2. Next, check the weather stripping around the edges of the door. If it is worn or broken, replace it with new weather stripping. This will help to keep drafts from coming through the door.

3. Finally, add a layer of insulation to the inside of the door. This will help to keep the garage warm in the winter and cool in the summer.
