1. What brands do you recommend? 2. Where's the best place to buy (Cosco, Home Depot, Sears, etc)? 3. How many horsepower do I need?
I have a 2-car garage, with a door that rolls up, sheet metal, no insulation.
In case anybody recommends fixing a 14 year old garage door rather than replacing, here's the symptoms (it's a Stanley brand opener with chain drive):
A couple of days ago, the door started not shutting all the way. The first day it left a 1" gap, then the 2nd day about 2". On the 3rd day, when I was closing it, it only closed half way and then opened again, and it opened beyond the stop and the door actually hit the drive mechanism but I stopped it before it damaged the door. Can this type of problem be a simple re-calibration problem? I doubt it, and i'm afraid i'll damage the door or cause an unsafe situation if i just try to mess with it until it "seems" to work.
