In our 15 years serving National City, we've seen this problem again and again: a homeowner's garage door suddenly won't open, and they discover a snapped spring. A broken spring is one of the most common garage door failures, and it's rarely something you can ignore or delay. The good news? It's fixable, often on the same day you call.
Your garage door weighs between 300 and 600 pounds. Springs do the heavy lifting. A torsion spring (mounted above the door) or extension springs (on either side) counterbalance that weight, making it possible for your opener to lift the door smoothly. Springs typically last 7 to 9 years, depending on use and climate. Here in National City, our coastal salt air and temperature swings accelerate wear. See our guide on how national city.
When a spring snaps, it usually happens suddenly. You'll hear a loud bang or pop, and the door either won't budge or feels dangerously heavy. Don't try to force it open with the opener. Doing so can damage the motor and create a safety hazard.
Rust is enemy number one in our area. Salt air corrodes metal faster than most homeowners realize. Friction and repeated cycling also take their toll. A door that opens and closes 10 times daily will wear springs faster than one used 3 times daily. Poor maintenance accelerates failure too. Springs that haven't been lubricated or inspected in years are more prone to snap without warning. Read about smart garage door technology in national city: is it worth the cost?.

Torsion springs mount horizontally above your door. They twist and unwind to lift the door. One snapped torsion spring usually means the whole spring needs replacement, because the remaining spring can't handle the load alone. Replacing just one creates an imbalance.
Extension springs run along the sides of the door. They stretch and contract. If one breaks, you might be able to limp along temporarily, but both should be replaced together for safety and balance. Extension springs are generally cheaper to replace than torsion springs, but the labor is similar.

When you call Garage Door National City about a snapped spring, we assess whether repair is enough or if replacement is smarter. If your springs are original to the door and your garage door is 10 or more years old, replacement usually makes more sense than repair. New springs come with a warranty and buy you another 7 to 9 years of reliable operation.
If your springs are relatively recent and well-maintained, repair or replacement of just the broken component might be the way to go. We'll give you a transparent estimate and explain the trade-offs.

Spring replacement costs typically range from $200 to $400 per spring, plus labor. Torsion springs are usually at the higher end. Emergency or same-day service may add a trip fee. Our pricing guide walks through typical costs for National City homeowners, and we always provide a free estimate before we start work.
Regular maintenance catches spring wear before it becomes a failure. We recommend annual inspections, especially if you live near the coast like we do here in National City and nearby Chula Vista. Lubricate springs annually with a silicone-based lubricant (not WD-40). Check for rust spots or visible wear. If you notice your door is getting harder to open or closing unevenly, call us right away.

Call us at (619) 949-2754 to book your same-day appointment. Broken springs are urgent, but they're completely manageable when you have the right crew on your side.
How do I know if my spring is broken? Your door won't open, feels extremely heavy, or you heard a loud bang. The door may hang unevenly. Never force the opener. Call a professional to confirm and repair.
Can I replace a garage door spring myself? Not safely. Springs carry thousands of pounds of tension. Improper handling can cause serious injury or property damage. Always hire a licensed technician.
How long does spring replacement take? Most jobs are finished within 1 to 2 hours. Same-day service is usually available for National City customers who call before mid-afternoon.
Do both springs need to be replaced at the same time? Yes, for torsion springs. For extension springs, it's best practice to replace both even if only one broke. Mismatched springs cause imbalance and wear.
What's the difference between a repair and replacement? Repair fixes the broken component. Replacement installs a new spring. If springs are old or worn, replacement is smarter long-term than repeated repairs.
