Garage Door Springs in East Dennis: Torsion vs. Extension Explained
2026-08-10 7 min read
Garage door springs come in two main types: torsion and extension. Torsion springs sit above the door and twist to lift weight; extension springs run along the sides and stretch. Most modern homes use torsion because they're safer and last longer. A snapped spring means your door won't open, and you'll need professional help same-day.
Why Springs Fail (And It's Not Your Fault)
Your garage door springs work overtime. Every time the door opens or closes, they bear the full weight of the door (typically 300 to 500 pounds). Springs last roughly 7 to 9 years under normal use. But salt air near the coast, temperature swings in East Dennis winters, and lack of lubrication accelerate wear.
A snapped spring isn't a slow death. It happens fast. You'll hear a loud bang, and the door becomes impossible to lift manually. This is when homeowners call us in a panic. The good news: it's fixable, and faster than you'd expect.
Torsion Springs: The Industry Standard
Torsion springs are wound coils that store energy as they twist. When you open your garage door, they unwind and counterbalance the door's weight. This design is safer because the spring sits above the door on a metal shaft, contained and protected from accidental contact.
The trade-off: torsion springs cost slightly more to replace than extension springs. But they last longer and are worth every penny. If your door uses torsion springs, replacement typically runs between $200 and $400 per spring, plus labor. You usually need both springs replaced at once because when one fails, the other is close behind.
We recommend learning about garage door spring maintenance in East Dennis to extend the life of your springs. Regular lubrication and inspection catch wear before it becomes an emergency.
Extension Springs: Older Doors and Budget Options
Extension springs stretch along the sides of the door frame. They're common in older garage doors and carry a lower upfront cost ($100 to $200 per spring). However, they require safety cables running through them. If an extension spring snaps, the cable catches the spring and prevents it from whipping dangerously across the garage.
Extension springs wear faster because they stretch thousands of times annually. If your door uses them, inspect them every year. Many homeowners don't realize they have extension springs until one fails.

What Actually Causes Spring Failure
Springs fail for a few clear reasons. Rust builds up in coastal areas like Dennis. Lack of lubrication forces the metal to work harder. Temperature swings in New England cause metal expansion and contraction, creating micro-fractures. And sometimes, a spring simply reaches the end of its service life.
If your door has been stuck or laboring to open, that's a sign springs are weakening. Don't ignore it. A failing spring puts strain on your garage door opener and can lead to much costlier repairs down the road. We've seen homeowners try to work around a bad spring only to replace the entire opener later.

Prevention: The Real Cost Savings
The best way to avoid a snapped spring is maintenance. Lubricate your springs twice a year (spring and fall). Keep the door balanced by testing it without the opener. And have a professional inspect springs as part of your annual garage door tune-up.
A $50 maintenance call now beats a $400 emergency replacement later. That's not just good business. It's the right way to treat your home.

Frequently Asked Questions
How do I know if my garage door spring is broken? You'll hear a loud bang when the spring snaps. After that, the door won't open or feels extremely heavy to lift manually. You may also see the door hanging unevenly on one side.
Can I replace a garage door spring myself? We don't recommend it. Springs are under extreme tension and can cause serious injury if mishandled. Always hire a licensed technician. It's safer and faster than DIY attempts.
How much does a garage door spring replacement cost? Torsion springs run $300 to $500 installed; extension springs run $200 to $350. Emergency or weekend service adds an extra fee. Call (508) 456-5246 for an exact quote.
Why do both springs need replacing if only one broke? Springs age together. When one fails, the other is usually near the end of its life too. Replacing both now prevents a second failure within weeks.
How long do garage door springs last? Most springs last 7 to 9 years with regular use. Coastal salt air and lack of maintenance shorten that lifespan. Proper lubrication and inspection extend it.
