How to tighten garage door springs?


Garage door springs play a crucial role in the smooth operation of your garage door. Over time, these springs may become loose, leading to issues such as difficulty in opening or closing the door. In this article, we will explore the steps involved in tightening garage door springs, ensuring the safety and functionality of your garage door.

Types of Garage Door Springs

Before diving into the process of tightening garage door springs, it’s important to understand the two main types of springs commonly used in garage doors: torsion springs and extension springs.

Torsion Springs: Torsion springs are typically mounted above the garage door and use torque to assist in lifting the door. They are wound tightly and store energy when the door is closed, releasing it to help lift the door when opened.

Extension Springs: Extension springs are usually located on either side of the garage door and stretch or extend to provide the necessary force for opening and closing the door. They work by counterbalancing the weight of the door.

Safety First

Before attempting to tighten garage door springs, it is crucial to prioritize safety. Garage door springs are under high tension and can cause serious injury if mishandled. Ensure you have the necessary tools and protective gear, such as safety glasses and gloves, before proceeding.

Identifying the Problem

The first step in tightening garage door springs is to identify the specific problem. Is the door not closing properly? Is it difficult to open? By understanding the symptoms, you can determine whether the springs need adjustment or replacement.

Tightening Torsion Springs

To tighten torsion springs, follow these steps:

1. Secure the door: Before working on the springs, ensure the garage door is fully closed and secured in place using clamps or locking pliers.

2. Release tension: Using a winding bar, insert it into one of the winding cone holes on the torsion spring. Slowly and carefully release the tension by turning the winding bar in the opposite direction of the spring’s wind. Repeat this process for the other winding cone.

3. Adjust the tension: To tighten the torsion springs, use the winding bars to turn the cone in the direction of the spring’s wind. Make small adjustments and test the door’s operation after each adjustment until the desired tension is achieved.

4. Secure the set screws: Once the desired tension is reached, secure the set screws on the torsion tube to prevent the springs from unwinding.

Tightening Extension Springs

To tighten extension springs, follow these steps:

1. Secure the door: Close the garage door and secure it in place using clamps or locking pliers.

2. Identify the cables: Extension springs are connected to the door through cables. Locate the cables and identify the S-hook or pulley system that attaches the cables to the track.

3. Adjust the tension: To tighten the extension springs, you will need to adjust the S-hook or move the cable to a higher hole on the track. This will increase the tension in the springs. Make sure to adjust both sides of the door evenly.

4. Test the tension: After making the adjustments, test the door’s operation to ensure it opens and closes smoothly. If necessary, make further adjustments until the desired tension is achieved.


Tightening garage door springs is a task that requires caution and attention to detail. By understanding the type of springs in your garage door and following the proper steps, you can ensure the safe and efficient operation of your garage door.
