Walnut homeowners finding mold in their home need three things immediately: a complete picture of the scope, a clear binding price, and fast professional action. Zaguilan Roofing Service delivers all three — thermal imaging, air sampling, written estimate, and IICRC S520 protocol from the first inspection through final air clearance testing.
After inspection, you receive a complete written itemized estimate for your Walnut project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
