If you've ever had a garage door that wouldn't budge, there's a good chance a spring problem was to blame. But not all springs are created equal. Understanding whether your door uses torsion or extension springs matters for repair costs, safety, and how quickly we can get you back in business.
Your garage door weighs 300 to 500 pounds. It doesn't lift itself. Two heavy-duty springs do that work, and they're under tremendous tension. When you press the remote, those springs counterbalance the door's weight, making the opener's job manageable. Without them, your 400-pound door would crash down like a guillotine.
Springs are the hardest-working part of your garage door system. They cycle thousands of times over their lifespan. Most quality springs last 7 to 9 years with regular use, though that timeline depends on how often you open and close the door.
Torsion springs sit horizontally above your garage door opening, mounted on a metal shaft. They twist and unwind to lift the door. Think of a clock spring, but industrial-grade.
Here's why homeowners in Chatham and across Cape Cod see these most often: they're smoother, quieter, and safer than their counterparts. When a torsion spring fails, the door doesn't suddenly drop. Instead, it descends slowly or gets stuck partway up. That's a safety advantage.
A snapped spring means the shaft will spin freely without resistance. You'll hear a loud bang. Don't try lifting the door manually. Call us for same-day service.
Torsion springs are precision-engineered. They're custom-wound to your door's exact weight and height. A replacement typically runs $150 to $300 per spring, depending on the door size and spring quality. Installation adds another $100 to $200. We never hide those numbers. You'll get an honest estimate before we touch anything.
Extension springs run horizontally along each side of the door opening, above the horizontal tracks. They stretch and contract as the door moves. When fully extended, they're under severe tension.
These cost less upfront, usually $75 to $150 per spring plus labor. But extension springs come with a trade-off: they're more prone to sudden failure. When one snaps, the other can't handle the load alone, and the door becomes unbalanced.
Extension springs also need safety cables. Without them, a snapped spring can whip across your garage with enough force to cause serious injury. That's not fear-mongering. It's physics.

Stand in your garage and look at the space directly above the door. If you see a horizontal shaft with springs coiled around it, you have torsion. If you see springs running along the tracks on both sides, you have extension springs.

How long do garage door springs last? Quality torsion and extension springs last 7 to 9 years with normal residential use. Heavy use or extreme weather (like salt air on Cape Cod) can shorten that timeline. Regular lubrication and inspection help maximize lifespan.
Can I replace one spring if the other is fine? We recommend replacing both springs at the same time, even if only one failed. The working spring is the same age and under equal stress. Replacing both ensures balanced performance and prevents a second failure weeks later.
What's the difference in price between torsion and extension? Torsion springs typically cost $300 to $500 installed. Extension springs run $200 to $350. Torsion costs more upfront but offers better longevity, smoother operation, and superior safety features.
How do I know my spring is broken? A snapped spring produces a loud bang and the door becomes very heavy or won't open at all. You might also notice the door closing too fast or stopping partway up. Call immediately. Don't attempt to open it manually.
Is garage door spring repair covered by warranty? Most springs carry a 1 to 5 year warranty depending on manufacturer and quality tier. We explain warranty details in every estimate. Ask us about our preferred brands and their coverage.
