I had a $2600 window put in back in June. Right away I noticed it didn't lock correctly (SAFETY ISSUE!) I thought maybe it needed to "settle in place"-but no. I contacted them. Took a week or 2 to get someone out to fix it, only to be told in AUGUST that I need a new sash. It's now NOVEMBER and it still is not fixed. I'm in Minnesota...it's getting cold here. Those a@@es think its ok to have a huge gapping hole from an open window when they eventually get around to replace it in winter here. All I get is a run around and lies from one customer service or manager jerk to another. They have my money, I still don't have a working window!
