There's a sound that Hermosa Beach homeowners describe the same way every time: like a gunshot from inside the garage. If you've heard it, you already know what happened. a garage door spring snapped under full tension. If you haven't heard it yet, this post is for you.
Springs are the most mechanically stressed components in any garage door system. They do the actual heavy lifting. counterbalancing a door that can weigh anywhere from 150 to over 300 pounds so your opener motor doesn't have to work alone. When they fail, the whole system fails with them. And in a coastal city like Hermosa Beach, where salt air accelerates metal fatigue, springs tend to fail on the earlier end of their expected lifespan.
Here's what to watch for before you're left with a door stuck in one position and an emergency repair call on your hands.
This is often the first sign homeowners notice, and they usually chalk it up to the opener getting old. Try this test: disconnect the automatic opener and try lifting the door manually to about waist height. A properly balanced door should feel relatively light and stay in place when you let go. If it feels like you're lifting dead weight, or if it immediately starts to fall back down, your springs are losing tension or have partially failed.
This imbalance also puts enormous extra strain on your opener motor. which means ignoring worn springs often leads to a second repair bill for the opener.
Torsion springs. the type mounted horizontally above the door opening. are designed to form one continuous coil. If you look up at the spring and notice a gap or separation in the coil, the spring has snapped. This is not a "monitor it" situation. A broken spring can't support the door's weight, and operating the door in this condition risks the door dropping suddenly or causing damage to cables and tracks. Stop using the door and get in touch with us for same-day service.
Most residential garage doors use two springs. one on each side. When one spring fails while the other still functions, the working spring pulls its side up while the dead side drags. The result is a door that tilts, jerks, or appears crooked as it moves. This uneven strain also damages the cables and tracks over time, so what starts as a single spring replacement can become a more involved repair if left alone.
Some operational noise is normal, especially in older doors. But if you've noticed a change in how your door sounds. new squeaking, grinding metal, or intermittent popping. that's worth paying attention to. In Hermosa Beach's humid, salty environment, springs corrode from the outside in. Surface rust creates friction between the coils, and that friction produces sound before it produces failure. Think of unusual noise as an early warning system.
Applying a silicone-based lubricant to the springs can temporarily quiet the noise, but it doesn't fix the underlying corrosion. If the noise returns quickly or doesn't improve, the springs likely need professional inspection. Our frequently asked questions page has more detail on what normal garage door sounds versus warning sounds look like.
A healthy spring system controls how quickly your door lowers. If the door is dropping faster than it should. or slamming down at the end of its travel. the springs aren't providing enough resistance on the way down. This is a safety issue, particularly in homes with children or pets who might be near the door as it closes.
Don't assume this is an opener adjustment issue until the springs have been checked. In many cases, the opener settings are fine. it's the springs that have lost the tension needed to slow the descent.
Your garage door opener is designed to lift a counterbalanced door. one where the springs are doing most of the work and the motor just provides movement. If the springs are weak or broken, the opener suddenly has to lift the full weight of the door on its own. You'll often hear the motor strain or hum louder than usual. In some cases, it will stop mid-lift as a self-protection measure.
If your opener is acting up and the door itself seems fine visually, always check the springs before assuming the motor is the problem. Replacing an opener when the real issue is a worn spring is an expensive mistake.
Standard garage door springs are rated for around 10,000 cycles. one cycle being a single open and close. At four uses per day (a typical Hermosa Beach household pulling the car in and out twice), that works out to roughly seven to nine years under normal conditions. In coastal environments with elevated humidity and salt exposure, expect that timeline to shorten.
If your springs are approaching or past the seven-year mark, or if you can see visible rust or discoloration on the coils, it makes sense to get them inspected proactively. A preventive spring replacement is dramatically cheaper and less disruptive than an emergency call at 7 a.m. when you can't get your car out of the garage.
This is worth saying clearly: the combination of persistent coastal humidity and salt-laden air that makes Hermosa Beach such a desirable place to live is hard on metal under tension. Springs and cables are particularly vulnerable because they're always under load. salt corrosion weakens metal that's already stressed, increasing the chance of sudden failure. Homes in the Sand Section and along the Strand face the most exposure, but the entire city sits close enough to the Pacific that no property is really immune.
Garage Door Hermosa Beach sees a higher rate of spring-related calls compared to inland service areas for exactly this reason. It's not that the springs are lower quality. it's the environment they're working in.
First: don't try to replace springs yourself. Torsion springs store enough mechanical energy to cause serious injury when released improperly. This is genuinely one of the few home repairs where the risk of DIY is significant enough that professionals strongly advise against it.
If you notice any of the signs above, stop using the door until it's been inspected. Check our services page for spring replacement and tune-up options, or contact us directly to schedule a visit. Most spring replacements take under 90 minutes, and a trained tech will inspect cables, rollers, and the opener at the same time to make sure nothing else was stressed by the failing spring.
Catching this early is always better. for your wallet, your schedule, and your safety.
Can I still use my garage door if one spring is broken? Technically the door may still move, but you shouldn't use it. A broken spring means the door is unbalanced and the opener is taking on load it wasn't designed for. Continued use can damage the opener motor, cables, and tracks. and creates a real risk of the door dropping suddenly. Treat a broken spring as an out-of-service situation until it's repaired.
Should I replace both springs at the same time, or just the one that broke? Almost always, both. If one spring has failed after years of use, the other is at a similar point in its wear cycle and will likely fail soon after. Replacing both at the same time costs less than two separate service calls and ensures the door is evenly balanced. Any reputable technician will recommend replacing the pair.
How long does a garage door spring replacement take in Hermosa Beach? For most residential doors, a professional spring replacement takes between 60 and 90 minutes, including inspection of related components. Same-day appointments are typically available for urgent situations.
