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