Garage Door Springs in Seattle: Torsion vs. Extension Explained

2026-07-06 7 min read A2Z Garage Doors

Your garage door springs are the hardest working part of your system. They counterbalance a door that weighs 300 to 500 pounds, lifting and lowering it thousands of times over their lifespan. When one snaps, your door becomes a safety hazard and a headache. Understanding the difference between torsion and extension springs helps you know what you're dealing with and why professional repair matters.

What Type of Spring Does Your Door Have?

Most residential garage doors in Seattle use one of two spring designs: torsion or extension. See our guide on garage door cost & pricing in seattle: hidden factors that change your quote.

Torsion springs wind around a horizontal shaft above your door opening. They store energy by twisting, then release it smoothly as your door moves. These are the preferred choice for modern installations because they last longer (7 to 9 years on average) and distribute force more evenly.

Extension springs run along the sides of your door frame and stretch to create lift. They're common on older homes and some budget installations. While cheaper upfront, they wear faster and pose greater safety risks when they fail because the door can drop suddenly.

You can identify which you have by looking above your door. Torsion springs sit centered on a rod. Extension springs hang vertically on each side. If you're unsure, don't poke around near them. A snapped spring under tension can cause serious injury.

Why Garage Door Springs Fail

Springs fail because of metal fatigue. Every cycle (up and down) weakens the steel slightly. After 10,000 to 20,000 cycles, the metal reaches its breaking point. In a typical household, that's 7 to 9 years of use.

Several factors speed up failure. Seattle's moisture and temperature swings corrode the metal from inside out. Lack of lubrication increases friction and wear. Improper tension during installation puts uneven stress on the coils. A door that's harder to open than it should be often signals a weakening spring.

When a spring snaps, you'll hear a loud bang. Your door won't open or close smoothly. You might notice the door tilting to one side or stopping mid-travel. This is the moment to call a professional, not the time to troubleshoot on your own.

The Cost Question

Spring replacement cost depends on the type and your door's specifications. Torsion springs typically run $150 to $350 per spring, plus labor. Extension springs are cheaper at $100 to $200 each, but you usually need two. Labor adds $150 to $300 to the total.

A snapped spring is also a good time to evaluate the health of your entire system. We recommend checking the opener, cables, and rollers while we're already working on your door. Small preventive replacements now avoid bigger problems later.

What Happens During Professional Spring Replacement

A technician will secure your door so it doesn't fall. They'll release tension on the old spring carefully using specialized tools. Then they'll install a new spring matched to your door's weight and balance it so your opener doesn't work too hard.

This process takes 1 to 2 hours. It's not DIY work. Even experienced homeowners risk serious injury attempting spring replacement. The tension in these springs is equivalent to a small car's weight pressing down on your garage floor.

After replacement, your door should open and close with light finger pressure. If it feels stiff or unbalanced, let your technician know immediately. Proper balance extends your new spring's life and protects your opener from strain.

Prevention and Maintenance

You can't stop springs from aging, but you can slow it down. Keep your springs lubricated with a light silicone spray twice a year. Avoid forcing your door open or closed. Test your door's balance monthly by opening it halfway and releasing it. A balanced door stays put.

Regular garage door maintenance catches problems early. A technician can spot a spring weakening before it snaps, saving you the emergency call.

Frequently Asked Questions

How do I know if my spring is about to snap? Listen for creaking sounds during operation. Watch for the door moving slower than usual or becoming harder to open. A single spring that's weakening often causes the door to tilt slightly to one side. These are your warning signs.

Can I replace just one spring if both are the same age? We recommend replacing both torsion springs at the same time. They age together, and replacing one leaves the other to fail within months. With extension springs, replacing just one can create balance problems.

Is a snapped spring an emergency? Yes. A broken spring makes your door unsafe and difficult to open. It also strains your opener. Contact a professional immediately rather than forcing the door or trying to lift it manually.

How often should springs be replaced? Most residential springs last 7 to 9 years with normal use. Heavy use or harsh weather in Seattle can shorten that to 5 to 7 years. Have your springs inspected annually to catch wear early.

Why shouldn't I replace springs myself? The tension stored in garage door springs equals hundreds of pounds of force. Releasing it improperly causes serious injury or death. Special tools and training are required. Professional installation is safer and more reliable.
