That's concerning to hear.
We have some black spots in the bottom edge of caulking in our shower. I've always thought it was just a shoddy caulking job or product and not caused by water behind the tile itself.
If I remove the caulking, any way to know if the water is behind things without ripping tiles off?
The house is less than 10 years old - anyone know if is this a home warranty thing possibly?
