How to Replace Garage Door Seal?

Replacing the seal on your garage door is a relatively straightforward process that can help keep moisture and pests out of your garage. If you’re unsure about how to go about replacing the seal, this guide is here to help. After reading through the steps below, you’ll be well on your way to having a properly sealed garage door in no time. So let’s get started!


First, it’s important to identify exactly what kind of seal needs replacing on your garage door. If the weatherstripping or seal is old and worn out, it’s time to replace it. You can usually tell by looking for gaps around the edges of your garage door. If you don’t have any visible cracks or gaps, then there’s no need to replace the seal yet.

Once you’ve identified that a seal needs replacing, you’ll need to make sure that you have the right supplies. You will need a new weather seal, some screws, and either a drill or screwdriver. Make sure that your new seal is the same size as the old one, so it fits correctly on your garage door.

Next, remove any trim around the edges of your garage door. This will allow you to access the screws that hold the seal in place. Once you’ve removed the trim, unscrew any screws holding the old seal in place and carefully remove them from your garage door.

Once you have the old seal off, it’s time to install the new one. Start by aligning your new weather seal with the edge of your garage door, and then use the screws to secure it in place. Make sure that you are careful not to over-tighten them, or you may damage the seal.

When all of the screws have been tightened and the new seal is securely in place, you’re done! Take a step back and admire your work. You’ve just successfully replaced the seal on your garage door and can now rest assured that you’ll have a better seal against any moisture or pests.
