Garage Door Springs in Ronda, NC: Torsion vs. Extension Explained
2026-07-25 7 min read
Garage door springs do one job: counterbalance the weight of your door so the opener doesn't burn out in a week. There are two types in most homes, and knowing which one you have saves money and headaches. Let's cut through the confusion about garage door springs so you understand what's holding your door up and what happens when it fails.
Two Types of Springs: Know What You Have
Your garage door uses either torsion or extension springs. Torsion springs sit horizontally above your door opening on a metal rod. Extension springs hang vertically on each side of the door. Both do the same job, but they work differently and fail differently.
Torsion springs are the heavier hitter. They're wound tight and store energy like a coiled snake. When you open the door, that stored energy releases and lifts the weight. Most modern doors use torsion because they last longer, run quieter, and are safer when they break (they don't snap violently across the garage). Extension springs stretch as the door lowers, then contract to pull it back up. They're cheaper upfront but wear faster because they work harder on each cycle.
The spring you have depends on your door's age and design. Homes built after the 1990s almost always have torsion. Older homes might have extension springs. Either way, they wear out. Most springs last 7 to 9 years with normal use, roughly 10,000 to 15,000 cycles.
What Happens When a Spring Snaps
A snapped spring isn't a slow leak. It's sudden and complete. One day your door opens fine; the next day it won't budge or drops hard. You'll hear a loud bang (sometimes a crack or pop) coming from above the door when it fails.
When a spring breaks, the full weight of your door crashes onto the opener. The opener wasn't designed to lift the door alone. It'll strain, overheat, and burn out within days if you keep trying to use it. That's why we always recommend stopping use immediately and calling for repairs.
A snapped torsion spring costs more to replace than extension because the part itself is pricier and installation takes longer. Extension spring replacement runs cheaper but the labor is similar. We'll give you a same-day estimate over the phone so there are no surprises.
The Cost of Spring Replacement
Spring replacement cost depends on type, door weight, and whether both springs need replacing. A single torsion spring replacement typically runs higher than extension, but both fall in a predictable range. Labor usually costs more than the part itself because the job requires precision and safety equipment.
Here's the thing: if one torsion spring fails, the other is close behind. They age together and wear at the same rate. Replacing both at once is smarter than waiting for the second one to snap in three months. Same logic applies to extension springs. Most of our customers choose to replace both and avoid a second service call.

Why Professional Installation Matters
Springs are under extreme tension. A torsion spring rod can spin and cause serious injury if you slip. Extension springs can snap back and cut you. This isn't a DIY job, no matter how handy you are.
Professional installation means the springs are wound to exact specs for your door's weight. Too loose and they won't lift the door. Too tight and they fail faster. We measure, calculate, and install with the right tools. When Garage Door Ronda handles your spring replacement, you get it right the first time.
We also inspect the rest of your system while we're there. A snapped spring often means your cables, pulleys, or rollers took extra stress. Catching those problems early prevents bigger repairs down the road. If you want to stay ahead of issues, read our guide on preventing costly garage door repairs before they start.

Frequently Asked Questions
How long do garage door springs typically last? Most springs last 7 to 9 years with normal residential use, or about 10,000 to 15,000 cycles. Frequency of use, climate, and maintenance affect lifespan. Springs don't wear gradually; they fail suddenly.
Can I replace just one spring if the other is still working? Not recommended. Both springs age together and wear at the same rate. Replacing only one means the second will fail soon after, costing you another service call. Replacing both together is more economical long term.
What's the difference between torsion and extension springs? Torsion springs sit horizontally above the door and store energy when wound. Extension springs hang on the sides and stretch as the door lowers. Torsion springs last longer, run quieter, and are safer when they break.
How much does spring replacement cost? Cost varies by spring type, door weight, and labor rates. Single torsion replacement typically runs higher than extension. We provide a same-day estimate over the phone with no obligation. Call 1-336-490-5221 for pricing.
Is it safe to use my garage door if a spring is broken? No. A broken spring throws all weight onto the opener, which will overheat and fail. Stop use immediately and contact a professional. Trying to force a broken-spring door can cause injury or damage the opener beyond repair.
