Services
Rising Damp Treatment
Rising damp treatment involves installing chemical damp-proof courses and repairing affected plaster to restore structural integrity. Our technicians use advanced diagnostic tools to identify moisture sources, ensuring long-term protection against salt contamination and wall decay. This service is ideal for properties with groundwater ingress through masonry.
Dry Rot Repair
Dry rot treatment removes infected timber, applies fungicidal solutions, and improves ventilation to prevent recurrence. We replace damaged wood with pressure-treated alternatives, addressing mycelium spread through masonry. This service safeguards structural stability for residential and commercial properties with fungal decay issues.
Woodworm Treatment
Woodworm treatment targets beetle larvae using targeted insecticides and monitoring systems. Our specialists identify species to tailor interventions, preserving structural timbers while preventing further tunneling damage. This service includes post-treatment assessments to ensure complete eradication of infestations.
Basement Conversions
Basement conversions incorporate drainage membranes and waterproofing systems to transform damp-prone spaces into functional areas. We address hydrostatic pressure and condensation risks, ensuring dry storage or living spaces with long-term moisture protection for subterranean structures.
Specialist Surveys
Specialist surveys provide detailed diagnostics of damp, rot, and structural issues using moisture testing and fungal analysis. Qualified surveyors deliver actionable reports with treatment recommendations, offering clarity on repair priorities for domestic and listed buildings.
