Garage Door Spring Types in Costa Mesa: Torsion vs. Extension Explained
2026-08-02 7 min read A2Z Garage Doors
In our 15 years serving Costa Mesa, we've seen this problem again and again: homeowners don't know what type of spring they have until one fails. Torsion and extension springs do the same job but work completely differently. Understanding which one you have matters for safety, repair cost, and knowing when to call for help.
The Two Main Types: Torsion vs. Extension
Your garage door weighs 300 to 500 pounds. Springs counterbalance that weight so a small motor can lift it. Two designs do this job. See our guide on weather stripping & seals in costa mesa: stop drafts and energy loss.
Torsion springs sit horizontally above your door. They twist or rotate as the door opens and closes, storing energy like a wound clock spring. One snapped torsion spring means your door won't open without the motor straining dangerously.
Extension springs hang vertically on each side of the door. They stretch and contract like a rubber band. When one snaps, the other side still has tension, creating an unbalanced, unsafe condition. Read about garage door springs in costa mesa: repair vs. replace when they fail.
Both systems work. Neither is inherently better. But they fail differently and cost differently to replace.
Why This Matters for Your Safety
A snapped spring doesn't just inconvenience you. It's a safety hazard. When a torsion spring breaks, the full weight of the door transfers to the opener motor and cables. You'll hear grinding or clicking. The door may not open at all, or it opens and falls hard.
Extension springs fail with less drama but equal danger. The door becomes unbalanced. It can jam in the tracks. If you're underneath when it happens, the weight risk is real.
We've also written about what to do when a spring snaps suddenly. Don't try to operate the door yourself. Call us first.
Single vs. Double Spring Systems
Most Costa Mesa homes use one torsion spring. Larger or heavier doors sometimes have two. Extension spring doors almost always have two (one per side).
If you have a single torsion spring and it breaks, your door is completely inoperable. Two torsion springs share the load. One failing won't stop the door, but you'll feel it and hear it. Same-day service becomes critical because you can't safely use the door until both are replaced.

Spring Lifespan and Replacement Cost
Torsion and extension springs last roughly 7 to 9 years with normal use. That's about 10,000 cycles (one cycle = door opens and closes once). Heavy use or poor maintenance cuts that short.
Torsion spring replacement typically costs more than extension springs. Torsion springs are harder to install and require special tools. Extension springs are simpler but two must be replaced together for safety and balance.
When you get an estimate, ask whether the job includes new cables and hardware. Springs don't exist in isolation. If your cables are worn, they'll fail soon after spring replacement. We can provide a detailed cost estimate during a free consultation. Schedule a free quote today.
How to Know Which Type You Have
Walk into your garage and look above the door. Do you see one or two thick metal coils running horizontal? That's torsion. See two vertical springs on the sides? Extension springs.
If you're uncertain, don't guess. Call us. We'll identify your system and explain exactly what you need.
When to Repair vs. Replace
A snapped spring always needs replacement, not repair. You cannot patch or weld a broken spring safely. The tension is too high and the risk too great.
We've detailed the repair versus replacement decision in another guide focused on spring failure. The short answer: springs get replaced. Doors sometimes get repaired.
If your springs are aging but not broken, replacement is preventive maintenance. Catching them before they snap avoids emergency calls at night or on weekends when rates spike.
Why Professional Installation Matters
Springs are under extreme tension. A torsion spring can unwind violently if mishandled. Extension springs snap with enough force to cause serious injury.

Frequently Asked Questions
What's the difference in cost between torsion and extension spring replacement? Torsion springs usually cost $200 to $300 more to replace because installation is more complex and requires specialized winding tools. Both systems include labor, hardware, and cables in the final bill.
Can I replace just one spring if I have two? No. Both springs must be replaced together, even if only one is broken. Springs wear at the same rate. Replacing one leaves the other to fail within weeks, creating an imbalanced, unsafe door.
How long does spring replacement take? Most jobs take one to two hours from arrival to completion. We'll inspect your entire system while we're there to catch any other wear or damage.
Is spring replacement covered by homeowner insurance? Rarely. Spring failure is typically considered wear and tear or maintenance, not a covered loss. Check your policy, but expect to pay out of pocket.
What's the warning sign before a spring snaps? Listen for squeaking or creaking above the door. If the door feels heavier than usual or jerks when opening, a spring is likely weakening. Call before it breaks completely.
