 This is Ken Helivang, NDSU Extension Agricultural Engineer. Rebuilding a flooded home or other building starts with cleaning and drying the structure. Cross ventilate to move moist air to the outdoors. Be patient. It could take several weeks to dry. Wood should have a moisture content of less than 15% before drywall, paneling, or other coverings are replaced.
