    I had two bespoke built, arched double glazed windows fitted. They were designed, and manufactured to a high standard ensuring that the installation process went through without a hitch. In a short time, they were gone leaving no mess behind.

    We used Fortress to replace a large patio door and three windows. We found them very professional and were extremely pleased with the work from start to finish and would not hesitate in using them for further work in the future.

    This is the 3rd occasion we have engaged Fortress UPVC for our replacement needs and again our installation experience from Dave Martin, proprietor, has been outstanding. An extremely professional and considerate approach to his work means the final result is always superb and his latest visit is no different. Extremely happy with Dave's work and we are very happy to recommend him to others.

    10Verified Review

    We have used Fortress on a couple of occasions now, for replacement UPVC windows and also a glass conservatory roof. I have found the workmanship to be of the upmost quality, and they are very friendly and polite and do a great job of tidying up behind themselves and removing all of the rubbish. I will certainly use them in the future and would highly recommend them to others
