After 15 years turning wrenches on garage doors across Cotati and the North Bay, I can tell you straight: most homeowners don't understand garage door springs until one snaps. Then panic sets in. Springs are the hardest working part of your system, handling roughly 10,000 cycles before wearing out. Let's cut through the confusion about what they do, why they fail, and what you'll actually pay to fix them.
Your garage door weighs between 300 and 500 pounds. You can't lift that by hand, and your opener can't either. That's where springs come in. They counterbalance the door's weight so your opener uses just a fraction of its motor power to raise and lower it. Without springs, that motor would burn out in months.
There are two main types: torsion and extension springs. Torsion springs sit above the door on a metal shaft and twist as the door moves. Extension springs run along the sides of the door and stretch as it lowers. Most residential doors in Cotati use torsion springs because they're safer and last longer (typically 7 to 9 years with normal use). Extension springs wear out faster and can be hazardous if the cable breaks.
When a spring is working properly, you barely notice it. You press the button, the door glides up smoothly, and comes down just as gently. When a spring fails, everything changes immediately.
Metal fatigue is the main culprit. Springs expand and contract thousands of times. Over years, that repetition creates tiny cracks that eventually give way. Cold weather accelerates this process. Here in Cotati's wet winters, moisture can rust the shaft and weaken the spring faster. Heavy use, poor maintenance, and cheap garage door openers also shorten spring life.
A snapped spring usually announces itself loudly. You'll hear a bang or crack from the garage, and suddenly the door won't open, or it opens crooked and stops halfway. Some folks think the opener broke. It didn't. The spring did. If you notice the door is harder to open, moves slowly, or makes creaking sounds, that's a warning sign. Check our garage door maintenance guide for preventive steps you can take right now.
Don't try to open a door with a broken spring yourself. The door is now dead weight. You risk serious injury. Call a professional.

Here's where homeowners get sticker shock. A single torsion spring replacement typically runs $200 to $400 in labor and parts. If both springs need replacing (which is smart, since the second one will fail soon after), you're looking at $400 to $800 total. Extension springs cost less to replace but shouldn't be your first choice for safety reasons.
Several factors affect your final cost. The type of door (residential versus commercial), spring size, and whether you need new cables too all matter. If rust is involved or the shaft is damaged, repair gets more expensive. Our team provides a free estimate before any work starts, so you know exactly what you're paying for.

If you're facing a snapped spring and your door won't budge, that's an emergency. We offer same-day service for broken springs throughout Cotati and surrounding areas. The faster you get it fixed, the less risk of further damage to your opener or door panels. See our emergency garage door service page for details on availability.
You can't stop springs from aging, but you can slow it down. Lubricate your springs twice a year with a silicone-based spray. Keep the garage reasonably dry to prevent rust. Don't ignore warning signs like slow operation or unusual noises. Annual maintenance catches problems early and extends spring life by a year or more.
Regular tune-ups also catch misaligned doors and worn cables before they stress the springs further. A small investment in maintenance prevents a large bill down the road. Our full maintenance services include spring inspection and lubrication.
Spring replacement isn't something to put off. A broken spring leaves your door stuck and your family unable to access the garage. Get it handled today. Call us at 510-949-3486 or contact us online to book same-day service if needed.
How long do garage door springs typically last? Most residential torsion springs last 7 to 9 years under normal use, roughly 10,000 full cycles. Extension springs wear faster, usually 5 to 7 years. Cold, wet climates like Cotati can shorten lifespan due to rust and metal stress.
Can I replace a garage door spring myself? Not safely. Springs are under extreme tension and can cause serious injury or death if they slip or snap during removal. Always hire a licensed technician with proper tools and training for this job.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are safer, more durable, and last longer. Extension springs stretch along the sides and are cheaper but less reliable and more hazardous if cables fail.
How much does a garage door spring replacement cost? Single spring replacement typically costs $200 to $400. Both springs together run $400 to $800, depending on door size, spring type, and whether additional repairs are needed. Get a free estimate before committing.
Why did my spring break so suddenly? Metal fatigue from repeated expansion and contraction over years weakens springs until they snap. Cold weather, humidity, and rust speed this process. Regular lubrication and maintenance help, but replacement is inevitable eventually.
