Every affected assembly is documented with instrument readings before drying begins.
Industrial LGR dehumidifiers and high-velocity air movers are deployed in calculated configurations based on your Laguna Niguel property's materials, square footage, and psychrometric conditions. Daily readings at fixed sensor points document the drying progression until all assemblies reach target equilibrium moisture content.
Antimicrobial treatment is applied to all moisture-exposed structural surfaces as a standard preventive step in every Laguna Niguel Water Damage Restoration job. Where mold growth is identified, IICRC S520-compliant remediation — with HEPA containment, negative air pressure, and clearance testing — is performed before reconstruction begins.
Supplement filing for underpaid Laguna Niguel claims is part of the service.
One company, start to finish.
