crawl spaces are the film rooms of the trades. nobody wants to go in, it smells like a decision somebody made in 1987, and yet every answer about why your floor is cold is down there, on the tape, waiting. my plumber came out covered in dust and said 'it's the joist' and i nodded like a man who had been told the root cause of something. (thread. it's about joists. it's mostly about joists. (1/9))
