Toxigenic mold species — particularly Stachybotrys — appear in Duarte 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 Duarte black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
If you suspect black mold in your Duarte property, call +1-323-329-3586 immediately. Don't disturb the area — let certified technicians handle it safely.
