Testing for airborne and surface mold is essential after any remediation efforts, whether due to flooding or fire incidents, to ensure no concerning spores remain. Following flood responses, and particularly after wildfire events where ash and smoke residues could be present, it’s vital to implement bi-polar ionization either through integrated HVAC systems or portable units. This technology helps prevent the spread of spores to unaffected areas while also protecting individuals from inhaling them. Additionally, it is essential to create containment zones in areas undergoing flooding recovery and mold remediation to stop spores from dispersing throughout the environment. Use plastic barriers to seal off these areas and ensure that air is exhausted to the outside.

In the wake of flooding or fire damage, any wet drywall should be removed and replaced. If there is uncertainty about the condition of the drywall, an Indoor Air Quality (IAQ) professional can utilize a moisture meter to assess its status. For wooden structural elements such as studs or floor joists that have been exposed to moisture, they should be thoroughly cleaned with an EPA-certified anti-microbial cleaner and then sealed with a primer to prevent mold growth. Concrete floors, likewise, should be treated with an EPA-certified anti-microbial cleaner to ensure a thorough recovery from contamination and maintain a safe indoor environment.
