Testimonials

Their very approachable nature, professionalism and knowledge make GIS a pleasure to work with. Nothing is ever too much, and they are always available by phone. The windows are of a high standard and I would never hesitate in recommending them.

Sibel Di Biasio

We recently used GIS to replace nearly all our windows and front door. Not only was the GIS quote the cheapest but we were also given an idea of the quote then and there which no other company were able to do. The service provided throughout was first rate. Fitting was fast and professionally undertaken and we are very happy with the final product.
