Types of Springs in Garage Door Spring Repair

There are 2 types of garage door springs that may need repair. Torsion springs are heavy duty springs mounted to a metal rod that runs parallel to the door. These springs load with a twisting action. The springs unwind when the door is open. Extension springs are lighter weight springs mounted above the horizontal portions of the door tracks. These gain tension as they are stretched out with cables and pulleys. These springs are suspended between two brackets, not mounted to a rod, like torsion springs. Each spring has a safety cable running through it to prevent injury if it suddenly releases.
