I have a problem with a window they installed. Every time I called over a 2 wk period, they gave me a different excuse--they couldn't find my invoice; they couldn't find the install date (I dug thru my credit card bill & found the date); need manager approval but she wasn't in & would call me back (not); mgr was in a meeting and she would call me back (not). After receiving NO satisfaction, I drove to their shop. When I asked for the mgr, someone pointed to a blond woman on the phone but she said "HE'S on vacation"--first time I heard that excuse and first time I heard mgr was a man! When she finally got around to me, first she said I was improperly opening & closing the window, then said the problem was my frame was old, something they NEVER mentioned when they installed the new window. Their prices are cheap for a reason -- no after-install customer service. I live on a golf course & will need many future services, but never again from them.
