COS Water Damage Restoration's Water Damage Restoration service in Sun Prairie covers the complete recovery process — from the first emergency response through mold prevention, structural drying, and full rebuild.
The moment your call connects, our Sun Prairie 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 Sun Prairie 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 Sun Prairie 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.
Supplement filing for underpaid Sun Prairie claims is part of the service.
One company, start to finish.

No work starts without your written approval of the scope and cost.
Written satisfaction guarantee on every Sun Prairie job.
