Your Garage Door Springs Are Telling You Something: Here's How to Listen
2026-03-21 6 min read
Of all the calls we get from homeowners in La Mirada, broken springs are near the top of the list. and almost every time, there were warning signs that went unnoticed for weeks. Springs don't usually fail without warning. They wear down gradually, and if you know what to look and listen for, you can get ahead of a failure before you're stuck with a door that won't open on a workday morning.
This is especially relevant for La Mirada's housing stock. The city is largely built out with mid-century and ranch-style homes. many of them originally constructed in the 1960s and 1970s. and a significant number of those garages have never had their springs replaced. If you bought a home here without asking about the garage door's service history, there's a real chance the springs are well past their rated lifespan.
How Springs Actually Work. and Why They Fail
Torsion springs sit horizontally above your garage door opening, mounted on a metal shaft. When you open the door, the spring unwinds, releasing stored tension that does most of the heavy lifting. When you close it, the spring winds back up. Every open-and-close cycle is exactly that: one cycle of tension.
Most standard torsion springs are rated for around 10,000 cycles. If your household opens and closes the garage door four times a day on average, you're looking at roughly seven years of use before the spring reaches the end of its rated life. Busier households. families where multiple cars come and go throughout the day. can burn through springs in four to five years.
Homes near Norwalk or Cerritos with multiple drivers in the household tend to see springs wear faster simply because the door cycles more frequently throughout the day. If your door gets used more than six to eight times daily, check in with our team about upgrading to high-cycle springs rated for 20,000 or more cycles.
Warning Signs You Should Never Ignore
The Door Feels Unusually Heavy
Here's a quick test any homeowner can do: disconnect the opener by pulling the red emergency cord hanging from the rail, then try to lift the door manually by hand to about waist height. Let go. A properly balanced door with healthy springs should stay in place. it shouldn't drift up or fall down. If the door feels like you're lifting dead weight, or if it drops the moment you release it, the springs are no longer doing their job of counterbalancing the door's weight.
This matters because a garage door can weigh anywhere from 150 to over 300 pounds. When the springs fail, the opener motor has to compensate. and it's not built to handle that load. Continued use with failing springs will burn out your opener motor, which is a much more expensive repair.
Uneven or Jerky Movement
When one spring is weaker than the other. or when one has snapped while the other is still partially functional. you'll see it in how the door moves. One side may lag behind the other, giving the door a lopsided look as it travels up or down the tracks. You might also feel a jerkiness or hesitation, particularly in the first few inches of travel. Don't dismiss this as a track issue until someone has checked the spring tension, because uneven spring tension is frequently the actual cause.
Loud Noises During Operation
A grinding or scraping sound as the door moves can mean worn rollers or a dirty track, but it can also indicate a spring that's under uneven stress. The most dramatic noise. and the one that gets people calling immediately. is a loud bang that sounds like a gunshot coming from the garage. That's almost always a torsion spring snapping under tension. If you hear it while you're home, stop using the door immediately and schedule a repair. Do not attempt to operate the door manually or with the opener after a spring break.
Visible Gaps or Rust on the Spring Coils
Take a flashlight and look at the spring mounted above your door. A healthy torsion spring has tightly wound coils with no separation. If you see a gap of an inch or more in the coil, the spring has snapped. Also look for rust discoloration or flaking. a rusty spring is brittle and far more likely to fail suddenly. La Mirada's mild winters still bring enough moisture between December and February to accelerate corrosion on springs that haven't been lubricated regularly.
The Opener Struggles or Stops Mid-Travel
If your opener hums loudly, strains, or reverses before the door is fully open, it's often interpreted as an opener problem. But before replacing your motor unit, have the springs checked. The opener's sensitivity settings are calibrated assuming the springs are doing their share of the work. When springs weaken, the opener hits its force limit trying to compensate and stops itself to avoid damage. This is a protective feature. and it's often the first sign homeowners notice that something is wrong with the spring system.

Why This Is Not a DIY Job
Garage door spring replacement comes up often in YouTube videos and home improvement forums, and we'll be straightforward: it's one of the genuinely dangerous home repairs a person can attempt. Torsion springs store a significant amount of mechanical energy. When that energy releases unexpectedly. and it can, without warning. it's capable of causing serious injury. The winding and unwinding process requires specific tools (winding bars, not screwdrivers) and knowledge of how to safely manage the tension.
Even experienced DIYers who've done plenty of home projects should hand this one off. The cost of professional spring replacement is modest compared to the cost of an emergency room visit or a damaged door from an improperly wound spring snapping mid-installation. Garage Door La Mirada carries properly rated springs for the common door weights found in La Mirada's ranch and traditional homes, and our technicians can typically complete a replacement in a single visit.
When to Replace Both Springs
If one spring breaks, replace both. even if the second spring still looks okay. Two springs installed at the same time wear at roughly the same rate. If one has reached the end of its life, the other is right behind it. Replacing just the broken spring means you'll likely be calling for service again within weeks or months when the second one goes. It also keeps the door balanced, which protects your tracks, cables, and opener from the uneven stress of mismatched spring tension.
If your home is one of La Mirada's older properties and you're not sure when the springs were last replaced, treat that as a reason to get them inspected sooner rather than later. Visit our service areas page to confirm we cover your neighborhood, or call to set up an inspection.
Frequently Asked Questions
How do I know if my garage door spring is broken versus just worn out?
A broken torsion spring will have a visible gap in the coil. usually an inch or more of separation. A worn spring may look intact but will show signs through performance: a door that feels heavy, moves unevenly, or causes the opener to strain. If you're unsure, the manual lift test is the easiest check: disconnect the opener and try to lift the door by hand to waist height. If it won't stay put, the springs need professional attention.
Can I still use my garage door if a spring breaks?
No. Operating the door with a broken spring puts the full weight of the door. often 200 pounds or more. onto the opener motor, which it isn't designed to handle. It also creates an unpredictable and potentially dangerous situation where the door can drop suddenly. Use the emergency release and keep the door closed until a technician can replace the spring.
How long does a garage door spring replacement take?
In most cases, a technician can complete a torsion spring replacement in one to two hours. If both springs are being replaced at the same time (which is recommended), the job is typically done in a single visit. The technician will also check cable tension, lubricate moving parts, and test the door balance before leaving.
