As winter approaches the cold tile floor of the Generals kitchen announced a draft create by a gap under the back door.  After browsing some expensive options to remedy this situation, I realized that a three foot piece of base board I purchased at the Habitat for Humanity ReStore would serve the same purpose  in raising the floor and closing the gap.  I removed four screws from the old piece of aluminum shown in the first image, cut the base board to size and added five new screw.  The door now closes firmly, and no draft causes the tile to be so unbearably cold on my feet in the morning.
