If you've ever dealt with a stuck garage door, you know how frustrating it is. Most of the time, a snapped garage door spring is the culprit. Springs support the entire weight of your door, which can exceed 400 pounds. When one fails, the door won't budge, and you're locked out of your garage. At Garage Door Avalon, we've seen this happen hundreds of times. Here's what you need to know about springs, why they break, and what repair actually costs.
Your garage door relies on either torsion springs or extension springs to lift and lower smoothly. Torsion springs sit above the door on a metal rod and twist to store and release energy. Extension springs run along the sides of the door and stretch to support the weight. Both types work under extreme tension, cycling 10,000 to 15,000 times over their lifespan. Most springs last 7 to 9 years with normal use. That's not forever, and it's important to understand what happens when they wear out.
The mechanism is elegant but unforgiving. When a spring snaps, there's no backup system. Your opener motor can't lift the door manually because the spring was doing 99 percent of the work. You'll hear a loud bang from the garage. The door will either hang in the open position or drop suddenly if it was closing. This is why we always recommend scheduling an inspection if your door feels heavier than usual or moves slower than it did six months ago.
Springs fail for predictable reasons. Rust and corrosion eat away at the metal, especially here in coastal Avalon where salt air accelerates decay. We've also seen springs snap from sudden temperature swings or from the door being forced open manually during a power outage. Poor maintenance plays a huge role too. Springs that go years without lubrication bend unevenly under load and fracture sooner.
Cheap replacement springs installed by inexperienced technicians fail faster because they're low-grade metal. We've seen it happen within 18 months. The cheapest option isn't always the honest option. We source springs built to last the full 7 to 9 year cycle, and we balance them properly after installation so both sides work as a matched pair.

Here's the real talk on pricing. A single torsion spring replacement runs $150 to $300, depending on spring quality and door weight. Extension springs cost $100 to $200 per side. If both springs have failed (common after years of use), you're looking at $300 to $600 total for parts and labor. Emergency service after hours or on weekends adds $75 to $150. We charge what the job is worth, not what we think you'll pay.
Many homeowners ask whether they should replace both springs at the same time, even if only one snapped. The answer is yes. When one spring fails, the other has usually been working overtime to compensate. Both are at the same age and stress level. Replacing just one leaves you vulnerable to another failure in weeks. Our estimate always includes replacing the matched pair.
For homeowners in nearby Long Beach or further inland in San Diego County, the cost structure is the same, though travel time may add to emergency rates. We serve all of San Diego and Orange County, and we quote honestly every time. Learn more about what emergency service really costs and when you should call.
A snapped spring is not a DIY repair. Spring replacement requires specialized tools, safety equipment, and precise balancing. Improper installation can leave one side carrying more load than the other, causing premature failure again. The tension is so high that a misaligned spring can snap and cause serious injury. We've seen it happen.
If your door is stuck closed and you need access urgently, check our after-hours emergency guide for temporary workarounds. Most of the time, we can get to you for same-day replacement. Call us with your door type and color, and we'll give you an honest estimate over the phone.

Regular maintenance catches spring wear before it becomes a failure. A yearly tune-up includes lubrication, visual inspection, and balance testing. We check for rust, listen for unusual noises, and measure spring tension. This costs about $100 to $150 and adds years to spring life. Our complete maintenance checklist walks you through what we do and why it matters.
Spring failure is preventable. The sooner you act on warning signs (slower movement, heavier feel, squeaking), the less you spend. Don't wait until the door won't open at all.
How long do garage door springs last? Most springs cycle 10,000 to 15,000 times and last 7 to 9 years under normal use. Coastal environments like Avalon see shorter lifespans due to salt air corrosion. Annual maintenance helps maximize their lifespan.
Can I replace a garage door spring myself? No. Spring replacement requires specialized tools and precise tension balancing. Improper installation risks catastrophic failure and serious injury. Always hire a licensed technician for this job.
What's the difference between torsion and extension springs? Torsion springs sit above the door on a horizontal rod and twist to support weight. Extension springs run along the sides and stretch. Torsion springs are more durable and common in modern doors.
How much does same-day spring replacement cost? Single spring replacement runs $150 to $300. Replacing both springs (recommended) costs $300 to $600 total. Same-day service adds $75 to $150 if outside normal hours.
What happens if I keep driving on a snapped spring? Don't. The door can drop suddenly and damage your car or cause injury. Stop using the door and call for same-day repair immediately.
