Garage Door Springs in Westport: Torsion vs. Extension (Which Fails First?)
2026-08-14 7 min read
After 15 years on garage door calls across Westport and neighboring Darien, I've learned that most homeowners don't understand their springs until one snaps. Let me cut through the confusion about garage door springs. Your door relies on one of two spring types: torsion or extension. Knowing which you have, how long they last, and what to expect when they fail could save you time, money, and a stuck car in the driveway.
How Torsion and Extension Springs Work
The two systems handle the weight of your door in completely different ways.
Torsion springs sit above your garage door, running horizontally across a metal rod. They twist and unwind as your door opens and closes, slowly releasing stored energy. These are the workhorses. Most modern homes in Westport built after 1990 have torsion springs because they're smoother, safer, and more reliable.
Extension springs hang vertically on both sides of your door track. They stretch and contract like a rubber band. Older homes often still use extension springs. When one snaps, your door can feel heavy or unbalanced immediately.
Why This Matters for Safety
Torsion springs store enormous tension. A snapped spring won't drop your door, but it removes the mechanical advantage your opener needs. Your motor works harder. Extension springs, by contrast, can snap with dramatic force. I've seen them launch across a garage. This is why the garage door safety post I wrote earlier covers spring hazards.
How Long Do Garage Door Springs Last?
Torsion and extension springs last roughly 7 to 9 years under normal conditions. Some manufacturers claim 10,000 to 15,000 cycles. One cycle equals one complete open-and-close. If you use your door four times daily, you're looking at about seven years before replacement becomes necessary.
Several factors speed up wear. Salt air in coastal Connecticut accelerates rust. Humidity and temperature swings stress the metal. Heavy use drains the lifespan faster. If you operate your garage door more than six times daily, plan on replacing springs closer to five years instead of nine.
I recommend scheduling a spring maintenance checkup annually, especially as springs approach the five-year mark.

Signs Your Springs Are About to Fail
A snapped spring never announces itself politely. But the warning signs are clear if you know what to look for.
Listen for a loud metallic bang or crack. That's the sound of a snapped spring, and it happens fast. Your door will feel heavier than usual when you try to open it manually. The opener might struggle or make unusual grinding noises. You might notice the door opening slowly on one side, or it tilts slightly.
If your door won't open at all and the opener is humming, springs are the most likely culprit. Don't force it. A garage door without functioning springs can drop suddenly.
Visual inspection helps too. Look above your door. Torsion springs should be intact and centered. Extension springs should appear smooth without visible gaps or separation. Rust spots indicate moisture damage and faster failure. If you spot rust or hear creaking, contact us for a free estimate.
The Real Cost of a Snapped Spring in Westport
Spring replacement cost varies based on your system and local pricing. A single torsion spring typically runs $150 to $300 in parts and labor. Extension springs cost $100 to $200 per spring. Most doors have two extension springs or one torsion spring, so the total bill depends on your setup.
For detailed pricing in your area, I wrote a comprehensive guide on garage door repair costs in Westport. It breaks down what you'll actually pay versus hidden fees.
Labor is usually the bigger expense. Replacing springs requires specialized tools and knowledge. This isn't a DIY job. A stretched or improperly installed spring can cause injury or damage your opener. Call a licensed technician. We at Garage Door Company Westport offer same-day estimates and service whenever possible.

Frequently Asked Questions
What's the difference between torsion and extension springs? Torsion springs twist horizontally above the door, storing energy in coils. Extension springs hang vertically, stretching like rubber bands. Torsion is safer, more modern, and lasts longer under stress. Most newer homes use torsion; older homes often use extension springs.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if mishandled. Improper installation also damages your opener and door. Always hire a licensed technician with proper tools and insurance coverage.
How much does spring replacement cost? Single torsion springs cost $150 to $300 installed. Extension springs run $100 to $200 each. Most doors need one torsion or two extension springs. Call us at 203-945-1127 for a same-day estimate.
Why did my spring snap without warning? Springs degrade silently over years. Rust, temperature swings, and heavy use accelerate wear. Annual maintenance catches problems early. Regular lubrication and inspection can extend spring life by years.
How often should I replace garage door springs? Most springs last 7 to 9 years with normal use (four open-close cycles daily). Higher use requires earlier replacement. Schedule maintenance annually to monitor wear and catch issues before failure.
