Garage Door Springs in Burlington, MA: Torsion vs. Extension Explained
2026-06-05 8 min read A2Z Garage Doors
Your garage door relies on springs to lift roughly 300 to 400 pounds with ease. Most homeowners don't think about garage door springs in Burlington until one snaps, leaving the door stuck or dangerously heavy. Understanding the two main types, torsion and extension, helps you recognize problems early and avoid costly emergencies.
The Two Spring Types: Torsion vs. Extension
Torsion springs sit horizontally above your garage door opening. They work like a wound coil that releases energy to counterbalance the door's weight. When you open the door, tension slowly unwinds; when you close it, the spring rewinds. This design is smooth, precise, and typically lasts 7 to 9 years under normal use. See our guide on garage door openers in burlington, vt: chain, belt, screw drive, and smart openers explained.
Extension springs run vertically along each side of your door track. They stretch and contract as the door moves up and down. You'll often see them paired with pulleys and cables. Extension springs wear out faster than torsion springs because they endure more repetitive stress.
Most homes built in the last 20 years use torsion springs. If your garage door won't open or feels unusually heavy, the culprit is often a snapped spring on one or both sides. Read about winter garage door problems in burlington: what.
Why Springs Break: The Real Story
I've responded to hundreds of service calls in Burlington and the surrounding areas. The worst cases involve a snapped spring that homeowners try to force. The door crashes down, pinches fingers, or damages the opener motor.
Springs fail for predictable reasons. First, age. After 7 to 9 years of daily opening and closing, metal fatigues and loses elasticity. Second, rust. Massachusetts winters and moisture accelerate corrosion, especially on extension springs. Third, lack of maintenance. A door that hasn't been lubricated or serviced strains the springs unnecessarily.
One scenario I've seen repeatedly: a homeowner ignores squeaking or grinding noises (early warning signs), then one morning the door won't budge. At that point, you've got a safety hazard and a more expensive repair ahead. That's why our garage door maintenance guide covers seasonal checks that catch problems before they become emergencies.
When You Need Professional Help
Never attempt to replace or adjust garage door springs yourself. The tension stored in a torsion spring can cause serious injury or death. Even a partially unwound spring can snap and strike your face or hands without warning.
If you hear a loud bang or notice your door is off-balance, stop using it immediately. Call a licensed technician. A professional diagnosis takes minutes; guessing costs money and creates risk.

Cost and Repair vs. Replacement
A snapped spring doesn't always mean total replacement. If the spring is new or relatively young, we may repair the broken section. However, if both springs are approaching their lifespan, replacing both at once is smarter. One spring will fail soon after the other, and you'll pay for another service call.
Spring replacement typically costs between $150 and $400 per spring, depending on type and quality. A full garage door springs repair cost estimate will be clearer once a technician inspects your door. Many people don't realize that extension springs often need cable replacement too, which adds to the final cost.

Prevention: The Cheapest Repair
Lubricate your springs every three months with a silicone-based garage door lubricant. This reduces friction and slows rust formation. Keep the garage reasonably dry. In winter, brush snow and ice away from the bottom seal so the door closes smoothly without strain.
Schedule annual maintenance with a professional. We'll inspect spring tension, check cable alignment, and spot early signs of wear. It costs far less than emergency repairs and keeps your family safer. Explore our full garage door services to learn what a maintenance plan includes.

Frequently Asked Questions
Can a broken garage door spring be repaired, or does it need replacement? Broken springs almost always require full replacement, not repair. Springs are under extreme tension and cannot be safely welded or patched. A professional will replace the damaged spring and often recommend replacing its pair to avoid a second failure soon after.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with regular use. Extension springs often fail sooner, around 5 to 7 years. Lifespan depends on frequency of use, lubrication, and climate. Harsh winters and rust accelerate wear.
Is it safe to open my garage door if one spring is broken? No. A broken spring throws the door off-balance and creates excessive strain on the opener and cables. The door may fall suddenly or cause motor damage. Stop using the door and call a technician immediately.
What's the difference between torsion and extension springs in cost? Torsion springs are generally more expensive to replace (typically $200 to $400 per spring) but last longer. Extension springs cost $150 to $250 per spring but need replacement more frequently. Over time, torsion systems often provide better value.
Why should I replace both springs if only one broke? Both springs wear at similar rates since they share the door's weight equally. If one has failed, the other is near the end of its life. Replacing both prevents a second failure within weeks and saves money on service calls.
