Garage Door Springs in Thomaston: Torsion vs. Extension (And Real Costs)
2026-08-29 7 min read
Your garage door springs are under massive tension, holding roughly half your door's weight at any moment. When one snaps, your door becomes a safety hazard and a costly headache. Let's cut through the confusion: torsion springs sit above your door and twist to lift it, while extension springs run along the sides and stretch. Most Thomaston homes use torsion springs. Both fail eventually. The real question is knowing when yours will go and what it costs to fix.
Why Garage Door Springs Fail (And When)
Springs don't just break randomly. They're engineered to open and close your door roughly 10,000 to 15,000 times before wearing out. That's 7 to 9 years for the average household. Cold Thomaston winters accelerate wear because metal becomes brittle in low temperatures. Humidity and rust speed up failure too.
A snapped spring feels dramatic. Your door may hang crooked, refuse to open, or fall hard when the opener tries lifting it. Don't force it. That's a recipe for damaging the opener, cables, or your car parked underneath.
Torsion Springs: The Standard Choice
Torsion springs are the industry standard in residential garages. One or two springs sit on a horizontal rod above your door. When you press the opener button, the spring twists (torsion is the mechanical term) and unwinds slowly, letting the cable system lower the door smoothly.
Why torsion? They're safer, quieter, and last longer than extension springs. They also balance your door better, reducing strain on the opener motor. If you have an older home in Thomaston with extension springs, many homeowners upgrade to torsion during replacement because the durability difference is real.
Torsion springs cost more upfront. You're looking at $150 to $300 per spring, plus labor. A two-spring system (common in heavier doors) runs $300 to $600 in parts alone. That's honest pricing, and we've laid out the full breakdown before in our garage door cost and pricing guide.
Extension Springs: Budget Option With Tradeoffs
Extension springs hang vertically on each side of your door frame. When the door rises, they stretch. When it falls, they contract and help slow the descent. They're cheaper than torsion springs (usually $75 to $150 each) but wear out faster and carry more safety risk.
Why? If an extension spring snaps, the cable can whip around. That's dangerous. Extension springs also require safety cables running through the center of the spring to catch it if it fails. These cables add cost and maintenance complexity.
If you own an older home with extension springs and they're still working, replacement doesn't demand an immediate upgrade to torsion. But if you're replacing them anyway, torsion is the smarter long-term investment. You'll get better door balance, fewer future repairs, and better resale value for your home.

What Does Spring Replacement Actually Cost?
This is where honest pricing matters. A snapped spring replacement in Thomaston typically runs $250 to $500 total, depending on whether you have one or two springs and which type.
Here's the breakdown: - Single torsion spring replacement: $250 to $350, Dual torsion spring replacement: $400 to $550, Extension spring replacement (per spring): $150 to $250, Labor: included in the above; most jobs take 1 to 2 hours
Prices vary based on door size, spring gauge (thickness), and whether cables need replacement too. A snapped spring often means worn cables are next. Replacing both at once prevents a second service call weeks later.

Spring Failure in Winter: A Thomaston Problem
Connecticut winters hit hard. Temperatures drop, metal contracts, and springs that were barely holding on suddenly snap. This is why we offer emergency garage door service after hours in Thomaston. Winter mornings are peak failure season.
If your door won't open in January, don't wait. A stuck garage door can trap your car and disrupt your whole day. Same-day service isn't a luxury in winter; it's practical.
When to Replace vs. Repair
If only one spring snapped and the other is original, you have a choice. You can replace just the broken one (cheapest now, but the other fails in months). Or replace both at once (higher cost, but 7 to 9 more years of reliability). Most homeowners choose to replace both. The second spring is already near end of life, and labor is the expensive part anyway.

Frequently Asked Questions
How long do garage door springs last? Most springs last 7 to 9 years with normal use (roughly 10,000 to 15,000 open-close cycles). Cold winters and humidity can shorten lifespan. Torsion springs typically outlast extension springs by 2 to 3 years.
Can I open my garage door if a spring is broken? Not safely. A snapped spring removes half the lifting force. Your opener will struggle, the door may fall suddenly, and you risk damaging the motor. Call a technician instead of forcing it.
Is it better to replace one spring or both? Replace both if they're original. One spring snapping means the other is near failure anyway. Paying for labor twice in a few months costs more than replacing both now. It's the smarter long-term choice.
What's the difference between torsion and extension springs? Torsion springs twist above your door and are safer, quieter, and last longer. Extension springs stretch on the sides and are cheaper but wear faster and carry higher safety risk if they snap.
How much does spring replacement cost in Thomaston? Single torsion spring: $250 to $350. Dual torsion springs: $400 to $550. Extension springs cost less but fail sooner. Exact price depends on door size and whether cables need replacement too.
