Services
Basement Tanking
Our basement tanking systems create watertight envelopes for subterranean structures using advanced cementitious coatings and liquid membranes. Applied directly to substrates with thickness under 5mm, these solutions eliminate need for supporting walls while maintaining structural integrity against hydrostatic pressure. Specialists handle both positive and negative pressure applications, ensuring continuity at wall/floor junctions through fillet sealing techniques to prevent water ingress in London's variable ground conditions.
Rising Damp Treatment
Chemical damp proof course injection addresses capillary moisture migration through porous masonry using low-hazard formulations. Our surveyors identify hidden causes including defective pointing, bridged DPCs, and structural defects before implementing remedial treatments. Services include plaster replacement, timber preservation, and ventilation improvements to prevent recurrence of damp stains and structural decay in historic and modern London properties.
Condensation Control
Targeted condensation management combines diagnostic moisture analysis with installation of extractor fans, heat recovery units, and passive ventilation systems. We address modern construction challenges like reduced natural airflow through double glazing and central heating systems, implementing tailored solutions to prevent mould growth and maintain indoor air quality across residential and commercial premises in London's humid climate.
Timber Treatment
Specialist timber remediation addresses dry rot, wet rot, and woodworm infestations through chemical preservation and structural replacement. Our approach includes moisture source elimination, affected timber removal, and application of boron-based treatments to protect load-bearing elements and joinery from fungal decay and insect damage in both historic and contemporary buildings.
Structural Repairs
Comprehensive structural remediation addresses water-induced damage to foundations, walls, and masonry. Services include crack injection, render replacement, and cavity drainage integration to restore structural integrity. Our surveyors identify construction defects contributing to damp ingress, implementing repairs that comply with building regulations while preserving architectural character in London's diverse building stock.
Questions
What areas do you cover for damp proofing services?
We operate across London SW, SE, W, Central areas plus Kent, Surrey and surrounding Home Counties.
How do you diagnose rising damp versus condensation?
Our surveyors use moisture meters, thermal imaging and visual inspection of damp patterns to identify causes.
Can basement tanking be done without structural modifications?
Yes, our thin-section tanking systems require no supporting walls, preserving internal space.
Do you provide guarantees for damp treatments?
All remedial works come with written warranties covering materials and workmanship.
How quickly can treatments be completed?
Most residential projects finish within 3-5 working days depending on property size.
Are your damp proofing chemicals safe for homes?
We use water-based, low-hazard formulations approved for residential environments.
