Garage Door Spring Types in Devens: Torsion vs. Extension Explained
2026-06-22 7 min read
If you've ever dealt with a stuck garage door that won't budge, there's a good chance your spring has failed. Two types of springs power residential garage doors: torsion springs (wound around a shaft above the door) and extension springs (running along the sides). Understanding which one you have helps you recognize problems faster and avoid costly repairs down the road.
What Are Torsion Springs?
Torsion springs sit horizontally on a metal rod above your garage door opening. They wind up like a clock spring, storing energy as your door closes. When you press the opener button, that stored energy unwinds to lift the heavy door. Most modern homes in Devens and surrounding areas use torsion springs because they're smoother, quieter, and last longer than their counterparts. See our guide on budget-friendly options: making smart decisions.
A typical torsion spring lasts 7 to 9 years with normal use. The lifespan depends on how often you open and close your door (most manufacturers rate springs at around 10,000 cycles). When a torsion spring snaps, the door suddenly feels heavier, or won't open at all. You'll hear a loud bang when it breaks, which can startle you. Never try to manually lift a door with a broken torsion spring. The weight becomes unbalanced and dangerous.
What Are Extension Springs?
Extension springs work differently. They're mounted on each side of the door, running parallel to the horizontal tracks. As the door closes, these springs stretch and store energy. When you open the door, they contract and help lift it. Older homes often have extension springs, though some newer installations still use them in budget scenarios.

Extension springs typically last 5 to 7 years. They're more prone to wear because they're exposed to more movement and friction. A snapped extension spring shows similar symptoms to a broken torsion spring: the door feels heavy or won't open smoothly. One key difference is that you can sometimes see the broken coil hanging loose inside the track.
Safety cables run alongside extension springs specifically to catch a snapping spring before it whips across your garage. This is critical because a failing extension spring can cause serious injury. If you suspect an extension spring problem, avoid using your door and schedule a free quote) with a professional right away.

Why Springs Fail: Common Causes
Springs break for predictable reasons. Rust and corrosion weaken metal over time, especially in New England's humid climate. Lack of lubrication increases friction and accelerates wear. Temperature swings in winter can make steel brittle. And simple age does its job: springs have a finite lifespan measured in cycles, not just years.
You can extend spring life with basic maintenance. Apply a light garage door lubricant (not WD-40, which attracts dust) to the springs and hinges twice a year. Keep the door tracks clean. Check for visible rust or fraying. If you notice squeaking or creaking sounds during operation, that's often an early warning sign.

Repair vs. Replacement: What's the Cost?
Garage door spring repair isn't a DIY job. Springs are under extreme tension and can cause serious injury if mishandled. Professional replacement is the safe, smart choice.
At Devens Garage Doors, we're upfront about pricing. A torsion spring replacement typically costs less than an extension spring replacement because torsion springs are more common and easier to install. Both types usually require same-day service if you want your door working again. We'll give you a clear estimate before we start work, with no hidden fees.
If both springs have failed (which sometimes happens), replacing both at once is actually more cost-effective than staggering repairs. One spring will put extra stress on the remaining spring, causing it to fail sooner. Check our detailed spring cost breakdown) to understand pricing better.
How to Know Which Type You Have
Look above your garage door. If you see a horizontal metal rod with a spring wound around it, you have torsion. If you see springs running up the sides of the door frame, you have extension springs. When in doubt, take a photo and call us. We can identify your system immediately and provide our full spring replacement services).
Don't wait for a spring to snap unexpectedly. Proactive replacement when springs reach 7 to 9 years old prevents emergency situations and keeps your family safe.

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, maintenance, and climate. Springs rated at 10,000 cycles may fail sooner if your door opens and closes multiple times daily.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if mishandled. Always hire a licensed professional. DIY attempts void warranties and create liability risks. Call a qualified technician for safe, reliable replacement.
What's the difference in cost between torsion and extension springs? Torsion springs usually cost less to replace because they're more common and easier to install. Extension springs require more labor. Exact pricing depends on your specific system, but expect torsion replacements to be 15 to 25 percent less expensive.
Why did my spring break suddenly? Springs weaken gradually over years due to rust, friction, temperature changes, and metal fatigue. The actual break feels sudden, but the spring was already near failure. Regular maintenance and lubrication slow this process and help you catch problems early.
Do I need to replace both springs at once? Yes, if both have failed or are very old. Replacing one puts extra stress on the remaining spring, shortening its life. Replacing both at the same time is more cost-effective and prevents a second failure weeks later.
