That loud bang from the garage was almost certainly a spring. We replace broken torsion and extension springs same-day — safely, because this is the one repair you should never DIY.
Garage door springs do the heavy lifting — literally. They counterbalance a door that weighs 150 to 400+ pounds, cycling thousands of times under extreme tension. In California's Central Valley, where summer garage temperatures soar past 110°F, springs fatigue faster; on the coast, corrosion eats at them. The average spring lasts 7–10 years, and when it goes, you'll hear it: a gunshot-loud bang, then a door that won't budge.
Spring replacement is the most dangerous common garage door repair — a slipping winding bar can cause serious injury in a fraction of a second. Our technicians do this every day: we measure, match the exact spring weight and cycle rating for your door, replace both springs as a balanced pair when appropriate, recalibrate the tension, and test the door's balance before we leave. Most replacements take under an hour.
The telltale signs: a loud bang, a door that won't open or feels impossibly heavy, and — for torsion springs — a visible 2–4 inch gap in the coil above the door. If the opener strains and gives up, the spring is the prime suspect.
We strongly advise against it. Torsion springs store enough energy to cause severe injury, and an incorrectly sized or tensioned spring will destroy your opener or slam the door. This is a same-day professional job — call us instead.
Yes, in most cases. Springs installed together have lived the same life; the second is living on borrowed time. Replacing them as a matched pair costs less than two separate visits and keeps the door balanced.
Most residential spring replacements are completed in under an hour, including rebalancing and safety testing.
We install high-cycle springs rated well above builder-grade, matched to your door's exact weight — typically good for many more years of daily use than the originals.
