Torsion vs. Extension Springs in New Britain: Which Does Your Door Need?
2026-08-25 7 min read
In our years serving New Britain, we've seen this problem again and again: homeowners don't realize there are two completely different types of garage door springs, and picking the wrong one leads to costly repairs or safety hazards. Torsion springs and extension springs work differently, cost differently, and last different lengths of time. Understanding which one your door uses (and why) protects your wallet and your family.
The Two Spring Types: Torsion vs. Extension
Your garage door weighs between 300 and 500 pounds. That weight needs to be balanced so your opener doesn't burn out and you don't risk the door crashing down. Springs do that balancing work, but in two different ways.
Torsion springs are mounted horizontally above your garage door opening on a metal shaft. They twist (or torque) as the door moves, storing and releasing energy like a wound clock. Most modern homes built in the last 30 years use torsion springs. They're safer, more durable, and more predictable than their older cousin.
Extension springs hang vertically on each side of your door opening. They stretch as the door lowers and contract as it rises. Older homes in New Britain and the surrounding area often have extension springs. You'll see them connected to pulleys and cables running along the sides of the opening.
The key difference: torsion springs contain the energy between the door and the walls. Extension springs are exposed and under constant tension, which means a snapped spring can whip around dangerously.
Why Type Matters for Cost and Safety
If your door currently has extension springs and you're shopping for a replacement, don't assume you need the same type. Many homeowners upgrade to torsion springs because they offer better balance, fewer moving parts, and less wear on your garage door opener over time.
Torsion springs typically last 7 to 9 years with normal use. Extension springs usually give you 5 to 7 years. Both depend on how often you open and close the door, climate conditions in Connecticut, and whether you keep up with lubrication and maintenance.
A snapped spring isn't something you fix yourself, no matter the type. We've written before about what to do when a spring breaks suddenly, but the short answer is: stop using your door and call a professional immediately. A broken spring can't support the door's weight, and the opener will strain trying to lift it.

How to Know Which Type You Have
Walk into your garage and look straight up at the space above your door. If you see a long metal shaft running horizontally with coils wrapped around it, you have torsion springs. If you see springs hanging down the sides of the opening with cables attached to pulleys, those are extension springs.

Why Professional Installation Matters
Springs are under extreme tension. Torsion springs can exert 200 pounds or more of rotational force. Extension springs pull with similar force. Mishandling them, using the wrong gauge, or installing them incorrectly can cause serious injury or property damage.
A professional installer measures your door, calculates the correct spring size, and installs the new spring with proper tools and safety protocols. We also balance the door so your opener doesn't work harder than it needs to. That's why our spring replacement cost guide emphasizes that cheap DIY attempts often cost more in the long run.
If you're also having opener issues, know that the wrong spring type can damage a new opener. Learn more about choosing the right opener for your door, because springs and openers work together.

Frequently Asked Questions
Q: Can I replace just one spring if one is broken? A: Both springs are the same age and wear. If one snapped, the other will follow soon. We recommend replacing both torsion springs or both extension springs at the same time to keep your door balanced and safe.
Q: How much does spring replacement cost in New Britain? A: Torsion spring replacement typically runs $200 to $400 per spring, including labor and parts. Extension springs are usually $150 to $300 per spring. See our full pricing breakdown for more detail.
Q: Can I lubricate my springs to make them last longer? A: Yes. Light oil or garage door lubricant spray on torsion springs (not the coils, but the shaft and bearings) reduces friction and extends life. Extension springs benefit from occasional lubrication too, but avoid over-application, which attracts dust.
Q: What's that loud bang noise when my garage door opens? A: Usually a sign a spring is failing or has already snapped. Stop using the door and call us immediately. A loud pop or crack means the door's weight isn't balanced.
Q: How do I know if my spring needs replacement soon? A: If your door feels heavy, the opener struggles, or you hear creaking or grinding, springs may be wearing out. We offer free inspections to assess remaining life on both types of springs.
