"How cool," I thought. "They left the old knob and tube in the wall when they updated the electrical." The PPOs were kind of lazy, and they'd left the old sash weights in the windows, as well as unused ductwork and other oddities.
The work progressed to this:
And then this:
Oh, but do you notice something a little odd? Yep, right near the top, the old K & T is connected to a new wire that runs into the attic, servicing God-alone-knows-what.
Freaking awesome. The lazy PPOs had upgraded to a circuit breaker and a few GFCI outlets (probably not even actually grounded), but they'd obviously left at least some of the old wiring in the walls and spliced it to the new stuff. Who knows how much of this is hidden in the walls? I don't know much about electrical, but I know it's expensive, and I know that if I find something that's a code violation or safety hazard, I'm obligated to fix it. If for no other reason than if my house burns down, I want my insurance company to cover it.
Some folks find money in their walls. Other people find nifty little antiques. I find a swirling vortex of doom that magically sucks the money out of my bank account.
