A customer called last Tuesday asking why their spring replacement estimate seemed high. When I asked which type of spring they had, they went quiet. Turns out they didn't know the difference between torsion and extension springs. That confusion happens more often than you'd think. Understanding which spring type your garage door uses matters because the cost, installation complexity, and safety profile differ significantly. Here's what every Cougar homeowner should know.
Torsion springs mount horizontally above your garage door opening. They twist and untwist as your door moves up and down, storing and releasing rotational energy. Think of them like a tight coil that winds up when you open the door and releases that stored tension to help close it.
Most residential doors built after 1990 use torsion springs. They're the industry standard because they're safer, more durable, and handle the door's weight more predictably. A torsion spring typically lasts 7 to 9 years with normal use, assuming your door opens and closes roughly 3 to 5 times daily.
The tradeoff: torsion spring replacement costs more than extension springs. Labor is more technical because the springs work under extreme tension. We need specialized tools and experience to safely replace them.
Extension springs run vertically along both sides of your door opening. Instead of twisting, they stretch and contract like a traditional coil spring. When you open the door, they extend. When it closes, they contract and help pull the door down.
Older homes in the Cougar area and throughout Washington often have extension springs. They're cheaper upfront and simpler to install. But they come with a safety risk: if an extension spring snaps, the door can fall without a safety cable to catch it. That's why modern building codes favor torsion springs for residential use.
If you have extension springs, they should have safety cables running through them. These cables prevent the spring from whipping across your garage if it breaks.
Walk into your garage and look above the door. If you see a single horizontal spring running across the top (perpendicular to the door panels), you have a torsion spring. If you see two springs running vertically along the left and right tracks, those are extension springs.
Don't touch the springs themselves. They're under extreme tension and can cause serious injury. Just identify which type you have, then call us for an inspection.

Torsion spring replacement generally runs $200 to $400 per spring, plus labor. Extension springs cost less in parts (around $100 to $200) but the labor time is similar because the job still requires precision.
The real cost variable isn't the spring type itself. It's whether your door has a snapped spring right now. A functioning spring can be replaced during normal business hours. A snapped spring that leaves your door stuck creates an emergency situation, which affects scheduling and availability.
We always provide an honest estimate before starting work. You'll know the total cost upfront, no surprises. If you're curious about what you'll actually pay in Cougar, our cost breakdown guide covers real pricing for both spring types.
Knowing your spring type helps you plan maintenance. Torsion springs need periodic lubrication and inspection. Extension springs need the same attention, plus you should verify those safety cables are intact.
If you suspect spring failure, don't ignore it. Spring failure warning signs like a loud bang, a door that won't open, or uneven movement mean one or both springs have likely failed. That's when you need us quickly.

Your door's spring type determines how we approach the repair. Torsion springs require specialized equipment and training. Extension springs are simpler mechanically but still demand careful work.

Can I replace a garage door spring myself? No. Both torsion and extension springs operate under 200+ pounds of tension. A slip or improper installation can cause serious injury or property damage. This is a job for trained professionals with the right tools.
How long do garage door springs last? Torsion springs typically last 7 to 9 years. Extension springs may last 5 to 7 years. Lifespan depends on usage frequency and maintenance. Regular lubrication extends spring life significantly.
What's the difference in safety between the two types? Torsion springs are safer by design because they're enclosed and their failure is more predictable. Extension springs require safety cables to prevent the spring from whipping if it breaks. Both are safe when properly maintained.
How much does spring replacement cost near me? Torsion spring replacement costs $200 to $400 in parts plus labor, roughly $300 to $500 total per spring. Extension springs cost less in parts but similar labor time. We provide exact estimates after inspection.
Should I replace both springs if one is broken? Usually, yes. If one spring has failed, the other is near the end of its life. Replacing both at once prevents a second failure weeks later and saves on labor costs overall.
