      Begin this process by removing the hinge pins from the hinges and removing the door from its place.

      We recommend placing the door on a flat surface covered by a blanket or some other barrier to help protect your door from damage.

       

      Step 2) Remove existing door bottom

      Using the putty knife, pry the door bottom away from the door. Be sure to remove any leftover staples from the door.

       

      Step 3) Clean bottom of door slab

      Scrape the bottom edge of the door with the putty knife, removing any excess caulk or stubborn staples from the door.

       

      Step 4) Apply sealant to the new door bottom

      Apply sealant to both ends of the door bottom in the pattern shown above.
