These guys seem ok for basic glass switch. Anything more complex, like entire window switch out and they are cowboys. They never respond to messages or show up to appointments. They do not honor their warranties. The windows in our apartment were under warranty, they wasted time, didn't show up to appointments until the warranty was up. One guy did show up and said that the terrible seals around the windows and the failure of the windows to latch close "wasn't a problem". Never heard from them again. I really don't trust the positive reviews. Not here and especially now on other sites. read more
