The claims adjuster says they can only cover floor replacemnt in the master bathroom as there is a door between the bath and the room.

At yet another sale there was a brick row house/town house for sale that looked good from the street, but since it was in the middle of the row, to see the back of the house, you had to walk around the block and see the house from the alley, where the entire 3 story brick back wall of the house was laying in the back yard, and there was no back wall standing.
