How do I know if my garage door springs need to be adjusted?
Here are a few signs that you might need a spring adjustment:

- The garage door doesn’t close fully, or closes unevenly, leaving one side open.
Which way do you wind a garage door spring?
This is pretty easy to determine. Basically, door springs can either wind to the left or to the right. Right-hand winding springs wind in a clockwise manner with the end wire on the right, while left-hand winding springs go anticlockwise with their end wire on the left.
