"They did an awesome installation even with a blizzard. We offered to reschedule, but they said it was okay. Really outstanding job and clean up. There was a little delay from the salesman keeping us informed with the status of the permit and timing. Seemed to be because of busy holiday season. When we did talk, he was very helpful. We would use again. "
