1. Second tetanus shot run of the project (Sorry about that, Bob).
2. One $300, two-week-old nail gun jammed. Still under warranty but must go back to the manufacturer for repair.
3. 18 empty cans of high-expansion spray foam. It turns out that the stone facade on the front of our house is a) not actually siding and b) not properly installed.
Let me elaborate on that a bit.

The stone in the picture above appears to be some sort of siding attached to the house, right?
Wrong.
That isn’t siding. That’s landscaping rock that was built into a thin wall in front of the house and attached with a line of caulk. Also, there is nothing behind it–no mortar or anything. Well, there wasn’t originally. By the time we discovered this amazing fact, there were bees’ and mud-dauber wasps’ nests in that space…probably at the maximum density preferred by bees and mud-dauber wasps.
So now I at least know why that wall was always so cold on the inside of the house, and where all the bees and wasps were coming from. We sprayed the area quite thoroughly, but survivors kept straggling in over the weekend. By Sunday afternoon, I found myself yelling at them “Your home is gone and everyone’s dead! Go daub your mud somewhere else!”
At least the nests left something for the 18 cans’ worth of high-expansion spray foam to affix to.
And, at least that wall was basically intact.
Not so much the wall pictured below.

An attempt to remove the trim along the dividing line between the wood and the stone resulted in this:

And another five minutes of crowbar work and swearing later, the entire stone wall was down…except for about three large pieces at the bottom that had been cemented in place. That required some serious maul work from Spouse (and more cursing of our builder and his orangutans). We’re planning to side over that bit of the garage, not in the least because Lowe’s is probably out of high-expansion spray foam for some reason. And we’ll reuse the landscaping rock in some sort of landscaping feature. No idea what, but it’s quite nice sandstone that won’t fit in the dumpster even if I felt like moving it, which I don’t.
On the positive side, we now have half of the new windows in—did I mention that the windows in the front of the house weren’t even nailed into place? They were held in by the trim— and most of the siding is down, thanks to Spouse, Bob, and Phil. There’s a bit of siding left on the east side of the house and the garage, and that’s all. Except for the little bits of siding trapped against the side of the house by the front door, because the concrete steps were poured right up against the house with no spacers.
sigh
On the other hand, fifteen minutes with a razor knife to trim the extra bits of house wrap, and the west side of the house is ready for siding, as is the entire back, except for the chimney, which wants only house wrap as well. Half of the front is also ready for siding, and most of what’s left only needs the oriented-strand board base and wrap put up.
I hope the rest of the siding gets delivered this week. Not to mention the bay window, which we had to special order.
