I recently hired someone to tile my bathroom floors. They ripped out the toilet, tiled, and then resealed the toilet. Now there is a sewage smell that has been lingering for the past few weeks. The guy came and re-sealed the toilet- no luck. There have also been 3 other plumbers that have come to check it out, but have not had any luck locating the source of the smell.
I think it's ridiculous how no one can figure out where the smell is coming from. Help please?
