If your garage door suddenly stopped moving or won't open at all, a broken spring is likely the culprit. Springs are the hardest working part of your door, and when they snap, nothing moves. This guide explains what causes spring failure, the real cost of repair, and why DIY fixes belong in the "don't do it" category.
Your garage door weighs 300 to 500 pounds. Without springs, your opener motor would burn out in weeks trying to lift that load. Springs do the heavy lifting. They store energy as the door closes, then release it to help the door open smoothly.
There are two main types: torsion springs and extension springs. Torsion springs wind up like a clock and sit above the door on a metal rod. Extension springs stretch and contract, running parallel to the horizontal tracks on each side. Most residential doors in Lemon Grove use torsion springs because they're safer and last longer.
Springs last 7 to 9 years under normal use. That's roughly 10,000 to 15,000 cycles (open and close). A few factors speed up that timeline.
Rust and corrosion eat away at spring metal, especially in coastal areas near San Diego where salt air is constant. Springs need lubrication to move freely. Without it, friction creates stress that leads to early failure.
Temperature swings matter too. Lemon Grove's mild winters and warm summers still create expansion and contraction. Metal fatigues. One day the door works fine; the next, you hear a loud bang and everything stops.
Poor maintenance accelerates failure. Check our garage door maintenance guide for the San Diego climate to understand how local weather impacts your springs specifically.
A snapped spring repair typically runs $200 to $400 for a single torsion spring, including labor and the part itself. If both springs fail at once (common), budget $400 to $600. For a detailed cost breakdown across different repair scenarios, see our guide to garage door spring replacement costs.

Why not DIY? Spring tension is lethal. A snapped spring releases energy equivalent to a loaded crossbow. People have been killed trying to replace springs at home. The risk isn't worth saving $100.
Listen for a loud metallic pop or crack. That's a spring snapping under load. Afterward, the door either won't open or opens partway then drops. The opener may hum but the door won't budge.
Another sign: the door feels heavier than normal. Your opener compensates for a weakening spring, burning more power. If you notice the door sagging or moving unevenly, springs are stressed.
Don't wait for a complete failure. A near me search for "garage door repair" shouldn't be your first option. Call a professional before the door gets stuck with your car inside.
Stop using the door. Every cycle stresses the remaining springs further. If you have a snapped spring, the door is likely stuck. Forcing it risks damage to the tracks, rollers, or opener.
Call Garage Door Lemon Grove or another trusted local technician for an estimate. We offer same day service and can diagnose the problem over the phone. Most repairs take under an hour.
While you wait, don't try to pry the door open manually. Don't use the opener if you hear grinding or unusual noises. The door will stay down safely until we arrive.
Apply a silicone based lubricant to springs every six months. Clean debris from the tracks and hinges. Have your door inspected annually to catch small problems before they become expensive ones.
If your door is over 10 years old and still on the original springs, replacement is coming. Budget for it now rather than facing an emergency repair bill later. We can schedule a free quote and discuss your options at any time.
Springs don't fail without warning. Small signs appear first: noise, resistance, uneven opening. Address those early and you'll avoid getting stuck at the worst possible moment. Lemon Grove homeowners who stay on top of maintenance spend less and deal with fewer emergencies.
The cost of prevention is always less than the cost of emergency repair. Call 619-453-0069 today to book a spring inspection or get a same day repair estimate.
How long do garage door springs last? Most residential torsion springs last 7 to 9 years under normal use, which equals roughly 10,000 to 15,000 open/close cycles. Extension springs typically last 5 to 7 years. Lifespan varies based on climate, maintenance, and how often you use the door.
Can I replace just one spring if both are old? Technically yes, but it's not smart. If one spring has reached the end of its life, the other is close behind. Replacing both at once costs more upfront but saves money on a second service call within months.
What happens if a spring breaks while the door is open? The door may drop suddenly if the spring snaps under load. If it's open, gravity pulls it down fast. This is dangerous and can damage the door, tracks, or anything beneath it. Never leave a door open with failing springs.
Is spring repair expensive compared to replacement? Repairs aren't really an option. Springs can't be welded or patched. Once broken, replacement is the only fix. A single torsion spring replacement costs $200 to $400, while both springs run $400 to $600 including labor and parts.
Why shouldn't I replace springs myself? Spring tension can cause serious injury or death. A loaded torsion spring has enough energy to crush bones or cause fatal wounds if it releases unexpectedly. Professional technicians have the tools and training to handle this safely. Always hire a licensed repair service.
