Toxigenic mold species — particularly Stachybotrys — appear in Walnut properties with histories of water damage or chronic moisture. They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Walnut black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Walnut property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Prevention services for Walnut properties include crawl space encapsulation, vapor barrier installation, dehumidification system design, ventilation assessments, and structural moisture intrusion identification.

Two years of musty smell in our Walnut basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.
