Garage Door Spring Types in Boerne: Torsion vs. Extension Explained
2026-07-18 7 min read
Here's what most homeowners don't realize about garage door springs: there are two completely different types, and they work in opposite ways. Your Boerne garage door uses either a torsion spring or extension springs, and choosing the right replacement matters more than you'd think. I've been running Boerne Garage Doors long enough to see homeowners waste money on the wrong type. Let me break down the difference so you make an informed decision.
What Are Torsion Springs?
Torsion springs sit above your garage door opening, running horizontally along a metal rod. They twist and untwist as your door opens and closes. Think of them like a wound-up clock spring that releases energy in a controlled way.
Most residential garage doors in the Hill Country use torsion springs because they're durable, precise, and safer than the alternative. A single torsion spring can handle a 7 to 9 year lifespan with normal use. When one snaps, your door becomes dead weight. You'll hear a loud bang, and your opener will struggle or fail entirely.
Torsion springs come in different wire gauges and wind counts. A qualified technician measures your door's weight and calculates the exact spring you need. Get this wrong, and your door either won't open smoothly or you'll burn out your opener motor.
Understanding Extension Springs
Extension springs run vertically on each side of your garage door opening. They stretch and contract as your door moves. Picture a rubber band that extends when you pull it and snaps back to its original length.
Extension springs are cheaper upfront but typically wear faster than torsion springs. They also require safety cables running through them. If an extension spring snaps without those cables in place, the spring can whip across your garage like a dangerous projectile. That's a real safety hazard I take seriously.
Many older Boerne homes still have extension springs. If you're replacing them, I'd recommend talking to us about upgrading to a torsion system instead. Yes, it costs a bit more initially, but the safety and longevity pay off.

How to Know Which Type You Have
Walk into your garage and look above your door opening. If you see a horizontal rod with a spring coiled around it, you have torsion. If you see vertical springs on each side connected by cables, you have extension springs.
Don't try to repair or replace springs yourself. Spring tension is dangerous, and I mean that literally. A snapped spring under load can cause serious injury. When you spot a snapped spring or hear that loud bang, call us for a free estimate instead of attempting a DIY fix.
Our team can usually schedule same-day service in Boerne. We'll assess which spring type your door needs, provide honest pricing, and handle the replacement safely. Check out our guide on when to repair versus replace springs if you're debating whether replacement is worth it.
Cost Differences and What Affects Price
Torsion springs typically cost more than extension springs, but the gap isn't as wide as many homeowners expect. A single torsion spring replacement runs between $200 and $400 depending on your door's weight. Extension springs cost $150 to $300 per side, plus safety cable installation.
The real cost factor isn't the spring type. It's your door's weight. A heavier custom door needs stronger springs and costs more to replace. For detailed pricing specific to your situation, schedule a free quote with us, or call (830) 402-4051.
We also recommend addressing maintenance before springs fail. Regular tune-ups catch wear early and extend spring life. Our maintenance guide covers what actually prevents expensive failures.
Why This Matters in Boerne
Hill Country weather hits garage doors hard. Heat cycles and humidity fluctuations speed up spring wear compared to other regions. Springs that might last 10 years in a stable climate last 7 to 9 years here. That's why I tell every customer to check spring condition annually, especially after our hot summers.
If your door is over 8 years old and you haven't replaced the springs, schedule an inspection soon. A snapped spring during a rainstorm or when you need your car is never convenient.
Your garage door springs are critical infrastructure in your home. Understand which type you have, know the warning signs of failure, and get professional help when springs wear out. That's the honest approach we take at Boerne Garage Doors.

Frequently Asked Questions
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with normal use. Factors like climate, door weight, and usage frequency affect actual lifespan. Annual maintenance helps catch wear before failure.
Can I replace just one spring if the other is fine? Not recommended. Springs wear as a pair. Replacing only one causes uneven door movement and puts stress on the new spring. Replace both at the same time for balanced operation.
What happens if a spring snaps while the door is open? The door becomes immobile. Your opener can't close it, and you can't open it further. Call for emergency service rather than forcing the door, which risks damage to the opener or tracks.
Is upgrading from extension to torsion springs worth it? Yes. Torsion springs last longer, operate more smoothly, and are safer. The upfront cost is higher, but durability and safety make it a smart investment for most Boerne homeowners.
How much does spring replacement cost near me? Cost ranges from $150 to $400 per spring depending on type and door weight. Call (830) 402-4051 for a free estimate tailored to your specific door and spring configuration.
