Services
Damp Proofing
Our damp proofing service identifies and treats rising damp, penetrating damp and condensation issues in residential and commercial properties. We use proven chemical damp courses and membrane systems that are guaranteed for up to 20 years. Clients receive a free survey, transparent quotation and a tailored solution that protects property value and prevents future damage.
Basement Tanking
Our basement tanking service applies internal cavity membrane systems to create a waterproof barrier below ground level. It is suitable for both new and existing basements in homes and commercial buildings across London and the South East. The installation comes with a guarantee of up to 10 years, ensuring long-term protection against water ingress and structural damp.
Structural Waterproofing
Our structural waterproofing service protects foundations, walls and floors from water penetration using specialist coatings and membranes. We apply these systems to residential and commercial properties where ground water or high moisture levels threaten building integrity. All works are guaranteed for up to 10 years and are recognised by mortgage lenders as proof of effective waterproofing.
Woodworm Treatment
Our woodworm treatment service eradicates infestations in timber structures using targeted insecticidal sprays and heat treatments. We survey timbers, identify active beetle activity and replace severely damaged sections where necessary. Treatment carries a guarantee that is accepted by mortgage lenders, providing long-term protection for joists, flooring and roof timbers.
Condensation Control
Our condensation control service improves ventilation and installs humidity-sensing fans to reduce indoor moisture levels. We target properties suffering from mould growth, musty odours and water staining on walls and ceilings. The solution prevents condensation-related damp, protects decor and is backed by our standard workmanship guarantee.
