A snapped garage door spring won't let your door open, and worse, it's a serious injury risk. Springs carry 400 pounds of tension per side. When one breaks, the other can't support the weight alone. Don't attempt a DIY fix.call a professional immediately for safe, reliable repair.
Garage door springs fail for predictable reasons, and most are preventable with regular maintenance.
Metal fatigue is the leading culprit. Torsion springs (the most common type in residential garages) cycle thousands of times over their 7 to 9 year lifespan. Each cycle weakens the metal slightly. Eventually, the spring reaches its breaking point. One morning, you press the opener button and hear a loud bang. That's the spring letting go.
Extension springs, mounted above the horizontal tracks on either side, fail the same way but less dramatically. You might notice the door won't open fully or feels heavier than usual before it snaps completely.
Rust and corrosion accelerate failure. If you live in a coastal area like nearby Marin County, salt air eats through metal fast. Humidity in Corte Madera garages creates the same problem. A spring that should last nine years might give out in five if it's exposed to moisture and never serviced.
Poor maintenance speeds the timeline. Springs need lubrication annually. Dust, grime, and lack of oil cause friction that weakens the coil. When you add temperature swings (Corte Madera sees 50-degree swings between seasons), metal expands and contracts, creating micro-fractures.
This isn't just an inconvenience. A snapped spring creates immediate hazards.
The door becomes a deadweight. If it's partially open when the spring breaks, it can slam down with force that crushes fingers, hands, or anything underneath. I've seen homeowners reach under a stuck door thinking they can nudge it. They can't. The door won't budge without that spring's counterbalance.
The opener motor can burn out trying to lift a door with no spring support. This compounds your repair cost. You might replace the spring only to discover the opener is now damaged too. That's why you should read about what drives your garage door repair bill before calling for help.
A broken spring also disables the auto-reverse safety feature on most modern openers. If the door is stuck and you're not home, someone could be injured if the door moves unexpectedly. This is why understanding auto-reverse safety matters for your family's protection.

The cost depends on spring type, door weight, and whether one or both springs need replacement.
A single torsion spring replacement typically runs $200 to $400, including labor. Extension springs cost less, around $150 to $250. But if both springs have the same age and stress level, replacing only one means the second will fail soon after. Many pros recommend replacing both at once for safety and longevity.
Labor time matters. A trained technician can swap a spring in 1 to 2 hours. However, diagnosis and setup take time too. That's why getting an accurate estimate upfront prevents sticker shock. We offer free estimates and can often schedule same-day repairs if you call before noon.
If your door is stuck and you need it open urgently, spring replacement is non-negotiable. You can't bypass a broken spring. You can't operate the door manually safely. Same-day service is available in Corte Madera and surrounding Marin neighborhoods.

You can't stop springs from aging, but you can slow the process.
Schedule annual maintenance. A quick inspection catches rust, loose hardware, and worn coils before they become emergencies. Lubrication is cheap insurance. A light spray of garage door lubricant on both springs and hinges costs under $20 and adds years to component life.
Monitor your door's behavior. If it's closing faster than usual, hesitating mid-cycle, or sounds different, get it inspected. Small changes signal that a spring is weakening. Catching this early means you choose your repair timing instead of having the spring choose for you.
Temperature matters in Corte Madera. Winter cold stiffens springs slightly, making them work harder. If you notice sluggish performance in December or January, don't wait until spring breaks. Have a technician assess the situation now.
Don't wait. A snapped spring needs professional repair within hours, not days.

How long do garage door springs typically last? Most torsion springs last 7 to 9 years with regular use and maintenance. Extension springs have similar lifespans. Lifespan shortens significantly in humid or coastal environments due to rust and corrosion. Annual lubrication and inspection extend the timeline.
Can I open my garage door if the spring is broken? No. A snapped spring removes the counterbalance that makes the door light enough to lift. The door becomes a 400-pound dead weight. Do not attempt to open it manually. Call a technician immediately for safe repair and replacement.
What's the difference between torsion and extension springs? Torsion springs wind around a rod above the door and store energy by twisting. Extension springs stretch along the tracks on either side. Torsion springs are more durable and safer but cost slightly more to replace. Both require professional service.
Is spring replacement covered by homeowners insurance? Most standard homeowners policies don't cover spring replacement because it's considered maintenance and wear. Check your specific policy. Some extended plans or add-ons may apply. Our team can discuss your situation when you call for an estimate.
Why should both springs be replaced at the same time? If springs are the same age, they've endured the same stress and cycles. Replacing only one means the other will fail soon after. Dual replacement prevents a second emergency call and saves money long-term by balancing wear evenly.
