Garage Door Springs in Concord: Torsion vs. Extension (Which Do You Have?)

2026-09-22 5 min read

Most homeowners in Concord don't know which type of garage door springs they have until something breaks. That gap in knowledge costs money. Torsion and extension springs do the same job differently, and the type you own determines repair cost, safety risk, and how fast you need help. Let's cut through the confusion so you understand what's actually above your garage door.

The Core Difference: How They Work

Torsion springs wind up like a clock spring. They're mounted horizontally on a shaft above the door opening. When your door closes, the springs tighten. When you open it, they unwind and help lift the 300 to 700 pound door with mechanical advantage. One or two torsion springs handle all that tension.

Extension springs work the opposite way. They're mounted vertically on each side of the door frame and stretch when the door closes. Cables run through pulleys. When you open the door, the springs contract and help pull it up. You'll always see two extension springs, one per side.

Walk into your garage and look above the door. Horizontal metal rod with springs wound around it? That's torsion. Springs running along the left and right walls that look like they're getting longer and shorter? Those are extension springs.

Why Torsion Springs Cost More (But Last Longer)

Torsion springs typically cost more to replace than extension springs. A snapped torsion spring replacement runs higher because the design is more complex and requires precise balancing. Extension spring replacement is often cheaper upfront, but here's the catch: extension springs fail more frequently.

Torsion springs last 7 to 9 years on average with normal use. Extension springs often fail in 5 to 7 years. That means you'll replace extension springs more often over the life of your door. When you factor in labor and parts across multiple replacements, the economics shift.

If you're unsure about the actual cost in your situation, understand what factors shape your garage door springs estimate before calling anyone. Knowing your spring type helps you ask smarter questions.

Safety: Why Extension Springs Are Riskier

Extension springs carry a hidden danger. When they snap, they thrash around violently. Cables can whip free. If a cable breaks, the door can fall hard and fast, potentially injuring someone underneath or damaging a vehicle.

Torsion springs are safer by design. If they break, the door doesn't drop. You lose lifting assistance, but the door stays put. No snapping cables, no sudden collapse. That's why many jurisdictions now require safety cables on extension springs as a backup.

If you have extension springs, safety cables are non-negotiable. They cost little to install and prevent catastrophic failure. Think of them as insurance.

Which Type Do You Own? And Does It Matter for Repair?

Some homes have one spring type. Some have both, depending on the door design and age. Older homes in Concord often have extension springs. Newer construction leans toward torsion because they're safer and more durable.

When you call for service, tell the technician which type you have. If you're not sure, send a photo. Don't guess. Mixing up the types wastes time and can lead to incorrect diagnosis.

What to Do If One Breaks

If you hear a loud bang and your door won't open smoothly, stop using it. A snapped spring can't support the door properly. Forcing it up stresses the opener and risks injury.

Don't DIY spring replacement. Torsion springs especially are under extreme tension. Mishandling them causes serious injury. Read our guide on snapped springs for immediate next steps.

Springs don't last forever. But when you understand what you have and why it matters, you make smarter decisions about maintenance, repair, and replacement.

Frequently Asked Questions

Can I replace just one spring if I have two? Technically yes, but both springs wear at similar rates. Replacing both at once balances the door and prevents uneven stress. It costs slightly more upfront but saves a second service call within months.

How do I know if my spring is about to fail? Listen for squeaking or creaking. Watch for the door opening slowly or unevenly. If one side lifts faster than the other, spring tension is unbalanced. These are warnings. Don't wait for a snap.

Are extension springs with safety cables just as safe as torsion? Safety cables catch a snapped extension spring and prevent the door from falling. They're a critical backup, but torsion springs are still the safer design because failure itself is less violent.

What happens if I ignore a broken spring? The door becomes harder to open. The opener works overtime and can burn out. You risk dropping the door and damaging vehicles or property. Repair costs climb fast when you ignore the problem.

Do garage door springs come with a warranty? Most springs carry a manufacturer warranty covering defects. Labor is typically not covered. Ask your technician about what's included when springs are installed.
