How do I dry the walls of my house after flooding?

Open the wall to the level of flooding. Use a circular saw to cut sheetrock walls in a straight line, being careful not to cut into electrical wiring. If walls are paneled, remove the baseboard and pry loose the paneling. Prop paneling away from the wall, remove the insulation, and let it dry. After removing wet insulation, wash walls with disinfectant. Spray wall cavities with one cup household bleach to a gallon of water. Allow walls to stay open 4 to 6 weeks to allow thorough drying before putting in new insulation and covering.
