Here's what separates COS Water Damage Restoration's Water Damage Restoration service from every other option in Nunda.
Fully licensed for restoration and reconstruction work in Nunda, SD — credentials available on request before work begins.
Locally staged equipment and crews mean our Nunda response time beats out-of-area contractors every time.
We quote in writing before we start. What you approve is what you pay.
Every Water Damage Restoration job in Nunda carries our written satisfaction guarantee. If the result doesn't meet the documented standard, we return and make it right at zero additional cost.
Our Nunda 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 Nunda crews don't slow down on the way to your property.
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 Nunda 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 Nunda claims is part of the service.
One company, start to finish.


Real person, real dispatch. Call +1-844-499-0972 and your Nunda crew is moving before you hang up.
Our Nunda 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.
A thorough walk-through with moisture instruments and thermal imaging establishes the full scope of loss. You receive a written, itemized Xactimate estimate before any work begins — signed off by you before the first tool is placed.
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 Nunda 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."
"The insurance side of a water damage claim is overwhelming. COS Water Damage Restoration's Nunda team handled everything — filed the first notice, attended the adjuster visit, and got us a fair settlement. I didn't make a single insurance phone call myself."
"Three companies quoted our Nunda 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."
