The Mistake That Starts It All
It usually starts the same way: a spring snaps, the door won't budge, and a quick search turns up a ten-minute video making it look like a two-wrench job. The parts cost maybe thirty or forty dollars. The labor to have someone else do it can run into the hundreds. So the math feels obvious — why pay for something that looks this simple?
Here's what the video doesn't show you: that spring is holding back the entire weight of your garage door, wound so tight it's storing hundreds of pounds of force in a coil the size of your forearm. That stored energy doesn't care how careful you are. It cares whether you know exactly what you're doing, and most people learning from a ten-minute clip don't.
What Actually Goes Wrong
Garage door springs come in two types, and both can hurt you in different ways.
- Torsion springs sit on a metal bar above the door and are wound using steel winding bars inserted into a cone. If a bar slips, or if someone uses the wrong size bar, or a screwdriver instead of a proper winding bar, the cone can spin loose with enough force to break fingers, fracture an arm, or launch the bar across the garage like a dart.
- Extension springs run along the horizontal tracks and stretch under tension. Without a safety cable threaded through them, a failed extension spring can fire the broken coil and attached hardware across the garage at speeds fast enough to shatter drywall, crack a windshield, or cause severe facial and eye injuries.
Emergency rooms see a steady stream of these injuries every year: lacerations deep enough to need stitches, broken fingers from pinch points, concussions from a bar or spring making contact, and eye injuries from flying metal fragments. The door itself is also a hazard — a garage door can weigh well over a hundred pounds, and without the spring properly tensioned or the door securely clamped, it can drop suddenly while someone's hands or head are underneath it.
Why South Florida Conditions Make This Worse
Heat and humidity don't just affect you — they affect the hardware. Springs here are exposed to swings in temperature, salt-laden air if you're anywhere near the coast, and moisture that speeds up rust. Corroded coils don't fail the way clean ones do; rust pits weaken the metal unevenly, so a spring can look intact right up until it isn't. That unpredictability is exactly what makes DIY spring work riskier in this climate than in a drier one.
It also matters that many garage doors here are built or reinforced to meet wind-load requirements for hurricane season. Heavier, wind-rated doors often use higher-tension springs to handle the extra weight, which means more stored energy waiting to release if something goes wrong during a repair.
What Actually Prevents an Injury
If you take nothing else from this, take these:
- Never loosen or remove a spring without fully releasing its tension first — and understand that for torsion springs, this means using two correctly sized winding bars, never a screwdriver, pliers, or anything improvised.
- Replace both springs at once, even if only one has broken. If one has failed from age or corrosion, the other is on the same timeline and likely to go next, often while someone's already working on the first.
- Clamp the door in place before doing any work near the springs or cables, so it can't drop unexpectedly.
- Never work alone on anything involving stored spring tension. A second person can get help fast if something slips.
- Check for rust and fraying regularly, especially after storm season or salty, humid stretches, and plan for replacement before a spring fails on its own schedule rather than yours.
- Leave torsion spring work to someone with the right tools — properly sized winding bars, clamps, and the experience to read how a spring is behaving as tension releases.
When to Call Wilton Manors Garage Door Pro
If a spring has snapped, if your door is sagging unevenly, or if you hear a loud bang followed by a door that won't open, stop trying to force it and call us. Our Garage Door Spring Repair service includes replacing both springs as a matched set, checking cables and rollers for related wear, and testing the door's balance so it's not straining the opener. We also offer Garage Door Maintenance & Tune-Up visits that catch rust and fatigue in springs and hardware before they turn into an emergency, which matters given how our humidity and salt air wear down metal faster than it would elsewhere.
If your garage door needs a spring repair or you want it inspected before the next storm cycle, call Wilton Manors Garage Door Pro. We serve Wilton Manors, FL and nearby communities, and we can usually get a technician out the same day.
