Their installation team was awesome! I have nothing but praise for their work. The office staff, not so much. We ordered the window replacement very early this year and they never called. I called several times and on the second call the same response was given. That was they were waiting on two Windows to arrive. After explaining that to them, things moved quicker.
I recommend this company as the windows are amazing, you just need to keep in touch with the office staff as they will not.
