Services
Damp Treatment
Our damp treatment services address rising damp, penetrating damp, and condensation through specialist diagnostics and remedial solutions. Using advanced moisture analysis, we identify root causes and apply waterproof membranes, damp-proof courses, or ventilation systems tailored to property needs. All treatments include replastering with salt-inhibiting materials and come with insurance-backed guarantees for long-term protection.
Timber Treatment
Specialist timber treatments combat woodworm infestations and fungal decay in structural timbers. Our CSRT-qualified surveyors conduct thorough inspections to determine treatment requirements, applying boron-based preservatives or epoxy repairs to affected areas. We follow PCA standards for chemical application and provide detailed reports documenting intervention scope and future maintenance recommendations.
Basement Tanking
Basement tanking creates watertight underground spaces using cavity drain membranes or cementitious coatings. Our systems manage hydrostatic pressure through drainage channels and sump pumps, transforming damp cellars into habitable rooms. The process includes structural assessments, membrane installation, and plastering with breathable renders to meet building regulations for habitable spaces.
Wall Tie Replacement
We replace corroded cavity wall ties using stainless steel alternatives to restore structural integrity. Our surveyors use endoscopic inspections to assess tie condition, followed by controlled drilling and resin-anchored replacements. The process maintains wall stability while preventing further movement, with warranties covering material defects and workmanship standards.
Condensation Control
Our condensation control solutions combine ventilation improvements with thermal imaging diagnostics to address moisture accumulation. We install passive vents, mechanical extraction systems, and thermal linings to maintain optimal humidity levels. Treatments include anti-mould coatings and plaster repairs to eliminate existing damp stains and prevent recurrence in high-risk areas.
