Plumbing disaster in Kansas City area

[Josh Coup]

The plumber that fixed our plumbing disaster (around the base of a toilet) recommended I reach out to a carpenter to check for wood-rot. The water damage is within the walls and likely the subfloor. Do I look for a carpenter like suggested or an inspector? An recommendation for either in the KC area (Overland Park)? I tore out some closet ceiling and put a fan in to circulate air and the water passed through the walls to the basement pretty quickly with no standing time.

Also, this may have been an existing issue from the previous owner. But to a lesser degree.

Thanks BP friends!
