We’ve noticed damp under the back window wall in our house on Bedale Avenue, Billingham. There are signs of water ingress, and the wallpaper behind the wall shows rising damp just above the skirting board. We’re concerned this could get worse if not addressed soon and would like advice on damp proofing.

Resolving Water Ingress and Rising Damp in Billingham

Identifying the Cause of Damp Under the Window Wall

Damp issues like this are common in older properties or homes with compromised damp proofing barriers. The problem in Paul’s home on Bedale Avenue is likely due to water ingress from the outside, possibly through the window frame or a failed damp proof course (DPC). Rising damp occurs when moisture from the ground travels up through the walls, often stopped by a DPC. When this barrier is damaged or missing, signs of damp such as peeling wallpaper and discolouration above the skirting board can appear.

Steps to Fix Rising Damp and Water Ingress

1. **Assessment**: A thorough inspection of the external wall, window frame, and surrounding area is essential. Cracks in the masonry or gaps in window seals could be sources of ingress. 2. **Repair and Sealing**: Fixing the window seals and repointing brickwork can stop water from penetrating. Any damaged mortar should be replaced with a waterproof mixture. 3. **Damp Proofing**: Injecting a chemical DPC or installing a physical barrier to prevent ground moisture from rising. 4. **Internal Repairs**: Removing affected plaster, treating the area with a damp-resistant solution, and replastering with a salt-retardant plaster. 5. **Ventilation**: Ensuring good airflow reduces moisture buildup inside the property.

Why Address Damp Issues Quickly?

If not tackled promptly, rising damp can lead to structural issues and encourage mould growth, which poses health risks. Fixing damp problems also protects the property’s value and ensures a more comfortable living environment.
