Garage Door Springs in East Sandwich: Torsion vs. Extension Explained

2026-08-21 7 min read

Garage door springs come in two main types: torsion and extension. Torsion springs sit above your door and twist to lift the weight. Extension springs run along the sides and stretch to do the job. Most modern homes in East Sandwich use torsion springs because they're safer and last longer. Both fail eventually, and when they do, your door won't open or close without serious risk.

I've pulled too many hands out of garage door frames to count. Most injuries happen when homeowners try to fix springs themselves after one snaps. Don't be that person.

Understanding Torsion Springs

Torsion springs are the gold standard. They're mounted horizontally above the center of your door on a metal shaft. When the door closes, the springs wind up like a clock. When you press the opener button, that stored energy unwinds and lifts the 300+ pound door almost effortlessly.

Here's what matters: torsion springs last 7 to 9 years under normal use. That assumes regular maintenance and no extreme weather swings. Cape Cod's freeze-thaw cycles can accelerate wear, especially if salt air gets to the metal. A properly functioning torsion spring means your garage door opener only has to lift about 10 pounds of actual load, not the full weight.

When a torsion spring snaps, you'll hear a loud bang. The door may drop suddenly or jam halfway. Do not attempt to open it manually. Do not call your general handyman. This is a job for someone trained in spring systems.

Extension Springs and Their Risks

Extension springs run parallel to the tracks on both sides of your door opening. They stretch and contract as the door moves. They're cheaper upfront but weaker and wear out faster than torsion springs.

Extension springs have pulleys, cables, and safety cables. That's more parts. More parts mean more ways things can fail. If an extension spring breaks, the cable can snap loose and whip across your garage like a bullwhip. I've seen them take chunks out of drywall. Imagine what they'd do to a face or hand.

Safety cables run through the center of extension springs specifically to catch them if they snap. Older systems might not have these. If your home was built before 1990, yours might not either.

Why Springs Fail and What You'll See

Springs fail because they're under constant tension. Metal fatigues. Rust accelerates failure, especially near the coast. Poor maintenance, lack of lubrication, and extreme temperature swings all shorten the lifespan.

Watch for these warning signs: your door feels heavier than normal, the opener strains to lift it, or you hear creaking sounds from above the door. These hints often mean springs are near the end. Learn about preventive maintenance tune-ups in East Sandwich to catch problems before springs fail.

A snapped spring is an emergency. Your door is stuck. You can't get your car out. Maybe you can't get inside the house. Don't wait for a convenient time to call. Find out what emergency service actually costs and why it's worth every penny.

The Cost of Spring Replacement

Torsion spring replacement costs between $200 and $400 per spring for materials and labor combined. Extension springs run $150 to $300 per pair. Emergency service (nights, weekends, holidays) adds 50 to 75 percent.

Here's the reality: most homeowners find DIY spring repair tempting because the parts seem affordable. But the risk isn't worth saving $100 or $200. Springs store enormous amounts of energy. A mistake means a garage door falling on your head or fingers getting caught in cables. Hospital visits cost far more than professional replacement.

Frequently Asked Questions

How long do garage door springs typically last? Torsion springs last 7 to 9 years with regular maintenance. Extension springs often fail sooner, around 5 to 7 years. Heavy use, salt air, and poor lubrication shorten lifespan significantly. Most homeowners replace both springs together.

Can I replace just one spring if only one snaps? No. If one spring fails, the other is likely near failure too. Replacing both at the same time prevents your door from becoming unbalanced and wearing unevenly. Costs less long-term than replacing one, then the other six months later.

What's the difference between a snapped spring and worn springs? A snapped spring breaks suddenly and completely. Worn springs lose tension gradually, making your door feel heavier and your opener work harder. Worn springs give you time to schedule replacement. Snapped springs require emergency service.

Is it safe to use my garage door if I suspect a spring is broken? No. Using a garage door with a broken or failing spring puts enormous strain on the opener and creates a safety hazard. The door could fall unexpectedly. Call for service immediately.

Why does spring replacement cost more than the parts alone? Professional replacement requires specialized tools, a lift or ladder work at height, precise tension adjustment, and liability insurance. Improper tension causes premature wear and safety issues. The labor protects your investment and your family.
