Damp Proofing in Chiswick
Rising damp, penetrating moisture and condensation can create similar symptoms but require different solutions. We investigate the source before recommending treatment, helping you avoid ineffective work and resolve the condition that is damaging your property. Where water is getting in, we also waterproof basements, external walls and flat roofs, choosing a system suited to the structure and the route the moisture is taking. We cover Chiswick (W4) and the nearby London area.

Damp Proofing — Chiswick
Damp Proofing in Chiswick
Effective damp and water treatment begins with the correct diagnosis. We identify how moisture is entering or forming, address the underlying cause, waterproof where the building needs it, and specify any remedial plastering or ventilation required. We work across Chiswick and the surrounding London area, including Hammersmith, Chiswick High Road, Bedford Park and Westbourne Park, with free site visits and fixed-price written quotes.
- Assessment of rising damp, penetrating damp and condensation
- Installation or injection of a damp-proof course where appropriate
- Removal and replacement of contaminated plaster systems
- Repairs to causes of water penetration, including pointing and guttering
- Tanking for basements and cellars, and external wall waterproofing
- Waterproofing systems for flat roofs and below-ground structures
- Practical ventilation guidance to reduce condensation
What affects the price: Costs depend on the diagnosed damp type or water ingress, the affected area, the treatment or waterproofing system needed and the extent of replastering. Your written quote will distinguish the underlying repair from the internal remedial work and itemise both.
