Garage Door Spring Types in Bozrah: Torsion vs. Extension Explained
2026-08-15 7 min read
In our years serving Bozrah, we've seen this problem again and again: homeowners don't know what type of garage door springs they have until one snaps. Understanding whether your door uses torsion or extension springs isn't just technical trivia. It affects repair cost, safety, and how long you'll go between replacements. Let's break it down so you can make informed decisions about your garage.
How Torsion Springs Work
Torsion springs sit horizontally above your garage door opening. They twist and wind as your door moves up and down, converting rotational energy into the force needed to lift a heavy door. Think of them like a clock spring that's been scaled up dramatically. One good torsion spring can handle the full weight of your door, which is why most modern residential doors rely on this design.
These springs last roughly 7 to 9 years with normal use, and they're engineered to cycle a specific number of times. Once that cycle count is exhausted, the metal fatigues and fails. The failure tends to be sudden and loud. You'll hear a sharp crack or pop when they go.
How Extension Springs Work
Extension springs run along the sides of your door frame. Instead of twisting, they stretch and contract as the door moves. When your door opens, they extend. When it closes, they contract. Two springs share the load equally, so each one handles roughly half the weight.
Extension springs typically last 5 to 7 years, which is shorter than torsion springs. They're also more prone to wear because they rely on friction and moving pulleys. If you have an older home in Bozrah or a particularly heavy door, extension springs might be what's installed.
Which Type Do You Have?
Look above your garage door. If you see a single horizontal rod with a coil wrapping around the middle, you have a torsion spring setup. If you see two springs running vertically along each side, those are extension springs. Don't touch either one. They're under extreme tension and can cause serious injury if they snap while you're near them.

Cost and Replacement Differences
Torsion spring replacement typically costs more than extension spring repair because installation requires specialized tools and expertise. Extension springs are cheaper to replace individually, but you often need both changed at the same time for safety and balance. We've covered this in detail before: check our guide on why DIY spring replacement costs more in the long run.

The price difference between the two types also reflects their lifespan. If you're replacing springs, torsion is often the better long-term investment even if it costs more upfront. You'll spend less on repairs over the next decade.
Why This Matters for Your Safety
A snapped spring doesn't just leave you unable to open your garage. It puts strain on your garage door opener, which then tries to lift the door's full weight without spring assistance. Openers aren't designed for that. You risk damaging the motor, the gears, or the door itself.
More importantly, springs under tension are a genuine safety hazard. If you have a snapped spring, treat it as an emergency. Don't try to open the door manually and don't attempt a DIY fix. Read our post on professional spring replacement to understand why this matters.
Prevention Through Maintenance
The best way to avoid surprise spring failure is preventive maintenance. An annual inspection catches wear early and extends the life of your springs. Lubrication reduces friction, and professional adjustment keeps your door balanced and safe. Most homeowners don't think about their garage until something breaks, but a simple tune-up prevents costly repairs down the road.
If your springs are approaching their expected lifespan, schedule an estimate now. Replacing both springs while they're still functional costs less than emergency repair when one fails at the worst possible time.

Frequently Asked Questions
How do I know if my torsion spring is broken? You'll typically hear a loud snap or bang when the spring fails. Afterward, your garage door will be extremely heavy to lift manually, or the opener won't budge it at all. Never force it. Call for professional help immediately.
Can I replace just one extension spring? Technically yes, but we recommend replacing both at the same time. Springs wear at roughly the same rate, and replacing only one throws your door out of balance, causing uneven wear on the remaining spring and your opener.
How much does a spring replacement cost? Torsion spring replacement typically ranges from $200 to $400, while extension springs run $150 to $300. Exact pricing depends on your door's weight and your location. Request an estimate for precise numbers.
How long do garage door springs last? Torsion springs last 7 to 9 years under normal use. Extension springs typically last 5 to 7 years. Lifespan depends on frequency of use, climate, and maintenance habits.
Should I replace springs before they break? If your springs are within one year of their typical lifespan, we recommend proactive replacement. It's far less expensive and inconvenient than handling an emergency failure.
