My spring broke and I was stranded at home. I called Discount Garage Doors around 1:30. Brian and Chad showed up shortly after 3:30. After examining my situation, Brian suggested they install 2 springs to replace my single spring so that if one spring fails the other will still allow me open the door. By 4:30 they were done and gone. The price was good and I have a 5 yr warranty on both springs! Thanks guys!
