Removal, cleaning and product contact time
Contaminated porous materials are removed rather than dried in place. The cut boundary extends above the visible waterline to address measured wicking and affected material. Carpet pad, saturated insulation and contaminated drywall can retain sewage beyond the surface that appears dirty. Extraction removes accessible liquid, followed by controlled removal and cleaning of suitable remaining structural surfaces.
At properties around Carleen Bright Arboretum, the crew plans the contaminated-work boundary around the inspected room. An EPA-registered antimicrobial may be used on suitable cleaned surfaces according to its label, including the required dwell time. Spraying over debris does not replace physical cleaning or removal. The team documents those stages before airflow begins.
- Separate cleaned equipment and tools from dirty handling zones.
- Bag or contain removed porous materials through the disposal route.
- Keep treatment products on the intended surfaces for their specified contact time.
- Begin drying only after the remaining assembly is prepared for it.
