There's a particular sound Commerce homeowners dread: a sudden, loud bang from the garage. almost like a gunshot. followed by a door that simply won't open. Nine times out of ten, that's a broken garage door spring. And while it feels sudden, the reality is that spring failure almost always has warning signs that showed up weeks or even months beforehand.
Commerce is a city where most residential homes are mid-century builds in neighborhoods like Bandini, Rosewood, and the Village. houses with attached garages whose doors get used multiple times a day. If your family runs four or more cycles (opens and closes) daily, your springs are accumulating wear fast. Understanding the warning signs can save you from being stuck with a car trapped in the garage on a weekday morning.
Torsion springs mount horizontally above the door on a metal shaft and twist under tension as the door moves. Extension springs run along the horizontal tracks on either side of the door and stretch as the door opens. Both types do the same job: counterbalancing the weight of the door so your opener motor doesn't have to do all the heavy lifting on its own.
Most standard springs are rated for around 10,000 cycles. one cycle being a full open and close. If your household uses the door four times a day, that translates to roughly seven to nine years of lifespan. Heavier doors, or doors used more frequently, wear springs out faster. Spring life in Southern California can also be shortened by the heat-driven expansion and contraction cycles that Commerce homeowners deal with every year.

This is the most reliable early signal. Disconnect your opener using the red emergency release cord and try to lift the door manually. A properly balanced door. supported by healthy springs. should lift with minimal effort and stay at waist height on its own. If it feels like you're lifting dead weight, or if it falls when you let go, the springs are no longer doing their job.
A snapping torsion spring unwinds in a fraction of a second and produces a noise that can sound like a gunshot or a car backfiring. If you hear this from inside the house, stop using the door immediately. Do not attempt to operate it manually or with the opener. and don't let kids or pets near the garage until a technician has assessed it. Contact us for same-day service if this happens.
If one spring fails while the other is still functional, the door will tilt noticeably to one side as it opens or closes. This imbalance puts serious extra stress on your opener motor and on the remaining spring, which is now carrying more than its share of the load. Left alone, this typically causes a second failure within a short period.
A broken torsion spring will show a clear gap. usually about two inches. in the coil where it snapped. Even before a full break, look for signs of rust (which makes the metal brittle and more prone to sudden failure) or coils that appear stretched or elongated rather than tightly wound. Inspect the springs visually every few months. You're looking for anything that doesn't look uniform and tight.
Your garage door opener is not designed to lift the full weight of the door on its own. When springs weaken, the opener has to compensate. you'll hear it straining, humming under load, or stopping partway through the lift. This isn't just an opener problem; it's a symptom of a spring problem that, if ignored, will burn out the opener motor and turn a spring replacement into a much more expensive job.
A failing spring can't properly control the descent of a heavy door. If your door slams shut or drops faster than it used to, that's a safety hazard. not just an inconvenience. A door dropping at speed can seriously injure anyone standing underneath it.
When a torsion spring breaks, it releases tension from the cable system. You may notice the lift cables hanging slack or wrapped unevenly around the drum even if the spring itself looks intact from a distance. Loose cables are a direct sign that the spring tension holding the system together has failed.
This cannot be overstated. Garage door springs operate under hundreds of pounds of stored tension. An improperly handled spring replacement can result in broken fingers, facial injuries, or worse. Unlike lubricating rollers or tightening loose bolts. tasks a careful homeowner can handle. spring work requires specialized winding bars, proper training, and an understanding of the exact spring spec for your door's weight and size.
When both springs are being replaced (which is recommended even if only one has broken, since the remaining spring is near the end of its lifespan anyway), a professional technician will also inspect cables, rollers, and the opener to make sure the failure hasn't caused downstream damage. Check the FAQ page for common questions about what a spring replacement service involves.
While springs will eventually wear out no matter what, there are a few things Commerce homeowners can do to get the most out of them:
- Lubricate springs every three to six months with a garage-door-specific lubricant. This reduces friction in the coils and slows down wear. - Test door balance twice a year using the manual lift test described above. - Don't let minor issues linger. A door that's been running slightly off-balance for months is doing slow damage to every component in the system. - Ask about high-cycle springs when you do need a replacement. Springs rated for 25,000 or 50,000 cycles cost more upfront but can last two to four times as long as standard springs. a worthwhile upgrade for households in Commerce, Montebello, or anywhere with heavy daily use.
Garage Door Company Commerce can assess whether your current springs are approaching the end of their rated life during any routine service visit. often catching the problem before it becomes an emergency. Explore our service areas to confirm we cover your neighborhood.
Q: Should I replace both springs even if only one broke? A: Yes, almost always. If one spring has reached the end of its lifespan and snapped, the other is typically at a similar point in its wear cycle. Replacing both at the same time costs only slightly more than replacing one. and avoids a second callout (and another stuck door) a few weeks later.
Q: How much does garage door spring replacement typically cost? A: Costs vary based on door weight, spring type (torsion vs. extension), and whether you upgrade to high-cycle springs. The job usually takes 60 to 90 minutes when done by a professional who stocks the right parts on their service vehicle.
Q: I heard a loud bang last night but the door still opens. Do I need to act immediately? A: Yes. If you heard a snap and the door still operates, it may be running on one spring or the opener is compensating for the failure. Every additional cycle risks further damage to the opener, cables, and tracks. and increases the chance of an unsafe situation. Stop using the door and get it inspected right away.
