Had double glazed windows and doors fitted September 2015.If we had known how bad they would be fitted or how terrible their customer service is, we would never have touched them. Should have gone with our instincts. I can't write all the problems we have had because there are just too many to list. We are still getting issues fixed with them now. One being our front door which has been replaced 6 times. Another being our bathroom window handle, which was scratched & dented by them. The man turned up this week to replace the handle, (which has taken 5 months) but he turned up with the wrong colour, even though I took a picture & sent it over to Linda.. To name a few of the issues we had: Cracked windows installed Wrong colour handles Different sized vents Wrong size windows Wrong design windows Scratched/damaged windows Windows Installed incorrectly, ie, could see day light through the frame. Basically, screwed in the wrong way & pushed the window out. Window seals outside, one side would have a massive gap & the other side no space. The list goes on and on. We have been told by Leekes the installation was not good. Even when we had more issues they sent out the original window fitter, which I denied him access. He is apparently the fittings manager now....
