Benefits of damp proofing
- Protects Structural Integrity
Damp can weaken walls, plaster, and timber. Our treatments preserve the strength and longevity of your building.
- Prevents Mould and Health Risks
Damp environments promote mould and mildew, which can trigger respiratory issues. Damp proofing helps maintain a healthier indoor climate.
- Increases Property Value
A dry, well-maintained home is more attractive to buyers and surveyors. Damp proofing is a smart investment in your property.
- Energy Efficiency Boost
Damp walls lose heat faster. Our exterior water repellent helps improve insulation and reduces heating bills.
- Long-Lasting Results
We use industry-standard materials and techniques that provide up to 20 years of guaranteed protection.
- Tailored to Your Property
Every building is different. We offer personalised solutions based on thorough inspections and the unique needs of your home or business.
What is Damp and Why Does It Matter?
Damp isn’t just a cosmetic issue – it’s a serious threat to the structure and comfort of your home or business. Left untreated, damp can lead to crumbling plaster, timber decay, unsightly staining, mould growth, and costly repairs.
At West Wales Property Maintenance, we specialize in identifying the source of damp and delivering long-lasting, BS 6576:2005 compliant damp proofing treatments that restore your property’s health and value.
Rising Damp Treatment
Rising damp is caused by ground moisture being drawn up through porous bricks and mortar – a process called capillary action. It usually affects older buildings that were built without a damp-proof course, or where the original DPC has deteriorated or been bridged.
Signs of rising damp include:
- Damp patches and tide marks on lower walls
- Peeling paint and wallpaper
- Crumbling plaster
- White, powdery salts on the surface
Our solution: We remove salt-contaminated plaster and inject a chemical damp proof course (DPC) into the base of the wall. This creates a new waterproof barrier to stop moisture from rising. We then replaster the area using specialised materials to prevent future problems.
We use:
- DPC Injection Cream – A silane/siloxane-based emulsion that deeply penetrates masonry for long-lasting protection.
- Potassium Methyl Siliconate Fluid – A highly effective formula that creates a reliable moisture barrier when properly applied and diluted.
Penetrating Damp Treatment
Penetrating damp occurs when rainwater and external moisture pass through walls made of brick, stone, concrete, or render. This type of damp often results from:
- Damaged pointing or brickwork
- Defective gutters or downpipes
- Cracks in render or roofing
- Porous, untreated exterior surfaces
If left untreated, penetrating damp can lead to wet rot, dry rot, and even structural failure.
Our solution: We locate the moisture entry point, carry out any necessary repairs, and apply a high-performance external water repellent to all exposed masonry. This treatment:
- Stops water penetration
- Reduces heat loss
- Prevents lichen, algae, and dirt build-up
- Allows the walls to "breathe" naturally
