Services
Dry Rot Treatment
Our dry rot treatment involves removing infected materials, eliminating moisture sources, and applying fungicides. We replace damaged timbers with pre-treated sections and renew wall plaster under specialist supervision. This process ensures structural integrity and prevents recurrence, backed by a 10-year guarantee.
Woodworm Treatment
We identify active woodworm infestations through hole patterns and seasonal activity checks. Treatments include preservative applications or deep-paste injections, depending on severity. Post-treatment guarantees last up to 30 years, ensuring long-term timber protection for residential and commercial properties.
Rising Damp Treatment
Our rising damp solutions involve low-pressure chemical damp-proof course injection and replastering with waterproof render. We address bridging issues caused by ground levels or plaster defects. Treatments include 10- or 30-year guarantees, ensuring lasting protection against moisture intrusion in walls.
Timber Preservation
We offer comprehensive timber preservation through chemical treatments and structural repairs. Our methods prevent decay from moisture exposure or insect attack, extending the lifespan of wooden elements in historic and modern buildings while maintaining compliance with industry standards.
Damp Proofing
Our damp proofing services include identifying rising damp causes, installing chemical damp courses, and replacing salt-contaminated plaster. We follow PCA codes of practice, ensuring effective moisture barriers that protect building integrity and meet lender requirements for property transactions.
