Extension vs. Torsion Garage Door Springs in Jonesville: Which Does Your Door Need?
2026-09-15 7 min read
In our years serving Jonesville, we've seen this problem again and again: homeowners don't know which type of garage door springs they have until one breaks. Understanding the difference between extension and torsion springs isn't just academic. It affects cost, safety, and how quickly we can get you back in your garage.
What Are Garage Door Springs, and Why the Types Matter
Your garage door weighs between 300 and 500 pounds. That weight doesn't lift itself. Two springs handle nearly all of that load, working in opposition to your opener to make the door move smoothly up and down. When one fails, the other bears double stress. That's why knowing your spring type matters before something snaps.
Both extension and torsion springs store and release energy, but they do it differently. The type you have determines repair cost, replacement timeline, and even which technician can safely handle the job. Misidentifying your spring type can lead to ordering the wrong part or, worse, attempting a DIY fix that puts you in real danger.
How Torsion Springs Work
Torsion springs sit horizontally above your garage door opening, on a shaft that runs the width of your door. They twist and wind as your door opens and closes, storing energy in that coiled metal. When you press the opener button, the torsion spring unwinds, helping lift the heavy door with minimal effort from your motor.
Torsion springs are the industry standard in modern garages because they're durable, smooth, and precise. They typically last 7 to 9 years with regular use. One properly sized torsion spring can handle your entire door weight, which is why most newer homes have just one (though some have two for extra duty cycles or heavier doors).
The trade-off? Torsion springs are under intense tension. If you see a snapped torsion spring, don't touch it. The sharp metal ends and stored energy make it a serious safety hazard.
How Extension Springs Work
Extension springs run vertically along both sides of your door opening, one on each side. They stretch and compress as the door moves, pulling your door up and pushing it down. You'll see them attached to cables that guide and stabilize the door's movement.
Extension springs are common in older homes and lighter-duty garage doors. They're less expensive upfront than torsion systems, but they typically need replacement more often. When one snapped spring fails, the other side bears all the load, creating uneven stress that can damage your door tracks and opener.
If you have extension springs and one breaks, you'll likely need both replaced at the same time. We always recommend this approach to avoid a second failure within months.

How to Identify Which Type You Have
Stand in your garage and look above the door. If you see a long, horizontal metal shaft with coils wrapped tightly around it, you have torsion springs. They run the full width of your opening and look like a twisted metal rod.
If you see two springs running vertically down the sides of your door frame, connected to cables, you have extension springs. Each one stretches and contracts independently as the door moves.

Cost and Replacement Considerations
Torsion spring replacement typically costs more than extension spring work because the springs themselves are pricier and installation requires precise measurements and specialized tools. Most torsion jobs near Jonesville run between $250 and $400 per spring, plus labor.
Extension spring replacement is usually less expensive upfront, often $100 to $200 per spring. However, if you wait too long after the first spring fails, you risk damaging your door and tracks, which adds to the total cost.

Why Professional Installation Matters
A snapped spring isn't a job for the average homeowner. Springs carry enough tension to cause serious injury if handled incorrectly. We've treated customers who tried DIY spring replacement and ended up in the emergency room.
Our technicians measure your door weight, confirm your spring type, and install the correct replacement with proper tension. We also inspect your cables, brackets, and hardware while we're there. That's how you avoid a second failure six months later.
If you're experiencing spring problems right now, don't wait. A broken spring puts stress on your opener and can cause further damage. Schedule your free quote today or call (336) 742-1084.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with regular use. Extension springs often need replacement sooner, sometimes in 5 to 7 years. Lifespan depends on climate, usage frequency, and maintenance.
Can I replace just one spring? For torsion springs, we recommend replacing both if one fails, even though only one broke. Both springs age together, and the surviving spring is now under extra stress. Extension springs should always be replaced in pairs.
What's the difference in price between torsion and extension? Torsion springs cost more upfront, typically $250 to $400 per spring installed. Extension springs run $100 to $200 each. Torsion systems are more durable and smooth, making the higher cost worthwhile for most homeowners.
Is it safe to use my garage door if one spring is broken? No. A broken spring puts dangerous strain on your opener and door tracks. You risk further damage and possible injury. Call a professional immediately for safe removal and replacement.
