Garage Door Spring Types in Lincoln: Torsion vs. Extension Explained

2026-09-21 7 min read

A customer called last Tuesday morning saying her garage door wouldn't open. She'd heard a loud bang the night before. When we arrived, the problem was clear: a snapped torsion spring. She asked why it broke and what the difference was between torsion and extension springs. Good questions. Knowing the difference helps you understand what failed, why it matters, and what the repair actually costs.

Torsion Springs: The Workhorse Behind Your Door

Torsion springs are mounted horizontally above your garage door opening, wound tightly around a metal shaft. When you open the door, these springs unwind to counterbalance the door's weight. They work by twisting and rotating, not by stretching. See our guide: Garage Door Spring Tension in Lincoln.

Most residential doors in Lincoln use torsion springs because they're more durable and precise. A typical torsion spring lasts 7 to 9 years with normal use. They handle the opening and closing cycle better than extension springs, and they fail more predictably. When a torsion spring snaps, the door won't open at all, which is actually safer than an extension spring failure.

The tradeoff? Torsion springs cost more to replace than extension springs, but they're worth it for most homes. See our guide: Garage Door Spring Emergency in Lincoln? Here.

Why Torsion Springs Fail

Springs fail when they reach the end of their cycle life, not because of a defect. Every opening and closing counts as one cycle. A door that opens and closes three times daily completes about 1,100 cycles per year. Over 7 to 9 years, that adds up. Eventually, the metal fatigues and snaps. Rust from humidity in the garage also weakens springs faster, especially in older homes.

Extension Springs: The Budget Alternative

Extension springs run along the sides of your garage door opening, one on each side. They stretch and contract to lift the door. You'll see them connected to pulleys and cables that run the length of the opening.

Extension springs are less expensive upfront than torsion springs, which is why some builders use them on budget installations. However, they don't last as long. They typically reach the end of life in 5 to 7 years. When one snaps, the other side must carry the full load, creating an unbalanced opening that stresses your garage door opener and can damage the door itself.

Extension springs also pose a safety risk. If a cable breaks along with the spring, the door can fall suddenly.

Identifying Which Type You Have

Look above your garage door opening. If you see a thick coil of metal wound tightly around a horizontal shaft in the center, you have torsion springs. If you see springs running vertically along both sides of the opening with pulleys and cables, those are extension springs.

Not sure? Don't guess. A snapped spring is dangerous to handle yourself, and misidentifying the type could lead to ordering the wrong part. That's why we recommend calling for a same-day estimate so a professional can assess what you're working with and give you accurate pricing.

Cost Differences Matter

Torsion spring replacement typically costs more than extension spring replacement, partly because the installation is more involved and requires specialized tools. The spring itself is more expensive too. But here's the real cost consideration: torsion springs last longer and fail less catastrophically., you might replace an extension spring twice and a torsion spring once. The math often favors torsion.

When to Call a Professional

Never attempt to adjust, repair, or replace a garage door spring yourself. These components are under extreme tension. A snapped spring can cause serious injury. Even a torsion spring that hasn't failed yet is dangerous if you don't know how to handle it safely.

If you suspect a spring problem, stop using the door and contact us for a repair appointment. We can diagnose whether your issue is a snapped spring, a tension adjustment, or something else entirely. Many spring problems look similar but require different solutions. A professional inspection takes the guesswork out.

Frequently Asked Questions

How long do garage door springs last? Torsion springs typically last 7 to 9 years under normal use. Extension springs last 5 to 7 years. Lifespan depends on cycle frequency, humidity, and maintenance. Springs don't wear out gradually; they fail suddenly once cycle life is exhausted.

Can I replace just one spring? If you have two extension springs and one breaks, both should be replaced together. The remaining spring will wear out soon, and replacing them in pairs prevents imbalance. For torsion springs, you typically have one spring, so you replace the one.

Why is spring replacement so expensive? Spring replacement requires specialized tools, knowledge of proper tension, and safety precautions. An improperly installed spring creates safety hazards and damages your door opener. Professional installation ensures the job is done right the first time.

What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly and completely. A worn spring is one that has reached the end of its cycle life and will break soon. You can't tell by looking; only a technician can assess remaining lifespan.

Should I upgrade to a torsion spring if I have extension springs? If your extension springs are failing frequently, upgrading to torsion springs makes financial sense over time. Torsion springs last longer, are safer, and provide smoother operation. We can provide an estimate for the conversion.
