Garage Door Spring Types in Prospect, OR: Torsion vs. Extension Explained
2026-09-04 7 min read
A customer called last Tuesday asking why his garage door wouldn't open. He'd heard a loud bang the night before, and when I rolled up, I found a snapped torsion spring hanging above the door header. He had no idea what it was or how it worked. That's the conversation I have almost weekly here in Prospect, and it's the reason I'm writing this.
Garage door springs in Prospect fall into two main categories: torsion springs and extension springs. Torsion springs sit horizontally above your door and twist to lift it. Extension springs run along the sides of the door tracks and stretch as it opens. Both do the same job. Both fail. But understanding which one you have matters when it's time to repair or replace it.
What Are Torsion Springs?
Torsion springs are the heavier lifters. Literally. They're wound tight and store energy by rotating around a metal shaft. When you open your garage door, the spring unwinds and does most of the heavy lifting. Most residential doors in Oregon use torsion springs because they last longer, operate more smoothly, and handle the weight better over time.
A typical torsion spring lasts between 7 and 9 years with regular use. That's roughly 10,000 to 15,000 cycles. Once one snaps, the other usually follows within months because they wear at the same rate. This is why we almost always replace both springs at the same time, even if only one has failed.
The cost for torsion spring replacement varies, but you're looking at $200 to $400 per spring in most cases, plus labor. If you need same-day service in Prospect, expect to pay a bit more for emergency rates. I always recommend getting an estimate before any work begins so there are no surprises.
What Are Extension Springs?
Extension springs are the older cousin. They sit on either side of the door opening and pull the door up as they stretch. They're cheaper upfront but don't last as long. You'll see them on older homes, lighter single-car doors, or budget installations.
The downside? They're more prone to breaking suddenly. When one snaps, the other side can't hold the weight, and your door could fall. That's why extension spring systems include a safety cable running through the middle of the spring. If it breaks, the cable catches it and prevents it from whipping across your garage. That safety feature has saved countless homeowners from injury.

How to Tell Which Type You Have
Stand in your garage and look above the door. If you see a wound-up metal coil sitting horizontally above the door header, that's torsion. If you see springs running along the sides of the tracks, those are extension springs.
Don't try to fix this yourself. I've been doing this work for 15 years, and springs are one area where DIY repairs go wrong fast. A snapped spring is under extreme tension. Attempting repair without the right tools and knowledge can cause serious injury.
When Springs Fail (And Why)
Springs wear out from use. Dust, rust, and lack of lubrication speed up the process. If you live near Salem or anywhere in Marion County, you know our weather isn't gentle on metal. Rain and temperature swings corrode springs faster than you'd expect.
If you hear a loud bang from your garage, a spring has likely snapped. Stop using the door immediately and call for same-day emergency service. Driving on a snapped spring puts stress on the opener motor and can damage the door itself.
For preventive care, check out our garage door maintenance schedule guide to learn what actually keeps springs healthy longer. Regular lubrication and inspection catch small issues before they become expensive repairs.
Understanding the Cost
Spring replacement isn't the cheapest repair, but it's necessary. Delaying it costs more. A broken spring puts extra strain on your garage door opener, which can fail prematurely if you keep trying to open the door with a bad spring.

Frequently Asked Questions
How long do garage door springs actually last? Torsion springs last 7 to 9 years under normal use, roughly 10,000 to 15,000 open/close cycles. Extension springs wear faster, typically 5 to 7 years. Lifespan depends on frequency of use, maintenance, and local weather conditions in Prospect.
Can I replace just one spring? Technically yes, but both springs wear equally over time. Replacing only one leaves you with mismatched springs that wear at different rates. We recommend replacing both to avoid a second failure within months and keep your door operating safely.
What's the difference in cost between torsion and extension springs? Extension springs cost less upfront, usually $100 to $200 each. Torsion springs run $200 to $400 each. Labor varies, but budget $150 to $300 for professional installation. Torsion systems cost more overall but last longer and operate more smoothly.
Why shouldn't I DIY spring replacement? Springs store enormous tension and can snap suddenly if you don't know what you're doing. Improper installation creates safety hazards and can damage your door or opener. Professional technicians have specialized tools and insurance to handle this work safely.
Is a snapped spring an emergency? Yes. Stop using your door immediately and call for service. Driving on a snapped spring damages the opener and door. Same-day emergency service is available in Prospect to get you back in operation quickly and safely.
