Garage Door Springs in Durham: Torsion vs. Extension (Which Type Do You Have?)
2026-07-18 7 min read
Here's what most homeowners don't realize about garage door springs in Durham: you probably can't identify which type you have without looking directly above your door. That matters because torsion and extension springs fail differently, cost different amounts to replace, and pose very different safety risks. I've responded to calls where homeowners assumed they had one type, then discovered mid-repair they had another. That confusion costs time and money you don't need to waste.
Understanding Your Spring Type
Walk into your garage and look above the closed door. If you see a spring wound tightly around a metal rod running perpendicular to the door, that's a torsion spring. It looks like a coil and sits centered above the doorway. If instead you see two springs mounted horizontally on either side of the door, stretching and contracting as the door moves, those are extension springs.
This distinction matters more than most homeowners think. Torsion springs use rotational force to lift your door. Extension springs use tension and pull. The physics difference means they fail at different rates, require different replacement costs, and create different hazards when they snap.
Torsion springs typically last 7 to 9 years with normal use. Extension springs often fail sooner, sometimes at 5 to 7 years. Both are under extreme tension. A snapped spring doesn't just mean your door won't open. It means 400 pounds of weight suddenly has nothing supporting it.
Why Type Matters for Safety and Cost
I've seen homeowners injured because they didn't understand their spring type. With extension springs, you have safety cables running through them. When the spring snaps, the cable catches the spring and prevents it from whipping across your garage. Without that cable, a spring becomes a projectile. Torsion springs don't have cables, but they're more predictable in failure. They lose tension gradually rather than snapping suddenly.
Cost differences are real too. A torsion spring replacement typically runs more than an extension spring replacement, but torsion springs are more durable overall. You're paying more upfront for a spring that lasts longer.

Signs Your Springs Are Failing Soon
Both spring types show warning signs before catastrophic failure. Listen for a loud bang or crack. If you hear that, a spring has snapped. Your door will feel heavier than normal when opening manually. It may stop partway up and refuse to move. The garage door opener might run but the door stays put.
These symptoms appear weeks or even months before total failure. Don't wait. A weakening spring puts strain on your opener and makes the door dangerous to operate.
If you're uncertain whether you're seeing spring problems or opener issues, our troubleshooting guide covers common garage door problems before you call. It'll help you narrow down what's actually happening.
What Homeowners in Durham and Nearby Areas Should Do
If you've identified your spring type and suspect failure, don't attempt DIY replacement. Springs are under 10,000 pounds of pressure. A slip, a misjudged turn, or an unexpected release can cause serious injury or death. I'm not being dramatic. I've seen it.
Contact a licensed professional who can schedule a free estimate and same-day service. We can assess whether both springs need replacement (they should, even if only one snapped), confirm your spring type, and give you a clear cost estimate before we start work.
Regular maintenance catches spring problems early. Our maintenance schedule guide shows you what to check and when.
Take Action Before Springs Fail
A snapped spring is an emergency. A weakening spring is a warning. The difference between those two states is usually a phone call and a small cost now versus a larger cost and safety risk later.

Frequently Asked Questions
What's the difference between torsion and extension springs? Torsion springs twist around a rod above your door. Extension springs stretch on both sides. Torsion springs last longer (7-9 years), while extension springs typically fail at 5-7 years. Torsion replacement costs more but offers better durability and reliability over time.
How much does spring replacement cost in Durham? Extension spring replacement typically costs $200 to $350 per spring. Torsion spring replacement ranges from $300 to $500 per spring. Both springs should be replaced together even if only one snapped, which doubles the cost but prevents immediate repeat failures.
Can I replace garage door springs myself? No. Springs operate under extreme tension (10,000+ pounds). Improper handling causes serious injury or death. Always hire a licensed professional for spring work, even if you're mechanically skilled.
How do I know if my spring is about to break? Listen for loud banging or popping sounds. Your door feels heavier than normal. It stops partway during opening or closing. The opener runs but the door won't move. Any of these signals immediate professional inspection.
How long do garage door springs actually last? Torsion springs: 7 to 9 years. Extension springs: 5 to 7 years. Lifespan depends on use frequency, climate, and maintenance. Regular lubrication and inspection extend life slightly.
