Garage Door Springs in Edmonds: Torsion vs. Extension Explained
2026-08-07 7 min read
Your garage door springs are under roughly 10,000 pounds of tension. When one snaps, the door won't open, and you're stuck. Here's what you need to know about garage door springs in Edmonds: torsion springs are the industry standard, extension springs are older, and both fail eventually. This guide cuts through the confusion so you can make an informed repair decision.
What Are Garage Door Springs, and Why Do They Matter?
Springs do the heavy lifting. They counterbalance your door's weight so the opener motor doesn't burn out and the door moves smoothly up and down. Without them, a standard garage door weighs 300 to 400 pounds. Your opener would fail in months.
Most modern doors in the Edmonds area use torsion springs. These sit above the door on a metal rod and twist to store energy. Older homes sometimes have extension springs that stretch and contract on either side of the door tracks. Both systems work, but they behave differently when they wear out.
Springs typically last 7 to 9 years with normal use. That's roughly 10,000 to 15,000 cycles (one cycle equals opening and closing). If your door gets heavy use, springs wear faster. Climate matters too. The Pacific Northwest's moisture and temperature swings can speed corrosion.
Torsion Springs: The Right Choice for Most Homes
Torsion springs are the gold standard. They're safer, last longer, and distribute wear more evenly. When a torsion spring snaps, the door usually stays balanced and doesn't crash down suddenly.
Here's how they work: the spring wraps around a shaft above the door. As the door closes, the spring winds tighter, storing energy. When you open the door, that stored energy releases, helping lift the weight. It's mechanical engineering at its finest.
The downside? Torsion springs cost more to replace than extension springs. You're also looking at specialized labor. These springs are under extreme tension and require proper tools and training to replace safely. If you've noticed your door getting harder to open or hanging unevenly, a snapped spring is likely the culprit.

Extension Springs: Older, Riskier, Still Around
Extension springs are less common in newer construction but still exist in older Edmonds homes. They stretch above the door tracks, one on each side. When the door closes, they extend. When it opens, they contract.
Extension springs have safety cables running through them. This is critical: if the spring snaps, the cable catches it and prevents it from flying across your garage. Without the cable, a snapped extension spring becomes a dangerous projectile.
If your door uses extension springs and one breaks, replace both at the same time. They wear at similar rates. Replacing only one creates imbalance and speeds up failure of the remaining spring.

How to Know Your Spring Is Failing
A snapped spring is obvious: the door won't open, even though the opener runs. You'll hear the motor working, but nothing happens. Sometimes you'll hear a loud bang when the spring fails. That sound is the metal rod whipping or the spring separating under load.
Before complete failure, watch for warning signs. If your door closes faster than it opens, or if it feels heavier to operate, a spring is weakening. If the door hangs crooked or pulls to one side, one spring is likely already gone or failing.

Spring Replacement Cost in Edmonds
A single torsion spring replacement typically runs $150 to $300 for the part, plus $200 to $400 in labor. Extension springs are cheaper parts (maybe $50 to $150 each) but often need the same labor time. If you need both springs replaced, expect $400 to $800 total depending on the system.
The cost includes the spring itself, installation, testing, and balance adjustment. Cheap shops sometimes rush the balance check. We take time to ensure the door opens and closes smoothly without binding or favoring one side.

Why DIY Spring Replacement Is a Bad Idea
Springs are dangerous. The tension in a torsion spring can snap a finger or hand. Extension springs can unwind violently and strike your face. People have died attempting spring replacement at home.
This isn't arrogance. It's respect for the tool. Professional technicians carry liability insurance, use safety cables and clamping tools, and know how to manage the tension safely. It costs less to have it done right than to visit an emergency room.

What to Do Right Now
If your springs are failing or you suspect they're near the end of their life, don't wait for a complete failure. A broken spring strands your car and disrupts your routine. It also puts stress on the opener and door panels.

Frequently Asked Questions
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years under normal residential use, translating to roughly 10,000 to 15,000 open-close cycles. Frequency of use, climate, and maintenance affect lifespan.
Can I replace just one spring? For extension springs, always replace both at once because they wear together. For torsion springs, it's tempting to replace only the broken one, but the other is likely near failure. Replacing both ensures balanced operation and longer overall life.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are safer when they fail. Extension springs stretch on either side and require safety cables to catch them if they snap. Torsion springs last longer and are more common in modern doors.
How much does a spring replacement cost near me? In Edmonds, expect $300 to $800 total depending on whether you need one or both springs replaced and your door's weight. Torsion springs cost more than extension springs, but labor is similar.
Is a garage door with a broken spring dangerous? Yes. A broken spring leaves the door unsupported, heavy, and prone to crashing. The opener also works harder and may fail. Don't attempt to operate the door yourself, and call a professional for same-day repair.
