The 1Source Remediation Process

A four-phase remediation protocol built on IICRC standards and EPA guidelines, designed to achieve certified contamination clearance on every project.

01
🔮
Environmental Assessment

Visual inspection combined with air sampling, surface sampling, and moisture testing establishes the full scope of contamination. Our assessments identify hidden mold colonies and classify sewage contamination levels to develop a precisely scoped remediation plan that addresses every affected area.

02
🛡
Containment and Protection

Negative air pressure containment chambers prevent cross-contamination to unaffected building areas while our technicians work. Personal protective equipment, air scrubbers with HEPA filtration, and decontamination protocols protect both workers and property occupants throughout the remediation process.

03
🦠
Removal and Disinfection

Contaminated materials are removed per IICRC and EPA disposal guidelines while EPA-registered antimicrobial treatments are applied to all affected surfaces. HEPA vacuum systems capture residual spore loads and the area undergoes thorough cleaning before dehumidification protocols are established to prevent recurrence.

04
🏆
Clearance Testing and Rebuild

Third-party air quality testing confirms remediation success before the containment barrier is removed. Once clearance is achieved, our remodeling division replaces all removed materials, restoring the property to pre-loss condition with fresh, contamination-free materials and complete documentation provided to property owners.

Hidden mold typically produces a persistent musty odor even in the absence of visible colonies, and may cause unexplained respiratory symptoms or allergic reactions in occupants. Water stains, peeling wallpaper, warped drywall, and discolored grout lines are visual indicators. Our thermal imaging and moisture testing equipment can detect the elevated moisture conditions that support mold growth before visible colonies develop, allowing earlier intervention at lower remediation cost.
Coverage for mold remediation depends on the underlying cause of moisture that enabled mold growth. When mold results from a covered sudden water event such as a burst pipe or roof storm damage, remediation costs are typically covered under the water damage claim. Mold resulting from long-term leaks or humidity neglect is generally excluded. Our project managers review your specific policy and document the relationship between any covered water event and resulting mold growth to support your claim.
Sewage water is classified as Category 3 black water containing a complex mixture of pathogenic bacteria including E. coli and Salmonella, viruses, parasitic organisms, and chemical contaminants. Exposure through skin contact, inhalation of aerosols, or accidental ingestion during DIY cleanup poses serious health risks. Proper remediation requires full personal protective equipment, EPA-registered disinfectants at appropriate contact times, and regulated disposal of contaminated materials, none of which are practically achievable by homeowners.
Mold cannot grow without moisture. Our remediation process addresses the contamination itself and its root cause simultaneously. Structural drying eliminates residual moisture from building assemblies, and we provide detailed moisture source recommendations, whether improving ventilation, repairing plumbing, or correcting drainage. Our remodeling team can also install moisture-resistant materials like mold-resistant drywall and vapor barriers in areas previously affected, significantly reducing recurrence risk.
Post-remediation clearance testing uses air sampling to measure airborne mold spore concentrations inside the remediated area and compare them against outdoor baseline samples and unaffected interior areas. Clearance is achieved when indoor counts are equal to or lower than outdoor levels and no elevated concentrations of the specific species that was remediated are detected. We can coordinate with independent environmental testing laboratories to provide third-party clearance documentation for your property records.
