Services
Damp Proofing
Our damp proofing solutions address rising damp and moisture ingress using British Standard 6576-compliant methods. We install physical and chemical damp-proof courses to protect property integrity. Customers benefit from long-term prevention of structural damage and mould growth.
Timber Treatment
We eradicate dry rot, wet rot, and woodworm infestations using industry-approved treatments. Our methods restore timber strength while preventing recurrence. This service ensures compliance with property care standards and maintains structural safety.
Wall Tie Replacement
Our wall tie replacement service reinstates structural stability in cavity walls affected by corrosion or failure. We use durable stainless-steel ties to meet building regulations. This prevents wall movement and ensures long-term building integrity.
Basement Waterproofing
We provide basement waterproofing using tanking membranes and cementitious coatings to prevent water ingress. Our solutions comply with British standards, transforming damp basements into usable, dry spaces for residential or commercial use.
Condensation Control
Our condensation control measures include installing ventilation systems and thermal insulation to reduce moisture buildup. This prevents mould growth and improves indoor air quality, particularly in poorly ventilated properties.
