We were buying a home in Portola Valley 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 Portola Valley.
My Portola Valley restaurant was flagged for mold during a health inspection. Called Business Leak Detection 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 Portola Valley basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Business Leak Detection removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
