Damp Repair & Proofing
Our comprehensive damp proofing solutions address rising damp, penetrating damp, and condensation issues through advanced diagnostic techniques and industry-approved treatments. We employ moisture meters, thermal imaging, and borescope cameras to identify root causes before implementing tailored remediation strategies. Treatments include chemical damp proof course injections, salt neutralisation, and waterproof renders, all backed by a 30-year guarantee. The process removes existing damp, prevents recurrence, and restores structural integrity while maintaining habitability during works.
Basement Tanking
Specialist basement waterproofing creates habitable spaces by preventing water ingress through cavity drainage membranes and cementitious tanking systems. Our solutions incorporate sump pumps, ventilation management, and multi-coat renders to create watertight environments. We address London's unique geological challenges with both barrier and water management systems, transforming damp basements into functional living or storage areas. All installations carry our standard 30-year watertight guarantee.
Condensation Solutions
Targeted condensation control combines diagnostic humidity testing with ventilation optimisation and structural modifications. We identify moisture sources through thermal imaging and humidity monitoring before implementing solutions like condensation control units and improved ventilation pathways. Our approach eliminates black mould growth, improves indoor air quality, and prevents structural damage while maintaining aesthetic integrity during treatment.
Penetrating Damp Treatment
Specialist treatment for water ingress through external building defects involves crack repairs, pointing restoration, and protective coatings. We use tanking liquids and cement renders to create waterproof barriers while addressing underlying causes like faulty guttering or damaged masonry. The process prevents structural decay, eliminates damp patches, and restores wall integrity through systematic diagnosis and remediation.
Rising Damp Treatment
Scientific rising damp solutions combine chemical damp proof course injections with plaster replacement and salt neutralisation. We address compromised damp proof courses through pressure-injected silicone treatments and remedial plastering systems. The process stops moisture migration, prevents decorative damage, and restores wall surfaces using breathable materials that maintain structural health and appearance.
Questions
What causes rising damp in London properties?
Rising damp occurs when groundwater travels through porous brickwork and masonry. Older properties often lack effective damp proof courses, while modern buildings may experience failure of existing barriers due to structural movement or material degradation.
How long does a damp survey take?
Survey duration varies with property size but typically takes 3-4 hours for standard homes. Advanced diagnostics like thermal imaging and drone inspections ensure thorough assessment without unnecessary delays.
Do you offer guarantees on damp treatments?
All treatments carry a 30-year watertight guarantee. We also provide a 10-year insurance-backed warranty for added assurance against future damp recurrence.
Can condensation cause structural damage?
Prolonged condensation leads to timber decay, plaster deterioration, and mould growth. Our solutions combine ventilation improvements with structural modifications to prevent long-term damage and health risks.
What areas do you cover?
We operate across London and the M25 corridor, serving central London boroughs through to outer areas like Wimbledon, Stratford, and Finchley with specialist damp solutions.
How quickly can emergency repairs be completed?
Emergency damp repairs start within 24 hours of contact. Our rapid response team addresses urgent water ingress issues while planning permanent solutions to prevent recurrence.
