In our years serving Leicester, we've seen this problem again and again: homeowners don't know the difference between extension and torsion springs until one snaps. The repair cost depends entirely on which type you have, and that's where most people overpay. Understanding the difference now could save you hundreds.
Your garage door weighs 300 to 500 pounds. Two small springs do the heavy lifting, and they work in completely different ways.
Extension springs run along the sides of your door frame. They stretch and contract like a rubber band as your door opens and closes. Torsion springs sit above the door on a horizontal rod. They twist and unwind to handle the weight.
Most homes in the Leicester area use one or the other, rarely both. Which type you have determines repair cost, lifespan, and replacement complexity.
Extension springs typically cost $150 to $250 per spring to replace, including labor. They're the budget-friendly option upfront. However, they carry a hidden danger.
When an extension spring snaps, the broken coil can whip around or fall. This poses a genuine safety risk to anyone nearby. If you have kids or pets, this matters. A snapped spring also means your door won't open or close smoothly, and you'll struggle to operate it manually.
Extension springs last 7 to 9 years on average. They wear faster than torsion springs because they're under constant tension. If your door is already over eight years old and you've never replaced the springs, you're on borrowed time.
The good news: a same-day estimate near you is usually quick to arrange, and replacement takes 1 to 2 hours.
Torsion springs run $200 to $400 per spring, sometimes more. Installation is also pricier because the job requires specialized tools and expertise. The rod they sit on is under extreme torque, and mishandling it can cause serious injury.
That said, torsion springs outlast extension springs by 3 to 5 years. They're engineered to handle wear more evenly and fail less suddenly. When a torsion spring does fail, your door typically won't fall or slam unexpectedly, which is safer.
Over the lifespan of your garage door, paying more upfront for torsion springs often saves money. You'll replace them fewer times.

Stand in your garage and look above the door. If you see a long metal rod running horizontally with springs coiled around it, you have torsion springs. If you see springs running vertically along each side of the frame, those are extension springs.
Don't attempt to inspect or touch either type yourself. Springs are under extreme tension and can cause serious injury if disturbed. Call a professional for a free visual diagnosis.
Here's where budget matters. If you're comparing total cost of ownership over 15 years:
Two extension springs: $300 to $500 now, likely replaced again in 8 years (another $300 to $500), plus potential safety incidents. Total: $600 to $1,000 plus risk.
Two torsion springs: $400 to $800 now, possibly one replacement in 12 years (another $400 to $800). Total: $800 to $1,600 but far fewer service calls.
Extension springs cost less per repair. Torsion springs cost less over time. Your choice depends on how long you plan to stay in your home.
A snapped spring doesn't fix itself. Your garage door becomes inoperable. You can't park safely, and you lose weather protection. Emergency service calls cost 20% to 40% more than scheduled repairs. One snapped spring often means the other will follow within weeks, so most techs recommend replacing both at once.

When you call for a quote, ask whether your door uses extension or torsion springs. Then ask for the cost per spring plus labor. Beware estimates that lump everything together without itemizing. A professional should also inspect your door's overall condition and let you know if anything else needs attention.
Get a same-day estimate from Garage Door Leicester to compare your options without pressure. We'll tell you exactly which type you have and what replacement really costs.
Can I replace just one spring? No. Springs work in pairs and age together. Replacing only one creates imbalance and causes the door to bind or fail prematurely. Always replace both at the same time.
How do I know if a spring is about to snap? Listen for squeaking or creaking sounds during operation. Watch for uneven door movement. If the door feels heavier than usual, a spring may be weakening. Don't wait for a break to call for service.
Is it safe to manually open my garage door if the spring is broken? Extension spring failure makes manual operation difficult and potentially dangerous. Torsion spring failure may allow the door to drop suddenly. Call a professional instead of forcing it open yourself.
Which spring type lasts longer? Torsion springs typically last 12 to 15 years, while extension springs last 7 to 9 years. Both depend on usage frequency and maintenance. For more information, see our comprehensive guide to garage door spring lifespan.
