Habemus plus vis computatoris quam Deus

After tearing out the rest of the rotten wood from the entryway, we've found that the rot goes under the corner of Pirate's floor, and that there is improperly repaired water damage all across the front of the house at the foundation line. When they repaired it before, they did not go all the way across the front of the house, they did a poor job of the repairs they did, and they used the wrong materials.  The facing board at the bottom of the wall was just low-quality strand board, not even exterior grade, the new stucco they put over the top of it was poorly applied, and the cement cap they put on top of the foundation wall doesn't seal properly to the stucco.  A third of the sill plate is rotted out, and most of the floor joists have rot in the outer ends.  (Fortunately, the rot mostly does not extend beyond the sill plate, or the house would be subsiding on that side.)

This is going to be an even bigger and more expensive repair job than we previously thought.
