Torsion vs. Extension Springs in Epping: Which Does Your Door Need?
2026-08-21 7 min read
Here's what most homeowners don't realize about garage door springs: not all springs are created equal. Your door likely uses either a torsion spring or an extension spring, and the two operate in completely different ways. Mix them up during replacement, and you're looking at a door that won't open smoothly, won't close safely, or worse, a snapped spring that leaves you stranded. I've been running Garage Door Epping for years, and this confusion costs people real money.
The Core Difference: How Each Spring Works
Torsion springs sit horizontally above your garage door, wound tightly like a clock spring. They twist and unwind to lift the door's weight. Extension springs hang vertically on either side of the door frame and stretch to pull the door open. The setup depends on your door's size, weight, and garage layout.
Torsion springs are stronger and last longer. They distribute weight more evenly and handle repeated cycles better. Most modern homes in Epping use torsion because they're reliable and safer. Extension springs are cheaper upfront but wear out faster, typically lasting 7 to 9 years instead of torsion's 10 to 15 year lifespan.
Identifying Which Type You Have
Walk into your garage and look up. If you see a single coiled spring running horizontally across the top of the door opening, you have torsion. If you see two springs running up and down the sides of the frame (one on each side), those are extension springs.
This matters because a snapped spring means no DIY fix. The door becomes a two-ton dead weight. You need professional help, and fast. If you're unsure what you're looking at, snap a photo and call us for a free estimate before anything breaks.

Why Spring Choice Affects Your Wallet
Extension springs cost less to replace, usually running $150 to $300 per pair. Torsion springs run $200 to $400 depending on size and quality. But here's the real math: torsion springs last 1.5 times longer and put less strain on your garage door opener motor. Over a decade, you're spending less overall.
We've written extensively about garage door springs cost in Epping for this reason. Most homeowners fixate on the initial bill and miss the bigger picture. A cheap extension spring replacement saves $100 today but costs $150 more in opener wear and tear over five years.
Safety Considerations You Can't Ignore
This is where I get serious. Extension springs use safety cables running through the center of the spring. If the spring snaps, the cable catches it and keeps the spring from flying across your garage. Torsion springs don't need cables because the spring is contained above the door, but they're under extreme tension. Never touch a wound torsion spring yourself. The stored energy can cause serious injury.

When to Replace Versus Repair
Springs don't get "repaired." They get replaced. Once a spring snaps or weakens, it's done. The only choice is whether to replace one spring or both.
If your door is older and one spring breaks, I recommend replacing both. Springs wear together. The remaining spring picked up most of the work and is close behind the broken one. Replace just one, and the other fails in weeks. You're paying the service call twice for barely more investment.

Regional Considerations for North Shore Homeowners
Epping winters mean temperature swings. Cold makes springs more brittle. Salt air near the coast corrodes springs faster than inland locations. If you're between Epping and the North Shore, springs may fail sooner than the national average. This is another reason I lean toward torsion and quality brands for customers in this area.

Frequently Asked Questions
What's the average cost to replace a torsion spring in Epping? Torsion spring replacement typically costs $250 to $450 including labor, depending on spring size and door weight. Heavier doors need stronger (more expensive) springs. Always replace both springs even if one breaks.
Can I replace a garage door spring myself? No. Garage door springs are under 200+ pounds of tension. Improper handling causes serious injury or death. Always hire a licensed technician. The service call is cheaper than an emergency room visit.
How long do garage door springs last? Torsion springs last 10 to 15 years with normal use (about 3 to 5 cycles per day). Extension springs last 7 to 9 years. Harsh weather and frequent cycling reduce lifespan. Regular maintenance helps.
What happens when a garage door spring snaps? The door won't open or close. It becomes extremely heavy. The opener motor may burn out trying to lift it. Extension spring safety cables may prevent flying debris. Never force the door. Call a professional immediately.
Are torsion springs worth the extra cost? Yes. Torsion springs last longer, handle heavier doors better, and put less strain on your opener. Over a decade, you save money and headaches despite higher initial cost. Worth it for most homeowners.
