IICRC S520-compliant removal across every scenario — surface colonies, cavity infestations, post-water-event growth, HVAC contamination.
Category Assessment
📋Water Category Classification & Protocol Selection
IICRC S520 links mold removal protocol to the water category that caused the moisture — Category 1 (clean), Category 2 (grey), or Category 3 (black/sewage). A Category 3 event requires full PPE escalation and enhanced containment that isn't needed for Category 1. Our Marysville, MI crews classify the source before selecting the removal protocol.
Containment
🔥Negative Air Containment Setup
Physical containment is established before any material removal — 6-mil poly barriers, zipper entries, HEPA negative air machines creating inward airflow, and sealed HVAC registers. Spore migration during removal is prevented, not managed after the fact.
Extraction
🔨Contaminated Material Removal
Physical removal of all contaminated porous materials from your Marysville, MI property — properly bagged and disposed. Remaining surfaces HEPA-vacuumed before biocide application.
Treatment
💧EPA Biocide Application
EPA-registered biocide application on all remaining structural surfaces after extraction — category-appropriate product selection, documented application, and optional encapsulant for salvageable framing.
Drying
💨Structural Drying Where Needed
When residual moisture remains in structural materials after removal, we deploy desiccant or refrigerant dehumidifiers and air movers — logging daily psychrometric readings against IICRC drying targets until materials reach equilibrium moisture content.
Clearance
📄Independent Post-Removal Air Sampling
An independent industrial hygienist collects post-removal air samples from the treated zone and outdoor comparative samples — processed by an accredited laboratory. You receive a written clearance report, not just a contractor's assurance the job is done.
