Damp Proofing
Damp Proofing
Dampproofing protects buildings from moisture, preventing damage and health issues. It helps prevent problems like rising damp, penetrating damp, and condensation, keeping homes and businesses dry and safe. A robust damp proofing system adds value to your property and extends its life.
Wet & Dry Rot
Wet & Dry Rot
Wet and dry rot damage wooden structures, making them weak and unsafe. We remove affected wood, fix moisture problems, and treat timber with protective solutions. This stops rot from spreading and protects your home.
Wood Worm
Wood Worm
Woodworms can weaken timber, causing serious damage. We use specialist treatments, such as sprays and fumigation, to remove wood-boring insects and prevent further infestations, keeping your home’s structure strong and secure.
Basement Tanking
Basement Tanking
Basement tanking prevents water from leaking into underground spaces. We use waterproof coatings, drainage systems, and special membranes to keep basements dry, making them safe for storage, living space, or business use.
Cavity Wall Ties
Cavity Wall Ties Replacement
Old or broken cavity wall ties can make walls unstable. We replace them with strong, rust-proof ties to keep walls secure and prevent structural issues, helping maintain your home’s safety and value.
Condensation Control
Condensation Control
Condensation can lead to mould, damp smells, and health problems. Improving airflow, using dehumidifiers, and installing insulation can all help to prevent condensation by controlling moisture levels and keeping your home fresh and healthy.
Rising Damp Treatment
Rising Damp Treatment
Rising damp happens when water from the ground moves up through walls, causing damage. We stop this by installing damp-proof courses, using special creams, and improving drainage. Our treatments protect your home from mould, peeling paint, and weakening walls.
Penetrating Damp Treatment
Penetrating Damp Treatment
Penetrating damp occurs when rainwater leaks through walls due to damaged brickwork, roofs, or gutters. We fix this by repairing surfaces, sealing cracks, and applying waterproof coatings. These solutions keep your home warm, dry, and free from moisture damage.
Property Surveys
Property Surveys
Our expert property surveys identify damp, rot, and hidden structural issues. We provide clear, actionable advice on repairs and maintenance, helping homeowners, buyers, and landlords make informed decisions.

Frequently Asked
Questions
Got any questions, just ask!
HOW DOES DAMP PROOFING WORK?
Dampproofing prevents moisture ingress. Chemical injections create a water-repellent barrier to prevent rising dampness. For subfloors, damp-proof membranes block moisture transfer. We specialise in identifying the causes of these problems and implementing effective treatments. This includes drilling and injecting damp-proof creams or laying membranes.
HOW LONG SHOULD YOU WAIT TO DECORATE AFTER DAMP PROOFING?
After DPC installation and replastering, thorough drying is crucial. For wallpaper, wait up to 12 months. For water-permeable emulsion, 4-8 weeks is usually sufficient after visible damp signs disappear. Wall thickness also affects drying time. If in doubt, feel free to ask us for advice.
HOW MUCH DOES DAMP PROOFING COST?
The cost of damp proofing depends on the size of the property, the type of damp (rising damp, penetrating damp, condensation), and the extent of the damage. Contact us today to discuss your damp problem and arrange a survey, during which we will provide a personalised quote.
HOW TO DAMP PROOF A WALL?
Damp wall treatment depends on the cause:
- Rising Damp involves installing a new damp proof course (DPC) or injecting a chemical DPC.
- Penetrating Damp requires addressing the source of water ingress, such as repairing damaged roofing, gutters or brickwork and possibly applying a waterproof coating.
- Condensation involves improving ventilation, using dehumidifiers, and potentially applying anti-mould paint.
WHAT IS A DAMP PROOF COURSE?
A damp proof course (DPC) is a horizontal barrier in a wall designed to prevent moisture from rising through capillary action. Traditionally, it was made of slate or bitumen, but modern DPCs often use plastic or chemical injections.
HOW LONG DOES A DAMP PROOF COURSE LAST?
A properly installed traditional DPC made of slate or bitumen can last the lifetime of the building. Chemical DPCs typically have a lifespan of 20-30 years, and damp-proof membranes can also last the lifetime of the building, provided they are not damaged.
