Your garage door likely has either a torsion spring or an extension spring, and the difference matters when something snaps. Most Santa Rosa homes use torsion springs because they're safer and last longer, but knowing which one sits above your door helps you understand repair costs and urgency.
Springs do the heavy lifting. They counterbalance your door's weight, which typically ranges from 300 to 500 pounds depending on size and material. Without a functioning spring, your opener works twice as hard, and your door becomes a genuine safety hazard. Springs fail over time. The average lifespan is 7 to 9 years with normal use, though this varies based on climate and how often you open and close your door.
That's why identifying your spring type matters before you call for help. It affects diagnosis, pricing, and the timeline for getting your door working again.
Torsion springs wind tightly around a horizontal rod mounted above your garage door opening. As your door lowers, the spring twists (torques) and releases stored energy to help lift it back up. They're mounted in the center and work as a team, usually in pairs.
Most new homes in Santa Rosa and surrounding areas use torsion springs. They last longer, provide smoother operation, and are far safer than their alternative. If one torsion spring snaps, your door won't crash down on its own because the second spring can hold it. A snapped spring is still a repair you need to address quickly, but it's less of an emergency.
Torsion springs do cost more to replace, typically because installation requires specialized tools and expertise. That's also why it's not a DIY job. The tension in these springs is extreme, and improper handling can cause serious injury.
Extension springs hang on either side of your door, parallel to the cables. They stretch and contract as your door moves up and down. When the door lowers, the springs extend. When it rises, they compress and help lift the weight.
Older homes and lighter-duty garage doors sometimes use extension springs. They're cheaper upfront but wear out faster than torsion springs. The biggest downside: if an extension spring snaps, your door can drop suddenly. This is why extension springs have safety cables running through them. Those cables catch the spring if it fails, preventing a dangerous drop.
Extension springs typically last 5 to 7 years with regular use. They're also more prone to rust and corrosion, especially in areas with moisture like Santa Rosa's winter months.

Walk into your garage and look directly above your door. If you see a tightly wound metal coil running horizontally across the top, that's a torsion spring. If you see springs hanging vertically on both sides near the cables, those are extension springs.
Don't touch either type. Springs under extreme tension can cause serious injury if mishandled. This is simply a visual identification step.

How much does it cost to replace a garage door spring in Santa Rosa? Torsion spring replacement typically costs between $300 and $500 per spring, while extension springs run $200 to $400 each. Labor and the number of springs needed affect the final price. We always provide a free estimate before starting work.
Can I replace a garage door spring myself? No. Spring replacement requires specialized tools and knowledge of extreme tension mechanics. Improper handling causes serious injury or death. Always hire a licensed professional for spring work.
How long do garage door springs last? Torsion springs last 7 to 9 years with normal use. Extension springs typically last 5 to 7 years. Lifespan depends on climate, usage frequency, and maintenance habits.
What's the difference between a snapped spring and a worn spring? A snapped spring fails suddenly and prevents door movement. A worn spring loses tension gradually, making the door harder to open or causing it to close unevenly. Both require professional replacement.
Do I need to replace both springs if only one snaps? We recommend replacing both torsion springs at the same time, even if only one has failed. The second spring is likely near the end of its life and will fail soon. Replacing both prevents a second emergency repair weeks later.
