Mold spores can move beyond the room where the original growth started, especially through airflow, HVAC systems, or when contaminated materials are disturbed. But spores landing in another room does not automatically mean mold will start growing there. Moisture is the bigger piece of the puzzle. If another area is dry, mold has a much harder time establishing itself. If there is also humidity, a leak, or another source of moisture, that is when a second problem can develop. If you are concerned mold may be affecting more than one area of your home, AmeriDri can help you figure out what needs attention at ameridri.com.
