Enter At Your Own Risk

Of course, we ran into some strange issues on this wall. Sigh. The drywall guy was late arriving so I started on it by removing a section of the wall panel. Turns out there are two layers of plywood, one on top of the other. Why that was done is beyond me. Both layers have water damage on the bottom few inches, although the outside layer facing the room is worse. The 1/4" ply that I had purchased is too thick; it would be "proud" at the seams where it will meet with wall panels at each end.

After much discussion, we decided to return the 1/4" ply and use 1/8" masonite applied on top of that inside layer, just like it was before. The local hardware store doesn't carry 1/8" ply. So I have treated the bottom of that inside layer, which will be left in place, with hydrogen peroxide. Is that mold? Some is obviously dirt. IDK, but it is easily wiped off and the peroxide will kill any mold. When we had the outside of the wall opened last summer, there was no water damage inside this wall and there is no smell of mold now so this is obviously old damage.

The major impediment is that this wall butts up to underneath large windows. If we remove that inside 3/8" layer, it may impede into the bottom of the window frame. These windows will be removed this summer, with trim being replaced, etc. and I don't want to do anything that would create a problem now in the middle of winter.

When this was my mother's house, she had that cabinet built on this south facing wall with huge windows to use for growing plants. I know my mother -- I was ready to bet money that the water damage at the bottom was a result of her careless watering. Sure enough, I spoke with my younger sister who grew up in this house and that is exactly what happened. She said when the water would spill over the top of the cabinet (because Mom didn't always use a plate under the pots), they would just mop up the floor around it. The side against the wall just stayed wet, obviously. This makes sense because the water damage was only behind the cabinet and is a perfect match to the cabinet frame. Really, Mom???
