Garage Door Spring Types in North Falmouth: Torsion vs. Extension Explained
2026-07-19 7 min read
In our years serving North Falmouth, we've seen this problem again and again: homeowners don't know which type of garage door spring they have, so they panic when one fails or makes noise. The truth is simple. Your door uses either a torsion spring or an extension spring, and knowing which one matters for safety, cost, and repair speed. We'll break down both types, explain how they work, and help you understand what yours needs.
What Are Garage Door Springs?
Garage door springs are the hardworking metals that counterbalance your door's weight. Without them, you'd need superhuman strength to lift a door that weighs 300 to 400 pounds. They store and release energy, making the opener's job easy. Springs last roughly 7 to 9 years under normal use, though coastal salt air in North Falmouth can shorten that lifespan. When a spring snaps or wears out, your door won't open or close safely, and you'll need professional help fast.
Torsion Springs: The Most Common Choice
Torsion springs sit horizontally above your garage door, mounted on a metal shaft. They twist and untwist to lift and lower the door. Most residential doors in North Falmouth use torsion springs because they're durable, precise, and safer than their counterparts.
Here's how they work: as your door closes, the spring tightens (torques). As it opens, the spring unwinds, releasing stored energy. This smooth action protects your door's tracks and panels from stress. A snapped torsion spring creates an immediate problem. Your door becomes extremely heavy, and the opener can't lift it. Worse, a broken spring can cause the door to slam down unexpectedly, which is why we always recommend professional repair.
Torsion springs cost more upfront than extension springs, typically $150 to $300 for the spring itself, plus labor. But they last longer and cause fewer accidents, so the investment pays off.

Extension Springs: The Budget Alternative
Extension springs run along both sides of your door, inside the tracks. They stretch and contract to balance the door's weight. Older homes and lighter doors sometimes use extension springs because they're cheaper and take up less space.
The downside? They're less stable and wear faster than torsion springs. When an extension spring snaps, the door can jerk to one side, damaging the track or panel. Extension springs also require safety cables running through them. If the spring breaks, the cable keeps the spring from whipping across the garage. Still, extension springs are riskier, and we don't recommend them for new installations.

How to Identify Your Spring Type
Stand in your garage and look above the door. If you see a long metal shaft running horizontally with a coiled spring wrapped around it, you have a torsion spring. If you see two springs running vertically along the sides of the door tracks, those are extension springs. Don't touch them. Springs are under extreme tension and can cause serious injury.

Spring Replacement: Same-Day Service Available
Both spring types need professional replacement. Trying to do it yourself can result in injury or damage to your opener and door. At Garage Door North Falmouth, we stock both torsion and extension springs and can install them the same day you call, depending on timing.
The total cost depends on the spring type, door weight, and whether your door has one or two springs. We'll explain all this when we give you an estimate. If you're also concerned about safety, read our garage door spring warning signs guide to learn what to watch for before a spring fails.
Maintenance Tips to Extend Spring Life
Springs wear out naturally, but you can slow the process. Lubricate your springs twice a year with a garage door lubricant (not WD-40). Keep the tracks clean and aligned. Have a professional safety inspection done every two years, especially if you live near the coast where salt corrosion accelerates wear.
Your garage door springs work hard every single day. Whether torsion or extension, they deserve attention. When you notice squeaking, slow movement, or uneven opening, don't wait. A small problem becomes expensive fast.

Frequently Asked Questions
How long do garage door springs last? Most springs last 7 to 9 years with normal use, roughly 10,000 open/close cycles. Coastal environments like North Falmouth experience faster corrosion, potentially shortening lifespan by 1 to 2 years.
Can I replace one spring if the other is still working? We recommend replacing both springs at the same time, even if only one snapped. Springs wear together, and replacing one leaves an imbalanced load on the newer one, causing premature failure.
What's the difference in cost between torsion and extension spring replacement? Torsion springs typically cost $150 to $300 plus labor. Extension springs run $75 to $150 plus labor. Total service calls average $200 to $400 depending on the type and your location in North Falmouth.
Is it safe to use my garage door if a spring is broken? No. A broken spring means your door is extremely heavy and unsafe to operate. The opener can't lift it properly, and the door may fall suddenly. Stop using it and call for professional help immediately.
Why do springs fail in North Falmouth faster than inland areas? Salt air accelerates rust and corrosion on metal springs. The constant moisture and salt exposure weaken the steel, causing premature cracking and failure. Regular lubrication and maintenance help but don't fully prevent it.
