Most homeowners in Lomita don't think about their garage door springs until they hear a sound like a gunshot echoing from their garage. and suddenly their door won't budge. It's one of those repairs that feels like it comes out of nowhere, but the truth is that springs almost always give warning signs well before they fail completely.
Given that Lomita's housing stock leans heavily toward mid-century ranch homes and post-war bungalows. many of which still have their original or single-replacement garage door systems. spring wear is something local homeowners should be watching for proactively. A door that's been opening and closing two to four times a day for the past decade has put serious mileage on its spring system.
Your garage door weighs anywhere from 150 to 300 pounds. The springs. not the electric opener. are what actually do the heavy lifting. The opener just guides the movement. Torsion springs (mounted horizontally above the door opening) store mechanical energy when wound, then release it to lift the door. Extension springs run along the side tracks and stretch to provide the counterbalance force.
Most standard springs are rated for around 10,000 cycles. At a typical rate of four cycles per day for a Lomita household, that works out to roughly seven to nine years of normal use before replacement becomes necessary. Coastal conditions. the salt air, humidity, and temperature variation that come with South Bay living. can shorten that window.

Here's an easy test: disconnect your opener by pulling the red emergency release cord, then try lifting the door by hand. A properly balanced door should feel relatively light and stay in place when raised halfway. If it feels like you're lifting dead weight, or if it slowly falls back down when you release it, your springs are losing tension and may be close to failure.
This is also the test that will tell you how your door will behave during a power outage. something worth knowing before it happens.
This is the classic spring-break moment. A sudden, loud noise. often described as sounding like a gunshot or a firecracker. coming from a closed garage is almost always a torsion spring snapping. Since springs are under enormous tension, they release that energy violently when they break.
If this happened and your door now won't open, don't try to force it. Call a professional immediately. Garage door springs are under high tension and can be genuinely dangerous to handle without proper tools and training. this is not a DIY repair.
Take a look at the torsion spring above your door (don't touch it. just look). A healthy spring forms one continuous, tightly wound coil. If you see a gap. even a small separation. the spring has snapped and is no longer intact. It cannot provide the tension needed to support the door's weight, and continuing to operate the door in that condition risks damaging the opener, cables, and tracks.
If your door tilts to one side when it opens, hangs lower on one side when closed, or moves in a jerky, stuttering motion rather than a smooth arc, one spring has likely failed while the other is still partially functional. This imbalance puts serious extra stress on your opener motor and the remaining hardware. Left unaddressed, it often turns a spring repair into a more expensive multi-component job.
Homeowners in Torrance and other neighboring cities report the same issue. and the cause is almost always a spring that's been quietly degrading for months before the movement problem becomes obvious.
If your opener is working harder than it used to. making a straining or whirring sound, moving slower, or reversing before the door fully opens. the spring system may no longer be providing adequate counterbalance. The opener is designed to guide a balanced door, not to do all the lifting itself. Running it in this condition wears out the motor prematurely.
This is also worth cross-referencing with our FAQ page. a straining opener is one of the most common complaints we hear, and the spring is the culprit more often than people expect.
The single most important thing is this: do not ignore it and keep using the door. A failing spring can fail completely at any moment, and a 200-pound door dropping without proper counterbalance is a serious safety hazard. especially in households with children or pets.
Stop using the opener, keep people and vehicles out from under the door, and contact a qualified technician. Garage Door Lomita handles spring replacements promptly and with the right parts for your specific door weight and configuration. You can reach out to schedule a repair any time.
When a spring is replaced, it's standard practice to replace both springs at the same time. even if only one has broken. The other spring has experienced the same amount of wear and will typically fail soon after. Replacing them together saves you a return service call and keeps your door balanced correctly.
You can't prevent springs from eventually wearing out, but you can slow the process:
- Apply a silicone-based lubricant to the springs every three months. this reduces friction and slows rust formation, Visually inspect the springs monthly for rust, gaps, or uneven coil spacing, Have an annual professional tune-up done. a technician can spot tension loss or early corrosion before it becomes a failure
In a coastal community like Lomita, that monthly visual check is especially worth doing. Salt air accelerates rust on spring coils, and a rusty spring becomes brittle and prone to snapping well before it reaches its cycle limit.
Q: Can I replace just one broken spring instead of both? A: Technically yes, but it's not recommended. Both springs have the same age and wear history, so the second one is likely to fail soon after the first. Replacing both at the same time costs less than two separate service calls and ensures your door is properly balanced.
Q: How much does a garage door spring replacement typically cost? A: Costs vary depending on the type and size of spring your door requires, but professional spring replacement generally runs in the range of $150,$450. The exact price depends on whether your door uses torsion or extension springs and how many are needed. Always get a quote before work begins.
Q: Is it safe to manually open my garage door if I think a spring is broken? A: Exercise extreme caution. If a spring has broken, the door loses most of its counterbalance and becomes very heavy. and potentially dangerous to handle. If you must open it, have another adult help support the weight and only raise it enough to get a vehicle out. Then leave it closed and call for service rather than continuing to use the door.
