Toxigenic mold species — particularly Stachybotrys — appear in Onset 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 Onset black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Onset property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Remediation removes the active colony. Prevention keeps it from coming back — which in Onset's climate requires addressing the moisture source directly. Every Mold Remediation HQ project in Onset includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Onset customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.
