What is penetrating damp? Penetrating damp is water entering a building horizontally through walls, roofs or external defects — unlike rising damp, it can appear at any height and worsens during rain. Common causes include cracked render, failed pointing, leaking gutters and porous brickwork. Treatment means repairing the defect and weatherproofing the wall.
Signs of penetrating damp in your home
Caught early, penetrating damp is far cheaper to fix. If you recognise any of these, it’s worth getting a local expert to take a look — our advice is free.
- Damp patches that grow in rain — isolated patches on walls or ceilings that darken during wet weather
- Water staining — brown rings or streaks on plaster, often high on the wall
- Blistering plaster — damaged, bubbling internal finishes near the leak
- Moss on external walls — green staining outside marking where water runs or sits
- Damp around windows — leaks tracking in around frames, sills and reveals
- Drips or wet patches in lofts — roof-level water finding its way inside
What causes penetrating damp?
Sussex's coastal weather is brutal on building fabric: driving rain off the Channel finds every crack in render, every failed mortar joint and every blocked gutter. Once the outer skin of a wall is breached, water soaks through to your internal finishes.
The most common culprits we find are cracked or blown render, perished pointing, leaking or overflowing gutters and downpipes, damaged roof coverings and flashings, and porous bricks on exposed elevations — all fixable, and far cheaper to repair early.
Not sure this matches what you’re seeing? Book a local damp survey and we’ll diagnose it properly — survey fees are discounted from any work you go ahead with.

Our surveyor inspects inside and out to pinpoint exactly where water is getting in — no guesswork, no unnecessary work.

We fix the actual cause: repointing, render repairs, gutter and downpipe fixes, flashing or sill repairs.
