Services
Damp Proofing
Our damp proofing solutions address rising and penetrating damp through membrane installation and chemical injection. Expert technicians identify moisture sources, treating walls and foundations to prevent structural damage. Services include basement waterproofing and wall tie replacement, ensuring long-term property protection while maintaining building integrity.
Condensation Treatment
Specialised condensation control tackles black spot mould and excess moisture. We install anti-condensation units and ventilation systems while addressing underlying causes. Surveys identify thermal bridging points, with treatments combining surface sterilisation and humidity regulation to prevent recurrence and improve indoor air quality.
Dry Rot Repair
Targeted dry rot eradication involves affected timber removal and chemical preservation. Our process includes moisture content analysis, spore eradication, and structural repairs using treated wood. We implement preventative measures against future infestations while restoring compromised building elements to full structural integrity.
Woodworm Eradication
Professional woodworm treatment combines chemical preservation with affected timber replacement. We conduct thorough inspections to identify infestation extent, applying insecticidal treatments to eliminate larvae and prevent reinfestation while preserving structural wood components.
Basement Waterproofing
Comprehensive basement waterproofing systems prevent water ingress through cavity drain membranes and tanking solutions. We install sump pump systems and drainage channels to manage hydrostatic pressure, transforming damp cellars into habitable spaces while maintaining structural durability.
