Services
Damp Treatment
Our comprehensive damp treatment services address rising damp, penetrating damp, and condensation issues affecting properties. Using advanced chemical damp proofing methods, we install impermeable barriers to prevent moisture migration through walls. This process protects structural integrity while improving indoor air quality by eliminating mould growth. Each treatment includes a detailed moisture assessment and comes with a long-term guarantee.
Woodworm Treatment
Specialist woodworm eradication involves identifying infestation extent and applying targeted biocidal treatments to eliminate active beetle colonies. We use environmentally safe chemicals that penetrate timber to destroy larvae and prevent reinfestation. The process includes structural assessment to identify weakened areas requiring reinforcement or replacement, ensuring complete pest elimination and property safety.
Basement Waterproofing
Our basement waterproofing solutions create watertight environments using tanking membranes and drainage systems. We apply cementitious coatings to internal walls and floors while installing perimeter drainage channels to redirect groundwater. This comprehensive approach transforms damp basements into usable living or storage spaces while protecting against future water ingress and structural damage.
Wall Tie Replacements
We replace corroded cavity wall ties with durable stainless steel alternatives to restore structural stability. The process involves removing failed ties, cleaning masonry cavities, and installing mechanical ties that meet current building regulations. This critical maintenance prevents wall movement and ensures long-term structural integrity for properties in coastal and high-wind areas.
Dry and Wet Rot
Our rot treatment specialists identify and eliminate both dry and wet rot infestations through targeted fungicidal applications. We remove affected timber, treat surrounding areas to prevent spread, and replace damaged structural components with pressure-treated alternatives. The process includes moisture control measures to address underlying causes and prevent recurrence of fungal decay.
