Your garage door springs are the hardest working part of your system, and when one snaps, the door won't budge. Most homeowners in Petaluma don't know the difference between torsion and extension springs, which types fail first, or why a professional matters. Here's what you actually need to know to make the right call.
Springs do all the heavy lifting. A typical garage door weighs 300 to 400 pounds. Without springs, your opener would need to be powerful enough to lift that weight alone, which would burn out fast and cost a fortune. Springs counterbalance the door's weight, making it feel almost weightless when you open it manually or with an opener.
There are two main types: torsion springs and extension springs. Each works differently, fails differently, and costs differently to replace.
Torsion springs are wound coils mounted horizontally above your garage door. When you open the door, they twist and store energy, then release that energy to help lower the door smoothly. Most modern homes in Petaluma use torsion springs because they're more durable, safer, and last longer.
A quality torsion spring lasts 7 to 9 years with normal use. Some premium springs reach 10 years. When a torsion spring snaps, you'll hear a loud bang. The door becomes dead weight. You can't open it manually, and your opener won't budge it either.
The good news: torsion springs are predictable. When they fail, they fail completely, not gradually. This means fewer surprises on a Tuesday morning.

Extension springs run vertically along each side of your door. They stretch and contract as the door moves up and down. They're cheaper upfront but wear out faster, typically lasting 5 to 7 years.
Extension springs also have safety cables running through them. If a spring snaps, the cable catches it and prevents the spring from whipping across your garage. Without that cable, a snapped spring becomes a dangerous projectile. This is why extension springs require more maintenance and inspection.
Many older garages in Petaluma still have extension springs. If yours are original to your home and your door is over 10 years old, they're on borrowed time.
Springs fail from metal fatigue, not abuse. Every cycle, the metal weakens slightly. After thousands of open and close cycles, the material reaches its limit and snaps. This happens to every spring eventually. Age, temperature swings, humidity, and how often you use your garage all factor in.
Sonoma County's coastal weather doesn't help. Salt air and moisture accelerate corrosion on uncoated springs.
If your door won't open, a snapped spring is the likely culprit. Don't force it. Forcing a dead door can damage your opener and tracks.

We always recommend replacing both springs at the same time, even if only one snapped. The second one isn't far behind. Replacing them together saves labor and prevents a second failure in six months.

A snapped spring doesn't fix itself. The longer you wait, the more risk you take. A door stuck in the down position blocks your car. A door stuck open is a security risk. Cold mornings in Petaluma make the metal even more brittle.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with regular use. Extension springs last 5 to 7 years. Lifespan depends on door weight, cycle frequency, and climate. Coastal areas experience faster corrosion.
Can I replace a garage door spring myself? Springs are under extreme tension and extremely dangerous to work with. A snapped spring can cause serious injury. Always hire a licensed professional for spring replacement and repair work.
How much does a garage door spring replacement cost? Costs vary by spring type, door size, and whether you replace one or both. Single torsion spring replacement ranges from $200 to $400. Extension springs cost less, but we recommend replacing both springs to avoid second failures. Request a free estimate for your specific door.
What's the difference between torsion and extension springs? Torsion springs mount horizontally above the door and twist to store energy. Extension springs run vertically on each side and stretch. Torsion springs last longer, are safer, and handle heavier doors. Extension springs are cheaper but wear faster.
Why did my spring snap without warning? Springs fail from metal fatigue after thousands of cycles, not from sudden impact or misuse. The failure point is unpredictable, though older springs are more likely to fail. Regular inspection can catch signs of wear before complete failure.
