My second floor bathroom toilet overflowed and water ran under the tile floor. The previous homeowner did a DIY tile job over the existing linoleum and didn’t put any kind of sealant in the gap between the tile and the wall behind the toilet, so whenever there’s water from the toilet or shower it can get into the wall and under the floor. Pics with baseboard removed.
I haven’t seen any evidence of water damage in the downstairs ceiling, but there are some internal walls in the way so I’m worried it might just be hidden. I’ve owned the house for 2 years and lots of splashes from the tub.
How screwed am I?
