Four reasons Knapp homeowners and businesses call COS Water Damage Restoration first when water damage strikes — and give us five stars when we're done.
Every technician holds active WI contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Knapp job.
Locally staged equipment and crews mean our Knapp response time beats out-of-area contractors every time.
We quote in writing before we start. What you approve is what you pay.
Our reputation in Knapp is one job at a time. We stand behind every single one.
Our Knapp Water Damage Restoration team handles every phase of recovery in-house: no subcontracting, no coordination gaps, no handoff problems.
The moment your call connects, our Knapp 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.
Every affected assembly is documented with instrument readings before drying begins.
Drying isn't complete until the numbers confirm it — not when a certain number of days have passed.
Antimicrobial treatment is applied to all moisture-exposed structural surfaces as a standard preventive step in every Knapp 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.
Our Knapp 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.


Call +1-844-499-0972 any time — a live Knapp dispatcher answers immediately, gathers the details, and deploys the nearest crew. No voicemail, no automated queue, no call-back-tomorrow policy.
Local crews mean local speed — we know Knapp's roads and we move fast.
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.
