The Mistake That Starts Almost Every Story
It usually starts the same way. A spring snaps with a loud bang, the door won't budge, and a quick search turns up a video of someone swapping a torsion spring in twenty minutes with a couple of wrenches and some winding bars. The part itself costs somewhere in the $20 to $50 range. Paying a technician can run several hundred dollars once labor is included. The math looks easy, the video makes it look easy, and most people have a cordless drill and a free Saturday. So they order the spring and figure they'll save themselves the bill.
Here's what the video doesn't capture: a standard torsion spring on a residential garage door is wound under roughly 25 to 35 turns of tension, storing enough energy to launch a winding bar across a garage like a javelin or slam a door shut on fingers, wrists, or a skull. It's not like replacing a mattress spring or a trampoline spring. It behaves more like a loaded crossbow bolted to the wall above your head.
What Actually Goes Wrong
The injuries that send people to the emergency room aren't rare freak accidents. They follow a handful of predictable patterns:
- The winding bar slips. If a bar isn't fully seated in the winding cone, or if someone uses a screwdriver instead of the correct bar, the spring can unwind in a fraction of a second. The bar becomes a weapon flying at face and chest height.
- The wrong spring for the door. Springs are rated by wire size, length, and wind direction. An incorrectly matched spring can fail under tension or leave the door dangerously unbalanced, which puts stress on the opener and the track.
- The door drops. With both springs disconnected or one side mid-adjustment, an unsecured door can free-fall. Fingers caught in a closing door, or a door falling on someone reaching underneath, cause crushed hands and broken bones regularly.
- Old, rusted hardware shears off. After years of Georgia humidity, summer storms, and the occasional ice event, spring anchor brackets and set screws corrode. What looks like a routine swap turns into hardware failing under load mid-repair.
None of this requires bad luck. It just requires one missed step on a job that has very little margin for error.
What Actually Prevents It
If you take nothing else from this, take these:
- Never work on a torsion spring with the door raised and unsupported. The door must be fully closed, and even then, the springs under tension are the danger, not the door's weight alone.
- Only use properly sized winding bars, never screwdrivers, pliers, or anything improvised. The bars need to fit the winding cone holes exactly and stay fully inserted through the entire wind or unwind.
- Clamp the shaft and secure the door with locking pliers at the track before touching the springs. This stops the door from suddenly dropping while you're working above it.
- Replace both springs together, even if only one broke. Mismatched age and tension on a two-spring system throws off balance and shortens the life of the new spring.
- Know your spring type before ordering parts. Torsion springs mounted above the door and extension springs mounted along the horizontal tracks fail differently and require different handling. Guessing wrong means starting over, or worse, installing something unsafe.
- Stop if anything looks corroded, bent, or doesn't match what the video shows. Real garages aren't demo units. Years of humidity and seasonal temperature swings change how hardware behaves, and that's exactly where injuries happen to people following a tutorial step by step.
Heading into the colder months, there's an added wrinkle. Cold snaps and the occasional ice event make steel more brittle and less forgiving, so a spring that's already fatigued from a long, humid summer is more likely to fail suddenly rather than gradually. If your door has been making a hard grinding or popping noise, or if it's felt heavier to lift by hand over the last few weeks, that's a sign the spring is weakening before it breaks outright, not after.
When to Call McDonough Garage Door
If a spring has already broken, or you've noticed the door getting harder to lift, sagging unevenly, or making a sharp bang followed by the door refusing to open, that's the time to call rather than reach for winding bars. Our Spring Replacement service includes identifying the correct spring type and size for your specific door, replacing both springs as a matched set, and rebalancing the door so your opener isn't working overtime to compensate. If the spring let go outside normal business hours and the door is stuck open or closed with a car trapped inside, our Emergency Garage Door Service covers exactly that kind of situation, with a technician who shows up with the right tools and the right spring the first time.
We serve McDonough, Stockbridge, Locust Grove, Hampton, Conyers, Covington, Jonesboro, and Griffin, and we'd rather answer a quick question over the phone than have someone attempt a repair that sends them to the ER instead. If your spring has snapped or sounds like it's about to, give McDonough Garage Door a call and we'll get it handled safely.
