How to Fix Gaps on Side of Garage Door


Garage doors are an essential part of any home, providing security and convenience. However, over time, gaps may start to appear on the sides of the garage door, allowing dust, pests, and even rainwater to enter the garage. This can compromise the insulation, increase energy costs, and create an unpleasant environment. In this article, we will discuss some effective tips and techniques to fix these gaps and restore the functionality and appearance of your garage door.

Identify the Cause

The first step in fixing gaps on the side of your garage door is to identify the root cause. Common causes include worn-out weatherstripping, improper installation, loose hinges, or damaged panels. Take a close look at the door to determine the exact cause, as this will help you choose the most appropriate solution.

Replace the Weatherstripping

Weatherstripping is a thin strip of rubber or vinyl that lines the sides and bottom of the garage door, creating a seal when the door is closed. Over time, weatherstripping can wear out or become damaged, leading to gaps. Measure the length of the weatherstripping required and purchase a replacement from your local hardware store. Remove the old weatherstripping and carefully install the new one, ensuring it fits securely along the sides of the garage door.

Adjust the Garage Door Tracks

If the gaps are caused by misaligned tracks, adjusting them can help resolve the issue. Start by loosening the screws that hold the tracks in place. Gently tap the tracks with a rubber mallet to align them properly. Use a level to ensure they are perfectly straight. Once aligned, tighten the screws securely.

Tighten Loose Hinges

Inspect the hinges on the garage door panels. If any hinges are loose, tighten them using a screwdriver or wrench. Loose hinges can cause the panels to shift, resulting in gaps along the sides. Ensure all hinges are securely fastened to prevent any movement.

Replace Damaged Panels

If the gaps persist despite the above measures, it is possible that the garage door panels themselves are damaged. In such cases, it may be necessary to replace the damaged panels entirely. Contact a professional garage door repair service to assess the situation and replace the panels if needed.

Maintain Regular Maintenance

To prevent future gaps from appearing, it is crucial to maintain regular maintenance on your garage door. Lubricate the moving parts, such as hinges and rollers, at least twice a year. Inspect the weatherstripping for any signs of wear and tear, and replace it promptly if necessary. Keeping your garage door in good condition will help prevent gaps and ensure its longevity.


Fixing gaps on the side of your garage door is important for maintaining the security and functionality of your garage. By identifying the cause and following the appropriate steps, such as replacing weatherstripping, adjusting tracks, tightening hinges, or replacing damaged panels, you can effectively eliminate these gaps and restore the integrity of your garage door. Remember to perform regular maintenance to prevent gaps from reoccurring and enjoy a well-functioning garage door for years to come.
