Garage Door Spring Types in Brightwood: Torsion vs. Extension (And Which You Have)

2026-09-22 5 min read

If you've ever had a garage door that wouldn't budge, a snapped spring is likely the culprit. The two main types of garage door springs work very differently, and knowing which one you have matters when it comes to repair costs, replacement timing, and safety. Here's what every Brightwood homeowner should know.

What Are Garage Door Springs, and Why Do They Matter?

Your garage door weighs 300 to 500 pounds. A spring system counterbalances that weight so your opener doesn't have to do all the heavy lifting. Without springs, your opener burns out in months. With a snapped spring, your door either won't open at all or drops suddenly, which is dangerous for anyone standing nearby.

Springs last 7 to 9 years on average, depending on how often you use your door and how well you maintain it. Most homeowners don't think about springs until one breaks. That's when a same-day service call becomes necessary.

Torsion Springs: The Most Common Type

Torsion springs sit horizontally above your garage door opening, mounted on a metal rod. When the door closes, these springs wind up (torque) and store energy. When you open the door, that stored energy releases and helps lift the weight.

Most newer homes in Brightwood have torsion springs. They're balanced, quiet, and last longer than extension springs. A snapped torsion spring is also more obvious. Your door won't move at all, or it'll move only partway before stopping.

One torsion spring can support the full weight of your door, though many systems use two springs for extra safety and even wear. Replacing a torsion spring costs more than an extension spring because the installation is more technical and requires precise torque calculations.

Why Torsion Springs Fail

Torsion springs fail because metal fatigues over time. Every open and close cycle stresses the spring slightly. After thousands of cycles, the metal weakens and eventually snaps. Rust, poor lubrication, and extreme temperature swings in Oregon winters can speed up failure.

You can't predict exactly when a spring will break, but you can watch for warning signs. A creaking or squeaking sound when the door moves often means the spring is wearing out. If you hear a loud bang, that's usually a snapped spring.

Extension Springs: Older Systems and Budget Options

Extension springs run horizontally along both sides of your garage door opening. Instead of twisting, they stretch and compress like a slinky. When the door closes, the springs extend and store energy. When you open, they contract and help pull the door up.

Older homes sometimes have extension springs. They cost less to replace than torsion springs, but they don't last as long. Extension springs also require safety cables running through the center of each spring. If a spring snaps, the cable catches it and prevents the spring from whipping across your garage.

Without those cables, a snapped extension spring becomes a projectile. That's why safety cables are non-negotiable.

How to Tell Which Type You Have

Look above your garage door opening. If you see a horizontal spring wound around a metal rod in the center, you have torsion springs. If you see two springs running along the left and right sides of the opening, you have extension springs.

Don't try to touch or adjust springs yourself. They're under extreme tension and can cause serious injury if mishandled. Get a technician to inspect them and provide an estimate.

When to Replace Your Springs

Most springs need replacement when they snap. Waiting is risky because a broken spring puts stress on your opener and can damage the door itself. Some homeowners choose to replace both springs at once, even if only one broke. This prevents a second breakdown weeks later and keeps your door balanced.

Our previous post on spring replacement timing and cost savings covers how to budget for this repair and when replacement makes financial sense.

If you want to avoid emergency calls altogether, regular maintenance catches worn springs before they fail. We've written about the tune-up that stops emergency calls, which includes spring inspection.

Getting an Accurate Cost Estimate

Spring replacement cost depends on whether you have torsion or extension springs, how many springs you need replaced, and your local labor rates. A broken spring in Brightwood typically requires same-day service, and estimates vary based on the type and complexity of your system.

Frequently Asked Questions

How long do garage door springs last? Torsion and extension springs last 7 to 9 years with normal use. Heavy use (opening and closing multiple times daily) shortens that lifespan. Poor lubrication and rust can cut it down to 5 years.

Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if they snap during removal. Always hire a licensed technician to handle spring replacement safely.

How much does a snapped spring cost to fix? Torsion spring replacement typically costs more than extension spring replacement because the installation is more precise. Your technician will provide an estimate after inspecting your door and determining the spring type.

What happens if I ignore a broken spring? Your garage door won't open, or it'll open only partially. Continuing to use a broken spring damages your opener and can cause the door to fall unexpectedly, creating a safety hazard.

Are both springs failing at the same time normal? Not always, but it's common. If one spring has reached the end of its lifespan, the other is likely close behind. Many homeowners replace both springs at once to prevent a second emergency call.
