How to Adjust an Uneven Garage Door

1
TEST THE DOOR
Test the door - Adjust Uneven Garage Door
  • Move the garage door up and down until you find a place where the door stays suspended when you let go.
  • If that point is more than four-feet or less than three-feet above the ground, you will need to balance the door.
2
BRACE THE OPEN DOOR

  • Keep the door open, a few feet off the ground, as this takes the pressure off the door springs.
  • Put a ladder under the door to make sure it won’t close accidentally while you’re working on it.
3
MOVE THE SPRING WITHIN THE TRACK HANGER

Safety: To avoid injury, make sure the spring is completely free of tension before removing

  • Once the spring is free of tension, remove from its track hanger.
  • If the door was closing too quickly, move the spring to the next higher hole on the bracket.
  • If it was opening too quickly, move it to the next lower hole.
  • Adjust the springs on both sides of the door the same way.
  • Retest the door balance, as you did in Step 1.

CHECK THAT THE DOOR CLOSES EVENLY

  • Close the door and use a level to determine that it’s hitting the ground levelly on both sides.
  • If it doesn't, adjust the spring tension on each side of the door until it does.
5
ADJUST THE LIFT CABLE

  • To make fine adjustments, try adjusting the lifting cable instead of the spring.
  • The cable is attached to the door and runs to an S-hook that attaches to the track support.
  • With the door propped open, take the S-hook out of the support, and tighten or loosen the cable as needed.
