Helpful with what we required as it was not straightforward and kept in touch with us the whole way through. In terms of price they were very competitive and installation was superb. We will certainly use them again and would highly recommend them to anyone.

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.

Windows installed, very happy with the service, nothing was too much trouble for Danni and her Team! Highly recommended business!! Thanks Danni x

Friendly and professional advice combined with great value. We had previously used a national window chain for our back windows and found GIS better value for our front windows. We also appreciated a fixed quote they gave us for the time we needed. The fitters worked hard and to time (in the rain) and the after service has been great.

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.

A very professional, yet personalised service, a great company to deal with overall. The surveyor was able to come up with an idea for the inward opening porch door I so wanted and the installers were quick, efficient and left the area clean and tidy after each installation. A great company and a local business too. Very pleased. Thank you GIS.

From quote to completion we had a great service. We found that GIS were much better than the national companies that we got quotes from. Danni was also able to offer advice about different windows to use and installation was completed on time. Overall I would highly recommend getting your double glazing done through GIS. Installation was great - they guys who came worked really hard and cleaned up any mess as they went along. We've seen our heating bill go down over the winter as the old double glazing was so bad
