Serving Schertz, we see this confusion all the time: homeowners aren't sure whether their garage door uses torsion or extension springs. The answer matters because the two types work differently, fail differently, and cost differently to replace. If your door is stuck, loud, or showing signs of wear, knowing which spring type you have is the first step toward an honest estimate and a safe repair.
Torsion springs sit horizontally above your garage door opening, mounted on a steel shaft. When the door opens, these springs twist and unwind, storing and releasing energy in a controlled spiral motion. Most modern residential garage doors in Schertz use torsion springs because they're durable, precise, and safer than extension springs.
A typical torsion spring lasts between 7 and 9 years under normal use. That lifespan depends on cycle count (how many times the door opens and closes) and maintenance. Springs are rated by cycles, usually ranging from 10,000 to 25,000 cycles per spring. If your door opens and closes eight times daily, you're looking at roughly 3,000 cycles per year.
Torsion springs handle the door's full weight directly, so they bear significant stress. When one snaps, the door typically won't move at all. The good news is that a snapped spring rarely damages other components. The bad news is you'll need professional help, and attempting a DIY repair is genuinely dangerous due to the tension stored in the shaft.
Extension springs run vertically along each side of the door frame. Instead of twisting, they stretch and contract as the door moves up and down. They're common on older homes and lighter residential doors, and they're less expensive upfront than torsion springs.
The springs pull and release repeatedly, and corrosion can accelerate failure. When an extension spring snaps, the door may still move slightly, but you'll feel a dramatic loss of balance and hear a loud bang.
Extension springs come with safety cables running through their centers. These cables are designed to catch a broken spring and prevent it from whipping across your garage. It's a critical safety feature that torsion springs don't need because of how they're enclosed.

Look above your garage door opening from inside the garage. If you see a horizontal metal shaft with springs wound around it, you have torsion springs. If you see springs running vertically down both sides of the frame, you have extension springs.
Don't touch either type. Even if the door is stuck, springs under tension can cause serious injury. This is one of those moments where calling a professional isn't just smart, it's essential.
Torsion spring replacement typically costs more than extension spring replacement because of the precision required during installation and the shaft work involved. However, torsion springs tend to be more reliable and require less frequent replacement over time.

Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause severe injury or death if mishandled. Always hire a licensed professional. DIY spring replacement voids most manufacturer warranties and creates liability.
How long do garage door springs last? Both torsion and extension springs typically last 7 to 9 years with normal use. Lifespan depends on cycle count, climate, and maintenance. Our area's heat and humidity can shorten that window.
What's the difference in cost between torsion and extension springs? Torsion springs generally cost more to replace due to installation complexity and shaft work. Extension springs are cheaper upfront but may require replacement more frequently in humid climates.
Is it safe to open my garage door if a spring is broken? No. A broken spring removes the counterbalance system. The door becomes extremely heavy and dangerous to operate manually or with an opener. Stop using the door and call a professional.
Why did my spring snap without warning? Springs wear gradually over thousands of cycles. Rust, lack of lubrication, extreme temperature swings, and age all accelerate failure. Regular maintenance can extend lifespan but won't prevent eventual replacement.
