Why the failure is so loud
A wound torsion spring stores enough energy to lift your door thousands of times. When the steel fatigues past its rating, that energy releases in a single instant — homeowners routinely describe it as a gunshot. If that sound brought you here, the fix is routine and usually same-day.
Why springs die young in the valley
Springs live and die by cycles — one open-and-close is one. Builder hardware carries a 10,000-cycle rating, which a garage-as-front-door household burns through in five or six years. Riverside heat shortens the rating further: metal cycling in a 130-degree garage fatigues faster than the same metal on the coast. We install high-cycle springs — rated 20,000+ cycles — as the standard. The upgrade is modest; the lifespan roughly doubles. Heat changes every material decision out here.
Why we always quote the pair
On a two-spring door, both springs have lived identical lives — identical cycles, identical heat, identical fatigue. When one fractures, the other is statistically weeks behind it. Replacing one buys a second emergency call; replacing both means the next visit is a routine tune-up.
