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