We were buying a home in Walnut and mold showed up on the inspection report two days before closing. I called Zaguilan Roofing Service 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.
My Walnut restaurant was flagged for mold during a health inspection. Called Zaguilan Roofing Service 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.
Called Zaguilan Roofing Service 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.
