Professional Mold Remediation in Portland

Our mold remediation protocol strictly adheres to the IICRC S520 Standard for Professional Mold Remediation, serving as the cornerstone of our operations in Portland, Oregon. Initial assessment involves a comprehensive site evaluation using thermal imaging cameras, like the FLIR E8, and digital hygrometers to map moisture intrusion pathways and affected substrates. Containment is established using 6-mil polyethylene sheeting to create isolated negative pressure zones, employing commercial-grade air filtration devices (AFDs) such as the Dri-Eaz DefendAir HEPA 500, which operates at a minimum of 4 air changes per hour (ACH). Source removal of contaminated porous materials is executed with precision, followed by HEPA-sandwiching techniques on remaining structural elements. All technicians are equipped with full personal protective equipment (PPE) compliant with OSHA 29 CFR 1910.134. We utilize EPA-registered, hospital-grade fungicidal disinfectants and antimicrobial coatings to treat surfaces post-remediation. Final clearance is contingent upon passing a third-party, post-remediation verification (PRV) inspection, including non-viable spore trap analysis (e.g., Air-O-Cell cassettes) evaluated against outdoor ambient levels, ensuring we meet or exceed all local Multnomah County and Oregon Health Authority (OHA) guidelines for indoor air quality and habitability.
