Our services
Rising damp
Tide marks, salts and crumbling plaster low on the wall. We install a new chemical damp proof course and replaster.
Penetrating damp & basements
Damp patches after rain, or water coming through basement walls. We stop it at the source with tanking and membrane systems.
Dry rot & wet rot
Soft skirtings, springy floors or a musty smell. We remove the decay, treat timber and masonry, and rebuild.
Woodworm
Small holes and fine dust in your timber. We confirm whether it’s active, treat it and replace weakened boards and joists.
Condensation & black mould
Streaming windows and mould that keeps coming back. We fix the cause with ventilation and thermal barriers.
Surveys & guarantees

What our customers say
Rated 4.84 out of 5 from 15 reviews on TrustATrader, where we’ve been a vetted member since 2017.
“A leak from my washing machine and an ever pervading musty smell of damp prompted me to call Denis. He came and examined the problem, offered a solution which has eradicated the smell and damp completely. On completion I was shown what had been done and given advice on how to reduce the humidity in my kitchen which was running well above the recommended 50%. I am exceptionally happy with Denis’ work, attention to detail and ensuring I was happy with the outcome. I would recommend Denis unreservedly.”
Mark B., April 2026 ★★★★★
“Denis visited us to advise on an ongoing problem we are experiencing in one of our bedrooms. He was very knowledgable – with a couple of quick assessments he was able to pinpoint our problem and suggested solutions that we will now put in place. I would 100% recommend Denis if you have a damp or condensation issue.”
Daniel F., November 2024 ★★★★★
“Arrived on time and competed the required works to the exterior extension wall to stop the water ingress and damp issues being experienced. Very friendly, polite & corteous. Thank you Denis”
David, November 2025 ★★★★★
