How to tighten a garage door spring?


Tightening a garage door spring is an essential maintenance task that ensures the smooth operation and longevity of your garage door. A properly tightened spring helps to balance the weight of the door, making it easier to open and close. In this article, we will discuss the step-by-step process of tightening a garage door spring and provide valuable tips to help you accomplish this task safely and effectively.

Understanding Garage Door Springs

Before diving into the process of tightening a garage door spring, 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 are wound tightly to store mechanical energy. When the door is opened, the springs unwind, releasing the stored energy to assist in lifting the door. To tighten a torsion spring, you will need to adjust the tension on the spring using winding bars.

Extension Springs: Extension springs are usually located on either side of the garage door and stretch or extend when the door is opened. These springs require adjustment by either tightening or loosening the tension on the springs using adjustment brackets.

Tightening Torsion Springs

To tighten a torsion spring, follow these steps:

1. Gather the necessary tools and materials: Before starting, make sure you have a pair of winding bars, safety glasses, and gloves to protect yourself during the process.

2. Secure the door: Close the garage door and secure it in place using clamps or locking pliers to prevent any accidental movement.

3. Identify the winding cone: Locate the winding cone on the torsion spring. The winding cone is typically found at the end of the spring and is attached to a stationary cone.

4. Insert the winding bars: Insert the winding bars into the holes on the winding cone. Make sure the bars are securely in place before proceeding.

5. Apply tension: Using the winding bars, apply tension to the winding cone by turning it in the direction that tightens the spring. This will increase the tension on the spring.

6. Measure the tension: Use a tension gauge to measure the tension on the spring. Refer to the manufacturer’s guidelines or consult a professional to determine the appropriate tension for your specific garage door.

7. Adjust as needed: If the tension is not within the recommended range, continue adjusting the winding cone until the desired tension is achieved.

Tightening Extension Springs

To tighten extension springs, follow these steps:

1. Ensure safety: Put on safety glasses and gloves before starting the process to protect yourself from any potential accidents.

2. Identify the adjustment brackets: Locate the adjustment brackets on both sides of the garage door tracks. These brackets are used to tighten or loosen the tension on the extension springs.

3. Adjust the tension: Using a wrench or pliers, turn the adjustment bolt or nut on each bracket clockwise to tighten the tension on the extension springs. Make sure to turn both sides equally to maintain balance.

4. Test the tension: After making adjustments, open and close the garage door to check if the tension is appropriate. The door should open and close smoothly without any imbalance or excessive resistance.

5. Repeat if necessary: If the tension is still not sufficient, repeat the process by tightening the adjustment bolts or nuts further. Be cautious not to overtighten the springs, as it can cause damage to the door or the springs themselves.


Tightening a garage door spring is an important maintenance task that ensures the proper functioning and longevity of your garage door. Whether you have torsion springs or extension springs, following the correct procedures and safety precautions is crucial. By understanding the different types of springs and following the step-by-step instructions provided, you can safely and effectively tighten your garage door springs.
