2. Misaligned Tracks

If your garage door tracks are misaligned, it may cause a gap. You can fix this problem by realigning the tracks. Use a level to help you adjust the tracks.

3. Bent Tracks

If your garage door tracks are bent, they can cause the door to gap at the top. You can fix this problem by using a hammer to straighten the tracks. Be careful when doing this, as you don’t want to damage the tracks further. Once the tracks are straight, test the door to see if the gap is gone.

4. Malfunctioning Springs

If your garage door isn’t closing properly, it might be because the springs are damaged. To fix this, you’ll need to replace them. First, disconnect the power to the door. Then, use a crescent wrench to loosen the bolts on the spring brackets. Once they’re loose, remove the brackets and old springs. Finally, install the new springs and reattach the brackets.

5. Improper Door Alignment

If your door isn’t aligned properly, it can cause it to gap at the top. This means that there is a space between the door and the frame. To fix this, you’ll need to adjust the door’s alignment.

7. Warped Door Panels

The weatherstripping around the bottom of your garage door is probably what’s wearing down and causing the gap. Purchase a new piece of weather stripping and replace it. This is an easy and affordable fix.

If the weather stripping isn’t the issue, then you may need to add Caulking to your garage door. This will help to fill in any gaps and ensure that your door is properly sealed. Caulking can be a quick and easy way to fix the problem, and it’s a solution that will last for a while.

3. Adjust Your Door

If the gap at the top of your garage door is small, you can adjust your door to fix it. First, open the door and loosen the screws or bolts on the hinges. Then, close the door and retighten the screws or bolts.

4. Add a Threshold

5. Lubricate the Tracks

Use a silicone-based lubricant to help the door open and close smoothly. Apply a small amount to the door track, and then use a soft cloth to spread the lubricant evenly. Make sure not to get any on the door itself, as it could cause it to slip off the track.

If your garage door has been used quite a bit, it might be time to lubricate the roller. This can help keep the door functioning smoothly. Apply a light coat of oil or silicone spray to the roller and pivot points.

If your garage door is hard to open or close, it might be because the spring tension is too strong or too weak.
