I bought a house that had sewer smells in the kitchen probably for years. I found the problem and fixed the pipe. We gutted the kitchen and the smell is still there. The subfloor has an odor. And I am worried the tongue and groove underneath it might smell also. If we pull up the subfloor, leave the tongue and groove, put down fresh wood for the subfloor, and then ceramic tile it, would that contain the odor? Otherwise, what are my options.
