Garage Door Spring Types in Westborough: Torsion vs. Extension Explained

2026-09-21 7 min read

Serving Westborough, we see this problem again and again: homeowners don't know which type of spring their garage door uses until one snaps. The two main types are torsion springs and extension springs. Torsion springs sit above the door and twist to lower and raise it. Extension springs run along the sides and stretch to do the same work. Which one you have matters for repair cost, replacement safety, and how long the spring will last.

Torsion Springs: How They Work and Why They Break

Torsion springs are the heavy lifters of garage door systems. They're mounted horizontally above the door opening on a steel shaft. When you open the door, the spring winds up tighter, storing mechanical energy. When you close it, that energy unwinds to lower the door smoothly.

Most modern homes in Westborough use torsion springs because they're more durable and balanced than extension springs. A typical torsion spring lasts 7 to 9 years with normal use (roughly 10,000 cycles). That means if you open and close your door four times daily, you'll get solid longevity.

But torsion springs fail when the metal fatigues. Every cycle puts stress on the coils. Eventually, the metal crystallizes and snaps. When it does, the door becomes very heavy very fast. You'll hear a loud bang from the garage. The door won't open without the garage door opener working twice as hard, and it may not close smoothly at all.

Why Professional Help Is Critical

Never attempt to replace a torsion spring yourself. These springs are under extreme tension. A slip or mistake can cause serious injury. We always recommend calling a licensed professional near you who understands the physics and has the right tools.

Extension Springs: The Lighter-Duty Alternative

Extension springs hang along each side of the garage door opening, above the horizontal tracks. Instead of twisting, they stretch and contract. As the door rises, the springs extend. As it falls, they compress.

Extension springs typically last slightly longer than torsion springs, around 8 to 10 years. However, they're less smooth in operation and can create more wear on other components. Older homes and lighter residential doors often use extension springs.

When an extension spring snaps, the door may jerk to one side during operation. You might hear a sharp twang. Unlike a torsion spring failure, the door may still operate, but unevenly and with strain on the opener.

Cost and Replacement Timeline

Spring replacement cost varies based on the type, your door's weight, and local labor rates. Torsion springs typically run higher than extension springs because installation is more technical. Most homeowners in the greater Boston area can expect estimates ranging from moderate to higher, depending on whether you need one spring or a pair.

The good news: if you catch a snapped spring early and schedule service right away, we can often get you a same-day estimate and same-day or next-day replacement. Waiting weeks to fix a broken spring means your garage door opener works overtime, potentially causing secondary damage.

How to Know Which Type You Have

Stand inside your garage with the door closed. Look above the door. If you see a metal shaft running horizontally with a coiled spring wound around it, you have a torsion spring. If you see two springs running vertically along the tracks (one on each side), those are extension springs.

If you're unsure or need a professional assessment, schedule a free quote and we'll identify your system and provide an accurate estimate on the spot.

When to Call for Help

Don't wait for a spring to snap completely. Warning signs include uneven door movement, creaking sounds during operation, or visible rust on the springs. These indicate the spring is aging and may fail soon.

Also, if your door has been working fine but suddenly feels heavier than usual, a spring might be partially compromised. A snapped garage door spring in Westborough requires urgent attention, especially if you need to access your garage regularly.

Frequently Asked Questions

How long do garage door springs last? Torsion springs typically last 7 to 9 years, while extension springs last 8 to 10 years. Lifespan depends on usage frequency, climate, and maintenance. Springs rated for 10,000 cycles may last longer or shorter depending on whether you open and close your door multiple times daily.

Can I replace just one spring if only one is broken? No. Springs work as a pair to balance the door. If one snaps, the other is likely near failure too. Replacing both ensures even operation and prevents the second spring from breaking weeks later, causing a second service call.

What's the difference between torsion and extension spring cost? Torsion springs usually cost more to replace because installation is more complex and requires specialized tools and expertise. Extension springs are simpler to install but provide less smooth operation and wear other components faster over time.

Is a broken garage door spring an emergency? Yes, especially if you need regular garage access. A snapped spring means the door won't operate properly and puts extra strain on the opener. We offer same-day emergency service in Westborough. Call 1-508-682-5955 right away.

Should I try to fix a spring myself? Absolutely not. Garage door springs are under extreme tension and can cause serious injury if mishandled. Always hire a licensed professional. Safety is not the place to cut costs.
