COS Water Damage Restoration's Water Damage Restoration service in Mayville covers the complete recovery process — from the first emergency response through mold prevention, structural drying, and full rebuild.
The moment your call connects, our Mayville restoration dispatcher starts building your response. Extraction crews arrive with truck-mounted systems capable of removing high volumes of water rapidly — limiting saturation time and reducing the overall restoration scope.
Thermal imaging cameras and calibrated moisture meters map the full extent of water migration in your Mayville 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 Mayville 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.
We don't rebuild over hidden mold risk.
Our Mayville claim coordinators build your documentation file from day one: structured photo evidence, moisture data logs, equipment placement records, and an Xactimate scope of work that matches your carrier's estimating platform. We file, communicate with your adjuster, and follow the claim through to settlement so you don't have to.
One company, start to finish.

Our Mayville 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.

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.
