I don’t have an answer to the question about mold.

I was involved with a couple of floods recently. A group suggested by the insurance company came in and removed sheet rock, insulation, and low level trim work and molding to expose all the saturated areas to air. They used wet vacs, put several large fans in various places pointed at the saturated areas. Carpets were lifted in areas and fans that are designed to shoot air under the carpets were inserted at about 1 or 2 per 20 x 20 area. They also used several large de-humidifiers – roughly 1 per 20x20 area. These collectively created a fair amount of heat (about 80 degrees) and these ran 24x7 for a week. You could probably get most or all of this from any reasonable sized rental company

After all was dried out, they replaced/repainted the stuff they removed.

They also used tools to detect moisture levels. They monitored moisture in several areas over time.
