Once you have your sealant, simply apply it to the gap on either side of your door. You’ll want to make sure that you smooth it out as much as possible so that there are no air bubbles. Once it’s dry, you can add a second layer if you want to be extra sure that the gap is sealed.

If you’re not interested in using a sealant, another option is to use caulk. Caulk is a slightly different material than sealant, but it’s still effective at filling gaps. You can find caulk in a variety of colors, so you can choose the one that best matches your garage door.

Once you’ve applied the caulk or sealant, you should add a layer of weatherstripping to the sides of your door. This will help to further seal the gap and prevent any air or moisture from coming in.

Adding weatherstripping is a simple process, and it’s one that you can do yourself. First, measure the length of the gap on either side of your door. Then, cut the weatherstripping to size using a utility knife. Next, peel off the backing and apply the weatherstripping to the sides of your door. Finally, use a hammer or screwdriver to nail or screw the weatherstripping into place.




Once you’ve added the sealant, caulk, or weatherstripping, your door should be better sealed against the elements. This will help to keep your garage cooler in the summer and warmer in the winter, which can save you money on your energy bills. It can also help to prevent moisture and pests from entering your garage.

How to Fix Gap On One Side Of Garage Door

If you want to fix the gap on one side of your garage door, you can use a sealant. You can either use a silicone-based sealant or a latex-based sealant. If you’re using a silicone-based sealant, make sure that it’s compatible with the material of your garage door.

To apply the sealant, first, clean the area around the gap with a degreaser or soap and water. Then, apply the sealant to the gap using a caulking gun. Smooth it out with your finger and allow it to dry for 24 hours before opening or closing the door.




If you’re using a latex-based sealant, you can apply it in the same way as the silicone-based sealant. However, you’ll need to wait longer for it to dry – at least 48 hours.

Once the sealant has dried, you can close the door and test it to see if the gap has been filled. If the gap is still there, you may need to apply a second coat of sealant.

How to Fill Garage Door Gaps

The first step is to determine the size of the gap. Once you know how wide the gap is, you can select the appropriate size of sealant. You will also need a putty knife and something to clean the surface with, like a rag.

If the gap is wider than 1/4 inch, you will need to use caulk. If the gap is 1/4 inch or less, you can use weatherstripping.

1. To caulk the gap, apply a bead of caulk around the perimeter of the door.

2. Use the putty knife to spread the caulk evenly over the surface.

3. Wipe away any excess with the rag.

4. To weatherstrip the door, cut a piece of weatherstripping to the appropriate size.

5. Peel off the adhesive backing and apply the weatherstripping to the door.

6. Press it into place and make sure that it is secure.

If you have a gap on one side of your garage door, you can fix it by filling it with sealant or weatherstripping. Make sure to select the right type of material based on the size of the gap, and follow the instructions carefully so that you get a good seal.

So, if you have the question, how do I fill the gap between my garage door and wall? You have the answer! Be sure to fix that gap as soon as possible so that your garage door is weatherproof and energy-efficient.
