Most homeowners in Mukilteo don't think about their garage door until something breaks. Then that door won't open, and you realize the whole system hangs on two metal coils you've never seen. Those are your springs, and when they snap, the door becomes a thousand-pound paperweight. After 15 years turning wrenches, I can tell you: spring failure is the single most common call we take.
Your garage door weighs 300 to 500 pounds. It shouldn't take Superman to lift it. That's why springs exist. They counterbalance the weight so your opener only has to manage a few pounds of actual resistance. Without them, your opener can't do its job, and you can't open the door by hand either.
Two main types serve Mukilteo homes: torsion springs and extension springs. Torsion springs sit above the door on a horizontal rod and twist to store and release energy. Extension springs run along the sides of the door and stretch. Both work, but torsion springs last longer (7 to 9 years on average) and fail more predictably. Extension springs wear faster and can snap without warning.
Springs don't last forever. Metal fatigues. Every time your door cycles up and down, the spring loses a tiny bit of strength. After thousands of cycles, something gives. Temperature swings in the Puget Sound region speed things up. Rust forms. Lack of lubrication accelerates wear.
You'll recognize a snapped spring instantly. The door won't budge. You'll hear a loud bang or crack when it happens, usually from the garage. If you see the door sitting crooked or one side lower than the other, a spring has likely failed. Never try to open a door with a broken spring. Your opener will strain and fail. Worse, the door could drop on a car, pet, or person.

A single spring replacement runs $150 to $300 on labor, plus $50 to $150 for the spring itself. If both springs fail (which happens), expect $300 to $600 total for parts and labor. It sounds steep until you realize a new opener costs $400 to $800, and a damaged door costs $1,500 to $4,000 to replace.
The real cost depends on your spring type, door size, and whether one or both springs need replacement. We always recommend replacing both at the same time. Why? If one spring has failed, the other is likely near the end of its life. Replacing one now and the second in six months means two service calls instead of one. It's smarter economically.

I get it. YouTube makes everything look easy. Spring replacement videos are all over the internet. Don't do it yourself. I've treated injuries from spring-related accidents that would change your mind fast. A wound spring holds tremendous energy. If something slips, it can snap a finger, crack ribs, or worse.
Springs are tensioned with specialized tools. Getting the tension wrong creates a door that won't balance, wears your opener prematurely, and creates a safety hazard. Professionals carry insurance. We guarantee our work. If something goes wrong, we fix it at no charge.

If your springs are still working but your door is getting older, now's the time to plan ahead. Springs last 7 to 9 years. Replacing them before they snap keeps your door safe and your opener running smoothly.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use. Extension springs often fail sooner, around 5 to 7 years. Frequency of use, lubrication, and local weather all affect lifespan.
Can I open my door if a spring is broken? No. Never attempt to open a door with a broken spring. You risk injuring yourself and damaging the opener. Call a professional immediately.
Is spring replacement covered by homeowners insurance? Most policies don't cover spring failure because it's considered normal wear and tear. Check your specific policy, but expect to pay out of pocket.
Why do both springs need replacement at the same time? If one spring has failed, the other is near the end of its life. Replacing both avoids a second service call in months and ensures balanced door operation.
What's the difference between torsion and extension springs? Torsion springs twist above the door and last longer. Extension springs stretch along the sides and wear faster. Torsion is more durable and safer overall.
