Garage Door Spring Types in Bulverde: Torsion vs. Extension (Which Costs Less?)
2026-08-21 7 min read
Most people don't think about their garage door springs until something goes wrong. Then suddenly you're staring at a door that won't budge and wondering if repair costs will drain your wallet. The type of spring your door uses matters more than you think.especially when budget time comes around.
Your garage door has either a torsion spring or an extension spring. That single difference affects repair cost, lifespan, safety, and whether you can handle the fix yourself (spoiler: you shouldn't). Understanding which one you have and what it costs to replace will save you hundreds in unnecessary spending.
How Torsion and Extension Springs Work Differently
Torsion springs sit above your garage door opening, running horizontally across the header. They twist and unwind to lift your door. Think of them like a wound-up spring in a mechanical clock. As the door closes, the spring winds tighter, storing energy. When you open the door, that stored energy releases, making the heavy lift effortless.
Extension springs mount on both sides of the door, above the horizontal tracks. They stretch and contract like a rubber band. As your door rises, the springs extend. When it closes, they compress back. Extension springs rely on pulleys and cables to transfer that motion to the door itself.
The big difference: torsion springs handle the work directly through rotation. Extension springs do it indirectly through tension and pulleys. That distinction affects everything from cost to safety.
Cost Comparison: Torsion vs. Extension
Torsion springs typically cost more upfront but last longer. Most quality torsion springs run 7 to 9 years before needing replacement. Extension springs? They usually give you 5 to 7 years. If you're looking at total cost of ownership, torsion often wins despite the higher initial price.
A snapped spring in Bulverde means your door becomes a heavy, immovable object. Replacing a single torsion spring runs $150 to $300 on average. Extension spring replacement is usually $100 to $200 per spring. But here's the catch: most doors have two extension springs, so you're replacing both. Replacing one extension spring creates imbalance and accelerates wear on the other.
Torsion spring doors typically have just one spring doing all the work. When it fails, you replace one component. That efficiency translates to lower overall maintenance cost over your door's lifetime.

Which Type Is Safer?
Extension springs are the safety worry. When a spring snaps, those cables and pulleys become flying metal hazards. You've probably heard stories about springs becoming projectiles. That's almost always an extension spring failure.
Torsion springs are contained above the door, so if they snap, the risk of injury drops significantly. Your door might be stuck, but you're not dodging shrapnel. For homes with children or pets, this matters. For any home, really.
Both types require professional replacement. DIY spring repair is genuinely dangerous. The tension stored in a compressed spring can cause serious injury or death if mishandled. Call a pro. It's not worth the hospital visit or worse.
Identifying Your Spring Type (And When to Call for Help)
Look above your garage door. Is there a spring running left to right, directly above the opening? That's torsion. Do you see springs on each side of the door, running parallel to the horizontal tracks? That's extension.

Frequently Asked Questions
How long do garage door springs actually last? Torsion springs last 7 to 9 years with normal use. Extension springs typically last 5 to 7 years. Lifespan depends on door cycles, climate, and maintenance. Bulverde's heat and humidity can shorten lifespan slightly.
Can I replace just one extension spring? Technically yes, but it's a poor choice. The remaining spring will fail within months because it carries uneven load. Replace both extension springs together. It costs more upfront but saves money long-term.
Why shouldn't I fix a snapped spring myself? Spring tension stores hundreds of pounds of force. Mishandling it can cause severe injury or death. Professional tools and experience prevent accidents. It's not worth the risk or hospital bills.
Do torsion springs work better than extension springs? Torsion springs last longer, run safer, and require less maintenance. Extension springs cost less initially but need more frequent attention. For most Bulverde homeowners, torsion is the better long-term choice.
