Our passive fire protection services include fire-resistant walls, floors, door sets, and compartmentation systems. We install certified fire screens and maintain compliance with current building regulations. Our accredited team ensures buildings meet safety standards through specialist materials and construction techniques.
Roofing
We provide comprehensive roofing solutions including flat roofing systems, pitched tiling, lead work, and rooflight installations. Our services cover refurbishment, renewal, and emergency repairs using three-layer felt or single-ply membranes. The family-run business maintains traditional craftsmanship while adopting modern techniques.
Joinery
Our joinery division creates bespoke windows, doors, and staircases to exact specifications. The team produces both traditional and contemporary designs suitable for commercial and residential properties. All joinery work meets current building regulations and integrates with fire protection systems where required.

We specialise in fire compartmentation to prevent fire spread through buildings. Our solutions include installing fire-rated partitions, sealing service penetrations, and creating protected escape routes. This critical passive protection measure helps contain fires and smoke within designated zones.
