What our customers say

Belvedere windows came recommended, they were polite and professional in all aspects of their work, I would highly recommend them to anyone.

Andrew Jackson in Wakefield

Luke Bower fitted windows and doors for us following having an extension added to our house. He came when asked to measure, and fitted the new Windows and doors as soon as possible. We have had no problems with any of his services and I would certainly recommend him to anyone in the future.

Joanne Sinclair in Mirfield

We would like to thank Belvedere windows and doors for their excellent service at a very reasonable price, not to mention the excellent service from the design and quantity team that came out and measured our windows and doors up, a very well presented team and very professional service, would definitely recommend.
