Garage Door Torsion vs. Extension Springs in Carlton: Which Fails First?
2026-08-04 7 min read A2Z Garage Doors
In our years serving Carlton and surrounding areas, we've seen this problem again and again: homeowners confuse their spring type, miss early warning signs, and end up facing a snapped spring at the worst possible moment. Torsion and extension springs work differently, fail at different rates, and cost different amounts to replace. Understanding which one you have could save you money and prevent a dangerous emergency.
What's the Difference Between Torsion and Extension Springs?
Your garage door weighs 300 to 500 pounds. Two springs do the heavy lifting to open and close it safely. The type of spring you have determines how that weight gets balanced.
Torsion springs sit horizontally above your door. They twist and unwind, using torque to counterbalance the weight. One spring can often handle the entire load. Torsion springs are mounted on a steel shaft that runs across the top of the opening.
Extension springs hang vertically on each side of the door. They stretch and contract like shock absorbers, working in pairs to lift the weight. You'll see them along the left and right tracks, usually with a cable running through the middle of each spring.
Most modern homes in Carlton use torsion springs because they're safer and last longer. Older installations commonly used extension springs. If you're not sure which you have, learn the warning signs before they snap and call us for a free inspection.
Why Torsion Springs Last Longer (But Cost More to Replace)
Torsion springs typically last 7 to 9 years with normal use. Extension springs last 5 to 7 years. The difference comes down to stress distribution and wear patterns.
A single torsion spring bears concentrated stress in a controlled rotation. Because the load is balanced and consistent, the metal degrades more slowly. When a torsion spring does snap, the sound is unmistakable: a loud BANG that echoes through your garage.
Extension springs wear out faster because they stretch and contract thousands of times. Each cycle creates micro-fractures in the metal. When one extension spring fails, the other side often fails within weeks because the door becomes unbalanced. We've responded to countless calls where a homeowner ignored one broken extension spring, only to have the second one snap days later.

The trade-off: torsion springs cost more upfront (typically $200 to $300 per spring installed), but you replace them less often. Extension springs cost $100 to $150 per spring, but you'll buy them more frequently. Over 20 years, torsion springs save most homeowners money.
Which One Is More Dangerous?
This matters. Extension springs can snap with violent force. When they break, the metal whips sideways, and the door can drop suddenly. We've seen injuries from extension spring failures that could have been prevented with regular inspection.
Torsion springs fail less often, but when they do, the failure is still catastrophic. The door becomes a 400-pound dead weight. A malfunctioning opener can't lift it, and you're stuck.
Both require professional replacement. Don't attempt this yourself. Spring tension is lethal. We've seen amateur repairs go wrong, and the results are serious injuries or worse.
The Cost Reality for Carlton Homeowners
Here's where clarity matters. If you need a same-day estimate for spring replacement cost, expect to pay:
Torsion spring replacement: $250 to $350 per spring, plus labor. Extension spring replacement: $150 to $250 per spring, plus labor. Labor typically adds $100 to $200 per visit.
If both springs need replacement (common with extension springs), budget $400 to $800 total. Torsion systems cost $500 to $1000 for both springs.
Preventive maintenance costs less than emergency repair. Schedule your annual tune-up to catch wear before it becomes a crisis.
What to Do Right Now
Check your garage door springs today. Open your garage door manually (if it's safe) and look up. Do you see a horizontal coiled spring above the door? That's torsion. Do you see springs hanging down the sides? That's extension.
If your door is hard to open, makes grinding noises, or won't stay open on its own, don't wait. Contact Garage Door Carlton's spring repair services for a diagnosis.
A snapped spring won't fix itself. Waiting only increases the risk of secondary damage to your opener, door panels, and cables. Same-day repairs are available when you call us early.
Call (971) 265-6680 or schedule a free estimate online. We'll identify your spring type, assess remaining lifespan, and give you honest pricing before any work begins.
Frequently Asked Questions
How do I know if my spring is about to snap? Look for gaps in the coil, visible rust or corrosion, and listen for creaking or popping sounds during operation. A door that feels heavier than usual is also a red flag. We recommend annual inspection to catch these signs early.
Can I replace just one spring if I have two? With torsion springs, yes. With extension springs, no. Extension springs wear as a pair, so both should be replaced together to avoid imbalance and premature failure of the remaining spring.
How long does spring replacement take? Typically 1 to 2 hours depending on spring type and door condition. We handle most replacements within a single service call, and you can use your door immediately after.
Is spring replacement covered by homeowner's insurance? Rarely. Most policies don't cover wear and tear on garage door components. Check your policy, but plan to cover this cost out of pocket. Review long-term cost benefits of upgrading to torsion if you have extension springs.
What happens if I ignore a snapped spring? Your door becomes unsafe to operate. The opener works harder and may burn out. Secondary damage spreads to cables, rollers, and panels. Emergency service becomes necessary, and costs multiply. Replace springs promptly.
