Mold remediation is the process of finding, containing, and removing mold from an affected area and the air around it. It’s crucial to contain it to one area because spores are microscopic and can easily spread to other areas through the air or by attaching themselves to clothes or objects. Mold remediation experts usually use air pressure and physical barriers to seal off the infected area, including ductwork. Sophisticated filters clean the trapped air before it gets into the building’s ventilation system.
