How Garage Door Springs Work in Union: A Technician's Breakdown
2026-07-04 7 min read
Here's what most homeowners don't realize about garage door springs: they're doing nearly all the work. Your opener gets the credit, but those coiled metal bars are what actually lift a 300 to 400 pound door. After 15 years pulling springs on driveways across Union and the greater Tacoma area, I've learned that understanding how they function saves you money and keeps your family safe.
Two Types of Springs: Torsion vs. Extension
Your garage door uses one of two spring systems, and knowing which one you have matters.
Torsion springs sit above the door on a metal rod. They twist and unwind, storing rotational energy. When you open the door, they release that tension gradually. Most modern residential doors in Union use torsion springs because they're more controlled and safer.
Extension springs hang on both sides of the door track. They stretch and contract like rubber bands. They're cheaper upfront but wear faster and can be riskier if one snaps because the door loses half its counterbalance suddenly.
Torsion springs typically last 7 to 9 years with normal use. Extension springs might hit 5 to 7 years. That lifespan depends on how often you open and close the door. A family that uses the garage three times daily will see springs fail sooner than someone who uses it once a day.

Why Springs Fail: The Physics Behind the Break
A snapped spring isn't random. It's metal fatigue. Every cycle, the spring stretches or twists a little bit. Microscopic cracks form inside the coil. After thousands of cycles, those cracks grow until the metal gives.
Weather accelerates this. Cold temperatures make metal brittle. In Union winters, we see a spike in spring failures from November through February. Rust also weakens springs from the inside out. If your garage isn't sealed well, moisture creeps in and corrodes the metal.
One thing I tell customers: don't wait for a complete break. Check the warning signs that tell you a replacement is coming. A door that's getting harder to open or closing too fast is telling you the springs are losing strength.
The Cost Reality
Spring replacement isn't cheap, but it's cheaper than ignoring the problem. A snapped spring leaves you with a stuck door and no way to open it safely. Trying to force it can damage the opener or the tracks.
A single torsion spring replacement typically runs $200 to $400 in labor and parts, depending on the spring size and type. Extension springs are usually $150 to $300. If both springs have failed (which happens), you're looking at more. For exact pricing on your specific door, get a same-day estimate from Garage Door Union.
Many people ask if they should replace just one spring when both are the same age. My answer: both springs wear together. Replacing one leaves the other likely to fail within months. The math doesn't work in your favor. Our pricing guide breaks down what you should expect to spend.
What Happens When a Spring Snaps
A snapped torsion spring makes a loud bang. The door won't open. Your opener will hum and strain but won't budge the door because it's lost counterbalance.
A snapped extension spring is less dramatic but equally stuck. The door might move partway then jam. Never try to manually force a garage door with a broken spring. You risk crushing your fingers or damaging the entire system.
Call a professional same-day if this happens. We can diagnose the issue, assess whether the opener is damaged, and replace the spring safely. This is not a DIY job. Springs are under extreme tension and can cause serious injury if you don't know what you're doing.
Maintenance Keeps Springs Healthy
You can't prevent springs from wearing out, but you can slow the process. Keep the garage door tracks clean and lubricated. A garage that stays reasonably dry lasts longer than one that's damp. If you notice rust forming on the spring or rod, have it inspected.
Proper opener maintenance also reduces strain on springs. A well-tuned opener doesn't force the springs to work harder than they should.
Next Steps
If your door is getting older or you've noticed signs of spring wear, don't wait for a failure. A professional inspection takes 15 minutes and costs nothing. We'll tell you exactly how much life is left in your springs and what the replacement will run.

Frequently Asked Questions
How do I know if my garage door spring is broken? The door won't open, or it opens very slowly and unevenly. You might hear a loud bang or snap. The door may hang at an angle. Never force it. Call a technician right away.
Can I replace a garage door spring myself? Springs carry extreme tension and can cause serious injury or death if mishandled. This is a job for licensed professionals only. DIY attempts often result in hospital visits.
How long do garage door springs last? Torsion springs typically last 7 to 9 years. Extension springs last 5 to 7 years. Lifespan depends on use frequency, weather, and maintenance. Dry garages see longer spring life than damp ones.
What's the difference between a torsion and extension spring? Torsion springs twist above the door and are safer, more durable, and common in modern homes. Extension springs stretch on the sides, cost less initially, but wear faster and can be riskier.
Should I replace both springs if only one broke? Yes. Springs wear together over time. Replacing one leaves the other likely to fail within months. Replacing both at once is more cost-effective long-term.
