A well-functioning garage door is necessary for security and energy efficiency. However, it’s time to take action if you’ve noticed gaps on the sides. These gaps can lead to issues like drafts, pest invasions, and even increased energy bills.
But what causes these side gaps in the first place? We’ll help you understand the cause so you can find a solution. Whether you’re a DIY enthusiast or just looking for some guidance, this blog will tell you how to adjust a garage door side gap quickly and easily.
What Causes Side Gaps?
A side garage door gap can arise from a few common issues. Here’s a detailed list so you can troubleshoot the problem.
- Misaligned tracks.
- Worn or damaged weather stripping.
- Incorrect installation.

These factors can be combined or separated. The gaps can easily compromise both safety and energy efficiency in your home. This is why you must resolve the issue immediately before it escalates into a costly repair.
Misaligned Tracks
Misaligned garage door tracks are a common cause of side gaps. When the track that guides your door becomes crooked or out of alignment, it creates uneven spacing on one or both sides.
This misalignment can happen for various reasons. Regular wear and tear, accidental bumps from vehicles, or even environmental factors like shifting ground can all contribute to track issues.
When the tracks aren’t perfectly aligned, they prevent the door from sealing tightly against the frame. This leaves gaps but also affects energy efficiency and security. Hence, you should examine the track’s vertical and horizontal sections closely. Small tweaks can make a significant difference in resolving the issue.
Worn or Damaged Weather Stripping
Weather stripping is another important factor in maintaining your garage door’s efficiency. Over time, exposure to the elements can take its toll on this protective barrier. Worn or damaged weather stripping can lead to noticeable gaps along the sides of your door. It not only affects insulation but also allows pests and debris to enter.
This is why you should inspect the condition of the weather stripping as part of your regular maintenance routine. Look for cracks, tears, or areas that appear brittle. If you notice any signs of wear, it’s time for a replacement.

However, installing new weather stripping is straightforward, so you don’t have to worry. It can also significantly enhance energy efficiency. Choose materials that are durable and suitable for your climate conditions.
Incorrect Installation
When a door isn’t aligned properly, it may not seal effectively against the frame. This creates openings that allow air, pests, and even water intrusion.
One common issue is the way the tracks are mounted. The door’s movement becomes uneven if they’re not level or parallel. This misalignment causes gaps on one or both sides. Another factor is the positioning of the hinges and rollers. They need precise alignment to ensure smooth operation. Misplaced components can exacerbate those annoying side gaps.
During garage door installation, you need to follow guidelines closely for optimal results. Any oversight could mean dealing with adjustments later on, which is sometimes more complicated than fixing simple gaps initially would have been.
How to Fix Side Gaps?
Now that you know the reasons behind the issue, let’s see how to fix side gaps in your garage door. You should start by inspecting the tracks. Look for any misalignment that could cause the door to sit unevenly. If you notice a problem, loosen the screws and adjust the track until it aligns properly. Tighten everything back up securely.
Next, check the weather stripping along the sides of your garage door. If it’s worn or damaged, replace it with new material or use a garage door side seal. And if adjustments don’t solve the issue, examine how your garage door was installed. You may need to re-hang or reposition sections of the door frame.

Always remember safety first when working on your garage door. Use proper tools and wear protective gear if necessary while making these fixes.
When Do I Need a Garage Door Repair Company?
Sometimes, fixing side gaps can be a straightforward DIY task, and you only need a garage door gap filler. However, there are times when the situation calls for professional garage door help.
