We had a few quotes but the gentleman we saw from Top Glass Renovations came up with a good deal to upgrade our windows and also included composite doors for the front and side of our house.
The windows look good, we have no drafts any more, and the doors are much stronger and more secure than the ones that they removed. they took all of the old windows and doors away to be recycled.
We have recommended Top Glass Renovations to friends already, and will ask them for a further quote when our extension is nearing completion.
