The Minnesota Department of Health wants to make sure that residents whose homes flooded recently get cleaned up right away, to avert any health related consequences of mold exposure.
Dry it up ASAP. That will help avert damage. When you think it’s dry, you might check around for a mold inspector with specialized equipment to search for hot spots.
Depending on what your mold inspector suggests, you may have to rebuild or retrofit with water-resistant construction materials.
Once you get it dry, keep it dry. If it takes dehumidifiers, a new roof, or regrading of your property to channel water safely away, it is worth the expense to keep your property safe from water intrusion. Water intrusion=mold intrusion.
