Call Servpro. It will cost a few hundred dollars, but they will get it dried out fast and keep mold from growing. We had a few spots of mold in our house when we bought it. I fixed those myself, wearing a protective coverall and a respirator.

Since then, we have had 4 different interior floods. (1 per year). We have Servpro on speed dial. I don't want mold coming back. You have 3 to 4 days to get it dried out. If they think there is a chance it might not be dry fast enough, like when you wait 3 days before calling, they will spray mildewcide.

Fiberglass wont support mold growth but wood and drywall will. It loves the back of drywall!
