How to balance a garage door?


Balancing a garage door is essential for its proper functioning and longevity. A balanced garage door not only operates smoothly but also reduces the risk of accidents and prevents unnecessary strain on the door opener. In this article, we will explore the steps involved in balancing a garage door to ensure optimal performance and safety.

Understanding Garage Door Balance

Before we delve into the process of balancing a garage door, it is crucial to understand what it means for a door to be balanced. A balanced garage door is one that remains in position at any point along its travel path without falling closed or flying open. Achieving this balance requires equal tension on both sides of the door, allowing it to stay in place when partially opened.

Tools and Materials

To balance a garage door, you will need the following tools and materials:

1. Winding bars: These metal bars are used to apply torque to the torsion springs.
2. Adjustable wrench: Used for loosening and tightening nuts and bolts.
3. Ladder: Provides access to the garage door and its components.
4. Safety glasses and gloves: Protects you from any potential hazards.
5. Tape measure: Helps in taking accurate measurements.
6. Level: Ensures the door is properly aligned.

Steps to Balance a Garage Door

1. Disconnect the opener: Start by disconnecting the garage door opener to prevent any accidental activation during the balancing process. This can usually be done by pulling the release cord or lever.

2. Identify the problem side: Determine which side of the door is causing the imbalance. This can be done by manually opening and closing the door and observing any uneven movement or resistance.

3. Adjust the tension of the torsion springs: Torsion springs are responsible for counterbalancing the weight of the garage door. To adjust the tension, insert the winding bars into the winding cone of the spring and apply slight pressure in the opposite direction of the winding. Turn the winding cone in small increments until the tension is equal on both sides.

4. Test the balance: Once you have adjusted the tension, manually open the door to the halfway position and release it. A balanced door should remain in place without moving up or down. If it moves, repeat the adjustment process until the door stays in position.

5. Check the alignment: Use a level to ensure that the garage door is properly aligned both horizontally and vertically. Adjust the track brackets if necessary to achieve the correct alignment.

6. Lubricate moving parts: Finally, lubricate all moving parts of the garage door, including hinges, rollers, and tracks. This helps reduce friction and ensures smooth operation.


Balancing a garage door is a crucial maintenance task that promotes smooth operation, extends the lifespan of the door, and enhances safety. By following the steps outlined in this article, you can effectively balance your garage door and enjoy trouble-free operation for years to come.
