From species confirmation to IH-supervised clearance — the complete protocol for black mold in Tualatin properties.
Identification
🔍Species Confirmation via Lab Analysis
Dark coloring alone does not confirm Stachybotrys. Multiple mold species produce dark or black-appearing growth — Cladosporium, Aspergillus niger, Aureobasidium. Surface swab or tape lift samples sent to an accredited lab confirm the species before we apply the enhanced Stachybotrys protocol. Correct identification matters because it determines the containment tier, PPE level, and disposal approach.
Containment
🔥Type III Containment Establishment
Type III containment means double-layer 6-mil poly barriers floor-to-ceiling, HEPA negative air machines creating inward airflow verified by smoke pencil, sealed HVAC registers, and sticky mat decontamination stations at every containment entry. Established in full before any Stachybotrys-contaminated material is disturbed in your Tualatin property — no exceptions.
Removal
🔨Complete Contaminated Material Removal
All Stachybotrys-contaminated porous materials — drywall, insulation, carpet, ceiling tile, wood materials with surface penetration — are removed completely, double-bagged in heavy-duty poly, and disposed of through documented waste channels. No partial removal, no material left in place and treated in situ.
Treatment
💧Structural Surface Treatment & Encapsulation
HEPA vacuum, EPA fungicide, encapsulant — all remaining structural surfaces after material removal. Chemical treatment plus physical barrier as the standard, not the upgrade.
Drying
💨Moisture Source Identification & Correction
Stachybotrys only establishes on material that has been consistently wet for an extended period. Its presence confirms a sustained moisture source — plumbing leak, roof infiltration, chronic condensation, or ground moisture intrusion. We identify and document the source and provide specific corrective recommendations, because removal without source correction produces recurrence within months.
Clearance
✅IH-Supervised Post-Removal Clearance
Independent IH, not the remediation contractor, collects and interprets post-clearance samples. Written IH clearance report confirms the Stachybotrys removal achieved its objective.
