Onset homeowners finding mold in their home need three things immediately: a complete picture of the scope, a clear binding price, and fast professional action.

After inspection, you receive a complete written itemized estimate for your Onset project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.

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.
