Broken Spring Repair in Trabuco Canyon, CA

Garage door springs do the heavy lifting — literally. A typical residential door weighs 130 to 400+ pounds, and torsion or extension springs store the mechanical energy that makes it possible to lift that weight by hand or with a modest opener motor. Springs are rated for a fixed number of open-close cycles, commonly around 10,000 cycles, which works out to roughly 7 to 10 years of average household use (about 3–4 cycles per day). Once a spring reaches the end of its cycle life, or is weakened by rust, corrosion, or temperature extremes, it can fail suddenly — usually with a loud bang.

There are two main spring systems: torsion springs, mounted horizontally above the closed door on a metal shaft, and extension springs, mounted above the horizontal tracks on either side of the door. Torsion springs are more common on modern doors and are generally considered more durable and safer when properly installed with safety cables, though both systems fail the same way — predictably, at end-of-cycle-life, and unpredictably, from cold-weather brittleness or corrosion.
