If you've ever dealt with a stuck garage door that won't budge, a snapped spring is probably why. Most homeowners don't realize their garage door relies on one or two metal coils under extreme tension to lift a 300 to 500-pound door. When one fails, the entire system fails. Understanding the difference between torsion and extension springs helps you recognize trouble early and know what to expect when you need a repair.
Torsion springs and extension springs work on completely different principles, and the type you have determines how your door behaves and what goes wrong.
Torsion springs mount horizontally above your garage door opening, parallel to the header. They twist and store energy like a wound clock spring. As the door closes, the springs wind tighter. As it opens, they unwind and release that stored energy to help lift the weight. Most residential garage doors in Onalaska use torsion springs because they're safer, more durable, and last 7 to 9 years with proper maintenance.
Extension springs hang vertically on either side of the door track. They stretch when the door closes and contract when it opens, using that elastic rebound to assist the opener motor. Extension springs are cheaper upfront but wear faster and pose a greater safety risk if they snap. A broken extension spring can send sharp metal pieces flying or cause the door to drop suddenly.
Springs work in pairs on most doors. Even if only one breaks, both must be replaced together. Here's why: when one spring fails, the remaining spring carries double the load. It fails within days or weeks. Replacing them as a pair ensures balanced weight distribution and prevents premature failure of the remaining spring.
A snapped spring also means your garage door opener won't lift the door. The motor simply can't handle the full weight alone. Trying to force it puts stress on the opener and can cause additional damage. That's why a stuck door is often your first sign of spring trouble.
Listen for a loud bang or crack from above the door. That's the sound of a spring breaking under tension. After that noise, your door either won't open or opens very slowly and unevenly.
Look for visible gaps or separation where the spring attaches to the mounting hardware. A sagging door that's lower on one side than the other signals uneven spring tension. You might also notice your opener running but the door not moving, or the door slamming down faster than usual.
If you see any of these signs, don't attempt DIY repairs. Springs carry 10,000 pounds of stored tension. A slip or mistake can cause serious injury. Our team at Garage Door Spring Replacement in Onalaska: Signs, Costs, and Why You Shouldn covers exactly what happens during a professional replacement.

Scheduling matters, especially during spring and fall when we're busiest. The sooner you report the problem, the faster we get you back to normal operation.
Regular maintenance extends spring life significantly. Lubricate your springs every 6 months with a garage door-specific lubricant. Keep the tracks clean and aligned. Check the door's balance monthly by opening it halfway and releasing it. If it falls or rises on its own, springs are losing tension.
Our garage door maintenance tune-up guide includes spring care steps you can do yourself. However, never attempt to adjust spring tension without professional training.

How long do garage door springs last? Most torsion springs last 7 to 9 years with normal use. Frequency matters. A door opened 4 to 8 times daily will wear springs faster than a door opened 2 to 3 times daily. Extension springs wear out faster, typically 5 to 7 years.
Can I replace one spring instead of both? No. Paired springs must be replaced together. If one fails, the other is near the end of its life and will fail soon. Replacing only one causes uneven tension, door damage, and safety hazards.
What's the difference between a torsion and extension spring failure? Torsion spring failure usually results in a loud bang and a door that won't open. Extension spring failure is more dangerous. The spring can snap suddenly, sending metal shrapnel flying or causing the door to drop without warning.
How much does spring replacement cost in Onalaska? Expect $400 to $800 total for both springs and labor. Torsion springs cost more than extension springs but last longer and are safer. Get a free estimate by calling us at 13609002297.
