Set up shop out there, to work on the house floor. Finally.
Got the first subfloor board screwed and glued. Got the under house crossover hooked up and spread some goop over it. And a register crudely cut in, for at least SOME airflow/ heat in this part of the house.
Only the one in the corner is glued/screwed. It’s midnight, and I have work to wake up for around 4 am. But tomorrow after work, I can glue and screw the others. Start getting this house back to livable condition. I have some more work to do underneath, but I’m hopeful I can at least get the living room buttoned up and ready for winter
