Torsion vs. Extension Springs in Pembroke, NH: Which Does Your Door Need?
7 min read
Your garage door won't open, and you're staring at a repair bill. Before you call anyone, you need to know one thing: which type of spring failed? Torsion and extension springs do the same job differently, and choosing the wrong replacement wastes money. Here's what Pembroke homeowners need to know to make the smart call.
How Garage Door Springs Work
Your garage door weighs 300 to 500 pounds. That's not something you want crashing down on your car or head. Springs counterbalance that weight, making the door light enough for your opener to lift safely.
Two spring types handle this job. Torsion springs sit above your door on a rod, twisting to store and release energy. Extension springs hang on either side of the door, stretching and contracting like a rubber band. Both wear out around the same time: 7 to 9 years with average use. But they fail differently, and that matters for your wallet.
Torsion Springs: The Stronger Choice
Torsion springs are the premium option. They're more durable, last longer, and balance your door more evenly. Most newer homes and quality installations use them. If your door opens smoothly and quietly, torsion springs are likely doing the work.
The trade-off? They cost more upfront. A single torsion spring runs $150 to $300, sometimes higher depending on your door's weight and size. But here's the budget-conscious angle: they rarely need adjustment, and a snapped torsion spring is easier to diagnose than an extension spring failure.
If you're unsure what you have, look above your garage door opening. See a metal rod with a spring wrapped around it? That's torsion. This setup is what Pembroke Garage Doors recommends for most homes because the long-term cost per year of operation comes out lower.
Extension Springs: The Budget Alternative
Extension springs are cheaper upfront, usually $75 to $150 each. They're common in older homes and budget installations. You'll find them mounted horizontally on both sides of the door track, and they're harder to balance correctly.
The catch: extension springs need more maintenance. They require cables and pulleys to work safely, and when one snaps, the other is usually close behind. You often end up replacing both at once, which cancels out the initial savings. Plus, if a cable breaks, your door can drop suddenly, creating a serious safety hazard.

How to Identify Your Spring Type
Look at your garage door opening from the inside. If you see one metal rod running horizontally above the door with a coiled spring around it, you have torsion. If you see two springs hanging vertically on the left and right sides of the door tracks, those are extensions.

Replacement Cost Breakdown
Beyond the spring itself, labor matters. Torsion spring replacement takes 1.5 to 2 hours and runs $200 to $400 for labor. Extension springs take longer if both need replacing, pushing labor to $300 to $500. Our honest breakdown of garage door costs in Pembroke covers pricing in depth, including what you should expect to pay regionally.
The real money saver? Don't wait. A single snapped spring forces you to replace both because the working spring is near the end of its life. Replacing both at once costs maybe $100 to $150 more than one, but the inconvenience and risk of the second failing soon after makes it the smarter choice upfront.
When to Call a Professional
Replacing garage door springs is dangerous. Springs are under extreme tension, and a slip can cause serious injury. This isn't a DIY project. Don't try it.
Call Pembroke Garage Doors or another licensed technician for professional spring replacement and same-day service options. The $200 to $400 labor cost is cheap insurance against a trip to the emergency room.
What to Do Right Now
If your door won't open or you hear a loud snap, stop using it. Don't force the opener. A broken spring means zero counterbalance, and pushing the system can damage the opener or door panels.

Frequently Asked Questions
Can I replace just one spring if the other is still working? Technically yes, but it's poor planning. Both springs are the same age and near failure. Replacing one now means a second emergency call within months. Replace both at once and avoid the hassle.
How long do garage door springs actually last? Torsion and extension springs typically last 7 to 9 years with normal residential use, about 10,000 cycles. Heavy use or extreme New England weather can shorten this.
Is torsion always better than extension springs? For most homes, yes. Torsion springs are safer, more balanced, and require less maintenance. Extension springs work fine in budget situations but need more upkeep and often fail in pairs.
What's the difference in cost between torsion and extension replacement? Torsion costs $350 to $700 installed, extension costs $250 to $400. The upfront savings of extension springs evaporate when you replace both at once, making torsion the smarter long-term choice.
Should I replace my garage door if the springs fail? Not usually. A door with good panels and a working opener just needs new springs. Full replacement is rarely necessary unless the door itself is damaged. Check our guide on repair versus replacement decisions for damaged panels.
