Penetrating damp occurs when water leaks through walls or ceilings, typically caused by structural issues such as defective roofing or faulty guttering. Unlike rising damp, which moves upwards, penetrating damp moves horizontally or downward through the structure, causing localized water damage.
How to Identify Penetrating Damp
Signs of penetrating damp include:
✔ Damp patches on walls, ceilings, or floors, often darkening when it rains.
✔ Mould growth on the surface of affected areas.
✔ Decaying plaster and timber within the damp zone.
✔ Foul or musty odours indicating moisture trapped within the walls.
✔ Damage to finishes, such as peeling paint or wallpaper.
Common Causes of Penetrating Damp
Penetrating damp is primarily caused by water ingress from external sources. The main causes include:
Leaking roofs or damaged roofing materials.
Faulty or blocked guttering and downpipes.
Cracks in exterior walls or window seals.
Damaged external brickwork or pointing.
