A flood event in Chanhassen brings everything the water touched into contact with contaminants from storm drains, sewage lines, and surface runoff. The cleanup process has to account for all of it — not just the visible mess.
Flood cleanup in Chanhassen is a specialized discipline — not standard water damage restoration with a different name. The contamination profile, debris volume, and structural concerns that come with flood events require specific training, equipment, and protocols.
Proper flood cleanup in Chanhassen requires treating the water as contaminated until testing confirms otherwise.
Our Chanhassen-based Flood Damage Cleanup crew targets 60-minute arrival after your call. After a flood event, every hour of additional exposure increases contamination spread and structural saturation — speed of response directly limits the total recovery scope and cost.
Flood events deposit sediment, debris, and waterlogged materials that standard water damage cleanup doesn't address. Our Chanhassen team handles full debris removal — furniture, flooring, drywall that can't be salvaged, sediment deposits — and disposes of it properly before structural drying begins.
Flat-rate pricing, in writing, before any equipment is deployed — that's the standard on every Chanhassen job.
COS Water Damage Restoration's Chanhassen flood team handles the complete recovery process — from the first pump-out through final antimicrobial treatment and reconstruction. Each phase requires specific expertise and equipment.
The first priority in any Chanhassen flood event is getting the water volume down as fast as possible — limiting additional saturation of structural materials and preventing the contaminated water from spreading further into the property. We deploy submersible pumps for deep standing water, then transition to truck-mounted extraction for residual volume, working until the visible water is completely removed before debris removal begins.
Incomplete debris removal under drying equipment is one of the most common sources of post-flood mold in Chanhassen properties.
Treatment is applied to framing, subfloor sheathing, concrete, and masonry before drying begins — not after.
Structural drying doesn't complete when the room "feels dry" — it completes when the instrument readings confirm it.
We file the claim, coordinate the adjuster visit, and follow the settlement through — so you're not navigating the insurance complexity on top of the property damage.
After drying is confirmed complete, our licensed Chanhassen reconstruction team rebuilds what the flood took: new drywall, flooring, insulation, paint, trim, and any structural framing that required replacement. All reconstruction work is documented to the same standard as the cleanup phase — supporting your insurance settlement and providing you with a verifiable record of the complete recovery.


Flooding doesn't wait, and neither do we. Live dispatch, immediate crew deployment.
Our Chanhassen crew arrives with pumping equipment, contamination PPE, extraction gear, and assessment tools configured for flood response — not standard water damage equipment. Target arrival in 60 minutes or less.
Before any work begins, our Chanhassen team conducts a complete flood damage assessment: water category determination, contamination extent mapping, debris volume evaluation, and structural material viability review. A written, Xactimate-based estimate is prepared and reviewed with you before any pumping or removal starts.
Pumping, extraction, debris removal, antimicrobial treatment, structural drying, and reconstruction proceed under your approved scope. Daily progress updates keep you informed, and final sign-off happens with you at a completed walkthrough.



"Our Chanhassen restaurant flooded during a major storm event. COS Water Damage Restoration handled the flood cleanup with commercial-scale equipment, coordinated around our equipment and walk-in units to protect anything salvageable, and had us reopened four days sooner than any other company we got quotes from. The insurance documentation they prepared was detailed enough that our adjuster approved the scope on the first submission. Outstanding."
"The antimicrobial treatment step was what convinced me that COS Water Damage Restoration knew what they were doing. After flood water, every company I talked to mentioned drying — but only COS Water Damage Restoration specifically walked me through the contamination treatment that happens before drying starts. That's the step that prevents mold, and they didn't skip it to save time or money. Our Chanhassen home came out of the restoration clean and structurally sound."
"What made COS Water Damage Restoration stand out during our Chanhassen flood event was the speed combined with the completeness. They weren't rushing through steps to move on to the next job — they pumped completely, removed every piece of wet material that needed to go, treated the structural surfaces thoroughly, and then set up drying equipment in a configuration that actually addressed all the affected areas including a tight crawlspace access. Attention to detail that I didn't expect from a company working under emergency conditions."
