Garage Door Spring Types in Grand Coulee: Torsion vs. Extension Explained
2026-06-29 7 min read
After 15 years installing and fixing garage doors across Grand Coulee and the surrounding area, I can tell you the biggest confusion homeowners have is understanding which spring type they actually have. The good news: it's not complicated. Your garage uses either a torsion spring or an extension spring. Knowing the difference matters because they fail differently, cost different amounts to replace, and require different safety approaches.
The Two Spring Types: What You're Actually Looking At
When you look above your garage door, you'll see one of two setups.
Torsion springs sit horizontally on a metal rod above the door opening itself. They twist (torsion = twisting) to lift the door. One spring or two springs run parallel to each other, depending on your door weight. Torsion springs are the preferred choice in modern installations because they're more balanced, safer, and last longer.
Extension springs hang vertically on both sides of the door, running along the upper tracks. They stretch to pull the door up. You'll usually see a pulley system and a cable running through the spring. Extension springs are common on older Grand Coulee homes and lighter doors.
The real difference isn't just how they look. It's how they behave when they break.
Why This Matters When a Spring Snaps
A snapped torsion spring won't drop your door on your car. The door stays put because the spring's tension is distributed across the rod, and the door has safety cables running through it. You'll hear a loud bang, notice your door won't open, and you can safely call for help.
An extension spring failure is messier. When one snaps, the door drops hard on the opposite side. The cable whips around. Your opener works harder trying to lift unbalanced weight. This is why extension springs need safety cables too, and why you should never go under a garage door when springs are involved.
I've seen too many DIY attempts go wrong here. Springs store enormous energy. A torsion spring at 250 pounds of tension can snap back and cause serious injury if you don't know what you're doing. That's not a scare tactic; that's 15 years of experience talking.
Cost and Lifespan Differences
Torsion springs last 7 to 9 years with typical use (about 10,000 cycles). Replacement cost runs $200 to $400 per spring, plus labor. If you have two springs, expect $500 to $900 total installed.
Extension springs cost less upfront, usually $100 to $200 per spring, but they wear faster and need replacement every 5 to 7 years. When you factor in labor, you're spending the same money more often.
Here's what homeowners often miss: one snapped spring means the other is failing too. Springs wear together. If you have two extension springs and one breaks, the second is likely months away from snapping. Same applies to torsion springs. Smart approach? Replace both at the same time.

How to Know Which One You Have (And What to Do)
Look at your garage door from inside. If you see a horizontal rod above the opening with a spring wrapped around it, you have torsion. If you see two springs hanging vertically on the sides with cables running through them, you have extension.
Unsure? Take a photo and call us. We can identify your setup, give you an honest estimate, and explain what replacement looks like for your specific door.
Don't attempt removal yourself. The risk isn't worth the savings. We can schedule a free quote and handle the whole job the same day if you need it.
Maintenance and Prevention
Springs fail because they work constantly. Every time your door opens and closes, the springs cycle. Weather in Grand Coulee, especially our harsh winters, speeds up wear. Cold makes metal brittle. Rust eats at the spring.
You can't prevent failure entirely, but you can delay it. Keep the tracks clean. Lubricate moving parts twice a year. Don't leave your door open on windy days. And watch for warning signs: slow opening, jerky movement, or a door that won't stay up halfway.
If your garage door opener has battery backup, you're covered during power outages, but springs are a separate issue. Learn more about openers with backup power and how they interact with spring systems.
The Bottom Line
Torsion springs are better if you're installing new. Extension springs are fine if you already have them and they're working, but plan for more frequent replacement. Either way, when one fails, both need attention.

Frequently Asked Questions
How long do garage door springs typically last? Torsion springs last 7 to 9 years under normal use. Extension springs last 5 to 7 years. Lifespan depends on how often you use the door, local weather, and maintenance. Grand Coulee's cold winters can shorten lifespan by 1 to 2 years.
Can I replace just one spring if the other is still working? Technically yes, but it's not smart. Springs wear together and fail around the same time. Replacing both at once costs slightly more upfront but saves money long-term and prevents a second failure months later.
Is a snapped garage door spring an emergency? Yes. The door won't open, your opener will strain trying, and safety cables can fray. Call a professional immediately. Don't try to force the door or use the opener. It's a same-day service we handle regularly.
Why does my garage door opener sound different when a spring is failing? A weakening spring forces the opener motor to work harder, creating grinding or straining sounds. The door may move slowly or unevenly. These are signs of imminent failure. Get it checked before the spring snaps.
Do I need both springs replaced if only one is visible? Check your spring type. Torsion systems usually have two springs side by side. Extension systems have one on each side. If you see two, both should be replaced together. We'll confirm during our inspection.
