Services
Warm Roofs
The Guardian Warm Roof System is the biggest revelation to hit the home improvement market in the last ten years. You can now change your old conservatory roof for a new Guardian Roof and effectively turn your old conservatory into a new extension that can be used all year round. The complete changeover takes only three days with very minimal disruption to your household. The Roof System is designed to replace the existing glass or polycarb roof of a conservatory while retaining the original windows, doors, frames and walls. At the same time providing substantial energy cost savings.
Composite Doors
Choice of standard door colours and glass, triple glass for added performance, our triple glazed designs combine great aesthetics with high performance, offering improved sound and thermal insulating qualities.
An alternative to PVCu doors are composite doors which offer the same benefits of excellent security and low maintenance, but composite doors have the traditional look of a wooden door.
