After 15 years on service calls across Agoura Hills and the surrounding Santa Monica Mountains area, I can tell you one thing with absolute certainty: garage door springs confuse homeowners more than any other component. Let's cut through that confusion. There are two main types of springs you need to know about, and knowing the difference could save you money, time, and honestly, a trip to the emergency room.
Your garage door uses either a torsion spring or an extension spring system. These aren't interchangeable, and they work in completely different ways. See our guide on garage door cost & pricing in agoura hills: what you.
Torsion springs sit horizontally above your garage door opening. They twist and wind as your door opens and closes, storing and releasing energy like a wound-up clock spring. Most modern homes built in the last 20 years use torsion springs because they're safer, quieter, and last longer. If your door weighs 300 to 400 pounds, torsion springs are almost certainly doing the heavy lifting.
Extension springs run vertically along each side of your door, stretching as the door lowers and contracting as it rises. Older homes and lighter doors often use these. They're cheaper upfront but wear out faster and require more safety hardware to contain them if they snap. Read about garage door maintenance in agoura hills: what actually needs doing.
Here's what matters: a snapped spring isn't something you can patch. It needs replacement, period. Springs last roughly 7 to 9 years depending on usage. If your door is older than that and you haven't replaced springs yet, you're living on borrowed time.
I need to be direct here. Replacing garage door springs yourself is one of the most dangerous DIY projects a homeowner can attempt. Springs are under extreme tension. A torsion spring wound to full tension holds enough energy to cause serious injury or death if it suddenly releases. I've seen bruises, broken bones, and worse from springs gone wrong.
Our team at Garage Door Company Agoura Hills gets calls from people who tried this themselves and got hurt. Some tried to save money on the estimate and ended up spending more at an urgent care clinic. It's not worth it. A professional technician has the right tools, the knowledge to safely release tension, and the experience to do it correctly the first time.

Real talk on pricing. A single torsion spring replacement typically runs between $200 and $400 in our area, depending on the spring's size and quality. Extension springs are usually cheaper at $150 to $300 per spring. Most doors have two springs, so double that estimate. If both springs are old, replacing them together is smarter than replacing one now and one later.
Labor is the bulk of the cost. A technician needs 30 to 60 minutes per spring because the work is meticulous and must be done safely. Same-day service carries a small premium in Agoura Hills, but it beats waiting weeks with a non-functioning door.

Your door sounds different. It moves slowly or unevenly. One side hangs lower than the other. Those are all warning signs. A snapped spring is obvious: your door won't open at all, or it falls hard when you try. That's the point where you need help immediately, not eventually.
If you're unsure, schedule a free estimate and let a technician diagnose the problem. We'll tell you exactly what needs fixing and what your options are.
When you call for spring replacement, a good technician will inspect the entire system. They'll check the opener, the cables, the pulleys, and the tracks. Sometimes a snapped spring damages other components, and you need to know that upfront. They should provide a written estimate before any work starts and explain what they're doing.
Our team handles the whole job: safely releasing tension, removing the old spring, installing the new one, testing the door balance, and making sure everything operates smoothly. You get a warranty on parts and labor, too.
Springs wear out. It's not a matter of if, but when. The best approach is replacing both springs at the same time, even if only one has failed. Why? Because the other one is usually close behind, and you'll save on labor by doing it once instead of twice in six months.
If your door is over seven years old and you haven't had springs serviced, get an inspection now. Catching a worn spring before it snaps beats dealing with an emergency breakdown.

How long do garage door springs actually last? Torsion and extension springs typically last 7 to 9 years with normal use, which translates to roughly 10,000 open and close cycles. Climate, humidity, and how often you use your door affect lifespan. Springs in Agoura Hills weather tend to hold up well, but replacement is inevitable.
Can I replace just one spring if the other is still working? Technically yes, but it's not ideal. The second spring is usually wearing at the same rate and will fail soon after. Replacing both at once saves labor costs and prevents a second service call within months.
Why is my garage door uneven after a spring replacement? The door balance depends on both springs being equally matched and properly tensioned. If one spring is new and the other is old, or if tension isn't set correctly, the door hangs crooked. A professional technician balances the system as part of the service.
What's the difference between torsion and extension springs for cost? Extension springs cost less upfront, around $150 to $300 each, while torsion springs run $200 to $400. However, torsion springs last longer and are safer, making them the better long-term value for most homeowners.
Is spring replacement covered under warranty? Springs themselves typically carry a 1 to 5 year manufacturer warranty depending on the brand. Labor is usually warranted by the service company for 12 months. Ask for warranty details in writing before work begins.
