How are garage door tension springs adjusted?

The method for adjusting garage door springs depends on the type of garage door that is installed. The manufacturer should supply specific instructions on how to adjust them.

There are two different types of springs for garage doors: torsion and side-mounted. Torsion springs are located on the top of the door on a metal rod. They turn as the door is opened or closed. Side-mounted springs are large springs on the side that use the aid of pulleys to open the door. Adjusting the springs can be very dangerous and should only be attempted with the help of a professional.
