Mold grows fast in CA — heat and humidity let Aspergillus, Penicillium, and Stachybotrys colonize within 48-72 hours after water exposure. If you see or smell mold in your San Francisco property, it's established and needs professional remediation. Bleach only bleaches the surface while roots keep growing behind the wall.
Our Mold Remediation Process
Assessment & Testing
Visual inspection plus moisture mapping identifies the scope. We recommend a third-party air test before remediation starts — independent testing keeps the process honest.
Seal & Contain
We build a sealed containment zone with 6-mil poly sheeting and run negative air machines. HEPA air scrubbers filter the air inside containment. Spores stay contained — they don't spread.
Removal & Treatment
We cut out affected drywall, insulation, and other materials safely. Structural wood and concrete get antimicrobial treatment. Everything is done inside containment with HEPA filtration running.
Clearance Testing
Third-party air testing confirms remediation was successful. We don't release containment until clearance testing passes. Your results come from an independent lab, not from us.

About Our San Francisco Mold Remediation Services
We follow IICRC S520 and ANSI/IICRC R520 standards on every mold job in San Francisco. Documented containment, HEPA filtration, controlled removal, approved antimicrobials, and post-remediation clearance testing by an independent hygienist — not by us. Hiring one company for testing and removal is a conflict of interest.
