Torsion vs. Extension Springs in Clermont: Which Does Your Garage Door Need?
2026-09-13 7 min read
If you've ever looked under your garage door and wondered what those metal coils actually do, you're not alone. After 15 years on the trucks around Clermont, I've had countless homeowners ask me the same question: what's the difference between torsion and extension springs? The short answer is that torsion springs sit above your door and twist to lift it, while extension springs run along the sides and stretch to do the same job. One is safer, one is cheaper, and knowing which type you have matters when something breaks.
What Are Garage Door Springs, and Why They Matter
Your garage door weighs between 300 and 500 pounds. Without springs, you'd need serious arm strength to open it manually, and your garage door opener would burn out in months. Springs counterbalance that weight, making the door feel light as you lift it. They're not just convenience features. They're safety systems that keep your door from crashing down on your car, your kids, or your fingers.
Springs typically last 7 to 9 years with normal use (opening and closing your door about 4 times daily). When they wear out, you'll notice your door moving slowly, sagging on one side, or refusing to open at all. That's when most homeowners call us for a same-day estimate.
Torsion Springs Explained
Torsion springs mount horizontally on a shaft above your garage door opening. When you open the door, they twist (or torque) like a wound-up clock spring, storing energy and lifting the door. Most residential garage doors in Clermont use torsion springs because they're durable, predictable, and safe.
Here's the real advantage: torsion springs have a metal rod running through them, so if one snaps, the rod keeps it in place. No flying metal. Extension springs, by contrast, can whip across the garage like a bullet if they break. I've seen extension springs take out windows and dent cars. That's why insurance companies and building codes favor torsion.
Torsion springs cost a bit more upfront (usually $200 to $400 for a pair, installed), but they last longer and fail more predictably. If you're shopping for a garage door spring replacement in Clermont, ask your technician whether your door uses one spring or two. Some heavier doors need dual springs for balance.

Extension Springs: The Budget Option
Extension springs run along the top of your garage door tracks, one on each side. When the door opens, they stretch like rubber bands, pulling upward on the tracks to assist the opener. They're cheaper than torsion springs and take up less space, which makes them popular on older doors and single-car garages.
The downside is safety. When an extension spring snaps, there's nothing stopping it from swinging across your garage at high speed. Most extension springs have safety cables running through them to catch a broken spring, but cables can fray or snap too. Over the years, I've replaced more extension springs than I can count, and I always recommend upgrading to torsion if the budget allows.
Extension springs typically cost $150 to $250 per pair installed, making them the cheaper upfront choice. But if you're planning to stay in your Clermont home for more than a few years, the safety and longevity of torsion springs usually win out.
How to Tell Which Type You Have
Walk into your garage and look above the door opening. If you see a horizontal metal shaft with coils wrapped around it, you have torsion springs. If you see two springs running along the top of the tracks on either side of the door, those are extension springs. It's that simple.

When to Repair vs. Replace
If one spring snaps, you have two options: replace just that spring, or replace both. I always recommend replacing both at the same time, even if only one is broken. Springs age together. The one that didn't snap is already weakened and could fail within weeks or months. Replacing both costs a bit more upfront but saves you from a second repair call and keeps your door balanced.
If your springs are more than 8 years old and showing signs of wear, replacement is the smarter move than repair. Read more about repair vs. replacement decisions here to help you decide.
The Cost of Ignoring Broken Springs
A snapped spring won't just strand your car in the garage. It puts extra strain on your opener, which can burn out a $300 to $500 motor. A stuck door also means no access for deliveries, emergency vehicles, or your own evacuation in a fire. I've seen homeowners put off spring repairs for weeks, only to face a $1,000+ bill when the opener fails too.
When springs snap, same-day repair isn't a luxury. It's your best financial move. Garage Door Clermont handles emergency calls around the clock because we know how disruptive a broken door is.
Frequently Asked Questions
How long do garage door springs last? Most residential springs last 7 to 9 years with normal use (about 1,500 cycles per year). Lifespan depends on door weight, climate, and maintenance. Springs in humid climates like Central Florida may wear faster due to rust.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if mishandled. A trained technician has the tools, knowledge, and insurance to do it safely. Always hire a professional.
What's the difference in cost between torsion and extension springs? Torsion springs cost $200 to $400 installed. Extension springs run $150 to $250. Labor is similar, but torsion springs are heavier and more complex to install, so they tend to cost more overall.
Do I need to replace springs if my garage door opener still works? Yes. A weak or broken spring forces your opener to work harder, burning out the motor faster. Replacing springs prevents opener failure and keeps your door balanced and safe.
Should I replace one spring or both? Always replace both. Springs age as a pair. The unbroken one is already weakened and will fail soon, leaving you with another emergency repair. Replacing both saves money and hassle long term.
