There is water getting under our bathroom floor tiles. The landlord believes that due to a recent remodel of whole bathroom, water is not draining from the window ledge but is instead going into the wall and then under the floor.
I can agree with that but he swears that even though the tile has separated and continues to be wet, that because of the floor type there will not be any mold. He claims that the black I see is the glue, not mold.
He is debating whether to remove the shower etc. and wall up the bottom of the window or grout the ledge and put in a couple of holes so that water drains outside.
I'm not sure if I agree with his assessment.
What do you think?
