The new tile, including installation, will be covered under the insurance. They will
not make an attempt to save the old tile - takes too much time and careful work.
They'll just bust it up and get it out. Then the floor can dry and the mold can be
tackled. The mold in the walls will go out with the sheetrock. There may be mold on
the back of some of the kitchen cabinets, but hopefully it can be cleaned off once
the cabinets are removed.

That is what the mold spray is for. It will knock down the mold but it
usually has a dye in it so you can't use it on exposed materials
When my wife had the "mold guy" in they sprayed trusses, studs and
affected block. You should get a certificate when he is done that says
everything is OK. That might be important when the house is sold.
