Services
Woodworm Treatment
Our woodworm treatment addresses infestations in structural timbers using environmentally friendly chemicals. We identify beetle species and apply pressure spraying, Boron gels, or rods to eliminate larvae. Treatments include long-term penetration solutions to prevent recurrence, protecting floor joists, roof timbers, and staircases across domestic and historic properties.
Damp Proofing
Damp proofing solutions tackle rising damp through chemical injection systems using silicone or stearate-based products. Our surveys identify causes and recommend replastering with Wykamol Renovating Plaster. We address hygroscopic salts and provide external brickwork protection, restoring properties to safe, dry conditions with minimum disruption.
Structural Stabilisation
Structural stabilisation employs stainless steel helical bars and lateral restraints to repair cracks and bulges. Our non-disruptive solutions redistribute tensile loads while accommodating natural movement, ensuring long-term stability for traditional buildings and modern structures without extensive reconstruction.
Wall Tie Replacement
Wall tie replacement addresses corrosion in buildings pre-1981 using mechanical, resin, or combination ties. We remove or isolate corroded ties, install stainless steel replacements, and match existing mortar. Services include lateral restraints and helical products to prevent structural collapse from wall tie failure.
Fungal Decay
Fungal decay treatments combat dry and wet rot through spore eradication and chemical fungicidal applications. We remove affected timber, treat masonry, and apply pressure-injected solutions. Replacement timber receives pre-treatment, with ventilation improvements ensuring long-term protection against moisture-related fungal attacks.
