We come out from Richmond, about 18 miles, with torsion bars, winding cones, and springs matched to your door's weight and drum size - not a universal spring that's close enough. The job starts with clamping the door in place, releasing tension on the old spring safely, and checking the cable, drums, and bearing plate while everything's apart, since a spring rarely fails alone on a door this old. We replace both springs on a two-spring torsion system even if only one broke - the surviving one is on the same clock and failing it a second time means a second call. Once the new spring's wound to the right turns for your door's weight, we cycle it several times and check balance by hand before we call it done.
