Prevent further damage to your property with damp proofing
With the many causes of dampness and possible remedies, it’s essential you get the best advice from specialists to get the right diagnosis. Damp proofing and remedial work is only effective when you know exactly what’s causing the damp problem and to what extent.
Whether you need to remedy a damp problem or convert a basement into a dry usable space, our PCA approved damp proofing specialists will find the cause with a damp survey, and carry out the essential work needed to make your property dry and comfortable again.
The types of damp we treat
Damp patches can look the same on the wall, but the causes and treatments are completely different. Getting the diagnosis right is the most important part of any damp proofing job, which is why every job starts with a damp survey rather than a quote.
Rising damp
Moisture drawn up from the ground through a failed, bridged or missing damp proof course. Look for tide marks up to around a metre, salt bloom and damp skirtings. Treated with a chemical DPC injection and salt-retardant re-plastering. See a rising damp case study.
Penetrating damp
Water getting in through the structure, at any height and often worse after heavy rain. Common causes are eroded pointing, defective gutters and blown render. We fix the defect first with pointing and render repairs, then make good inside.
Condensation and mould
Moisture produced inside the home that the building cannot get rid of, causing black mould on walls and window reveals. Resolved with better ventilation, such as extractor fans or a PIV unit, and targeted mould treatment. Condensation control.
Cellars and basements
Below-ground rooms need a different approach. We use cellar tanking and cavity drainage membranes, with sump and pump systems where water needs to be removed. Basement waterproofing.
Wet rot, dry rot and woodworm
Damp often leads to timber decay. We treat wet rot, dry rot and woodworm in joists and floor timbers, and put right the damp that caused it. Wet and dry rot treatment.
Not sure which you have?
Our guide to condensation vs rising damp explains the warning signs. For a definite answer, a damp survey by a CSRT qualified surveyor will identify the cause and the right treatment. Book a damp survey.
