Garage Door Springs in San Marino: What to Do When One Snaps

2026-06-19 A2Z Garage Doors

A customer called last Tuesday morning. His garage door wouldn't budge. One torsion spring had snapped overnight, and he couldn't get his car out. By 10 a.m., we had him mobile again. A snapped garage door spring isn't just an inconvenience; it's a safety issue that demands immediate attention from a trained technician, not a DIY fix.

Why Springs Fail (And Why It Happens Fast)

Garage door springs are under enormous tension. A standard residential door weighs 300 to 400 pounds. That weight rests on springs rated to handle roughly 10,000 cycles. Most springs last 7 to 9 years with normal use. When they're done, they don't gradually weaken. They snap.

The culprits vary. Rust inside the spring barrel corrodes the steel from within. Salt air near the coast (hello, San Marino neighbors in Coronado and Imperial Beach) accelerates that corrosion. Temperature swings stress the metal. Poor lubrication creates friction that wears the coils thin. One morning, you hear a loud *bang* from the garage, and the door sits heavy on the tracks.

Once one spring breaks, the other is usually close behind. They wear together. If you've got a snapped spring, the remaining one is likely near the end of its life too. That's why we always recommend replacing both torsion springs at the same time, even if only one failed.

Two Types of Springs: Know the Difference

Your garage door uses one of two spring systems. Extension springs run along the sides of the door, above the horizontal tracks. They're easier to see and slightly cheaper to replace. Torsion springs sit horizontally above the door opening, wound tight on a shaft. They're more durable and hold better weight balance, which is why most newer homes in San Marino use them.

Both types can snap. Extension springs sometimes break when their cables fray and the spring loses tension. Torsion springs break from metal fatigue, usually in the middle of the coil. The repair cost differs slightly depending on which you have and the quality of the replacement. A free estimate helps you understand what you're facing before we start work.

What Happens When You Call

Here's the real talk. Never try to replace a snapped spring yourself. The tension is lethal. We've seen people seriously hurt trying to adjust or replace springs without proper equipment. Call a professional. When you reach Garage Door San Marino, we ask a few quick questions: Can you describe the sound you heard? Is the door stuck all the way down, partially open, or somewhere in between? Do you know roughly how old the door is?

Same-day service is standard for us in San Marino. We carry torsion and extension springs in common sizes, plus the tools and expertise to do the job safely. Most spring replacements take an hour or less once we're on site. We'll inspect the cables, tracks, and hardware while we're there. A snapped spring often means other components are due for attention.

Cost and What Affects the Price

Spring replacement costs between $150 and $300 per spring, depending on the type, quality, and whether you replace one or both. Labor runs another $100 to $150. Yes, it's tempting to replace only the broken one to save money. Don't. The second spring will fail within weeks or months, and you'll pay again.

If your door is older than 10 years, we often recommend upgrading to high-cycle springs rated for 15,000 or 20,000 cycles. They cost more upfront but last longer and reduce the chance of another emergency call. During your estimate, we'll lay out the options.

When to Call vs. When to Wait

If your spring snapped and the door is stuck, don't wait. A heavy door hanging on one spring or no springs can slip, crush a car, or injure someone. This isn't a "fix it this weekend" situation.

If you hear creaking or squeaking sounds when the door moves, that's a warning sign. Springs are fatiguing. That's the time to schedule a free quote before a break leaves you stranded. We service all neighborhoods in and around San Marino, often arriving within a few hours of your call.

Your garage door spring failure is an emergency we handle every week. Don't risk a DIY approach or delay. Phone us today at (619) 566-2904 or contact us online to book same-day service and get your door working safely again.

Frequently Asked Questions

How long does a garage door spring replacement take? Most spring replacements finish in under an hour once our technician arrives. We'll also inspect cables, tracks, and hardware to spot other wear.

Can I replace one spring instead of both? Technically yes, but we don't recommend it. Both springs wear together. Replacing only one means the second will likely fail within weeks, costing you another service call and more downtime.

What's the difference between torsion and extension springs? Torsion springs sit above the door and are more durable. Extension springs run along the sides above the tracks. Torsion springs cost slightly more but handle weight better and last longer.

Do you offer emergency service on weekends? Yes. We offer same-day service across San Marino and nearby areas, including weekends. Call (619) 566-2904 to check availability.

How often should springs be replaced? Most springs last 7 to 9 years with standard residential use (roughly 4 to 8 cycles daily). Heavier use or salt air exposure can shorten that lifespan. We'll advise during your inspection.
