If your garage door won't budge and you hear a loud bang, you probably have a snapped spring. After 15 years on service calls, I've seen this happen in driveways across National City and the South Bay more times than I can count. A broken garage door spring is one of those problems you can't ignore, and it demands professional help. Here's what you need to know about the issue, the cost, and how to get back on the road fast.
Springs fail for straightforward reasons. Most garage door springs are torsion springs, wound tightly above the door frame. Over time, metal fatigue sets in. Springs typically last 7 to 9 years with normal use, but wear accelerates if your door opens and closes 4 or 5 times daily.
Weather plays a role too. Here in National City, our heat can stress springs faster than cooler climates. Rust develops on the spring rod. Lack of lubrication speeds up the breakdown. And sometimes a manufacturing defect catches up with the original installation after a few years.
The moment a spring snaps, your garage door becomes a 300 to 400-pound weight that the opener cannot lift. The motor will strain, but the door stays put. That's when most folks call us.
Never attempt to replace a snapped spring yourself. This isn't a DIY job, and I say that as someone who respects a homeowner's initiative. Torsion springs carry enormous tension, even when they're broken. Releasing that energy without the right tools can cause serious injury.
Extension springs are slightly less risky, but they're still under high load. If you mess with either type, you risk a broken arm, crushed fingers, or worse. Garage door springs in National City require licensed technicians because the liability and safety stakes are real. Our team at Garage Door National City carries the proper equipment and insurance to handle it safely.
The repair itself takes about an hour once we arrive. We'll inspect the spring, check the cable, and verify the door tracks are aligned. If one spring is gone, we often replace both as a pair so they wear evenly. An extension spring replacement costs less than a torsion spring replacement, but both are routine jobs for us.

Spring replacement cost depends on the type and condition of your door system. A torsion spring replacement typically runs $200 to $400 per spring, including labor. Extension springs are usually $150 to $300. These figures assume no hidden damage to cables, pulleys, or the header mount.
If the cable snapped at the same time (which happens), add another $100 to $150. If the door has an older opener that's struggling, you might need that upgrade too. That's why we always provide a free estimate before starting work. Our team will walk you through the numbers and explain what's necessary versus what's optional.

How long does a garage door spring replacement take? Most spring replacements take 45 minutes to an hour once we arrive at your home. The job includes inspection of cables, pulleys, and the door track to ensure everything is safe and aligned. Emergency calls may see us arrive within a few hours depending on our schedule.
Can I open my garage door manually if the spring is broken? Technically you can lift it by hand if the door is light and the tracks are clear, but it's risky. A broken spring means the door's full weight rests on you. We don't recommend it. Call us instead and stay safe.
Do both springs need replacement if only one breaks? Yes, we recommend replacing both springs as a pair. They wear at similar rates, and replacing one while the other is aging leads to uneven load distribution and premature failure of the remaining spring.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are more durable and efficient. Extension springs run parallel to the tracks and are older technology. Torsion is standard in modern homes and lasts longer.
Will my homeowner's insurance cover spring replacement? Most homeowner policies don't cover wear-and-tear failure. However, if a spring breaks due to a sudden accident or defect, contact your insurer. We can provide a detailed estimate for your claim.
