Garage Door Springs in Medford: Torsion vs. Extension (And Why It Matters)
2026-07-01 7 min read A2Z Garage Doors
Here's what most homeowners don't realize about garage door springs: they're not all the same, and the type you have determines how much a replacement will cost and how long it lasts. Two main kinds exist: torsion springs and extension springs. Understanding which one your garage door uses can save you hundreds of dollars and prevent dangerous DIY attempts that end badly.
Torsion Springs vs. Extension Springs: What's the Difference?
Torsion springs sit horizontally above your garage door opening. They work by twisting (torque) to counterbalance the door's weight as it opens and closes. Extension springs run vertically along the sides of the door tracks. They stretch and contract like a rubber band, doing the same job in a different way.
Most modern homes in Medford use torsion springs because they're safer, last longer (typically 7 to 9 years with normal use), and distribute load more evenly. Extension springs are cheaper upfront but require safety cables running through their center. If an extension spring snaps, the cable catches it before it whips across your garage. That said, torsion springs are still the preferred choice for safety and longevity.
One critical detail: garage door springs are under extreme tension. A snapped spring isn't just a repair issue. It's a potential injury hazard. Even if you've replaced car parts or fixed home systems before, spring replacement isn't a homeowner DIY job. The tension can cause serious harm.
Why Springs Break and How to Spot Trouble Early
Garage door springs fail for predictable reasons. Rust and corrosion eat away at metal over time, especially in the Boston area where salt air and winter conditions accelerate wear. Repeated opening and closing cycles (springs go through roughly 10,000 to 20,000 cycles in their lifetime) eventually fatigue the metal. Poor maintenance speeds this along.
Warning signs appear before total failure. A door that's hard to open, moves unevenly, or makes loud creaking sounds often signals a weakening spring. If your door stays partially open or slams shut, don't ignore it. These aren't cosmetic issues. They mean your spring is losing strength and could fail completely within days or weeks.

Cost Reality: Torsion vs. Extension and Labor
A single torsion spring replacement typically runs between $150 and $400 per spring, depending on the spring's size and quality. Extension springs are slightly cheaper at $100 to $250 each, but most doors have two springs. Labor adds another $150 to $300 on top of parts.
The real budget trap? Waiting too long. A failing spring puts extra stress on your garage door opener, which then needs premature replacement (openers cost $300 to $600 installed). Regular maintenance catches weak springs before catastrophic failure occurs.
Our earlier post on garage door repair costs in Medford breaks down pricing in detail and explains why springs often break your budget. It's worth reading if you're weighing repair costs against your door's age.
Getting the Right Replacement and Avoiding Overspending
When a spring fails, you need a professional diagnosis. Different door weights and configurations require different spring specifications. A technician who measures your door, checks the spring constant, and verifies the opener's capacity ensures you get the correct replacement. Buying the wrong spring wastes money and creates safety problems.
Garage Door Medford handles this assessment at no charge. We'll schedule a free quote and same-day estimate to confirm what you need before committing to anything.
One more money-saving tip: if both springs are similar age and one snaps, replacing both at the same time costs less per spring than replacing one now and the other in six months. It's also smarter long term.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (about 10,000 to 20,000 opening cycles). Extension springs have a similar lifespan. Rust, lack of lubrication, and harsh weather can shorten this significantly.
Can I replace just one spring if both are old? Technically yes, but it's not smart. If one spring fails after years of use, the other is likely close behind. Replacing both at once costs less per spring and prevents a second failure within months.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly and leaves the door stuck or hanging unevenly. A worn spring gets weaker gradually, making the door harder to open or causing it to close too fast. Both require professional replacement.
Why can't I replace the spring myself? Springs are under 200 to 400 pounds of tension. A slip or mistake can cause the spring to whip violently, causing serious injury or death. Professional technicians use specialized tools and training to handle this safely.
How much does spring replacement cost near me in Medford? A single torsion spring costs $150 to $400 plus $150 to $300 in labor. Most doors have two springs. We offer free estimates and same-day service. Call 857-855-7892 for a quote.
