Fully licensed for restoration and reconstruction work in Appleton, WI — credentials available on request before work begins.

We quote in writing before we start. What you approve is what you pay.
Our reputation in Appleton is one job at a time. We stand behind every single one.
Our Appleton Water Damage Restoration team handles every phase of recovery in-house: no subcontracting, no coordination gaps, no handoff problems.
Speed at this phase directly determines how much is salvageable. Our Appleton 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 Appleton 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 Appleton 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 Appleton claims is part of the service.
When drying is confirmed complete, our licensed Appleton 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.


Call +1-844-499-0972 any time — a live Appleton dispatcher answers immediately, gathers the details, and deploys the nearest crew. No voicemail, no automated queue, no call-back-tomorrow policy.
Our Appleton 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.



"Our Appleton business had a roof-to-slab water event on a Thursday night. By Friday morning COS Water Damage Restoration had extracted everything, staged drying equipment, and given me a documented scope I could hand directly to my adjuster. We were operational again the following week. Truly professional."
"I was terrified the hardwood floors in our Appleton home were gone after the flooding. The COS Water Damage Restoration crew brought in mat drying systems and dried them in place — saved us thousands versus replacement. The project manager called every morning with readings. Outstanding."
"Three companies quoted our Appleton water damage restoration. COS Water Damage Restoration was the only one who walked every room with instruments before quoting, explained each line of the estimate, and committed to the timeline in writing. They came in on time, on scope, and the claim went through without a single supplemental dispute."
