Garage Door Springs in Bunnell: Why They Snap and What Repair Really Costs
2026-09-02 7 min read
A customer called last Tuesday morning. His garage door wouldn't budge. One look at the spring above the door told me everything: it had snapped clean in half, and the whole assembly was sagging. He'd heard a loud bang the night before but thought it was thunder. That's the story I hear at least twice a week around Bunnell. Springs fail silently until they don't, and when they go, your door goes with them.
Understanding Garage Door Springs in Bunnell
Two types of springs handle the real work on your garage door: torsion and extension springs. Torsion springs sit horizontally above your door and twist to lift the weight. Extension springs run along the sides and stretch to help raise the panel. Both are under enormous tension, storing enough energy to lift 400 to 600 pounds. That's why a snapped spring isn't just an inconvenience. It's a safety issue and a repair that demands professional hands.
Springs typically last seven to nine years with normal use. But humidity, temperature swings, and constant cycling wear them down faster than you'd expect. Here in Flagler County, where we get salt air and moisture year-round, springs corrode from the inside out. You won't see it happening until the break happens.
Why Springs Fail Without Warning
A spring under constant tension develops micro-fractures over time. Rust accelerates the process. One final cycle, one cold morning, one extra opener activation, and the metal gives up. The sound is unmistakable: a sharp crack that echoes through your garage and sometimes your whole house.
The real danger? A snapped torsion spring means the door opener is now fighting a 400-pound dead weight. That's when garage doors come down hard, or worse, get stuck halfway. If a safety cable (the thin steel line running alongside the spring) isn't there to catch the broken spring, metal can fly. That's why I've always told homeowners: never try a DIY spring replacement.
If your door is stuck or won't open, check the garage door stuck service guide for what actually happens during an emergency visit.
Repair Cost and What Affects Your Price
A snapped spring repair in Bunnell runs anywhere from $200 to $400 for a single spring replacement, plus labor. If both springs have failed (common on older doors), you're looking at $400 to $600 total. The estimate depends on spring type, door size, and whether we're replacing one or both.
Extension springs are cheaper to replace than torsion springs because they're simpler and less risky to handle. But torsion springs, while pricier, are more durable long-term. If your door is older and both springs are original, replacing both at the same time saves money later because matching springs fail at similar times.

Labor typically adds $100 to $150 per hour, and a spring job takes about an hour for a single spring, longer if we're doing both. Some companies charge a service call fee upfront, which I've never done. We quote a flat repair cost after we see the door.
Prevention: Making Springs Last Longer
Regular maintenance cuts years off the wear cycle. That means lubricating springs twice a year with a light silicone spray, not WD-40 or heavy oils that trap dirt. It means keeping your garage reasonably dry, especially during humid months. It means not hammering your door opener with extra force if the door feels heavy. All of that adds life.

If your opener is also making noise or struggling, there might be more going on than just the springs. We've written about what that sound really means in another post.

Frequently Asked Questions
How do I know if my spring is broken? The door feels heavy, won't open, or you heard a loud bang. Look above the door for a visible gap or twisted metal. Never force the opener if the door feels wrong.
Can I open my garage door manually if the spring is broken? Not safely. A broken spring means the door is now 400 plus pounds of unbalanced weight. Manual operation risks crushing your hands or the door dropping unexpectedly.
How long does a spring replacement take? Most jobs take 45 minutes to an hour. Both springs take longer. We'll give you a time estimate when we arrive.
Do both springs need to be replaced if only one snapped? Not always, but often yes. If springs are the same age and both original, replacing both prevents a second failure weeks later. We'll recommend based on what we find.
What's the difference between torsion and extension springs? Torsion springs twist above the door. Extension springs stretch on the sides. Torsion springs last longer and are safer but cost more. Extension springs are cheaper but wear faster.
