How Does a Garage Door Spring Work

Garage door springs are mechanical devices that are used to balance the weight of a garage door and make it easy to open and close. The most common types of garage door springs are torsion springs and extension springs. Torsion springs are typically mounted on a metal shaft above the garage door, while extension springs are mounted on either side of the door. These springs use the principles of torque and tension to lift the door. In this article, we will explain in detail the working mechanism and different types of garage door springs available.

Types of Garage Door Springs and How They Work

Torsion Springs

Torsion springs are the most common type of garage door spring. They are mounted on a metal shaft above the garage door and work by twisting and untwisting as the door moves. These springs are under a high amount of tension, which helps to lift the door. When the door is closed, the springs are wound tight, and when the door is open, the springs are relaxed. Torsion springs come in different sizes and can be adjusted to suit the weight of the door.

Extension Springs

Extension springs are another type of garage door spring that is mounted on either side of the garage door. They work by stretching and contracting as the door moves. These springs are also under tension and help to lift the door. Extension springs are less common than torsion springs, but they can still be found in some garage door systems.

Safety Precautions for Garage Door Springs

Garage door springs are under a significant amount of tension, and if not handled correctly, they can be dangerous. To ensure your safety when working with garage door springs, it is essential to follow these safety precautions:

  • Only experienced technicians should adjust or replace garage door springs. Attempting to do so without proper training and knowledge can lead to injury or damage to the garage door.
  • Always wear protective gear, including safety glasses and gloves, when working with garage door springs.
  • Never attempt to remove or install garage door springs under load.
  • Use caution when handling and disposing of old garage door springs, as they can be dangerous if not handled properly.
  • Keep children and pets away from the garage door and its springs when adjusting or replacing them.
  • Do not attempt to lubricate or paint garage door springs, as it can damage them and make them less effective.
  • Regularly check for signs of wear and tear on your garage door springs, such as rust or cracking, and have them replaced if necessary.
  • In case of an emergency, always have a professional garage door technician come and have a look at the door; never try to fix it yourself.


Following these safety precautions will help ensure your safety and prevent accidents when working with garage door springs. Remember, it is always better to be safe than sorry.
