Garage Door Spring Types in Weldon: Torsion vs. Extension Explained
2026-09-08 7 min read
There are two types of garage door springs that power your door: torsion springs and extension springs. Torsion springs sit above your door on a horizontal rod and twist to lift the weight. Extension springs run along the sides and stretch to do the work. Knowing which one you have matters because replacing the wrong type can damage your opener or, worse, cause the door to crash down without warning.
I've responded to too many emergency calls in Weldon and the surrounding areas where a homeowner tried a DIY fix or hired an unlicensed handyman who didn't understand this basic distinction. That's why I'm walking you through both types today, so you can recognize what's in your garage and make smart repair decisions.
Torsion Springs: The Safer, Longer-Lasting Option
Torsion springs are the gold standard in residential garage doors. They're mounted horizontally above the door opening on a metal rod, and they work by twisting (torquing) to counterbalance the door's weight as it opens and closes.
Here's what makes torsion springs superior:
- They last 7 to 9 years with regular use, compared to 5 to 7 years for extension springs, They provide smoother, more balanced door operation, They put less stress on your garage door opener, They're safer because they're contained above the door, away from living spaces
The trade-off? Torsion springs cost more upfront. But that longer lifespan means fewer replacements over the life of your door. A snapped spring repair with a torsion system typically runs higher than extension, but the math works in your favor when you factor in durability.
One critical safety note: torsion springs are under extreme tension. Even when the door is closed, that rod is trying to unwind with hundreds of pounds of force. Never attempt to adjust or replace a torsion spring yourself. I've seen fingers broken, eyes injured, and worse from DIY attempts.
Extension Springs: Budget-Friendly but Higher Maintenance
Extension springs run vertically along both sides of your garage opening, parallel to the door tracks. When the door lowers, these springs stretch. When the door rises, they contract, pulling the door up with your opener's help.
Why choose extension springs?
- Lower replacement cost compared to torsion, Easier installation in tight spaces, Common in older homes built before torsion became standard
The downside is clear: extension springs need more frequent replacement, they're harder on your opener motor, and they create unbalanced lifting forces that can wear out hardware faster. Plus, they're positioned near the living space. If one snaps, that broken coil can whip across your garage dangerously.
Extension springs also require safety cables running through the center of each spring. These cables catch a snapped spring and prevent it from flying across your garage. Over time, those cables fray or snap themselves. It's another maintenance item torsion users don't worry about.

How to Tell Which Type You Have
Walk into your garage and look up. If you see a thick horizontal rod with a large coil wound around it above the center of your door, you have torsion springs. Usually there's one or two of them.
If you see springs running vertically on both sides of the tracks near the top corners of the opening, you have extension springs. Look for a thin cable running through the middle of each spring.

Common Spring Failures in Weldon Homes
Spring failure isn't random. It happens because of wear, improper maintenance, or overuse. A door that opens and closes 5 to 10 times daily will wear springs faster than a door used once or twice daily. Extreme temperature swings in North Carolina winters and humid summers also stress springs.
The most dangerous scenario I see? Homeowners ignoring early warning signs. If your door moves unevenly, rises slowly on one side, or makes a loud bang, your springs are sending distress signals. Continuing to use the door puts pressure on the opener, tracks, and cables. It's a cascade of damage.

When to Call a Professional
You should never attempt spring replacement yourself, period. Spring replacement requires specialized tools, knowledge of load calculations, and safety training. Improper installation can cause the door to fall or operate erratically, putting your car, home, and family at risk.

Frequently Asked Questions
How much does it cost to replace garage door springs in Weldon? Torsion spring replacement typically costs $200 to $400 per spring, while extension springs run $100 to $200 each. Labor, door size, and local service demand affect the final price. Call us for a free estimate.
Can I replace just one spring if the other is still working? No. Springs are matched pairs designed to work together. If one fails, the other is near the end of its life. Replacing both ensures balanced operation and prevents costly opener damage down the road.
How long do garage door springs last? Torsion springs last 7 to 9 years with normal use. Extension springs typically last 5 to 7 years. Frequent use, temperature extremes, and lack of maintenance shorten lifespan significantly.
What happens if a garage door spring snaps while the door is open? The door becomes extremely heavy and may fall suddenly. Safety cables on extension springs catch the door, but it's still dangerous. With torsion springs, the door could drop and damage vehicles or cause injury. Treat a snapped spring as an emergency.
Is it normal to hear a loud bang from my garage? A loud bang often signals a snapped spring. This is not normal and requires immediate professional attention. Do not continue opening and closing the door, as it stresses the opener and other components.
