Do not begin by blowing air across visible mold. EPA's flood-cleanup guidance recommends addressing visible growth before starting fans or dehumidifiers so they do not spread it. Ask the restorer how contaminated areas will be contained and cleaned before drying equipment is used, especially if water entered wall cavities or the HVAC system. Professional airflow within a controlled cleanup plan is different from a household fan circulating air through occupied rooms.
