Woodworm Treatment - excellent service
Customer Service
CavityTech responded very quickly in coming out to assess our woodworm issue. Good, honest advice and recommendation for treatment. Competitive quote. Punctual service. Clean, tidy and professional. Even a power cut didn't stop the treatment being applied as they carry a generator (also handy for plugging the kettle in to keep all happy!). We now have peace of mind our joists and floors are protected.

Installed additional air bricks. Replaced rotten timber wall plates with concrete ones. Installed 150mm shingle with 1200 gauge visqueen on top of existing concrete slab in floor void to eliminate damp surface. Replaced some wet rot affected timber joists.

Fantastically knowledgeable and honest surveyor
CavityTech's surveyor, Ray Thomson, came and gave us a thoroughly knowledgeable assessment of our damp problem and recommended a low-cost course of action, which did not involve his company. He is a mine of information and CavityTech should be proud to have him on board.
