I purchased Comfort Line windows for my entire house through a dealer/installer. The installation occurred over several months due to the fact that a number of the windows were of extremely poor quality... cracked sills, window sashes longer on one side than the other, major scratches in the window panes, cracks and breaks in a couple frames that were obviously doctored up to hide the damage. It seems the company doesn't take quality control seriously.
I had to wait several months before getting replacements for all the bad units we had to send back. Then, one of the windows they sent as a replacement came in totally out of square and couldn't even be installed in the opening for the window! Instead of rushing to correct a so obvious problem, they took their good old time replacing this window.
I had to wait yet another couple of months. So, I get the 3rd replacement for the same window space -- which is a large window with 4 double hung sahses -- and find that this too is made poorly; i.e., the bottom right of the inside frame is noticeably higher than the left. ONLY because this part of the window is hidden by my couch will I not bother to get a replacement for this, since their response is not at all customer-oriented, and I do not care to deal with them again!
