Services
Damp Surveys
Our comprehensive damp surveys identify hidden moisture issues using thermal imaging and specialist equipment. We assess rising damp, penetrating damp, and condensation to provide tailored treatment plans. Our surveys include detailed recommendations and cost-effective solutions for long-term property protection.
Rising Damp Treatment
We install damp-proof courses and treat existing damp using minimally invasive techniques. Our solutions address salt contamination and replastering to restore structural integrity. Treatments come with a 20-year guarantee to ensure lasting protection against moisture ingress.
Penetrating Damp Solutions
Our team diagnoses and repairs external water ingress through walls, roofs, or below-ground areas. We seal cracks, replace damaged materials, and apply weather-resistant coatings to prevent future moisture penetration while preserving architectural integrity.
Timber Treatment
We treat wet rot, dry rot, and woodworm infestations using specialist fungicides and replacement techniques. Our approach includes moisture control measures to prevent recurrence and maintain structural timber health.
Basement Waterproofing
Our cavity drainage systems and sump pump installations protect basements from groundwater ingress. We provide both interior and exterior waterproofing solutions to create dry, usable spaces with long-term moisture control.
