Found black mold in our Castro Valley home after a hidden plumbing leak. Called Mold Remediation HQ at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Castro Valley 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.
I manage commercial properties in Castro Valley and I've dealt with enough remediation contractors to know the difference. Mold Remediation HQ knows the protocol — contained the Castro Valley property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Castro Valley commercial remediation now.
Called Mold Remediation HQ for a Castro Valley 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.
