I purchased 10 windows from AM Group of companies on April 29 2018. They were installed between August 16 & 27. Their contract indicates a manufacturer lifetime warranty & an AM Window & Door workmanship warranty of 10 years. The window in the main floor bedroom is an awning window. From the beginning I noticed it pulled in tighter on the right side than the left. When I mentioned it to the installer they said that wasn’t an issue. Recently while cleaning the window I had the screen off & for the first time I noticed the reason the one side didn’t pull in tight is because the 2 parts of the mechanism that pulls it tight do not line up. I got a carpenters square & put it against the window frame & found that the window was installed out of square forcing the mechanism out of alignment. I called AM that day & within a couple days they sent a technician. That was early to mid October. He looked at the window, took several pictures & said he would put in for a warranty replacement. While he was here I asked him to look at the bay window in the living room because it is difficult to operate. I told him the window was too large for the opening so the installer split the studs on either side to make the opening wider. At this point the technician got quiet & made no commitment. This window has 3 panels - 2 casements with a fixed window between. The 2 casement windows are now difficult to close & I am somewhat concerned the structural integrity has been compromised & may have settled causing pressure on the window. Since the technician was here I have called the office 3 to 5 times to find out the status & what they were going to do to rectify the issue. Each time I called the person I spoke to said she would contact the tec & have him call me back. To this date no-one has called back.
