The second story of the chimney in the front room had already been removed (in the 60's judging by the artifacts found in the shaft), we built temporary walls to support the ceiling joists and took it out the rest of the way, brick by brick, piled it in the backyard for use in sidewalks.
We loaded new lumber in and began to install it in the termite-eaten areas - we are starting with the front of the house and moving backwards. In order to fix the front wall and then sheath it with plywood, we removed all the doors, windows, trim and siding.
