If you've ever heard a sudden loud bang come from your garage. like a gunshot. and then found your door won't budge, there's a very good chance a spring just let go. It's one of the most common calls we get here in Rolling Hills, and it tends to catch homeowners completely off guard. The door was working fine last week. Now it's dead weight.
Living on the Palos Verdes Peninsula means your garage door hardware deals with something that homes in, say, the San Fernando Valley never have to contend with: coastal salt air. That ocean breeze rolling up from the Pacific is beautiful. but it's quietly working on the steel components of your garage door system every single day. Springs corrode faster in this environment than in drier inland climates, which means Rolling Hills homeowners often find themselves dealing with spring issues earlier than the national average might suggest.
Most people have no idea how a garage door spring operates until it fails. Here's the short version: the spring (or springs) stores mechanical tension and does the actual work of lifting your door. Your opener motor just guides it. Without a functioning spring, that opener is trying to muscle a 200,400 lb door on its own. which is why the door goes nowhere when a spring snaps.
There are two types of springs you'll find on Rolling Hills homes:
- Torsion springs. mounted horizontally above the door opening. More common on the heavier ranch-style and Mediterranean estate doors found throughout this community. They're safer when they fail because they stay on the shaft rather than flying loose. - Extension springs. run along the sides of the door tracks. Less expensive upfront, but they carry higher injury risk when they break, since a snapped spring can shoot across the garage.
Given the large, often custom doors on Rolling Hills properties. some of which are solid wood carriage-style doors weighing hundreds of pounds. torsion springs are typically the right call.
Don't wait for the loud bang. Springs give warnings before they go completely:
The door feels unusually heavy. Disconnect your opener and try to lift the door manually. It should go up smoothly with one hand and stay open at about waist height. If it's straining or falls back down, your springs are losing tension.
Visible gaps in the coil. On a torsion spring, look for a gap or separation in the coil itself. that's a spring that has already partially broken.
The door moves unevenly. If one side rises faster than the other, or the door looks crooked mid-travel, you likely have uneven spring tension or a broken spring on one side.
Grinding or squeaking sounds. Some noise is normal with age, but grinding. especially near the top of the door. often points to spring or cable stress. Our post on essential garage door maintenance covers the lubrication steps that can extend spring life, but once that grinding becomes constant, it's time for an inspection.
Here's what homeowners reasonably want to know upfront. Spring replacement typically runs $250 to $450 for a standard job, with most homeowners landing around $300,$350 for a torsion spring replacement on a single-car door. Double-car doors or heavier custom doors can push costs higher.
One important point: if one spring breaks, replace both. Springs are installed as a matched pair and wear at the same rate. The second spring is almost always close to failure when the first one goes. and replacing just one sets you up for another service call within weeks. Any reputable technician will tell you the same thing.
For the large, insulated, or decorative wood doors common on estates along Crest Road and Eastfield Drive, you may need heavier-duty springs or commercial-grade hardware. and that will bump the price up accordingly.

It has to be said clearly: garage door spring replacement is one of the most dangerous home repairs a homeowner can attempt. Torsion springs store an enormous amount of mechanical energy. When that energy releases uncontrolled. which it will if you don't have the right winding bars and know exactly what you're doing. the results can be catastrophic. Serious injury and property damage are well-documented outcomes of DIY spring attempts.
This isn't the kind of caution you hear about changing a light fixture or patching drywall. This is real. Leave it to a trained technician with the proper tools.
Most quality torsion springs are rated for 10,000 to 20,000 cycles. one cycle being one open and one close. For a household that uses the garage door four times a day, that works out to roughly 7,14 years. In a coastal environment like Rolling Hills, where salt air accelerates metal fatigue, leaning toward a higher-cycle spring is a smart investment. Ask your technician about high-cycle spring upgrades. they cost a bit more upfront but can nearly double the lifespan.
Regular lubrication (a silicone-based spray, not WD-40) applied two to three times a year will also help. Rancho Palos Verdes neighbors deal with the same conditions, and the ones who keep up with simple maintenance consistently get more life out of their hardware.
If you're unsure about your current springs or just want a second opinion, reach out to our team. we're happy to take a look and give you a straight answer about what you're actually dealing with.
Q: Can I still use my garage door if one spring is broken? A: Technically, some doors will still move with a broken spring, but you should not operate the door. Forcing the opener to work without proper spring support strains the motor and can damage the opener, cables, and tracks. turning a $300 repair into a much larger one. Keep the door closed and call a technician.
Q: How do I know if I have torsion or extension springs? A: Torsion springs are the large coil(s) mounted horizontally above the door, running parallel to the top panel. Extension springs run along the horizontal tracks on either side of the door and stretch as the door closes. If you see a single large coil centered above your door, that's a torsion spring system.
Q: Is it worth upgrading to higher-cycle springs when I replace them? A: For most Rolling Hills homeowners, yes. Higher-cycle springs (rated at 25,000 cycles or more) cost more upfront but last significantly longer. especially in a coastal environment where corrosion is an ongoing factor. If your current springs lasted less than eight years, it's a strong signal to upgrade rather than replace with the same grade.
