IICRC S520-compliant removal across every scenario — surface colonies, cavity infestations, post-water-event growth, HVAC contamination.
Category Assessment
📋Water Category Classification & Protocol Selection
Water source classification determines PPE requirements, containment tier, and disposal protocol on every Gladstone mold job. We assess and document the water category before work begins.
Containment
🔥Negative Air Containment Setup
Containment before removal, always. Poly barriers, HEPA negative air, sealed registers — established before any contaminated material is disturbed in your Gladstone property.
Extraction
🔨Contaminated Material Removal
Physical removal of all contaminated porous materials from your Gladstone, OR property — properly bagged and disposed. Remaining surfaces HEPA-vacuumed before biocide application.
Treatment
💧EPA Biocide Application
After physical extraction, remaining structural surfaces are treated with EPA-registered antimicrobial agents rated for the contamination category. For Category 3 events, enhanced disinfectants are used. Encapsulant is applied to salvageable structural wood where warranted.
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.
