Garage Door Spring Types in Dairy: Torsion vs. Extension (Which Do You Have?)
2026-08-04 7 min read
Your garage door probably has one of two spring types: torsion or extension. Knowing which one you've got matters because they fail differently, cost different amounts to replace, and require different safety precautions. I've spent 15 years pulling snapped springs out of garages across Dairy and the surrounding area, and the homeowners who understand this distinction make smarter decisions fast.
Torsion Springs: What You're Most Likely Running
Most homes built in the last 30 years use torsion springs. These are the heavy-duty coils that sit horizontally above your garage door opening, right where the door stops when it's closed. They twist and untwist thousands of times, storing and releasing energy to counterbalance the weight of the door. See our guide on garage door openers in dairy: what homeowners don.
Torsion springs are the premium option. They last 7 to 9 years on average, they're safer (they don't fly across the garage when they fail), and they handle the lifting more efficiently. The tradeoff: they cost more upfront and require a skilled technician to install or replace.
When a torsion spring snaps, the door suddenly feels heavy. Sometimes it won't open at all. You might hear a loud bang before you notice the problem. This is the moment many people call us for same-day service. Read about garage door safety in dairy: what every homeowner must know.
Extension Springs: The Older, Budget Approach
Extension springs hang vertically on both sides of the door opening, usually inside a cable track system. When the door closes, these springs stretch. When it opens, they contract and help lift the weight.
Extension springs are cheaper to install originally, which is why older homes often have them. But they have drawbacks. They wear out faster (typically 5 to 7 years), and when one fails, the other side is usually close behind. More importantly, if the cable snaps, the spring can whip across the garage like a weapon.
Safety is why we always recommend extension spring systems include safety cables. Those cables wrap around the springs and contain them if something fails. Even with cables, though, extension springs require more caution during repairs.
Why This Matters Right Now
If you're experiencing trouble opening or closing your door, or if you hear creaking and grinding sounds, your springs might be near the end of their service life. Learn more about the real cost of a snapped spring and what repairs actually run.

The type of spring you have determines how we approach the problem. With torsion springs, we can often replace just the failed spring and keep your system balanced. With extension springs, we typically recommend replacing both sides at once, even if only one has snapped. It's safer and more cost-effective long term.
How to Tell Which Type You Have
Walk into your garage and look up at the door frame. Do you see a horizontal coil above the door? That's torsion. Do you see springs hanging on cables on each side? That's extension.
Not sure? Take a photo and schedule a free estimate. We'll identify your system and give you a clear cost breakdown. Many homeowners are surprised how affordable a spring replacement can be when you know exactly what needs doing.
The Installation and Safety Factor
Never attempt to replace garage door springs yourself. The tension in these springs is enormous. A torsion spring can unwind with enough force to cause serious injury. Extension springs, with their cables, carry similar risk.
Dairy Garage Doors handles spring installation the right way. We use proper tools, we test the balance, and we make sure your door tracks smoothly after the work is done. That's not just about comfort; it's about safety for your family and protecting your vehicle.

Maintenance Keeps Springs Alive Longer
Springs fail because they're metal under constant stress. You can't prevent failure entirely, but you can slow it down. Regular lubrication, gentle use (don't slam the door), and keeping the door balanced all extend spring life by a year or more.
Our maintenance guide walks through budget-friendly steps that pay for themselves in longevity.
Springs fail. It happens to every garage door eventually. The difference between a smooth repair and a stressful emergency is knowing what you have and calling the right person when trouble starts. We're ready to help.

Frequently Asked Questions
How long do garage door springs typically last? Torsion springs last 7 to 9 years with normal use. Extension springs wear faster, usually 5 to 7 years. Lifespan depends on how often you open and close the door and how well you maintain lubrication.
Can I replace just one spring if the other is still working? With torsion springs, yes, though we check the other side carefully. With extension springs, we recommend replacing both simultaneously because they wear together and one failure usually means the second is near failure.
What does a garage door spring replacement cost? Torsion spring replacement runs $200 to $400 per spring plus labor. Extension springs cost less per spring but often require replacing both. Call (541) 722-2124 for a specific estimate based on your door and spring type.
Is it safe to use my garage door if one spring is broken? Not safely. A broken spring throws the load entirely on the opener and the remaining spring, which can damage both and create safety hazards. Don't use the door until springs are repaired.
Why do springs break suddenly instead of showing warning signs? Springs fail from metal fatigue. Tiny cracks develop internally over years until the metal finally snaps under stress. Regular maintenance can help you catch older springs before complete failure, but some breaks happen without warning.
