From initial assessment to independent clearance — full black mold protocol in Mercer Island, WA.
🔍
Black Mold Identification & Assessment
Confirmed black mold removal starts with identification. Our Mercer Island, WA technicians collect surface swab samples from suspected areas and can have lab results confirming species within 24–48 hours. We don't assume Stachybotrys based on color — we confirm it, because the remediation protocol is different from standard mold removal and misidentification wastes your money.
😷
Full PPE & Containment Setup
Full body PPE, double polyethylene containment, negative air pressure, and sticky mat decon — this is the setup before a single piece of black-mold-contaminated material is disturbed in your Mercer Island, WA property.
🔨
Complete Stachybotrys Material Removal
Stachybotrys on drywall, ceiling tiles, or subflooring means those materials must be removed — not treated in place. The mycotoxin-containing material itself is the hazard, and surface biocides don't render it safe or remove it from your Mercer Island property. We remove contaminated materials, bag them in heavy-duty poly, and dispose of them through proper waste channels.
💧
Structural Surface Treatment & Encapsulation
Post-removal structural treatment: HEPA vacuum of framing surfaces, EPA fungicide application, and encapsulant sealing of treated wood. The most thorough protocol available for Mercer Island properties with confirmed black mold.
📋
Independent Post-Removal Air Testing
After Black Mold Removal in any Mercer Island, WA property, an independent industrial hygienist collects post-removal air samples and sends them to an accredited lab. We will not declare a job complete without objective third-party confirmation that Stachybotrys spore counts have returned to acceptable levels.
🏗
Moisture Source Identification & Correction
Stachybotrys only grows on consistently wet cellulosic material. Its presence means there's been a sustained moisture source — typically a leaking pipe, roof infiltration, or chronic condensation issue. We identify and document the moisture source on every Mercer Island, WA black mold job and provide specific corrective recommendations, because removal without source correction means regrowth.
