Photos Now Online ! wood rot in floor and wall

Thanks for the photos. Take a screwdriver and poke the floor in various areas. If you feel resistance, your floor is ok. What really looks to me is that it has been stained, from water, and you have black mold. Use some bleach with a brush.
My coach had the same issue- black mold.
The wall, can be done the same way- with the screwdriver. I see the wallpaper had been lifted.
Let us know what you find.
