Services
Damp Proofing
Our specialist damp proofing service addresses rising damp and penetrating damp through comprehensive surveys and targeted remedial treatments. Using advanced diagnostic tools, we identify moisture sources and implement chemical damp proof courses, wall plaster replacement, and ventilation improvements. Treatments follow British Standards and include guarantees, ensuring long-term protection while maintaining structural integrity for residential and commercial properties.
Basement Tanking
We provide structural waterproofing solutions for basements and underground spaces using cementitious tanking systems. Our method creates a continuous waterproof barrier that prevents water ingress while allowing structural movement. Services include substrate preparation, multi-coat waterproof coatings, and drainage solutions, ensuring habitable spaces meet building regulations and remain dry under hydrostatic pressure.
Dry Rot Treatment
Our dry rot specialists identify and eliminate fungal outbreaks through moisture source eradication, affected timber removal, and chemical preservation. We replace damaged timbers with pre-treated materials and implement ventilation improvements to prevent recurrence, restoring structural integrity while maintaining compliance with conservation standards for historic properties.
Woodworm Treatment
We treat wood-boring beetle infestations through targeted insecticide applications and affected timber replacement. Our approach includes identifying beetle species, assessing structural impact, and implementing preventative treatments. For severe cases, we reinforce weakened structures with steel supports or replacement timbers treated to BS 8417 standards.
Commercial Damp Surveys
Our detailed commercial surveys assess large-scale damp issues in industrial and retail properties. Using non-invasive testing methods, we produce comprehensive reports with photographic evidence, moisture readings, and prioritised remediation plans. Services include warranty assessments, insurance claims support, and compliance documentation for property transactions.
