There are many factors that impact the amount of time needed to effectively dry all affected property and materials. As per the IICRC-S500, the industry standard for water remediation practices, the “dry-standard” is reached when the moisture content of affected materials returns to a level within 10% of moisture content prior to a water intrusion. Meaning, materials are dry when their moisture level matches the rest of your home or business prior to any water damage, and is at least below the 16% moisture level. 16% is the threshold that marks the onset of mold growth.
