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.

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.
