We previously used them to replace all our windows and our front door/storm door and trusted them with this big project as well. Their work is impeccable. Bob was great to work with and fast when installing the garage doors - he checked in with us every step of the way, and the doors work and look great. The garage doors have black handles and tinted windows and look amazing - now the interior of the garage is much brighter and it makes it seem bigger. The entire front of our house looks new and modernized now.

I was…read moreignored, phone calls not returned, I called weekly, and was finally told our business was put on the back burner. Finally the installation was done in April. Unprofessional, sloppy, had to be redone twice. They told us they were coming to hang the mirrors, didn't show, didn't bother to call.....rescheduled business appointments to have them install mirrors, when they did not show......cost our company hundreds of dollars. Very disappointed. Mirrors are great when finally here and installed but very unprofessional people to work with from my point of view.

He said would be in about 2 weeks. 6 weeks later no phone call..nothing. My husband called said it wasn't in yet. We waited another 3 weeks. I called and the lady says "oh that's been here for weeks". Lol. What??? Um ok. So I talk to Dave a week later because he never called me back. Tells me that he has workers out sick and they need 3 men for the job. Um if my window has been in for weeks why hasn't someone called??? No answer of course. Sooooo he tells me he'll call me when he can get someone out to install it. 2 weeks later NO PHONE CALL. my husband calls AGAIN and DAVE of course is not available. So Finally he calls my husband today and is soooo rude I can't even call him what I want. Put it this way Dave says "so do you want the window or not". Lol. Glad we never gave them a dime. This place is a joke. DONT BUY FROM THEM!!!
