Whoops! Didn't mean to post that but I'll ask anyway. I want to get new uPVC windows all through our house. Many other houses in the street have had them installed, mostly by landlords for their student houses. But most of them have warped and look very cheap.
How can I make sure that when I have mine fitted they look and stay flat? I know I'll get a 10 year guarantee and all that, but I don't want to get a bad deal! I also know that cheaper windows may buckle sooner.
Any help appreciated!
