South Wales Valleys terraces are prone to rising damp in solid stone walls, with many built directly into hillsides creating ground moisture pressure. Bristol’s Georgian and Victorian properties in Clifton, Redland, and Bedminster have ageing damp-proof courses. Welsh weather means persistent moisture and penetrating damp through masonry is common. Cardiff Bay and dockside conversions can experience water ingress. Mining heritage properties often have settlement issues that allow moisture paths.
We do not apply a one-size-fits-all fix. We treat each job with care and respect and aim to do it right first time, everytime.
Recommendations are based on survey findings, property type and the most appropriate treatment method.
Damp proofing work is backed by a guarantee where applicable.

Noticed signs of damp, mould, or timber damage? Book a survey with your local DampMaster team today.
Get in TouchCommon signs of damp include tide marks or staining on walls, peeling paint or wallpaper, black mould, musty smells, and crumbling plaster or woodwork. You may also notice condensation on windows, cold or wet-feeling walls, or a general damp feeling in certain rooms, especially at ground level or in basements.
Damp can be caused by a range of issues, including rising damp from the ground, penetrating damp due to leaks or damaged masonry, condensation from excess moisture in the air, or even faulty gutters and drains. Our surveyors will assess your property to identify the exact cause and recommend the right solution.
Yes, especially if you’re seeing signs of damp or planning to buy a new property. A professional damp survey will help you understand the cause, severity, and best course of action. It’s the first step toward protecting your home (and your wallet) from long-term damage.
Costs can vary depending on the type of damp, the size of the affected area, and the treatment required. We carry out an initial damp survey so we can assess your property properly and provide a clear, fixed-price quote with no hidden fees.
Most treatments are completed within a few days, depending on the size of the job. We’ll always give you a clear timeline upfront, and we work hard to minimise disruption to your home.
In most cases, no. You can stay in your home while we carry out the work. If large areas need treatment or plastering, we’ll discuss this with you in advance so you can plan accordingly.
Yes, if plastering is part of the process, you’ll need to redecorate. We’ll leave your walls ready to paint or wallpaper once they’ve dried fully. We can also recommend trusted decorators in your area if needed.
