How to Fix Gap on One Side of Garage Door

The garage door is one of the essential parts of your home. It’s what keeps your car safe from the elements and criminals. But, when there’s a gap on one side of the door, it can make the system less stable and more challenging. Many times, the gap is caused by a misaligned track. Other times, it could be due to a damaged roller. If you’re having this problem, don’t worry! We’re here to help you fix it.

Summary: If you notice a big, noticeable gap on one side of your garage door, there are a few things you can do to try and fix it. You can try to adjust the door’s hinges, or you can buy a new garage door.

Why Is There a Gap on One Side of My Garage Door?

There are many reasons why there might be a gap on one side of your garage door.

1. Installed Incorrectly

One potential reason your garage door isn’t working might be that it was installed incorrectly. If there’s a gap on one side of the door, that means the installer didn’t do their job right. You may need to call them back to fix the problem.

2. Worn Out Rollers

One possible reason your garage door has a gap on one side is because the rollers are worn out. The rollers enable the door to open and close smoothly, so if they’re worn out, it can cause the door to be unlevel and create a gap. You can replace the rollers yourself or hire a professional to do it for you.

3. Misaligned Tracks

If your garage door has a gap on one side, it may be because the tracks are misaligned. The tracks are the metal rails that the door rollers ride on, and they should be perfectly parallel to each other. If they are not, it can cause the door to bind or catch as it moves, which eventually leads to a gap forming on one side. You can usually tell if your tracks are misaligned if you see visible gaps or dents in them, or if the door seems to be struggling to move freely along them.

4. Broken Springs

If your springs are broken, there’s no way to fix the gap on one side of your garage door. You’ll need to replace them. This is a job for a professional, as it’s very dangerous to try to do it yourself. If you’re not sure what kind of springs your garage door has, the owner’s manual will have instructions on how to find them. There are two main types: torsion springs and extension springs. Torsion springs are mounted on a shaft above the door and are wound up with a handle. Extension springs are attached to brackets on either side of the door and stretch along the tracks when the door is opened.

5. Worn Out Rollers

The most common reason for a garage door gap on one side is worn-out rollers. Over time, the rollers can become worn down and unable to support the weight of the door properly, causing the door to sag on one side. This is a job for a professional as it requires special tools and knowledge to replace the rollers correctly.

6. Sagging Door Section.

If your garage door is sagging on one side, it could be due to a problem with the door section. The door section is the portion of the door that rolls up and down when you open and close it. Over time, the door section can become warped or bent, which can cause it to sag on one side.

A Step by Step Guide on How to Fix Gap on One Side of Garage Door

Step 1: Find Out the Root Cause of the Gap

Before you can take steps to fix the gap on one side of your garage door, it’s essential first to determine what is causing the issue. In some cases, the gap may be due to the settling of your home, which can cause the door frame to become slightly misaligned. Other common causes of a gap include:

  • Incorrect installation of the door
  • Worn out or damaged weather stripping
  • Loose or missing screws

Step 2: Inspect the Door Frame

Once you’ve determined the root cause of the problem, it’s time to look at the door frame itself. Begin by inspecting the trim around the outside of the door to see if it is level. If not, use a level to make any necessary adjustments. Next, check if the caulking around the door is cracked or missing in many areas. If so, use a caulking gun to apply new caulk to these areas.

Step 3: Check the Weather Stripping

In many cases, gaps on one side of the garage door can be caused by worn-out weather stripping. To check the condition of your weather stripping, open the door and take a close look at the seal between the door and the floor. If you notice any cracks or tears in the weather stripping, it will need to be replaced.

Step 4: Tear Off Old Weather Stripping

Once you’ve located the damaged weather stripping, use a screwdriver or hammer to remove the old seal. Be sure also to remove any nails or screws that are holding it in place. Once the old weather stripping has been removed, clean off the area around the door frame with a rag to remove any dirt or debris.

Use a Screwdriver

Step 5: Install New Weather Stripping

With the area around the door frame clean, installing the new weather stripping is time. Begin by cutting the new seal to size using a measuring tape and utility knife. Next, place the new seal and use a hammer and nails or screws to secure it. Finally, use a drill and socket set to tighten any loose screws.

Step 6: Check The Seal Placement and Nail It

As you install the new weather stripping, check that it is correctly sealed around the door. Then, use a caulking gun to apply an additional sealant as needed. Once the seal is in place, use a hammer and nails or screws to secure it. Finally, use an adjustable wrench to tighten any loose screws.

Step 7: Adjust Your Limit Switches

If the gap on one side of your garage door is still not closing correctly, it may need to be adjusted. First, you’ll need to locate the limit switches on your opener unit. These switches are typically located near the unit’s base and have two adjustment screws. Once you’ve located the screws, use an adjustable wrench to turn them clockwise or counterclockwise until the door closes properly.

Step 8: Apply Caulk around the Door

Once you’ve taken all of the necessary steps to fix the gap on one side of your garage door, applying fresh caulk around the door frame is essential. This will help seal the door further and prevent any future gaps from forming. Use a caulking gun to apply the caulk around the door’s perimeter.

Step 9: Test The Door

After you’ve applied the caulk, test the door to ensure that it is closing properly. If not, make any necessary adjustments until the door is functioning correctly. By following these simple steps, you can fix a gap on one side of your garage door and keep your home safe and secure.

Tips and Tricks

If the gap is still not even after following the above steps, you may need to:

  • Adjust the bottom brackets. These are the black pieces of metal that hold the roller on either side of the door.
  • Loosen the screws or bolts (but don’t remove them) that hold the bracket in place, and then tap the bracket with a hammer until it is flush against the side of the door.
  • Tighten the screws or bolts back up, and check to see if the gap is gone.
  • If your garage door has springs on either side, you may need to adjust these. To do this, you will need to:
  • Locate the adjustment screws or nuts on either side of the door.
  • Turn the screws or nuts until the gap is gone.

How to Maintain a Garage Door

If your garage door isn’t working correctly, it can be a real pain. Not only is it inconvenient, but it can also be dangerous. A malfunctioning garage door can cause serious injury to you or your family.

That’s why it’s so important to keep your garage door in good working condition. By taking some simple steps, you can prevent many common problems.

1. Inspect the Door Regularly

Check the door every month or so to see any signs of wear and tear. In addition, it would be best to look out for any gaps on one side of the door. If you notice any of these problems, it’s time to take action.

2. Clean the Tracks

The tracks that your garage door runs on can get dirty and dusty over time. This can cause the door to stick or jump as it moves along the tracks.

To clean the tracks, first, remove any debris or dirt that you see. Then, use a soft cloth to wipe down the tracks. If there is any built-up grease or grime, you can use a mild soap to remove it.

3. Lubricate the Door

If your door is making a lot of noise, it may be because it needs to be lubricated. Check the manufacturer’s instructions to see what kind of lubricant to use. You may need to apply it to the hinges, rollers, and tracks. Be sure to get any areas that seem to be rusting as well.

4. Adjust the Sensors

If your garage door doesn’t close all the way, check the sensors. These are usually located at the bottom of the door on both sides. If they’re not aligned properly, they can prevent the door from closing completely. Realign them by loosening the screws and moving them until they’re in the correct position.

Check the Sensors

5. Tighten the Hardware

If your garage door is still not balanced, the hardware will likely lose. Check all the bolts and screws on the door to make sure they’re tight. If any are loose, tighten them with a wrench or a screwdriver. You may need to adjust the tracks if they’re loose as well. Once you’ve tightened all of the hardware, try opening and closing the door again to see if it’s balanced.

6. Check for Damage

If you find that there is damage to your garage door or tracks, this could cause the issue. If the door is visibly warped or bent, it will need to be replaced. The tracks may also be damaged if they are bent out of shape. In this case, you will need to replace them as well.

By taking these simple steps, you can keep your garage door in good working condition. This will help to prevent serious injuries and make your life much easier.

Frequently Asked Questions

Why is There a Gap on One Side of My Garage Door?

The answer is actually quite complex. In most cases, there is usually a gap on one side of your garage door because this area experiences more stress and wear than the other side. The weight of the car and snow or ice that accumulates on the heavier side causes it to sag lower than the thin-walled section on the lighter side.

This creates an opening that allows wind and rain into your garage while preventing snow or debris from entering. Over time, this space can grow larger due to weathering and expansion of mold or mildew.

What Causes Garage Door to Close Uneven?

One common issue is that the springs may be worn out, which can cause the door to close slowly or not at all. You might also have a sag in the door’s chain or cable, which can cause it to sag when opened. Finally, if the door is not properly sealed against air and moisture infiltration, it may become wobbly and close unevenly. In all cases, fixing the issue will require professional assistance from a garage door specialist.

Should a Garage Door Be Balanced?

While it is not necessary to have your garage door balanced, doing so can help to ensure that it operates smoothly and quietly. Garage doors are heavy and can cause serious damage if they’re not properly installed or maintained. By balancing the weight of the door, you can avoid operator fatigue caused by uneven motion and reduce the chances of garage door repairs or replacements in the future.

Additionally, balancers measure how much tension is put on each side of a garage door contact block (usually steel plates) over time as pounds act against them in an effort to open or close the gate while minimizing creaking noise. This type of maintenance helps keep your gate operating smoothly at all times and prevents any sudden changes in pressure that could potentially damage your hinges or springs.

What Happens if You Over Tighten a Garage Door Spring?

If you over tighten a garage door spring, it can cause the garage door to close too quickly, damaging the door and potentially leading to serious injuries. If you’re not sure how to properly tighten a garage door spring, be sure to consult a professional.


If you are having trouble with your garage door, don’t worry. There is a fix for that. We have outlined the steps you need to repair the gap on one side of your garage door. Follow these instructions, and you will be able to have a properly functioning garage door once again. We hope you find this article on how to fix gap on one side of garage door helpful.
