Once you’ve pulled away wet materials and established holes or cuts in the wall as needed, you’ll typically need one air mover for every 15 – 25 square feet of floor, unless the moisture load and density is particularly high, then you may need more. To prevent mold, make sure all of the layers and materials are dry before putting everything back together.
You have to open up the wall to get at the mold growing inside. Since you have to repair the wall anyway, don’t hesitate to cut the drywall back beyond the obvious damage to find all the mold and let the wall dry out. To avoid cutting electrical wires, poke a hole through the damaged section and locate the wires first. Turn off the power to the outlets before you cut. Mist the moldy drywall and insulation with the pump sprayer to avoid spreading mold spores. Double-bag moldy material in heavy-duty plastic bags and tie them shut.
In the United States, those individuals who are affected by widescale flooding may have the ability to apply for government and FEMA grants through the Individual Assistance program. On a larger level, businesses, cities, and communities can apply to the FEMA Public Assistance program for funds to assist after a large flood. For example, the city of Fond du Lac Wisconsin received $1.2 million FEMA grant after flooding in June 2008. The program allows the city to purchase the water damaged properties, demolish the structures, and turn the properties into public green space.
