What is Condition 3 in mold remediation?
Condition 3 is an indoor environment with actual mold growth and associated spores. Growth may be visible or hidden inside wall cavities, HVAC systems, or beneath flooring. Remediation requires physical removal of the contaminated material — not just cleaning or encapsulation. Per IICRC S520 §12.
