COS Water Damage Restoration's Water Damage Restoration service in Delavan covers the complete recovery process — from the first emergency response through mold prevention, structural drying, and full rebuild.
Speed at this phase directly determines how much is salvageable. Our Delavan crews don't slow down on the way to your property.
Thermal imaging cameras and calibrated moisture meters map the full extent of water migration in your Delavan property — identifying affected wall cavities, subfloor assemblies, and ceiling materials that aren't visible on the surface. A complete damage picture drives a more accurate scope and a faster insurance claim.
Industrial LGR dehumidifiers and high-velocity air movers are deployed in calculated configurations based on your Delavan 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 Delavan 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 Delavan claims is part of the service.
When drying is confirmed complete, our licensed Delavan reconstruction team handles all rebuild work — drywall, flooring, painting, trim, structural framing — under the same project manager who ran the restoration phase. No handoff to an unknown subcontractor, no coordination gap, no restart of the communication process.


Real person, real dispatch. Call +1-844-499-0972 and your Delavan crew is moving before you hang up.
Our Delavan crew targets on-site arrival in 60 minutes or less, staging extraction equipment and containment supplies during transit so they're productive the moment they arrive.
No work starts without your written approval of the scope and cost.
Extraction, drying, remediation, and reconstruction proceed under daily monitoring and documented progress reporting. The job isn't complete until final moisture readings confirm success and you've conducted the walkthrough with your project manager.
