  • Mark using a marker on the weatherstrip.
  • Use scissors to cut the foam area only to use on the top, bottom, and side of the door jamb.
  • Then, grab a chopping saw to get the desired size wood flange.
  • After that, attach the nails to all pieces of the flange to position them better. During the course, try to seal them lightly. And then, inspect if any changes are needed or not.
