I am so disappointed with this company. I had them replace a large window in my home and paid $420. Not 24 hours later the window (above a sliding door up high) had a huge crack down the entire pane of glass. I called them multiple times to replace it and after weeks of calling they informed me their work is not guaranteed and they won't replace the glass or refund our $420. So we're out of luck!! I have never received this lack of customer service and would never recommend Performance Glass to anyone.
