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. Business Leak Detection delivers all three — thermal imaging, air sampling, written estimate, and IICRC S520 protocol from the first inspection through final air clearance testing.
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.

Found black mold in our Onset home after a hidden plumbing leak. Called Business Leak Detection at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Onset property the next morning with a written estimate before they looked at anything. Done in 48 hours, air clearance test passed, price matched exactly what they quoted. That's exactly how it should work.

Two years of musty smell in our Onset basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Business Leak Detection removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
