Everything was good. BUT, we were in a tight budget and really wanted black frames. The salesperson told us it was $1,000 more for black. So, we went with white. Neighbor down the street got windows told him I live the black. He told me he was quoited the same price for white and black.

We had three patio doors and two windows replaced. All went well except one patio door. It took five visits and nearly four months to finally get the problem corrected. Ultimately it was Darian and Damian that identified the problem and was able to fix the original problem. Darian has been the best to work with throughout.
