A snapped garage door spring leaves you stuck at home or locked out of your garage. The good news: a professional can usually repair or replace it the same day you call. Springs are the hardest working part of your door system, and when they break, nothing moves until they're fixed.
Your garage door weighs 300 to 500 pounds. Two springs (or one, depending on your setup) support that entire load. Every time you open and close the door, those springs stretch and contract. Over time, metal fatigues. A spring typically lasts 7 to 9 years with regular use.
When a spring snaps, you'll hear a loud bang or crack. The door may drop suddenly, or it might refuse to move at all. Your opener will strain trying to lift a weight it can't handle alone. This is the moment to stop using the door and call for help.
There are two main types: torsion springs (mounted above the door on a metal rod) and extension springs (running along the sides). Both do the same job, but torsion designs are more common in newer homes and tend to last longer.
You might find videos online showing how to replace a garage door spring yourself. Don't attempt it. Springs hold enormous tension, even when the door is closed. If a spring slips during removal or installation, it can cause serious injury. Professional technicians use specialized tools and safety equipment for a reason.
Sanbornton Garage Doors and shops across the region see preventable injuries every year from spring failures gone wrong. The repair cost isn't worth risking your fingers, hands, or eyes. A licensed professional gets the job done safely and backs their work.
If your door is currently stuck, our guide to garage door troubleshooting covers other possible causes and what to check before calling.
The cost of a spring repair depends on whether you need to replace one or both springs, and whether you're fixing a torsion or extension design. A single spring replacement typically runs between $200 and $400, including labor. If both springs are worn, you should replace both at the same time, even if only one has snapped. This prevents the second spring from failing weeks later.
The good news: most spring jobs are same-day service. Call in the morning, and your door opens again by afternoon. We serve Sanbornton and nearby communities with quick turnaround times.

Don't wait for a snapped spring to act. Watch for these warning signs:
The door opens slower than usual. Your opener sounds like it's working harder. You notice rust or pitting on the spring rod. The door feels heavier when you manually push it up. Small gaps appear between coils on the spring itself.
Any of these point to springs nearing the end of their life. A maintenance tune-up catches wear early and can extend spring life by a year or two. Our seasonal maintenance guide explains what inspection includes and why it matters.
Springs work in tandem with your opener and safety features. A broken spring affects more than just the door. Your auto-reverse system and photo eyes rely on normal door movement to function properly. If a spring fails, those safety systems can't calibrate correctly, putting you and your family at risk.
If you're also experiencing opener issues, battery backup and smart features can help during outages. But the spring problem must be solved first.

Broken springs don't fix themselves, and they won't get cheaper with time. The sooner you act, the sooner your door works again.
How long do garage door springs last? Most springs last 7 to 9 years with normal residential use (about 3 to 5 openings per day). Heavier doors or more frequent opening shortens lifespan. Springs rarely wear out at the same rate, so replacing both springs together prevents a second failure soon after.
Can I open my garage door if the spring is broken? No. Do not force the door open or use the opener if a spring is snapped. The door is too heavy for the opener to lift alone, and you risk damaging the motor or crushing your hand. Wait for professional repair.
What's the difference between torsion and extension springs? Torsion springs mount horizontally above the door and twist to lift it. Extension springs run vertically along the door tracks and stretch. Torsion springs are more durable and common in newer homes. Extension springs are found in older installations and require additional safety cables.
How much does spring replacement cost? Single spring replacement typically costs $200 to $400, including labor. If both springs need replacement, expect $350 to $600. Cost varies by spring type and your location. Call for a firm estimate.
Can I prevent spring failure? Regular lubrication and annual inspections extend spring life. Avoid slamming the door or hitting it with objects. Keep the tracks clean and aligned. Professional maintenance catches early wear before a break occurs.
