We had our old tilt and open patio window which was not dealing properly and 'letting in a gale' replaced with a 3 panel bi-fold patio window. The removal and installation was completed with minimum of fuss and mess, and has made the living room so much warmer. The old windows was simply cut out, and removed from site, and the new built in situ and looks really good. We would certainly recommend both the company and the installers to anyone wanting new windows, etc.

We had the main windows replaced including two curved bays for a 1930s semi. They are very friendly and straightforward to deal with and helpful from the start. They gave very good advice on details of layouts, opening windows, and artwork, helping us to improve on our original ideas. They are easy to get in touch with and get back fairly quickly if it is necessary to leave a message. The work was completed tidily and they re-fitted curtain rails and blinds in the rooms that had them. The end result is impressive, with custom artwork on the front windows which goes well with the existing door and fits well with the design of the house. We have recommended them to friends who have been equally happy with the work. This was the third time we have used this company and have had no problems. On a previous occasion when a door needed a minor adjustment they happily came and sorted it out, so aftercare is good too in the unlikely event it is needed.

A friend recommended David Cannon Windows and we have not been disappointed. Courteous, professional workers who cleared up all the mess. We are awaiting our fifth window and will be using this firm to fit all our new windows. I previously had a quote from a very well known firm, who really tried the hard sell and would have been very expensive. This firm compares very well and I felt they were a lot more honest than the other firm.

This is the second time I have used David Cannon Windows and both times it’s been a painless experience, their fitters are professional courteous and first class , the cleanup up was that good I didn’t know they had been apart from the fantastic bifold window they fitted thank you all good old fashioned service

I cannot praise David Cannon and his team highly enough. This is the second time I have used them and once again high quality windows, professionally fitted and all round quality customer service! They have also fitted windows and doors for many of my friends with the same outcome, very pleased indeed. Many thanks to D Cannon Windows Ltd, keep up the good work!
