Damp Proofing in Sunderland, Newcastle, Durham, South Shields, Gateshead & Chester Le Street. Rising damp is most commonly found in older buildings where the original damp proofing has either failed or has been incorrectly installed. Left untreated it is not only unsightly, but it can seriously damage your property.
Penetrating damp is quite simply moisture that passes through the roof or walls of a building from an outside source, and is often associated with defects in construction or plumbing. Generally, it is caused by water escaping from broken or damaged pipes or plumbing. Causes to look for might be cracked or obstructed gutters and overflow pipes, insufficient waterproofing, flawed pointing or brickwork, or defective windows and doors.

I would definitely highly recommend this firm. Work was done to a high standard and quickly. They arrived on time on a day that suited us and were really helpful and friendly, they even helped us fix something that was nothing to do with the job we'd booked them for!! I thought the poor guys would be fed up after dealing with all our pets… pestering them, they'll be anyone's for a good scratch 😂. The unit they've fitted is neat and well placed and we feel confident after having how it works explained that we'll have no more issues with black mould and condensation. We paid a much

I found David and the guys very professional from the initial quote to them finishing the job, in places the damp course was from floor to ceiling and required total replastering. All the work has been done to a high standard and I would definitely recommend them

Excellent job from start to finish. David is very knowledgeable on causes of mould and their effect on health. The installation was quick and clean and he gave after sale advice as well.
