Floor Under Bathtub
About a week ago, I called a plumber to perform a very small fix on my upstairs toilet. He ended up busting a pipe (the supply line) and water ran into the bathroom, the master bedroom, some into the hall, and some into my son's room. Some water even leaked through the ceiling to the first floor. This plumber had a guy come out with dehumidifiers and fans to dry everything. His response time was pretty quick (about 1 hour). The fans and dehu's ran for about 48 hours.
Now, when I step into the shower, the bottom feels just a bit softer than it did before. Is it possible that water can be under the bathtub making the flooring soft or causing mold? There were some dips in the drywall ceiling on the first floor directly below the tub that have since been fixed (retaped). Also, when I step on the tiles that are right next to the tub, they creak. None of the other tiles in the bathroom creak.
I'm not very skilled with construction so any help would be much appreciated. Thanks so much...
