Why DIY Garage Door Spring Repair Sends People to the ER

A look at what actually happens when homeowners try to fix a broken garage door spring themselves, and the specific steps that keep that stored energy from turning into a trip to the hospital.

The Call We Get After Someone Already Tried It

A typical service call starts the same way: the spring snapped overnight, the homeowner watched a video, bought a winding bar from the hardware store, and got partway through before something didn't feel right. Sometimes we arrive to a door that's hanging crooked with cables off the drum. Sometimes we arrive to a homeowner icing a hand or holding a rag to a cut on the forearm. Occasionally the call comes from a family member, because the person who was working on the door is already at urgent care.

None of this is rare. Garage door springs are one of the few components in an ordinary house that store enough energy to break bones, and the repair looks deceptively simple from the outside.

What Actually Goes Wrong

A torsion spring sits above the door, wound tight enough to lift 150-400 pounds of door weight on cables. That tension doesn't go away when the spring breaks — it's still partially loaded, or the opposite spring on a two-spring setup is still fully wound. When someone removes the wrong bolt, uses a screwdriver instead of a proper winding bar, or lets go mid-wind, the bar can spin loose with enough force to break fingers, fracture a wrist, or strike the face and head.

Extension springs carry their own version of this risk. Without a safety cable running through the spring, a failure sends the spring itself flying across the garage like a projectile. We've replaced springs that left dents in drywall and cracked windshields on cars parked a few feet away.

How Badly People Get Hurt

  • Hand and finger injuries from winding bars slipping or cables unspooling under tension
  • Facial lacerations and eye injuries from spring fragments or recoiling hardware
  • Back and shoulder injuries from an unbalanced door dropping suddenly while someone is underneath it
  • Head injuries from a winding bar striking a ladder or the person, especially when working alone on an uneven garage floor

Salt air along the coast adds a layer most people don't think about: corrosion. A spring that's rusted from humidity and salt exposure doesn't fail cleanly — it can be weaker on one side of the coil, which means it unwinds unevenly and less predictably than a spring in a drier inland garage. That unpredictability is exactly what makes amateur winding attempts more dangerous here than the national average DIY video suggests.

What Actually Prevents This

  1. Don't remove the spring brackets without releasing tension first using properly sized winding bars, one at a time, never loose.
  2. Disconnect the opener and manually support the door before doing any work near the torsion assembly, so the door can't drop unexpectedly.
  3. Never use a screwdriver, wrench, or pliers as a winding bar. Winding bars are sized to the cone holes for a reason — anything else can slip.
  4. Keep the garage clear of kids, pets, and anyone standing in the door's travel path or spring line of force.
  5. Wear eye protection if you're anywhere near the spring assembly, even just to inspect it.
  6. Check for rust and pitting before storm season rather than after a spring has already failed — salt air and humidity accelerate wear on coils and cable ends faster than most people expect.

If you're seeing a gap in the coil, hearing a loud bang from the garage, or noticing the door suddenly feels twice as heavy to lift by hand, that's a spring telling you it's done. That's the moment to stop, not the moment to start troubleshooting with tools from the garage shelf.
