When Onalaska 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 Onalaska and surrounding WI communities with the same standard on every job — IICRC S520 protocol, written flat-rate pricing, and a satisfaction guarantee in writing.
Every Onalaska 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 Flood Damage Cleanup in Onalaska in-house. No subcontracting, no referrals, same certified standard from first call to final clearance test.
Every Onalaska emergency call gets same-day response as the operational standard. We don't send a technician to "assess and schedule" — our crews arrive with everything needed to begin containment and remediation on the first visit.
HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Onalaska emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
We find every affected area in your Onalaska home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.
After inspection, you receive a complete written itemized estimate for your Onalaska project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Onalaska area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Onalaska commercial inspection as standard.
Post-remediation verification reports are provided on every Onalaska commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-323-329-3586 for a Onalaska commercial site assessment.
If inspection finds no actionable issue in your Onalaska property, we tell you that honestly. We don't manufacture work that isn't needed.

Toxigenic mold species — particularly Stachybotrys — appear in Onalaska 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 Onalaska black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Onalaska 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 Onalaska's humidity conditions requires addressing the moisture source directly. Every Business Leak Detection project in Onalaska includes moisture source identification and documented prevention recommendations as standard deliverables.

We were buying a home in Onalaska 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 Onalaska.
I manage commercial properties in Onalaska and I've dealt with enough remediation contractors to know the difference. Business Leak Detection knows the protocol — contained the Onalaska property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Onalaska commercial remediation now.
Called Business Leak Detection for a Onalaska 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.
