Garage Door Springs in Darien: Torsion vs. Extension (Which Do You Have?)
2026-06-28
Your garage door relies on one of two spring systems to lift a 300-400 pound door smoothly. Torsion springs twist above the door, while extension springs stretch on either side. If you don't know which type you have, you can't judge when replacement is needed or why a snapped spring demands immediate attention. In our years serving Darien, we've seen homeowners delay repairs because they simply didn't understand their own system.
Torsion Springs: The Workhorse
Torsion springs mount horizontally on a metal rod above your garage door opening. When the door closes, these springs wind up tightly, storing mechanical energy. As your opener signals the lift, that stored energy unwinds, counterbalancing the door's weight and making the opener's job effortless. See our guide on how often should you maintain your garage door in darien?.
A quality torsion spring lasts 7 to 9 years under normal use (roughly 10,000 door cycles). Once one snaps, the other isn't far behind. Both should be replaced together, even if only one has failed. This prevents imbalance and uneven stress on your opener and tracks.
Torsion springs are safer than their counterparts because the coils remain contained on the rod. If a spring breaks, parts stay mostly in place. They're also more compact and suited to narrow garage openings, making them the standard in newer homes and commercial applications.

The downside: torsion springs cost more upfront but deliver longer lifespan and better performance. Replacement requires specialized tools and knowledge. Never attempt this yourself. A snapped torsion spring stores explosive tension that can cause serious injury.
Extension Springs: Older but Still Common
Extension springs hang vertically on each side of the door, parallel to the tracks. When the door closes, these springs stretch. When it opens, they contract and help lift the load. You'll often see safety cables running through the center of each spring.
These springs also wear out after 7 to 9 years, though some fail sooner depending on usage and maintenance. Unlike torsion springs, extension springs can fail one at a time without immediately affecting the other. However, replacing both at once ensures balanced operation and prevents future callouts.
The real danger with extension springs is catastrophic failure. If a spring snaps, the cable holding it may not catch the spring in time, sending coils flying across your garage. This is why those safety cables exist. Check them regularly and have them inspected during routine maintenance visits.

How to Tell Which Type You Have
Look above your garage door from inside the garage. If you see a tightly wound horizontal coil on a rod above the door frame, you have torsion springs. If you see two long vertical springs running alongside the door tracks (one on each side), you have extension springs.
This matters because repair costs, safety risks, and replacement timelines differ. An extension spring snapped in Stamford or Darien responds differently than a torsion failure. Both need professional attention, but the urgency and process vary.
Why This Matters for Your Next Repair

Frequently Asked Questions
How long do garage door springs last? Both torsion and extension springs typically last 7 to 9 years, or about 10,000 door cycles. Life expectancy depends on usage frequency, climate, and maintenance. Harsh Connecticut winters can accelerate wear.
Can I replace just one spring? Technically yes, but both springs should be replaced together. A new spring paired with an aged one creates imbalance, stressing your opener and tracks unevenly. Replacing both at once costs more upfront but saves money long-term.
What's the cost difference between spring types? Torsion springs generally cost more due to longer lifespan and precision installation requirements. Extension springs cost less but may need replacement sooner. Labor and materials typically range from $300 to $600 per spring.
Is a snapped spring an emergency? Yes. Stop using your garage door immediately. A broken spring forces your opener to work harder, risking further damage and safety hazards. Call a professional for same-day replacement.
How do I know if my springs are failing? Watch for uneven door movement, loud bangs or pops, slow opening, or visible rust and fraying. If you notice these signs, don't delay. Spring failure is predictable but can turn dangerous fast.
