Garage Door Springs in South Houston: Torsion vs Extension (What You Actually Need)
2026-09-15 5 min read
Here's what most homeowners don't realize about garage door springs: there are two completely different types, they work in opposite ways, and picking the wrong replacement can cost you money or create a safety hazard. If you own a home in South Houston or the surrounding area, understanding torsion springs versus extension springs isn't just trivia. It's the difference between a smooth, safe garage door and one that could fail without warning.
The Two Types of Garage Door Springs
Your garage door is heavy. A standard single-car door weighs 300 to 400 pounds. The springs do almost all the lifting work, not your opener. That's why spring failure stops your door cold.
Torsion springs wind up like a clock spring above your garage door opening. When the door closes, tension builds. When you open it, that stored energy unwinds and helps lift the weight. Torsion springs are mounted horizontally on a shaft, usually centered above the door frame.
Extension springs run vertically alongside your door tracks. They stretch and contract as your door moves up and down, working like the springs on a trampoline. When the door lowers, the springs extend. When it opens, they contract and pull upward.
Most homes in South Houston use torsion springs because they're more durable and balanced. Extension springs show up in older homes or on lighter doors. Both work, but they're not interchangeable.
Why the Type Matters for Your Home
Torsion springs last longer. A quality torsion spring cycles 7 to 9 years under normal use before wearing out. Extension springs typically last 4 to 7 years. That's a real difference in your wallet over time.
Torsion springs also distribute force more evenly across your door. Your door opens and closes smoothly, and the opener doesn't have to work as hard. Extension springs can create uneven lift, which puts extra strain on your opener motor and rollers.
Safety is the biggest factor. A snapped torsion spring keeps your door held by the other spring (most doors have two). A snapped extension spring can let your door fall suddenly. This is why a snapped spring requires immediate professional attention.

How to Know Which Type You Have
Walk into your garage and look up at the door opening. Do you see a tightly wound coil running horizontally across the top, above the door? That's torsion. Do you see springs running up and down the sides of the tracks? Those are extension springs.
Never touch or adjust springs yourself. They hold hundreds of pounds of tension and can cause serious injury if they snap while you're working on them. A professional technician has the right tools, safety equipment, and knowledge to handle them correctly.
Spring Replacement vs Repair
Once a spring breaks, it cannot be repaired. Springs are manufactured to exact specifications for your door's weight and size. A broken spring needs replacement, not patching.
The cost varies based on which type you have, door size, and whether both springs need replacement. If one torsion spring snaps, the other is usually near the end of its life too. Many homeowners replace both at once to avoid a second service call months later.

When to Call a Professional
Spring problems show themselves clearly. Your door won't open or closes too slowly. You hear a loud bang or snap. One side of the door sits lower than the other. The opener runs but the door doesn't move.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (about 3 to 5 cycles per day). Extension springs last 4 to 7 years. Lifespan depends on frequency of use, maintenance, and local humidity. Springs in humid climates like South Houston may wear faster.
Can I replace just one spring? Technically yes, but replacing both is smarter. If one torsion spring breaks, the other has usually lost tension too and will fail soon. Replacing both at once saves you a second service call and ensures balanced door operation.
What does a snapped spring sound like? A loud, sharp bang or crack, like a gunshot. If you hear this, don't try to open your door. Stop using it immediately and call a professional. A snapped spring can't support your door safely.
How much does spring replacement cost? Cost depends on spring type, door size, and whether you replace one or both. Torsion replacement runs higher than extension because they're more complex to install. Our detailed cost breakdown covers pricing ranges for South Houston homes.
Is it safe to use my garage door with a broken spring? No. A broken spring removes half the lifting force on your door. Using the opener risks damaging the motor and creates a safety hazard if the door falls. Call a professional before operating the door again.
