When Ontario homeowners and business operators deal with mold, they need a company that knows the area, shows up fast, and gives them a binding written price before touching anything. That's Business Leak Detection. Our certified crews serve Ontario and surrounding CA communities with the same standard on every job — IICRC S520 protocol, written flat-rate pricing, and a satisfaction guarantee in writing.
Every Ontario project starts the same way: a live person answers when you call, certified crew dispatched fast, thorough inspection with documented findings, written estimate you sign before work starts, and a job that closes only when post-clearance air testing confirms success.
We handle every phase of Sewage Backup Cleanup in Ontario in-house. No subcontracting, no referrals, same certified standard from first call to final clearance test.
Mold emergencies in Ontario 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 Ontario is live 24/7 with real dispatchers — not voicemail, not a callback window.
HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Ontario emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
Ontario 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 Ontario project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.

We were buying a home in Ontario 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 Ontario.
My Ontario restaurant was flagged for mold during a health inspection. Called Business Leak Detection that morning. Crew on-site by noon, affected prep area contained without shutting down the full kitchen, clean clearance report before my reinspection. Saved us from a week-long closure. They understood exactly what was at stake.
Called Business Leak Detection for a Ontario 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.

Standard homeowners insurance in Ontario typically covers mold remediation resulting from a covered sudden event — burst pipe, storm damage, appliance failure. Mold from gradual neglect is generally excluded under CA policies. Business Leak Detection provides complete documentation packages structured for Ontario insurance carrier submission: inspection reports, certified lab analysis, photo documentation, remediation scope, and clearance reports. We communicate with your Ontario adjuster directly when that helps the process.
Mold recurrence in Ontario properties almost always traces to an unresolved moisture source — not to failed remediation work. We address this directly by identifying and documenting the cause on every project. Call +1-323-329-3586 to learn more about our Ontario prevention services.
