We were buying a home in Costa Mesa 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 Costa Mesa.
My Costa Mesa restaurant was flagged for mold during a health inspection. Called Mold Remediation HQ 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.
Two years of musty smell in our Costa Mesa 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.
