Older homes across Leamington Spa and the wider Warwickshire area are increasingly suffering with penetrating damp especially solid wall properties that have been repaired with the wrong materials over the years.
At SD Roberts Plastering & Wall Insulation, we recently carried out a damp wall repair in Leamington Spa, where we stripped back a heavily damaged internal wall caused by long-term moisture ingress and failing plaster systems.
Common causes of penetrating damp in older homes:
✔ Cracked or damaged external render
✔ Blocked or leaking guttering
✔ High external ground levels
✔ Cement-based repairs trapping moisture
✔ Poor ventilation and condensation build-up
✔ Inappropriate internal plaster systems on solid walls
One of the biggest issues we see in older Warwickshire properties is the use of gypsum backing plaster on traditional solid walls.
Gypsum plasters are designed for modern cavity wall construction not breathable solid walls found in many period homes around Leamington Spa, Warwick, Kenilworth and surrounding areas. When gypsum is applied to damp masonry, it can:
❌ Trap moisture within the wall
❌ Accelerate plaster failure
❌ Cause blown plaster and salt contamination
❌ Increase mould growth risks
❌ Prevent the wall from naturally drying out
For older properties, using correct materials and understanding how moisture moves through traditional buildings is critical.
