Market Intelligence & Technical Specifications
In Gresham, our mold remediation methodology is a precise application of environmental science and building pathology, fully aligned with the IICRC S520 standard and local Multnomah County health regulations. Each project begins with a comprehensive environmental assessment, utilizing moisture meters, thermal imaging cameras, and, when necessary, air and surface sampling to define the extent of fungal proliferation (Condition 2 or 3). Our containment strategy involves multi-layer critical barriers and the establishment of negative air pressure using high-velocity air filtration devices (AFDs) with medical-grade HEPA filters. This containment protocol is non-negotiable and prevents the aerosolization and migration of spores to unaffected areas of the structure. Remediation of contaminated building materials is executed with surgical precision. Porous materials like insulation and gypsum board are methodically removed, double-bagged in 6-mil polyurethane, and disposed of according to Gresham's solid waste guidelines. For semi-porous substrates, such as concrete and wood framing, we employ a combination of mechanical abrasion—wire brushing, sanding, or media blasting—and HEPA vacuuming to physically remove fungal structures. Following physical removal, we apply an EPA-registered, broad-spectrum disinfectant and fungicidal coating to eradicate any remaining spores and inhibit future growth. Our HVAC decontamination process is equally rigorous, involving a full system cleaning to remove mold from ductwork and air handlers, ensuring the system does not act as a distribution network for contaminants. Post-remediation verification is the final, critical step. We mandate independent, third-party clearance testing to confirm that the indoor fungal ecology has been returned to a normal state (Condition 1), ensuring the health and safety of occupants and providing unimpeachable documentation of a successful project.
