Garage Door Spring Types in Winchester, NH: Torsion vs. Extension Explained
2026-09-04 7 min read
Here's what most homeowners don't realize about garage door springs: you probably have one of two types holding up that heavy door, and they work in completely different ways. After 15 years on the service trucks around Winchester, I've seen countless garage doors fail because the owner didn't understand which spring system they had or why it matters. This post breaks down torsion versus extension springs so you know exactly what's keeping your door balanced and what to do when one fails.
Torsion Springs: The Coiled Powerhouse Above Your Door
A torsion spring sits horizontally on a metal rod above your garage door opening. It's wound tight like a clock spring, storing mechanical energy that slowly releases as your door opens and closes. When you hit the opener button, that stored tension does most of the heavy lifting.
Torsion springs are the heavy hitter in modern garage doors. They're more durable, quieter, and distribute weight more evenly across the door. Most homes built in the last 20 years use torsion springs. They typically last 7 to 9 years with regular use, depending on how many times your door cycles daily.
The trade-off? They're more expensive to replace than extension springs, and installation requires specialized tools and real expertise. A snapped torsion spring can't be ignored for even a day. The door becomes unbalanced and puts strain on your opener motor.
Extension Springs: The Helpers on Both Sides
Extension springs hang vertically on either side of your door, alongside the tracks. When the door closes, these springs stretch out. When you open it, they contract and help lift the weight. Think of them like rubber bands doing assist work.
Extension springs are cheaper upfront and simpler to install, which is why older homes often have them. They're also easier to maintain yourself if you're handy. However, they wear out faster than torsion systems (usually 5 to 7 years) and require a safety cable running through the center of each spring. That cable catches the spring if it snaps, preventing it from whipping across your garage.
If an extension spring breaks, your door won't open smoothly, and one side may hang lower than the other. You'll notice the imbalance right away.

How to Know Which Type You Have
Stand inside your garage with the door closed and look above the door frame. See a horizontal metal rod with a coiled spring in the center? That's torsion. See two springs running up the sides of the door along the vertical tracks? Those are extension springs.
Not sure? Don't guess. A wrong diagnosis leads to wasted money and a door that still won't work. Our team can identify your system in seconds and recommend the right repair or replacement.
Why Springs Fail (And It's Not Always Age)
Springs fail because they're under constant tension. Every time your door opens and closes, the spring cycles. In a typical household, that's hundreds of cycles per year. After thousands of cycles, metal fatigues. Rust accelerates the process, especially in New England winters where salt and moisture are constant enemies.
Cold weather is particularly hard on springs. Metal contracts in freezing temperatures, making springs stiffer and more brittle. That's why we see more spring failures during January and February in Winchester and the surrounding region. If you haven't had your springs serviced recently, winter is the worst time to let them go.

What It Costs to Replace Springs in Winchester
Torsion spring replacement typically runs 300 to 600 dollars per spring, depending on the quality and size. Extension springs are cheaper, around 150 to 300 dollars each. But price isn't the main reason to choose one over the other. Your door was built for a specific system, and changing it usually isn't worth it.

Don't Ignore a Snapped Spring
A broken spring isn't a "wait until next month" problem. Your garage door opener will strain trying to lift a door it can't balance. That puts the motor at risk and can damage your entire system. More importantly, a garage door hanging on one side is a safety hazard for anyone underneath it.
If you suspect a broken spring, stop using your door and call for service immediately. Our emergency garage door service team responds quickly to spring failures across Winchester and nearby areas.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years, while extension springs last 5 to 7 years. Lifespan depends on usage frequency, climate, and maintenance. Regular lubrication extends life noticeably.
Can I replace a garage door spring myself? Extension springs can sometimes be replaced by experienced homeowners with the right tools. Torsion springs require professional installation due to high tension and injury risk. We recommend professional service for safety.
Why does my garage door move slowly? Slow movement often signals a weakening spring that's losing tension. The door opener works harder to compensate. This is a sign to schedule an inspection before the spring fails completely.
What's the difference between a broken spring and a stretched spring? A broken spring snaps completely, leaving two pieces. A stretched spring slowly loses tension over time, causing the door to sag or move unevenly. Both need replacement.
Is a snapped spring an emergency? Yes. Stop using your door immediately. A broken spring puts dangerous stress on your opener and creates a safety hazard. Contact a professional same-day service right away.
