🏡 Why Are Older Homes More Prone to Damp?
Historic and older properties were often built with solid walls, lime plaster, and natural ventilation, which allowed moisture to pass through freely. However, modern renovations, blocked air bricks, and failed damp-proof courses can lead to serious damp problems.
Understanding the causes of damp in older homes is essential to finding the right solution.
🔍 Common Signs of Damp in Older Properties
✅ Peeling paint or wallpaper – Moisture behind walls causes bubbling and flaking.
✅ Musty smell – A strong, damp odour often indicates hidden moisture.
✅ Tide marks & staining – Brown or yellow marks on walls suggest water ingress.
✅ Mould growth – Excess humidity encourages mould, which thrives in damp conditions.
✅ Crumbling plaster – Salt deposits from rising damp can break down old plaster.
If you notice any of these signs, acting fast can prevent costly repairs.
💧 What Are the Main Causes of Damp in Older Homes?
1️⃣ Rising Damp – Caused by a missing or failed damp-proof course (DPC). Moisture travels up through walls, leaving visible tide marks.
✔️ Solution: Install a silicone-based damp-proof course and replaster with breathable materials.
2️⃣ Penetrating Damp – Occurs when water seeps in through cracks in brickwork, damaged pointing, or blocked gutters.
✔️ Solution: Repair brickwork, apply breathable waterproof coatings, and improve drainage.
3️⃣ Condensation – A common issue in homes with poor ventilation. Warm air hits cold surfaces, forming moisture.
✔️ Solution: Install Positive Input Ventilation (PIV) systems and improve airflow.
