Injecting a chemical damp proof course into the mortar course of a brick wall

Damp proofing and property preservation services

Seven services covering damp, timber decay, water ingress and the reinstatement afterwards. Every one starts with a free survey so the work is priced against the actual cause.

Every service carried out by our own team

Nothing on this list is subcontracted out. That matters when a guarantee has to be honoured years later, because the people who did the work are the people who come back.
