Serving Bellevue, we see this problem again and again: homeowners don't know which type of garage door spring system they have until one fails catastrophically. Torsion and extension springs do the same job.counterbalancing your door's weight so the opener doesn't burn out.but they fail differently and cost differently to replace. Understanding which one you own could save you hundreds of dollars and keep your family safer.
Torsion springs wind around a horizontal rod mounted above your garage door opening. They twist (torque) to store and release energy. Most modern residential doors in Bellevue use torsion springs because they're more durable, safer, and quieter. A typical torsion spring lasts 7 to 9 years with normal use.
Extension springs hang vertically on either side of the door track. They stretch and contract to lift the door. Older homes and lighter-duty doors often have extension springs. They're cheaper upfront but wear faster and pose a higher safety risk if they snap.
The easiest way to identify yours: look inside your garage when the door is closed. If you see a thick metal rod running horizontally above the door with coils wrapped around it, that's torsion. If you see springs running parallel to the tracks on both sides, those are extension springs.
A snapped torsion spring usually gives you a warning. The door becomes harder to open, you hear grinding or creaking, and the opener may struggle. That's your cue to call for help before total failure.
A snapped extension spring? It can whip violently when it breaks. We've seen injuries happen. And because extension springs work in pairs, losing one puts all the load on the other, causing it to fail within days. You could find yourself locked out or, worse, with a door that falls unexpectedly. Learn more about what happens when springs fail in our guide to snapped garage door springs in Bellevue and what to do.
The cost difference is real too. Torsion spring replacement typically runs higher than extension springs because installation requires specialized tools and expertise. But extension springs fail more often, so you might replace them twice in the time you replace torsion once.

If your door is currently working, don't replace springs preemptively. But if you're facing a repair or replacement, your existing spring type usually stays the same. The manufacturer and door size determine which system makes sense.
However, upgrading from extension to torsion springs during a replacement is worth considering. Yes, the initial estimate will be higher. But torsion springs are safer, last longer, and put less stress on your opener. Redmond and Sammamish homeowners often ask us about this upgrade when they're already investing in repairs.

Springs fail from normal wear, but poor maintenance accelerates failure. Rust, dirt buildup, and lack of lubrication all shorten lifespan. A regular inspection catches rust early and keeps components moving smoothly.
Our garage door tune-up and inspection service includes spring assessment, lubrication, and balance checks. Catching a weak spring before it snaps means you avoid emergency repairs and keep your door operating safely.
Never attempt to replace or repair garage door springs yourself. Torsion springs are under extreme tension. Releasing that tension without proper tools can cause serious injury or death. Even extension springs, while less dangerous, require skill to install safely and correctly.
If your door won't open, opens unevenly, or you hear a loud crack or bang, stop using it and contact us for emergency service. A broken spring won't repair itself, and using the door risks further damage or injury.

How long do torsion springs last compared to extension springs? Torsion springs typically last 7 to 9 years. Extension springs often fail within 5 to 7 years because they work harder and handle stress less efficiently. Both depend on door use frequency and maintenance.
Can I replace just one spring if the other is still working? Extension springs should always be replaced in pairs, even if only one snapped. The remaining spring is likely near failure and will break soon after, leaving you stranded again. Torsion springs are single units, so you replace the one that failed.
Why does a snapped spring make my door stuck? Springs counterbalance the door's weight so the opener doesn't have to lift 300+ pounds alone. Without a functioning spring, the opener simply can't move the door. It's a safety feature and a mechanical reality.
What's the average cost difference between torsion and extension spring repair? Torsion spring replacement typically costs more due to specialized tools and labor complexity. Extension springs cost less to install but fail more often. Over time, torsion often saves money despite higher per-repair costs.
Should I upgrade from extension to torsion springs during a repair? If you have extension springs and they fail, upgrading to torsion is worth considering. You'll pay more upfront but gain safety, longevity, and reduced future repair frequency. Get an estimate from our team to compare your options.
