Garage Door Spring Types in Edmonds: Torsion vs. Extension Explained
2026-06-12 7 min read
After 15 years installing and repairing garage doors across Edmonds and the surrounding communities, I've learned one thing: most homeowners don't know the difference between a torsion spring and an extension spring until one snaps. Let's cut through the confusion. Your garage door uses one of these two types, and knowing which you have could save you time, money, and a potential injury.
What's the Difference Between Torsion and Extension Springs?
Torsion springs sit horizontally above your garage door, running across the header beam. They twist and unwind to lift your door. Extension springs hang vertically on each side of the door frame, stretching and contracting to provide lift. That's the basic split, but the differences go deeper.
Torsion springs are heavier duty. They're built to last 7 to 9 years under normal use. A standard two-car garage door uses one torsion spring rated for about 10,000 cycles, which translates to roughly four to seven openings and closings per day. Extension springs, by contrast, typically handle 15,000 to 20,000 cycles total, but they wear out faster because they're under constant tension even when the door is closed.
In Edmonds, where we get significant moisture and temperature swings, torsion springs tend to perform better long term. The design keeps them more protected from weather, and they distribute load more evenly across the door.
Why Torsion Springs Are More Common
Most newer homes and quality installations use torsion springs. They're safer, quieter, and more reliable than extension springs. When a torsion spring fails, your door simply won't open or close. When an extension spring snaps, the cable can whip around and cause injury or property damage.
If you have an older home or a budget installation, you might have extension springs. That's not a deal-breaker, but you should know the risks. Many homeowners I work with in the greater Seattle area have extension springs on their older doors, and they're surprised to learn they're working with an outdated system.
Here's what matters: whether you have torsion or extension springs, they're under enormous tension. I've seen firsthand what happens when someone tries to DIY a snapped spring repair. It's not worth it. The spring can uncoil with force equivalent to a loaded gun. Leave this work to professionals.

When a Spring Snaps: What Happens Next
A snapped spring is one of the most common garage door emergencies I handle. The door becomes extremely heavy, impossible to open by hand, and your opener will strain trying to lift dead weight. Some homeowners hear a loud bang or pop, others just find their door stuck.
If you're experiencing a snapped spring right now, don't force the door open. Call for professional repair immediately. We can provide an estimate for spring replacement and get your door working again the same day in most cases.
The cost of spring replacement varies based on whether you need torsion or extension springs, the door size, and whether additional components like cables need replacement.

Spring Maintenance: Extend Their Life
You can't prevent springs from eventually wearing out, but you can extend their lifespan. Keep your garage door balanced and aligned. A door that binds or sticks puts extra stress on springs and shortens their life by years. Regular lubrication of hinges, rollers, and bearings also reduces strain on the spring system.
If you haven't had your garage door opener and spring system serviced recently, now's a good time. We offer comprehensive garage door opener maintenance in Edmonds that includes spring inspection and safety checks.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with average use. Extension springs often wear out faster, typically in 5 to 7 years. Lifespan depends on usage frequency, climate, and maintenance.
Can I replace just one spring? It's best to replace both springs at the same time, even if only one is broken. Springs wear as a pair, and replacing both prevents an imbalance that stresses your door and opener.
Why is spring replacement expensive? Professional spring replacement requires specialized tools and expertise. The labor cost reflects the safety risk and precision involved. A garage door spring under tension can cause serious injury if mishandled.
How do I know if my spring is about to fail? Listen for squeaking or creaking sounds during operation. The door may become harder to open, or you'll notice it closing faster than it opens. If you spot rust or visible wear, have it inspected soon.
What's the difference in price between torsion and extension springs? Torsion springs generally cost more upfront but last longer. Extension springs are cheaper initially but require more frequent replacement. Over ten years, torsion systems often cost less overall.
