Black mold remediation follows the same IICRC S520 containment and removal protocol as other fungal colonization, with extra attention on identifying the moisture source that fed Stachybotrys-prone conditions. Cost tracks square footage, cavity involvement, and clearance testing more than the color of the growth..
