Garage Door Spring Types in Platteville: Torsion vs. Extension (Which Do You Have?)

2026-09-19 5 min read

Most homeowners don't think about their garage door until something breaks. Then they're staring at a door that won't budge and realizing they have no idea what a torsion spring is, let alone an extension spring. Here's what you need to know: your garage door relies on one of two spring types to lift and lower smoothly. Understanding which one you have could save you money, prevent injury, and help you communicate with a technician faster when things go wrong.

Two Spring Types: Torsion vs. Extension

Your garage door weighs 300 to 500 pounds. Without springs, that weight would crash down. Two mechanisms handle this load.

Torsion springs are mounted horizontally above your garage door opening, running along a metal rod. They twist (hence "torsion") to store and release energy as the door moves. Most modern residential doors in Platteville use torsion springs. They're safer, quieter, and last longer than their counterpart.

Extension springs hang vertically on both sides of your door, next to the tracks. They stretch and contract like a rubber band to counterbalance the door's weight. Older homes and lighter doors often use these. They wear faster and pose a higher safety risk if a cable snaps.

How do you know which you have? Look above your door opening. If you see a horizontal rod with a tightly wound spring barrel in the center, that's torsion. If you see two springs running up and down the sides along the tracks, those are extension springs.

Why This Matters When Springs Fail

When a spring snaps, your door becomes a dead weight. You can't open it manually without serious risk of injury. The force required to lift 400 pounds without spring assistance has crushed hands and caused permanent damage.

The spring type also affects repair cost and timing. Torsion springs are more expensive to replace but last 7 to 9 years with proper maintenance. Extension springs cost less upfront but often need replacement every 4 to 7 years. If you have extension springs and one breaks, the other is usually close behind because they wear at the same rate.

More importantly, extension springs are connected by cables. If a cable snaps, the spring can whip across your garage at dangerous speeds. We've seen this cause serious lacerations and eye injuries. Torsion springs, while still dangerous if mishandled, keep that stored energy contained around the rod.

What Happens When a Spring Snaps

A snapped spring usually announces itself with a loud bang or crack. Your door will either stop moving mid-cycle or drop suddenly. Some people notice the door is harder to open by hand even if the opener still works. That's a sign the remaining spring can't handle the load alone.

Never attempt to replace springs yourself. This isn't a DIY project like changing weather stripping. Springs hold thousands of pounds of force under tension. Without proper tools, knowledge, and safety equipment, you risk serious injury. Professional technicians use specialized equipment to safely release that tension before replacement.

If you suspect a snapped spring, stop using your door and schedule a free quote with a licensed technician. Continued use with a broken spring puts extra strain on your opener and tracks, turning a $300 spring replacement into a $1,200 opener replacement.

Maintenance Extends Spring Life

You can't prevent springs from eventually wearing out, but you can slow the process. Proper lubrication every 6 months keeps torsion springs functioning smoothly. Regular door balance checks catch issues before they become emergencies. High winds and temperature swings (common in Colorado) stress springs faster, so Platteville homeowners should inspect springs seasonally.

If you've never had your springs inspected, our seasonal maintenance checklist covers what you should be checking. A technician can also assess spring condition during a routine inspection and give you a cost estimate for replacement before failure happens.

Frequently Asked Questions

How long do garage door springs last in Platteville? Torsion springs typically last 7 to 9 years with regular maintenance. Extension springs usually last 4 to 7 years. Lifespan depends on door use frequency, climate, and lubrication habits. Colorado's temperature swings can accelerate wear.

Can I replace a garage door spring myself? No. Springs hold thousands of pounds of force under tension. DIY replacement risks serious injury, including crushed fingers, lacerations, and eye damage. Always hire a licensed professional with proper tools and training.

What's the cost difference between torsion and extension spring replacement? Torsion springs typically cost more to replace (usually $200 to $400 per spring) but last longer. Extension springs cost less upfront ($100 to $200 per spring) but wear faster and often need replacement sooner.

How do I know if my garage door spring is about to break? Signs include a door that's harder to open manually, slower closing speed, visible rust or corrosion on the spring, and loud creaking or groaning. If you notice these, have it inspected before complete failure occurs.

Is it safe to use my garage door if one spring is broken? No. Using the door with a snapped spring strains your opener and tracks, risking additional damage and potential injury. Stop using the door and call a technician for repair.
