Here's the full Onset service lineup.
Mold emergencies in Onset don't wait for business hours. When a pipe bursts, a storm floods a crawl space, or water damage creates conditions for rapid mold growth, Business Leak Detection dispatches immediately. Our emergency line for Onset is live 24/7 with real dispatchers — not voicemail, not a callback window.
HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Onset emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
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.
Commercial mold in a Onset business creates liability exposure, regulatory risk, and operational disruption simultaneously. Business Leak Detection plans every Onset commercial project around your schedule — containing affected zones without shutting down what doesn't need to be stopped.
Post-remediation verification reports are provided on every Onset commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-323-329-3586 for a Onset commercial site assessment.
If inspection finds no actionable issue in your Onset property, we tell you that honestly. We don't manufacture work that isn't needed.
Written report delivered within 24 to 48 hours of the Onset site visit. Call +1-323-329-3586 to schedule.
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 seasonal weather environment requires addressing the moisture source directly. Every Business Leak Detection 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.
Real person — 24/7 in Onset.
Certified Onset crew mobilized.

We earn these reviews by doing exactly what we said we'd do.
We were buying a home in Onset and mold showed up on the inspection report two days before closing. I called Business Leak Detection in a panic. They came out the next morning, knocked it out in 48 hours, and we had the clearance report in time for the lender. Deal closed. I've already recommended them to two friends in Onset.
I manage commercial properties in Onset and I've dealt with enough remediation contractors to know the difference. Business Leak Detection knows the protocol — contained the Onset property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Onset commercial remediation now.
Called Business Leak Detection for a Onset crawl space inspection after heavy rain flooding. They found early-stage mold before it spread, treated it, encapsulated the crawl space, and the follow-up test was clean. Catching it early saved me from a much bigger remediation cost. Should have scheduled an inspection sooner.
