How springs fail
The torsion spring above the door does the lifting. The opener only guides it. Each spring is wound to balance the door’s weight and rated for roughly 10,000 cycles. In a house where the door goes up and down four times a day, that is seven to ten years. Steel is least forgiving in the cold, so most of the springs we replace in Utah County snap on a January morning with a bang loud enough to be mistaken for a car backfiring.
What we do
We replace both springs, not just the broken one. They were installed together and have the same number of cycles on them, so the survivor is usually months from the same fate. Each new spring is sized to your door’s weight, height, and drum. Then we balance the door so it holds still at waist height, and check the cables, drums, and bearings the snap may have strained.
What it costs
Most pairs run $240 to $390 installed, depending on door weight and spring size. The technician quotes one flat price at the door before starting, and the springs we install carry a lifetime warranty for as long as you own the home.
