Garage Door Springs in Kent, WA: Torsion vs. Extension Explained

2026-06-05 7 min read

Your garage door springs are the hardest working part of your entire system, and most homeowners never think about them until something snaps. After 15 years on the trucks here in Kent and across the greater Seattle area, I've learned that confusion about garage door springs costs people money and headaches. Let me cut through it: there are two main types (torsion and extension), they fail in predictable ways, and knowing the difference helps you avoid getting overcharged or worse, injured.

Torsion Springs vs. Extension Springs

The spring type your door has depends on your garage setup and how your door was originally installed.

Torsion springs sit horizontally above your garage door opening, wound tight like a clock spring. They use torque (rotational force) to lift the door's weight. Most residential doors in Kent use torsion springs because they're safer, quieter, and last longer. A typical torsion spring lasts 7 to 9 years with normal use, which means roughly 10,000 to 15,000 cycles.

Extension springs run along the sides of your door tracks. They stretch as the door lowers and contract as it rises. You'll see these on older homes or doors with low headroom. They're cheaper upfront but don't last as long. Extension springs typically give you 5 to 7 years before replacement becomes necessary.

The key difference: torsion springs support the door's weight directly. Extension springs work with pulleys and cables, adding complexity and more failure points. If you've got a snapped spring, the type matters when it comes to cost and how quickly we can get you a same-day fix.

Why Springs Fail (And How to Spot It Early)

Springs wear out because they're under constant stress. Every time your door opens and closes, the spring cycles. Weather in Kent doesn't help either. Our humid climate and temperature swings accelerate rust and metal fatigue.

You'll know something's wrong when your door won't open, opens halfway then stops, or sounds like a gunshot when you try to lift it. That bang you hear is usually a snapped spring. Never try to force the door open manually after a spring breaks. The door can weigh 300 to 400 pounds, and without the spring's counterbalance, it's a serious injury risk.

If you notice your door feeling heavier than usual or sagging slightly, that's an early warning sign. Check our post on 5 warning signs your garage door spring needs replacement for a detailed walkthrough of what to watch for.

Spring Replacement Cost and What Affects Price

Spring replacement cost in Kent typically runs between $250 and $500 per spring, depending on type and door size. Torsion springs cost more than extension springs because they're engineered more precisely and last longer. If you have two torsion springs (standard for heavier doors), expect to replace both at the same time. Replacing just one leaves you with uneven lift and premature failure of the remaining spring.

Labor matters too. A straightforward spring swap takes 1 to 2 hours if your door is accessible and the track is straight. Complications like rust, damaged cables, or bent tracks add time and cost.

DIY vs. Professional Repair

I'll be honest: spring replacement is not a DIY job. Torsion springs especially are wound under extreme tension. A slip, a wrong move, or a misaligned tool can cause serious injury or property damage. We've seen too many DIY attempts turn into emergency calls. The cost of a professional repair is worth your safety.

If your door opener is also acting up, springs might not be your only issue. Check our troubleshooting guide for garage door opener problems to rule out other causes before you assume it's all about the springs.

Frequently Asked Questions

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal residential use, translating to roughly 10,000 to 15,000 cycles. Extension springs last 5 to 7 years. Lifespan depends on door weight, frequency of use, and climate conditions.

Can I replace a garage door spring myself? No. Spring replacement requires specialized tools and knowledge. The tension in wound springs, especially torsion springs, can cause serious injury. Always hire a licensed professional for safety and warranty protection.

What's the difference between a snapped spring and a worn spring? A snapped spring fails suddenly and completely, leaving your door immobile. A worn spring weakens gradually, causing the door to feel heavier or sag slightly. Both need professional replacement, but a snapped spring is an immediate emergency.

Why do springs fail in pairs on some doors? Most residential garage doors use two torsion springs (one on each side of the opening) to distribute the load evenly. If one fails, the other compensates, causing uneven wear and premature failure. Replacing both at once prevents future problems and ensures balanced operation.

Does weather affect garage door springs? Yes. Temperature swings, moisture, and rust accelerate spring fatigue. Kent's humid climate speeds up corrosion. Regular maintenance and lubrication can extend spring life, but replacement is inevitable eventually.
