Garage Door Spring Repair in Lomita: What You Need to Know Before Calling
2026-04-03 6 min read
If you've ever walked into your garage in the morning, hit the button on your opener, and heard either a loud metallic bang or nothing at all. there's a good chance your garage door spring has failed. It's one of the most common service calls we get here in Lomita, and it tends to catch homeowners completely off guard.
Understanding how springs work, why they fail, and what to expect during a repair can save you time, money, and a fair amount of frustration.
How Garage Door Springs Actually Work
Your garage door is heavy. A standard single-car door typically weighs between 130 and 150 pounds. A double door can push 200 pounds or more. Springs exist to counterbalance that weight so the opener (and you, when opening it manually) don't have to do all the work alone.
There are two main types used in residential garages:
- Torsion springs are mounted on a metal bar directly above the door opening. They wind and unwind to store and release energy as the door moves. Most modern doors use this system. - Extension springs run along the horizontal tracks on either side of the door, stretching and contracting with each cycle. They're more common on older homes and lighter doors.
In Lomita's mix of mid-century ranch homes, post-war bungalows, and 1970s split-levels, you'll find both systems. sometimes on doors that haven't been touched in decades.
Why Springs Break
Simple Wear and Tear
Springs are rated by cycles. one cycle equals one full open-and-close sequence. Most standard springs are rated for around 10,000 cycles. If you use your garage door three to four times a day, that adds up to roughly 1,200 to 1,500 cycles per year, meaning a spring could realistically reach the end of its life within seven to ten years. Heavier use shortens that window.
Coastal Corrosion
In the South Bay, this lifespan can be even shorter. Lomita's proximity to the coast means springs are regularly exposed to salt-laden marine air, and rust buildup inside the spring coils increases friction and stress on the metal. A spring already weakened by age fails even faster when corrosion is added to the equation. If you haven't read about how salt air affects your entire door system, our post on how Lomita's coastal air damages garage doors goes into detail worth knowing.
Lack of Lubrication
Dry, unlubricated springs wear out faster. A few minutes with a silicone spray twice a year can meaningfully extend their life. It's that straightforward. and that often skipped.
The Warning Signs to Watch For
Springs don't always break with a dramatic bang (though they can. the sound is genuinely startling and has been compared to a gunshot by more than one homeowner). Here are the more subtle signs that failure is approaching or has already happened:
- The door feels much heavier than usual when you try to lift it manually - The door stops about six inches off the ground and won't continue opening - You hear grinding or squeaking during operation - The door moves unevenly. one side rises faster than the other - Cables are hanging loose or appear slack on one side - A visible gap in the spring coil. this means it has already snapped
If you notice any of these, stop using the door until it's been inspected. Continuing to run the opener with a broken spring puts serious strain on the motor and can damage other components. Review our frequently asked questions for more on what to do in common scenarios like this.
Why You Should Not Attempt This Repair Yourself
This is important, so it's worth being direct: garage door spring replacement is genuinely dangerous for anyone without professional training and the right tools.
Torsion springs in particular store an enormous amount of mechanical energy when wound. That tension doesn't release gently. if handled incorrectly, a spring can snap back with enough force to cause serious injury or significant property damage. The stored energy is enough to pull an untrained person off a ladder or send a spring flying across the garage.
This is not the kind of repair that fits in the "capable homeowner" category alongside replacing a light switch or fixing a leaky faucet. Leave it to a professional, every time.
What to Expect From a Professional Spring Repair
When you schedule a repair with our team, here's how the process typically goes:
1. Diagnosis. We confirm the spring failure and inspect the rest of the system. A broken spring often puts additional stress on cables, rollers, and the opener, so those get checked too. 2. Spring replacement. If one torsion spring has broken, it's almost always best to replace both at the same time. The surviving spring has the same wear history as the broken one, meaning it's likely to fail soon anyway. Replacing both now saves you a second service call in the near future. 3. Tension adjustment and balance test. After installation, we adjust the spring tension and test the door's balance. A properly balanced door should hold itself in place when lifted halfway by hand, without falling or rising on its own. 4. Full system check. Springs don't operate in isolation. We'll check cables, tracks, rollers, and the opener to make sure nothing else is compromised.
Most spring repairs in the Los Angeles area are completed in under two hours, and in many cases, same-day service is available.
How Long Will New Springs Last?
Standard replacement springs are typically rated for 10,000 cycles. Higher-cycle springs. often rated for 25,000 to 30,000 cycles. are available at a modest upgrade in cost and are worth considering if you're a high-frequency user or want fewer repairs down the road. Ask your technician which option makes sense for your door setup.

Frequently Asked Questions
Q: My garage door opener is running but the door isn't moving. is it definitely the spring? A: Not always, but a broken spring is one of the most common causes. When a spring breaks, the door becomes too heavy for the opener to lift safely, so the motor runs but the door stays put. You may also hear the motor straining. A technician can confirm the diagnosis quickly.
Q: Can I still get into my garage manually if a spring is broken? A: Technically yes, but it takes two people and a lot of effort. the door will feel like dead weight without the spring's counterbalance. Disengage the opener by pulling the red emergency cord, then carefully lift from the bottom with both hands. Don't try this alone, and don't leave the door propped open unattended.
Q: My house was built in the 1960s. does the age of the home affect the spring replacement? A: Older homes often have extension spring systems rather than the more modern torsion spring setup. Both are repairable, but the parts and process differ. In some cases, we recommend upgrading to a torsion system during replacement because it tends to be smoother, quieter, and safer.
