Real situations. Real Walnut customers. Real results.
We were buying a home in Walnut 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 Walnut.
I manage commercial properties in Walnut and I've dealt with enough remediation contractors to know the difference. Mold Remediation HQ knows the protocol — contained the Walnut property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Walnut commercial remediation now.
Called Mold Remediation HQ for a Walnut 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.
