Wow, you guys are pretty great at predicting all the problems we'll have!
We got all the biggest stuff up this weekend, and the worst spot is under the fridge...there is some rotting (as eclecticcottage predicted! see photo)...but its not all the way through and still pretty solid....and will continue to be under the fridge. Perhaps we will replace a few boards...would only be 2-4 boards. The entire area was a little "mildew-y", but just the surface.
We also found one small hole in the middle of the floor. See photo.
The ceramic tile under the middle section did end after the arch...which was nice, but I am very sore today (and my husband's sorer), the plywood was nailed and glued down...so it didn't want to come up.
Lots of "edging" left to get up, and we'll see how sanding goes...there was one other spot where there was a "chunk" out of the wood...so still kind of leaning towards patching and painting...to be continued....
