Services
Damp Proofing
Our damp proofing specialists identify and eliminate rising damp through chemical damp course installation and re-plastering. We conduct comprehensive surveys to determine moisture sources, implementing tailored solutions that include wall ventilation improvements and salt neutralisation. With 30 years' experience and a 20-30 year guarantee, we restore properties to dry, habitable conditions using environmentally friendly materials that protect both buildings and occupants.
Woodworm Treatment
We eradicate wood-boring beetle infestations using heat, freeze, and chemical treatments tailored to affected timber structures. Our surveyors identify active infestations through tell-tale signs like flight holes and frass deposits, then implement targeted interventions to preserve structural integrity. We offer pre-purchase woodworm surveys and restoration services for floorboards, beams, and furniture across domestic properties in South Wales.
Wet and Dry Rot
Our specialists diagnose and treat timber decay caused by excess moisture, distinguishing between localized wet rot and structural dry rot. We remove affected materials, implement moisture control measures, and apply protective treatments to prevent recurrence. With expertise in identifying mycelium growth and fruiting bodies, we restore compromised structures while addressing underlying ventilation and drainage issues to ensure long-term property health.
Tanking
We apply liquid waterproofing membranes to basement and cellar walls, creating impermeable barriers against ground moisture. Our tanking solutions include cavity drain systems and condensation control measures that maintain structural integrity while allowing walls to breathe. Serving properties within 50 miles of Swansea, we provide free estimates for basement conversions and structural waterproofing projects requiring BS8102-compliant protection.
Plastering
Our skilled plasterers deliver both repair work and full-scale re-plastering projects using specialist materials like Dri-Coat and Thistle. We prepare surfaces with precise undercoat mixes before applying decorative finishes, ensuring durability and aesthetic quality. From small repairs to complete property re-plastering after damp treatment, we maintain meticulous attention to detail while using breathable materials compatible with waterproofing systems.
