Garage Door Spring Replacement in City of Industry: What Homeowners Need to Know
2026-04-16 7 min read
If you've ever heard a loud bang come from your garage. the kind that sounds like a gunshot going off. there's a good chance a garage door spring just let go. It's one of the most common calls we get here at Garage Door Company City of Industry, and it happens more often than most homeowners expect. Springs are under enormous tension every single day, and in the San Gabriel Valley's climate. with warm, dry summers pushing into triple digits and cool, damp winters bringing fog and moisture. those temperature swings accelerate wear faster than most people realize.
Understanding your springs before one fails is the smartest thing you can do.
The Two Types of Springs You'll Find on Your Door
Most homes in and around City of Industry have one of two spring systems:
- Torsion springs mount horizontally above the door on a metal shaft. They twist to store energy and release it to lift the door. These are more common in modern installations, safer, and longer-lasting. - Extension springs run along the horizontal tracks on both sides of the door. They stretch and contract to help raise and lower the door. These are older technology, typically found on lighter doors or older homes, and should always have safety cables running through them.
Knowing which type you have matters. not just for replacement purposes, but because the failure signs look different for each. If you spot a visible gap of about 2 inches in a torsion spring coil, it has snapped. Extension springs may not show a gap but can appear visibly overstretched or hanging loosely.
Warning Signs Your Springs Are About to Fail
Don't wait for the dramatic snap. Springs usually give you clues before they go:
1. The door won't open all the way, gets stuck halfway, or refuses to close completely. This is often one of the first signs of trouble. the springs may no longer be providing enough tension to lift or lower the door properly.
2. The door feels unusually heavy. Springs are designed to carry most of the door's weight. When they weaken, that weight shifts to the opener or to your manual effort. A 200-pound door with a dead spring feels like 200 pounds.
3. The door doesn't stay open on its own. Your garage door should remain fully open without assistance. If it begins to slide down or won't stay up at all, that's a strong indication the springs have lost tension.
4. You hear squeaking, grinding, or popping. Not all spring trouble announces itself with a bang. Gradual wear sounds different. creaking during operation is a sign the metal is fatigued.
5. You notice visible rust or corrosion. City of Industry sits in a valley that can trap morning fog and humidity, especially in winter months. That moisture works on unprotected metal hardware, including springs. Rust accelerates fatigue and shortens spring life significantly.
If any of these ring true, don't ignore them. Check out our opener troubleshooting guide to rule out other causes before assuming it's the springs. but if the door won't lift at all, the spring is almost always the culprit.
How Long Should Springs Last?
A standard spring is rated for around 10,000 cycles, which translates to roughly 7 to 10 years for a household that uses the garage door 2 to 4 times per day. High-cycle springs (25,000 to 50,000 cycles) last longer but cost more upfront.
Here's an important detail most homeowners don't know: most garage doors have two springs installed at the same time. When one breaks, the second spring's life expectancy has likely already expired. Replacing both at the same time saves you from a second service call weeks or months later. and actually costs less overall than two separate visits.
For homes near La Puente or in the small residential pockets adjacent to Industry Hills, where older construction is common, it's worth asking a technician exactly how many cycles your current springs are rated for. Many older installations used lower-grade springs that simply weren't built to last.
Why You Should Never DIY a Spring Replacement
This is one of the few home repair jobs where we'll say it plainly: don't attempt this yourself. Torsion springs are under extreme tension. Mishandling them can result in severe injuries. and the door itself can drop unexpectedly, harming anyone or anything in its path. You'd be lifting 150 to 400 pounds with no mechanical assistance if something went wrong mid-repair.
Beyond the safety risk, installing the wrong spring. wrong size, wrong cycle rating. forces your opener to work harder than it was designed to, and will likely burn it out prematurely. A professional measures the door's exact height and weight, selects the correct spring, installs it to tension, and performs a balance test before leaving.

What Does Spring Replacement Actually Cost?
Residential garage door spring replacement in the greater Los Angeles area typically runs $150 to $350 for both materials and labor, depending on the type and number of springs. High-cycle springs cost more upfront but save money over time by lasting years longer. If additional components. cables, rollers, bottom brackets. show wear, addressing them at the same time makes financial sense.

What to Do Right Now If a Spring Has Broken
If you suspect your spring just snapped, here's the short version:
1. Stop using the door immediately. Every cycle adds stress to a system already compromised. 2. Don't try to manually lift a door with a broken spring. The weight is too much without mechanical assistance. 3. Don't pull the emergency release if the door is open or partially open. it can cause the door to drop. 4. Call a professional. This is not a watch-a-YouTube-video situation.

Frequently Asked Questions
Q: Can I still use my garage door if one spring is broken? A: Technically the door may still move with one working spring, but you shouldn't use it. Continuing to operate the door puts excessive strain on the opener and increases the risk of sudden, complete failure. Stop using it and call a pro.
Q: Should I replace both springs even if only one broke? A: Yes. and here's why. Both springs were installed at the same time and have the same number of cycles on them. If one failed, the other is near the end of its life too. Replacing both now is safer and cheaper than making two separate service calls.
Q: How do I know if I have torsion or extension springs? A: Look above the door when it's closed. If you see a thick coil mounted on a horizontal bar above the opening, that's a torsion spring. If you see thinner springs running parallel to the horizontal tracks on each side of the door, those are extension springs.
