A snapped garage door spring leaves you stuck. The good news: knowing the difference between torsion and extension springs helps you understand what failed, why it matters, and what to expect when you call for help in San Clemente. Most residential doors use one or the other, and each has its own repair timeline and cost implications.
Springs do the heavy lifting. Your garage door weighs 300 to 500 pounds. Without springs, you'd need superhuman strength to open it manually. Springs counterbalance that weight so the opener can do its job with minimal effort. When a spring fails, your door either won't open at all or becomes dangerously heavy to operate.
Springs don't last forever. A quality set typically lasts 7 to 9 years with regular use. Salt air in coastal areas like San Clemente accelerates rust and wear. If your door is older than eight years and you live near the ocean, failure isn't a question of if but when. That's why understanding which type you have matters before something breaks.
Torsion springs mount horizontally above your door opening. They twist (or torque) as the door moves, storing and releasing energy in a controlled spiral. Most modern homes, especially in Orange County, use torsion springs because they're more durable and safer than their counterparts.
One torsion spring typically handles the load. A snapped torsion spring means your door won't open without professional help. The spring is under extreme tension, so replacing it requires specialized tools and training. This isn't a DIY job. Ever. A snapped spring can cause serious injury if mishandled.
The upside: torsion springs last longer and provide smoother operation. They're also more predictable in terms of failure timing. You usually get warning signs before a complete break, which we covered in our 5 warning signs you need garage door repair in San Clemente.
Extension springs run along the sides of your door opening. They stretch and contract like a slinky as your door moves up and down. You typically need two extension springs to balance the load properly.
Extension springs tend to wear faster than torsion springs. They're more prone to rust in our coastal climate and more susceptible to snapping without much warning. If one snaps, the other usually follows within weeks or months. That's why many homeowners replace both at once, even if only one failed.

Living near the coast means constant exposure to salt air. It corrodes metal faster than anywhere inland. Your garage door springs rust from the inside out, weakening the steel until they snap under normal use. Regular maintenance helps, but it can't fully stop the process.
This is why our coastal customers often experience spring failure sooner than the standard 7 to 9 year estimate. If you haven't had your springs inspected in over a year, or if you're noticing slower door operation, don't wait. Salt damage accelerates quickly once it starts.

Spring replacement costs depend on which type you have and whether you're replacing one or both. A single torsion spring typically costs less than two extension springs, but labor is usually the same. We provide an honest, itemized estimate before any work starts. No surprises.

How do I know if my garage door spring is broken? Your door won't open, opens slowly, or closes unevenly. You might hear a loud bang before it fails. If the door feels unusually heavy when you try to open it manually, a spring has likely snapped.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if improperly handled. Always hire a licensed technician with the right tools and training.
How long does a spring replacement take? Most replacements take 1 to 2 hours. Torsion spring jobs are typically faster than extension spring jobs. We can often fit same-day appointments for emergency calls.
Why do both my extension springs need replacing if only one broke? Extension springs wear together. If one snapped, the other is near the end of its life too. Replacing both prevents a second failure within weeks and ensures balanced door operation.
Does homeowner's insurance cover spring replacement? Rarely. Most homeowner policies exclude garage door springs from coverage. Check your specific policy, but plan to pay out of pocket for this repair.
