Penetrating damp is caused by water entering the building through an external defect or vulnerable area in the structure. DampMaster identifies the source of water ingress and recommends the most effective repair for long-term protection.

Water Damage
Penetrating damp can be linked to cracked render, defective pointing, damaged masonry, leaking gutters, roof defects or poor rainwater management.
It often becomes worse after heavy rain and may appear on higher sections of internal walls or ceilings.
You may notice localised damp patches, staining, bubbling paint, damaged plaster or repeated moisture issues after rainfall.
Unlike rising damp, the issue often appears in isolated areas rather than only at low level.
We inspect the affected area, assess surrounding building defects and trace how water is getting in.
Treatment recommendations may involve external repairs, roof-related work, improved rainwater handling or associated internal repair once the moisture source has been controlled.
Get In Touch
If you need expert Penetrating Damp advice or would like to book a survey, get in touch today and our specialists will respond quickly with the right solution.
We take a diagnosis-first approach, so the repair is tied to the real cause rather than the visible patch alone. We offer a full extensive review of all external defects that may need to be repaired (such as damaged rendering and leaking downpipes etc) to prevent the issue recurring.
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.
Common 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.
