needed.

What are the signs of rising damp?

Tide marks on ground-floor walls, peeling wallpaper, salt deposits and rotting skirting boards, usually up to about a metre high.

Is black mould caused by damp?

Usually by condensation. We tackle it with a combination of ventilation, insulation and treatment rather than repeated cleaning.

How long do walls take to dry out after treatment?

It depends on the thickness of the wall and the time of year. We will advise you on when it is safe to redecorate.
