Services
Damp Treatment
We diagnose and resolve rising damp, penetrating damp, and condensation issues using British Standard-compliant methods. Our treatments include damp-proof course injection, waterproof barriers, and ventilation improvements. Each solution addresses root causes to prevent recurrence, ensuring structural integrity and habitable environments.
Tanking Systems
Our tanking systems create impermeable barriers against water ingress in basements and cellars. Using cementitious coatings and membranes, we transform damp spaces into usable areas. Solutions are tailored to structural conditions and intended usage, with options for drainage integration where required.
Timber Treatment
Specialist treatments for dry rot, wet rot, and insect infestations restore timber integrity. We employ fungicidal and insecticidal sprays, moisture control measures, and replacement of compromised timbers. All work prevents further decay while maintaining structural safety and compliance.
Cellar Treatments
We convert damp cellars into functional spaces through drainage systems, sump pump installations, and membrane linings. Our multi-stage process ensures water management, structural protection, and finished interiors suitable for storage or habitation.
Condensation Control
Targeted solutions address condensation-related mould growth through improved ventilation, thermal insulation, and surface treatments. We identify moisture sources and implement passive vents or mechanical systems to maintain dry, healthy environments.
