Why damp proofing matters
Damp can cause several issues in your property, including:
-
Peeling paint or bubbling wallpaper: Moisture behind surfaces causes coatings to lift, affecting appearance and requiring repair.
-
Discoloured or damaged plaster: Water penetration weakens plaster, leading to cracks, crumbling, or staining.
-
Musty smells and mould growth: Persistent damp encourages mould, which can affect air quality and health.
-
Cold or damp walls: Retained moisture lowers wall temperatures, making rooms feel uncomfortable and promoting condensation.
-
Warped skirting boards or flooring: Wood absorbs water, leading to distortion, gaps, and structural concerns.
-
Salt marks or staining on walls: Rising damp leaves salt deposits, damaging paintwork and plaster over time.
This approach not only clearly highlights the problems but also explains why each requires professional attention.
