Your garage door won't budge. You hear a loud bang from above, and suddenly the door feels impossibly heavy. You've just experienced a snapped spring, one of the most common (and most dangerous) garage door failures homeowners face. The good news: you have safe options. The bad news: this isn't a DIY repair, and waiting makes it worse.
A snapped spring means one of two things broke: either a torsion spring above your door or an extension spring on the sides. Both types carry enormous tension, storing enough energy to lift a vehicle. When a spring fails, that stored energy releases violently. I've seen springs snap through drywall, ricochet across garages, and nearly hit people standing nearby. This is why I always tell Monrovia residents: do not attempt a spring repair yourself.
The spring typically lasts 7 to 9 years before metal fatigue causes failure. If you haven't replaced yours in that timeframe, you're living on borrowed time. Your garage door opener cannot lift the door without working springs, so the motor will either stall or burn out trying.
Stop trying to open the door. Do not use the opener. If the door is stuck open, leave it open. A snapped spring means your door has no counterbalance and could crash down unexpectedly, crushing anything (or anyone) underneath.
If you need to access your garage, use a side door. If the door is partially open and blocking a car or emergency exit, call a professional immediately. Same-day service exists for exactly this reason.
Do not attempt to manually lift the door or prop it up with boards or jacks. The unbalanced weight will shift, and you risk serious injury.

Both spring types work differently but fail for the same reason: metal fatigue. Every time your door opens and closes, the spring cycles through stress. After 10,000 to 15,000 cycles (roughly 7 to 9 years for an average household), the metal weakens and snaps.
Rust accelerates failure, especially in coastal areas like Monrovia where salt air corrodes metal faster. Lack of lubrication, extreme temperature swings, and manufacturing defects also shorten spring life.
If one spring breaks, the other is likely close behind. This is why professionals recommend replacing both springs at the same time, even if only one snapped. You'll avoid a second emergency repair in a few weeks.
Springs operate under 200 to 500 pounds of tension. A wrench slip or improper tool placement can cause serious injury or death. I've seen too many DIY attempts end in emergency room visits.
A licensed technician has the right tools, safety equipment, and knowledge to disconnect the tension safely, remove the broken spring, and install a replacement correctly. They'll also inspect your door, tracks, rollers, and opener to catch other problems before they strand you again.

The cost depends on your spring type, door size, and whether one or both springs need replacement. A torsion spring replacement typically costs more than an extension spring replacement because it's more complex and dangerous to install.
Most homeowners pay $150 to $400 per spring, including labor. If both springs need replacement, budget $300 to $800 total. Emergency or same-day service may add a rush fee.

Have your springs inspected annually as part of routine garage door maintenance. A technician can spot rust, listen for creaking, and measure spring tension to predict failure before it happens.
Lubricate your springs twice a year with a silicone-based garage door lubricant. This reduces friction and extends lifespan slightly. Never use WD-40 on springs; it attracts dust and actually accelerates wear.
If your door is old, consider proactive replacement. One $500 repair now beats a $1,200 emergency call plus a burned-out opener later.
Call a professional immediately. Most shops in the Monrovia area offer same-day estimates and repairs for snapped springs. When you call, describe what happened: heard a bang, door won't open, etc. This helps the technician arrive prepared.
Expect the repair to take 1 to 2 hours. You'll be without garage door access during that time, so plan accordingly if you need your car.

A snapped spring feels like a disaster, but it's fixable. The key is acting fast and trusting a professional. Your safety depends on it.
Can I drive my car out if the door is stuck halfway down? No. The unbalanced door could fall or shift unexpectedly. Wait for a professional to assess and safely raise or lower it using manual tools.
How long does spring replacement take? Typically 1 to 2 hours, depending on spring type and whether one or both springs need replacement. Same-day service is usually available in Monrovia.
Is a snapped spring covered by warranty? Most springs carry a manufacturer warranty of 1 to 5 years from purchase. Springs that fail from normal wear or rust are usually not covered. Check your original paperwork.
What's the difference between torsion and extension springs? Torsion springs sit above the door and twist to lift it. Extension springs run along the sides and stretch. Torsion springs are more durable but costlier to replace. Learn more about spring types.
Can I replace just one spring? Technically yes, but not recommended. If one spring failed, the other is near end of life. Replacing both now prevents an emergency call in weeks.
