How Do Garage Door Springs Work? A Keno Technician Explains
2026-05-24 7 min read
Your garage door weighs 300 to 500 pounds. Without springs, you'd need the strength of a linebacker to open it by hand. That's the job of garage door springs: they counterbalance the weight so your opener can lift the door effortlessly. Let me walk you through how they actually work and why understanding them matters for your Keno home.
The Two Types of Springs and How They Differ
There are two main spring systems in residential garage doors: torsion springs and extension springs. Each works differently, and knowing the difference helps you spot trouble early.
Torsion springs sit above the door, running horizontally across the opening. When your door closes, the springs wind up and store energy. When you open the door, that stored energy unwinds and helps lift the weight. Think of it like winding up a toy: the tighter you wind, the more energy it releases. Most modern garages in Keno and the surrounding area use torsion springs because they're more reliable and last longer (typically 7 to 9 years with normal use).
Extension springs hang on both sides of the door tracks. As the door lowers, these springs stretch like a rubber band. When you open the door, they contract and pull upward. They work alongside the torsion system or alone, depending on your setup. Extension springs tend to wear out faster than torsion springs and need more frequent inspection.
Why Springs Fail and What Happens When They Do
Springs wear out from constant use. Every time you open and close your door, the spring cycles. Over 7 to 9 years, you're looking at roughly 1,500 to 2,000 cycles per spring. Metal gets tired. Rust from Oregon's moisture accelerates failure. Temperature swings stress the metal too.
A snapped spring is a safety hazard and a real problem. Your door won't open, or it'll come down hard and fast. Never try to force it open or operate the door manually after a spring breaks. The door is heavier than you think, and you could get seriously hurt. If you've got a snapped spring, call a professional.

The Role of Your Garage Door Opener
Your opener doesn't lift the door by itself. The springs do most of the work. Your opener's motor just guides and controls the descent. This is why a broken spring makes your door feel impossibly heavy even with the opener running. The motor can't compensate for a non-functional spring system.
When springs are worn but not completely broken, your opener has to work harder. You'll hear the motor strain, see the door move slower, or notice the door jerks. These are early warning signs. Replacing worn springs before they snap saves you money and prevents emergency repairs.
Spring Maintenance and Inspection
You can't oil your way out of spring failure, but you can spot problems early. Walk out to your garage once a quarter and look at the springs above or beside the door. Are they visibly cracked or split? Does the door move smoothly and evenly? Any rust or discoloration? Listen too. A healthy door opens quietly. A grinding or squeaking noise often points to spring or track issues.
Don't attempt to adjust or replace springs yourself. They're under extreme tension. If they slip, you could lose a finger or worse. Let trained technicians handle it. When you're ready for an inspection and estimate, schedule a free quote with us and we'll assess everything.
Cost Expectations in Keno
Spring replacement isn't cheap, but it's not a shock either. Most homeowners spend $200 to $400 for a single torsion spring replacement, including labor. Extension springs run a bit less. If both springs need replacing (which is common because they wear together), budget $400 to $600. An estimate is free and takes 15 minutes. We'll tell you exactly what you need and what it costs before we touch anything.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with average residential use (1,500 to 2,000 cycles). Extension springs often wear out sooner. Harsh weather, frequent use, and poor maintenance can shorten lifespan.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if they slip or break during removal. Always hire a licensed technician to handle spring replacement or repair work.
What does a snapped spring sound like? A loud bang or crack, like a gunshot, followed by the door refusing to open or dropping suddenly. If this happens, stop using the door immediately and call for professional help right away.
Why do both springs need replacing at the same time? Springs wear at the same rate since they handle equal load. If one fails, the other is near failure too. Replacing both at once prevents a second breakdown weeks later and ensures balanced door operation.
How much does a spring replacement cost near me? In Keno, expect $200 to $400 for one torsion spring with labor, or $400 to $600 for both. Call (541) 329-3070 for a free estimate tailored to your specific door and springs.
