Speed at this phase directly determines how much is salvageable. Our Mount Desert crews don't slow down on the way to your property.

Where mold growth is identified, IICRC S520-compliant remediation — with HEPA containment, negative air pressure, and clearance testing — is performed before reconstruction begins.
