It's a mad dash before winter sets in!
The old "deck" was very rickety, and over the last few months, a couple of the stairs actually broke through, to the point we were only walking on the stair supports. Now, though it isn't quite done, we actually have a large deck, which is very useful as a workspace if nothing else!
The dining room ceiling was caving in, so we jacked it up, and installed extra support beams in the attic, so now there is only a small sag, which won't be noticeable once we get the drywall up!
The basement had serious moisture issues. There was mold on the walls, and the concrete floor was actually completely buckled - no huge shock, seeing as it was only 1/2" thick! We tore out all the concrete, installed drain tile (which is already functioning well!), and poured new concrete. It's a whole new basement!
We tore out the chimney, so created a hole in the roof. There were also many roof boards that needed to be replaced, so we fixed that all up before we put new shingles on.
