I built a metal building and Mountain Fox Garage Doors installed a 16' door and 8' door. He recommended I get a door that went straight up the wall, which I did and I was very happy with that. It works very well. They were prompt, on time, clean, courteous and did me an excellent service. I would use them again. They're very cooperative and try to work with your time constraints. If something comes up and they can't make it when they said they would, they give you a call, tell you when they will be there, and they hold to that.
