How to Adjust Garage Door Height?

Adjusting the height of your garage door is crucial for its proper operation and to ensure the safety of your home. If you’re in the Winnipeg area, consulting with experienced garage builders in Winnipeg can provide you with professional insights into the process. A garage door that doesn’t close or open correctly can be a security risk and may lead to further mechanical issues.

This comprehensive guide, along with advice from skilled garage builders Winnipeg, will walk you through the process of adjusting your garage door height, ensuring it operates smoothly and aligns perfectly with your garage floor.

Step-by-Step Guide to Adjust Garage Door Height

Adjusting the height of a garage door involves several steps, from preparation to the final testing. Each phase is important to achieve the desired functionality and safety.

Step 1: Setting Up

Safety first. Before starting to brace a garage door, ensure your garage door is in the closed position and disconnect the power to the garage door opener to prevent any accidental operation. Bracing your garage door will enhance its strength and durability, especially in areas prone to high winds or storms.

Gather the necessary tools, such as a ladder, wrenches, and a measuring tape, to complete the bracing process. It’s also advisable to have someone assist you during the process to ensure safety and efficiency. This teamwork will make the installation of the garage door brace smoother and quicker.

Step 2: Finding the Height Adjustment Screws

Locate the height adjustment screws on your garage door. These are usually found on the side tracks or near the bottom of the door and are used to adjust the door’s stopping point when it opens and closes.

The exact location can vary depending on the model and manufacturer of your garage door, so refer to your owner’s manual for specific details.

Step 3: Adjusting the Garage Door Height

To adjust the height, you’ll need to turn the adjustment screws. If your door closes too far, leaving a gap at the bottom, you’ll need to decrease the door’s closing height by turning the adjustment screws in the appropriate direction.

Conversely, if your door doesn’t close completely, you’ll need to increase the closing height. Make small adjustments and check the door’s operation after each one to avoid over-adjusting.

Step 4: Testing the Limits

After making the adjustments, it’s time to test the door. Before you reconnect the power, it might be a good idea to identify garage door manufacturer, as this can provide specific guidance for troubleshooting and fine-tuning your door’s operation.

Once you have this information, use the garage door opener to open and close the door. Observe its movement and ensure it stops at the correct positions.

If the door still doesn’t close properly, repeat the adjustment process. It’s crucial that the door seals against the floor to prevent pests and weather elements from entering your garage.

Step 5: Adjusting the Closing Height

Sometimes, you may need to adjust the closing force or limit. This is done to ensure that the door closes securely without exerting excessive force, which could lead to damages or safety hazards.

This adjustment is typically made on the garage door opener unit and should be done according to the manufacturer’s instructions to ensure the door operates safely and effectively.


Properly adjusting the height of your garage door ensures its efficient operation and longevity. It also enhances the security and energy efficiency of your home by preventing gaps and uneven closing.

While the process may seem daunting at first, following these detailed steps can help you achieve a well-functioning garage door. Remember, if you’re ever unsure about the process or encounter complications, it’s best to consult with a professional garage door technician to prevent damage or potential injuries.
