IICRC S520 Remediation Protocol
The IICRC S520 standard defines the professional mold remediation process: Assessment — identify mold type, extent, and moisture source. Containment — seal the work area with poly sheeting and establish negative air pressure. Air filtration — run HEPA air scrubbers throughout remediation. Removal — carefully remove contaminated materials per protocol. Cleaning — HEPA vacuum and antimicrobial treatment of all remaining surfaces. Verification — post-remediation testing confirms successful remediation.
Containment: The Most Critical Step
Proper containment separates mold remediation from amateur mold removal. Without containment, removing mold-contaminated drywall releases millions of spores into the air — potentially contaminating the entire home. Our containment setup uses 6-mil polyethylene sheeting with sealed seams, negative air pressure (maintained by HEPA-filtered air scrubbers exhausting to the exterior), and decontamination chambers for worker entry/exit.
Addressing the Moisture Source
Mold remediation without addressing the moisture source is incomplete — mold will return. Common moisture sources in Mesa include plumbing leaks (especially slab leaks), AC condensation overflow, monsoon roof leaks, bathroom ventilation inadequacy, and slab moisture vapor transmission. We identify and resolve the moisture source as part of every remediation project.
Residential Mold Remediation in Mesa
Residential mold remediation must balance thoroughness with livability. For small, well-contained projects, most families can stay home during remediation — containment barriers seal the work zone from living spaces. For larger projects or homes with immunocompromised residents, we may recommend temporary relocation. We communicate clearly about what to expect and provide daily progress updates.
Commercial Mold Remediation in Mesa
Commercial mold remediation in offices, retail, and healthcare facilities requires minimal disruption to operations. We offer after-hours and weekend scheduling, develop phased remediation plans for large facilities, and provide documentation that satisfies landlord-tenant, OSHA, and insurance requirements. For healthcare facilities, we follow enhanced protocols that meet infection control standards.
