A broken garage door spring stops your door dead. It won't open, won't close, and you're stuck in your driveway. The spring has failed, and no amount of button pressing will fix it. This is not a DIY moment. Here's what you need to know right now.
Your garage door relies on either torsion springs (wound around a shaft above the door) or extension springs (running along the sides). Both types are under enormous tension. A single spring can support hundreds of pounds. When metal fatigues after years of opening and closing, it snaps.
Springs last roughly 7 to 9 years under normal use, depending on how often you open and close the door. Rust, lack of lubrication, or a sudden shock can accelerate failure. One day the door works fine. The next, you hear a loud bang and the door goes slack. That's the spring breaking.
The door itself isn't damaged. The opener isn't broken. But without a functioning spring, the door's weight becomes dead load. Your opener can't lift it safely, and the door won't balance properly. Forcing it risks damage to the opener motor, cables, or worse, injury to you.
Don't try to manually lift the door. A 300 to 400-pound garage door with a broken spring is a crushing hazard. Don't attempt to replace the spring yourself. Torsion springs especially carry residual tension even when "deactivated." They can snap back violently and cause serious injury.
Don't ignore it and keep using the door. A broken spring puts extra strain on your opener and can cause secondary failures. If you have a snapped spring and missed the warning signs, stop operating the door immediately.

First, stop using the door. Park outside if you must. Second, contact a licensed technician. Spring replacement requires specialized tools, knowledge of proper tension, and safety protocols that only trained professionals should handle.
When you call for an estimate, be ready to describe what happened. Did you hear a loud noise? Is the door stuck open or closed? Does the door hang unevenly on one side? These details help us diagnose whether it's a torsion spring, extension spring, or both that need replacement.
Most spring jobs can be completed the same day. We'll inspect the entire system, check cable condition, and verify the opener is functioning properly. The cost varies based on spring type and door size. Understanding repair versus replacement costs helps you make an informed decision.
A technician will balance your door correctly after spring replacement. Improper tension causes the door to drift open or slam shut. It stresses the opener and creates a safety hazard. We also check for signs of rust or wear on other components while we're there.
If your springs are nearing the end of their lifespan, we may recommend replacing both at once. Even if only one is broken, the other is probably close behind. Replacing both springs simultaneously prevents a second failure weeks later and ensures balanced operation.

After replacement, maintenance matters. A quick spray of garage door lubricant on the springs and tracks every six months extends spring life and catches small issues before they become emergencies. Check out our maintenance guide for Novato homeowners to keep your system running smoothly.
If your door has never had a professional inspection, now's the time. A broken spring is disruptive, but it's also a wake-up call that your system needs attention. Browse our full service options to see what else may need attention.

Can I open my garage door if the spring is broken? No. Without a functioning spring, the door's weight becomes unmanageable. Attempting to open it risks injury and damage to the opener. Wait for professional repair.
How much does spring replacement cost? Cost depends on spring type (torsion or extension), door size, and whether one or both springs need replacement. Call for a free estimate to get an accurate quote for your situation.
How long does spring replacement take? Most jobs take one to two hours. We often complete work the same day you call, depending on schedule and part availability.
Why did my spring break suddenly? Springs weaken over time through repeated use. After 7 to 9 years, metal fatigue makes them prone to sudden failure. Rust, poor maintenance, or extreme temperature swings accelerate breakdown.
Should I replace both springs even if only one is broken? Yes, if both springs are similar age. When one fails, the other is likely near failure too. Replacing both at once prevents a second breakdown and ensures balanced door operation.
