Garage door springs are the hardworking heroes nobody thinks about until they snap. There are two main types: torsion springs (wound above the door) and extension springs (on the sides). Most Petaluma homes run torsion. They last 7 to 9 years with regular use. When one breaks, your door becomes a 300 to 400 pound dead weight. Don't DIY this. A snapped spring can seriously injure you.
I've been pulling garage doors open and replacing springs for 15 years. I've seen too many homeowners try YouTube fixes on something that looks simple but absolutely isn't. This post cuts through the confusion so you know exactly what's happening under your garage roof.
Torsion springs sit horizontally on a metal rod above your door opening. They twist like a clock spring, storing energy as your door goes up and down. One or two torsion springs carry the full weight. They're smooth, reliable, and last longer than extension springs.
Extension springs run vertically along the cables on either side of your door. They stretch and contract like rubber bands. You'll find these on older homes or smaller, lighter doors. Extension springs typically wear out faster because they endure more stress per cycle.
Most modern garages in Petaluma use torsion springs because they're safer. If an extension spring snaps, it can whip across your garage like a metal whip. A torsion spring failure is more contained (though still dangerous if you're standing underneath). Both types need professional replacement. Period.
Springs fail because they're metal under constant stress. Every opening and closing is one cycle. After 10,000 to 15,000 cycles (that's roughly 7 to 9 years for an average household), the metal fatigues. It weakens. Then one day your door won't budge, or it crashes down halfway.
Lack of maintenance speeds up failure. We recommend annual garage door tune ups to catch wear early. Rust, improper lubrication, and misalignment all shorten spring life. If your door sounds different, moves unevenly, or jerks on the way up, springs might be next. Don't wait for them to snap.
Temperature swings in the North Bay don't help either. Winter cold makes metal contract; summer heat expands it. These cycles add stress over time.

A snapped spring replacement typically runs between $250 and $450 per spring, depending on the type and your door's weight. Most residential doors need one or two springs. If both fail at once, expect $400 to $800 total parts and labor.
Why the range? Heavier doors (custom wood, insulated models) need stronger springs that cost more. Labor varies too. Some doors are easier to access than others. A springs replacement job takes 1 to 2 hours for a professional.

When you call for an estimate, we'll tell you upfront what you're paying for. No surprise charges. No upsell. Just honest work.
Annual maintenance isn't glamorous, but it catches spring problems early. During a tune up, we inspect spring tension, test door balance, and lubricate moving parts. Catching wear now saves you from a crisis later. Read our guide on how often you should get a garage door tune up in Petaluma for the full breakdown.
Proper lubrication extends spring life by a year or two. We use silicone or lithium spray (never WD-40). It reduces friction and prevents rust. If you live near the coast, corrosion is a real threat. Keeping springs lubricated helps fight the salt air.
I need to be direct: replacing garage door springs yourself is one of the most dangerous DIY projects you can attempt. Seriously.
Springs hold hundreds of pounds of tension. When you remove the bolt or cable holding that tension, the spring can unwind violently. I've seen hands broken, faces cut, and garage doors come crashing down. The hospital bills and scars aren't worth saving $200 to $400.
Even if you've done your research and feel confident, a slip of the wrench changes everything. Check our safety post on why DIY replacement is dangerous for real examples of what goes wrong.

How do I know if my garage door spring is broken? Your door won't open, or it opens very slowly and unevenly. You might hear a loud bang if the spring just snapped. Never try to force the door open manually. Call a professional immediately.
Can one spring break while the other is fine? Yes. Springs fail independently. However, if one is worn, the other is likely wearing too. We often recommend replacing both springs at the same time, even if only one snapped, for balanced, long-term performance.
How long does spring replacement take? A typical spring replacement takes 1 to 2 hours from start to finish. We handle the job while you're home and test everything before we leave.
What's the difference between a one-spring and two-spring door? Lighter residential doors usually have one torsion spring. Heavier or wider doors need two springs to balance the load. We'll determine what your door needs during the inspection.
Does homeowners insurance cover spring replacement? Rarely. Most homeowners policies treat spring failure as maintenance, not a covered event. Contact your insurance agent to confirm your specific policy.
