Penetrating damp is a common issue in North Wales homes, particularly in older properties or those exposed to heavy rainfall and strong winds. Left untreated, it can lead to structural damage, mould growth, and higher heating costs. Understanding how to identify, prevent, and treat penetrating damp is key to protecting your home.
What is Penetrating Damp?
Unlike rising damp, which moves upward from the ground, penetrating damp occurs when moisture seeps in from external walls, roofs, or windows. It is usually caused by:
🔹 Damaged Brickwork or Render – Cracked masonry and worn-out pointing allow water to penetrate walls.
🔹 Blocked or Faulty Gutters – Overflowing gutters direct water onto walls, increasing moisture penetration.
🔹 Leaking Roofs & Chimneys – Water enters through gaps in tiles, flashing, or chimney stacks.
🔹 Porous Walls – Older stone or brick walls absorb moisture over time, especially in exposed coastal areas.
🔹 Bridging Issues – External ground levels too high, allowing moisture to bypass damp-proof courses (DPCs).

Signs of Penetrating Damp in Your Home
Look out for these warning signs of penetrating damp:
✅ Damp Patches on Walls & Ceilings – Often worsening after heavy rain.
✅ Peeling Paint or Blistering Plaster – Moisture pushes through walls, damaging finishes.
✅ Mould Growth & Musty Odours – Persistent damp encourages mould, which can impact health.
✅ Discoloured or Crumbling Brickwork – External walls showing white salt deposits or cracking.
✅ Cold, Damp Walls – Walls feeling damp to the touch even when the heating is on.
Ignoring these signs can lead to serious structural damage and higher heating bills, as damp walls lose heat faster.
