A garage door spring plays an essential role in smoothly lifting and lowering the door. These springs are typically located above the door and are under immense tension. When the garage door is closed, the springs are compressed, storing potential energy. As you initiate opening the door, this stored energy is released, causing the springs to expand and exert a force that counterbalances the weight of the door. This balance enables you to effortlessly lift the door with minimal effort. When you close the door, the springs once again absorb the energy, allowing for a controlled descent. This mechanism repeats every time you use the garage door, ensuring a reliable and efficient operation.
Torsion spring mechanics
A torsion spring is a type of spring that works by twisting or rotating, hence the name “torsion.” It is commonly used in garage doors to provide the necessary force to lift and lower the door.
The mechanics of a torsion spring are relatively simple. The spring is made up of a tightly wound metal coil, usually made of steel or other strong materials. This coil is then attached to a shaft, which is located above the garage door.
When the garage door is closed, the torsion spring is in a state of tension. This means that the coil is tightly wound and stores energy. As the door is opened, the spring begins to unwind, and the stored energy is released. This energy is what helps to lift the heavy garage door.
As the garage door is raised, the torsion spring continues to unwind, and the energy is transferred to the shaft. The shaft then rotates, pulling the cables attached to the door and causing it to lift. The tension in the torsion spring balances the weight of the door, making it easier to open and close.
When the door is fully open, the torsion spring is at its maximum state of unwinding and tension. At this point, the spring has transferred all of its energy to the shaft and the garage door is held in place.
To close the door, the process is reversed. The spring begins to wind back up as the weight of the door is transferred back to the spring. This winding action creates tension in the spring once again, which helps to lower the door gently and smoothly.
Torsion springs are designed to be extremely resilient and durable, as they undergo a lot of stress and tension during the opening and closing of the garage door. They are typically rated for a certain number of cycles, which represents how many times the door can be opened and closed before the spring may need to be replaced.
Overall, the mechanics of a torsion spring allow for the smooth and efficient operation of a garage door. Without this type of spring, it would be much more difficult and physically demanding to manually open and close a heavy garage door.
Types of Garage Door Springs
Garage door springs play a crucial role in the smooth operation and balance of your garage door. These springs are responsible for counterbalancing the weight of the door, making it easier to open and close. There are two main types of garage door springs: torsion springs and extension springs.
Torsion Springs
Torsion springs are the most common type of garage door springs used in residential properties. These springs are typically mounted horizontally above the garage door opening. They work by twisting or coiling tightly under tension when the door is closed and unwind when the door is opened. This creates a rotational force that helps lift the door.
One advantage of torsion springs is that they provide a smoother and more controlled operation compared to extension springs. They are designed to last longer and require fewer maintenance efforts. Additionally, torsion springs are generally considered to be safer because they are located near the top of the door, reducing the risk of accidents or injury.
However, torsion springs are more expensive to install and repair. They require precise measurements and specialized knowledge to properly adjust or replace. It is recommended to seek professional help when dealing with torsion springs to avoid any potential risks or damage.
Extension Springs
Extension springs are another common type of garage door springs, especially in older or budget-friendly garage door systems. These springs are mounted on either side of the door, parallel to the horizontal tracks. Unlike torsion springs, extension springs expand and contract to lift and lower the door.
One advantage of extension springs is their simplicity and affordability. They are easier to install and repair compared to torsion springs, making them a popular choice for DIY enthusiasts. Extension springs also provide a wider range of options for customization, allowing homeowners to choose the appropriate spring strength for their specific garage door.
However, extension springs can be more dangerous if not properly maintained or installed. Due to their location along the sides of the door, they are more exposed to potential damage or cause accidents. In case of a spring failure, extension springs can snap and release a significant amount of force, posing a risk of injury or property damage.
- Standard Extension Springs: These are the most common type of extension springs found in residential garage doors. They are typically placed on either side of the door and are calibrated to counterbalance the weight of the door.
- Clipped or EZ-Set Extension Springs: These springs feature a clip or bracket system that makes installation and adjustment easier. They are designed to reduce the risk of injury during installation or repair.
- Double-looped Extension Springs: As the name suggests, these springs have two coils instead of one. This design provides better stability and durability, making them ideal for larger or heavier garage doors.
It is important to note that both torsion springs and extension springs require regular inspection and maintenance to ensure their proper functionality. It is recommended to consult with a professional garage door technician if you have any concerns or issues with your garage door springs.

Knowing which type of spring you have will help you determine the correct method of tension adjustment.
- Step 2: Release the tension: If you have a torsion spring, you will need to release the tension before making any adjustments. This is typically done by inserting a winding bar into one of the winding cones and slowly turning it in the opposite direction of the spring’s winding. For extension springs, you will need to stretch the spring out to release the tension using a pair of pliers or a specialized tool.
- Step 3: Adjust the tension: Once the tension has been released, you can proceed with adjusting the tension to the desired level. To increase the tension, you will need to tighten the spring by winding it more or repositioning the hooks or clips that hold the spring in place. To decrease the tension, you will need to unwind the spring or reposition the hooks or clips to allow for less tension.
- Step 4: Test the door: After making the necessary adjustments, it is crucial to test the door’s operation. Open and close the door several times to ensure that it moves smoothly and evenly. If the door feels too heavy or unbalanced, further adjustments may be required.
Remember, improper tension adjustment can lead to serious accidents or damage to the garage door system.
