Garage Door Springs in Bow: Torsion vs. Extension and When to Replace
2026-09-10 7 min read
Garage door springs come in two main types: torsion and extension. Torsion springs sit above the door and twist to lift it. Extension springs run along the sides and stretch. Most Bow homes use torsion springs because they're safer and last longer, typically 7 to 9 years with average use.
Understanding Torsion Springs
Torsion springs are the workhorse of modern garage doors. They're mounted on a metal rod that runs horizontally above the door opening. When you open the door, the spring winds tighter, storing energy. When you close it, that stored energy unwinds and helps lower the door smoothly. See our guide on smart garage door technology in bow: security risks you need to know.
The advantage is control. A single torsion spring (or sometimes two on wider doors) distributes force evenly. This means less strain on your garage door opener and a gentler, quieter operation overall. Most people don't realize how much the spring does. Without it, your opener would have to lift 300 to 500 pounds on its own. That's why a snapped spring feels like a total door failure, even though the opener is fine.
Torsion springs do have one downside: replacement isn't a DIY job. The tension is dangerous. A snapped spring can cause serious injury if you're not trained. That's why we recommend calling a professional the moment you suspect spring trouble. Read about garage door opener replacement in bow: when should you upgrade?.
Extension Springs and Older Doors
Extension springs are less common in newer Bow installations but still appear on older garage doors. These springs stretch along the side tracks, one on each side. When the door opens, they extend. When it closes, they contract and help pull the door down.
Extension springs work, but they're messier than torsion. They require safety cables running through them. Without those cables, a snapped extension spring can whip out and damage your door, walls, or worse. They also don't last as long. Expect 5 to 7 years of life, compared to torsion's 7 to 9 years.

Signs Your Springs Are Failing
A snapped spring usually announces itself loudly. You'll hear a loud bang or crack from the garage. After that, the door either won't open at all or feels extremely heavy. Don't force it. A broken spring means your opener is doing 100 percent of the work, and that will burn it out fast.
Other warning signs include a door that creaks or squeaks more than usual, or one that opens or closes unevenly (one side higher than the other). These suggest the spring is losing tension. Call for an estimate before the spring fully breaks. Early replacement is cheaper than dealing with a snapped spring plus opener damage.
We've covered garage door opener problems in detail elsewhere on our site, and springs are often the root cause. If your opener is struggling, the spring may be the real issue.
Spring Replacement Cost in Bow
Torsion spring replacement typically runs $200 to $400 per spring, including labor and the new spring itself. Most single-door residential doors need one spring. Wider doors or heavy commercial applications may need two, which doubles the cost.
Extension springs cost less upfront (around $150 to $300 per spring) but fail more often, so the long-term cost is higher. We've published a detailed breakdown of garage door pricing that covers springs and other repair costs so you can make an informed decision without overpaying.
When you call for a same-day estimate, we'll inspect your door, tell you exactly which springs need replacement, and give you a firm price. No surprises. No upselling.
When to Replace vs. Repair
Here's the honest truth: you can't repair a snapped spring. You replace it. If a spring is showing age but hasn't failed yet, replacement is preventive maintenance. Spending $300 now beats a $600 emergency call at midnight when your door gets stuck in the closed position.
If both springs are original to your door and the door is 8 years old or older, replacing both at once makes sense. They'll fail within months of each other anyway, and you'll save on labor and a second service call.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use, which translates to roughly 10,000 to 20,000 cycles. Extension springs last 5 to 7 years. Lifespan depends on climate, usage frequency, and maintenance.
Can I replace a garage door spring myself? No. Torsion springs are under extreme tension and can cause serious injury or death if mishandled. Always hire a licensed technician. It's not worth the risk or a trip to the emergency room.
Why do garage door springs fail? Springs wear out from repeated opening and closing cycles. Rust, extreme temperature swings (common in Bow winters), and lack of lubrication accelerate failure. Manufacturing defects are rare but do happen.
What's the difference between a snapped and worn spring? A snapped spring breaks suddenly and stops working immediately. A worn spring gradually loses tension, making the door harder to open or causing uneven movement. Both need replacement.
Should I replace both springs at once? If both are original and old, yes. Replacing one while the other is failing means a second service call within weeks. Doing both together saves money and hassle.
