A garage door spring snapping can be a serious inconvenience and a potential safety hazard. Here’s a comprehensive guide on what to do when your garage door spring breaks, including safety measures, step-by-step instructions, and when to call a professional.

Immediate Steps to Take

Ensure Safety

  1. Stop Using the Door: Avoid operating the garage door. Using it can cause further damage and pose a safety risk.
  2. Disconnect the Opener: Unplug the garage door opener to prevent any accidental operation.

Understanding Garage Door Springs

Types of Springs

  1. Torsion Springs: Located above the door, they use torque to lift the door.
  2. Extension Springs: Found alongside the tracks, they stretch to provide lifting force.

Both types need to be in perfect working order to balance the door’s weight, making it easy to open and close.

Final Checks
