Garage Door Spring Types in Franklinton: Torsion vs. Extension (Which Do You Have?)

2026-09-26 4 min read

Serving Franklinton, we see this problem again and again: homeowners don't know which type of spring their garage door uses, so they can't explain the issue when they call for help. Here's the plain truth: most doors run either torsion or extension springs, they work completely differently, and knowing which one you have saves time and money when something breaks.

The Two Main Types: Torsion vs. Extension

Torsion springs mount horizontally above your garage door opening, along the header beam. They twist (torque) to lift and lower the door. Think of them like a tightly wound coil that stores energy as it rotates. When you open the door, that coil unwinds, doing most of the heavy lifting.

Extension springs run vertically on both sides of your door, above the horizontal tracks. They stretch and contract like a rubber band. As the door goes down, they extend. As it goes up, they contract, pulling the door upward. They're usually paired (one on each side) and connected by a cable system.

The difference matters because they behave differently when they fail, cost different amounts to replace, and require different safety precautions during repair.

Why Torsion Springs Are More Common in Franklinton Homes

Most residential garage doors in Franklinton and the surrounding area use torsion springs. They're more durable, last longer (typically 7 to 10 years with regular use), and handle heavier doors better. They also fail more predictably, which is actually a safety bonus.

Torsion springs typically last 10,000 to 15,000 cycles (one cycle equals one open-close). Extension springs usually max out at 7,000 to 10,000 cycles. A typical household opens and closes their door twice a day, so torsion springs outlast extension ones by years.

If you're unsure which type you have, look above your door opening. A horizontal wound spring = torsion. Vertical springs running up the sides = extension.

What Happens When a Torsion Spring Snaps

A snapped torsion spring is loud. You'll hear a sharp bang or crack, sometimes loud enough to startle you. The door becomes extremely heavy suddenly because you've lost that twisting assist. The door won't open smoothly. It might jam or feel stuck.

This is dangerous. A snapped torsion spring means your opener is now trying to lift a door weighing 300 to 500 pounds without help. The opener can burn out in seconds. If you hear that snap, don't keep trying to open the door.

What Happens When an Extension Spring Breaks

Extension springs fail differently. You'll notice the door opening unevenly, tilting to one side. That's because one spring is still working while the other isn't. The door might still move, but it's pulling lopsided, which strains your opener and tracks.

Extension springs are also under constant tension, so when one snaps, the cable it's attached to can whip around. That's a pinch and cut hazard. Never reach near a broken extension spring.

Cost and Repair Differences

Torsion spring replacement typically costs more than extension spring replacement, but torsion springs last much longer, so your cost per year is actually lower. Extension springs are cheaper upfront but you'll replace them more often.

Both types require professional installation. The tension in these springs is extreme. A spring under load can cause serious injury if it slips during removal or installation. This isn't a DIY job, even if you're handy.

When to Call a Pro

If your door opens slowly, jerks, or feels heavier than normal, your springs might be wearing out. Don't wait for a complete failure. A pre-failure inspection can catch a weakening spring before it snaps and potentially damages your opener or door panels.

Frequently Asked Questions

How do I know which spring type I have? Look above your garage door opening. Torsion springs run horizontally across the header beam above the door. Extension springs run vertically on the sides, above the tracks. If you're unsure, a technician can identify it in seconds.

Can I replace just one spring if both are the same age? Not recommended. Springs wear together. If one snapped, the other is close behind. Replacing both at once prevents a second failure weeks later and saves you the service call cost.

Why is spring replacement so expensive? The springs themselves cost $15 to $30 each, but the labor is high because of the danger and precision required. The technician must safely remove tension, unwind the old spring, wind the new one to exact specifications, and test everything. One mistake causes injury.

How often should I have my springs inspected? At least once a year as part of routine maintenance. Springs lose tension gradually, and early warning signs are subtle. We offer garage door maintenance tune-ups in Franklinton that include spring inspection.

What's the lifespan of a garage door spring? Torsion springs last 7 to 10 years under normal use (two cycles per day). Extension springs last 5 to 8 years. Lifespan depends on usage, climate, and maintenance. Harsh winters in the Franklinton area can shorten the timeline.
