We were buying a home in Castro Valley and mold showed up on the inspection report two days before closing. I called Mold Remediation HQ 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 Castro Valley.
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.
Two years of musty smell in our Castro Valley basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Mold Remediation HQ removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
