A flood event in Greendale 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 Greendale 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.
Flood water in Greendale is classified as Category 2 or Category 3 — containing contaminants from storm drains, agricultural runoff, or sewage intrusion. Our crew uses the correct containment, PPE, extraction equipment, and disposal procedures for contaminated water events — not standard water damage methods.
We're based in Greendale, not dispatched from a regional hub. That's what makes fast response possible.
Flood events deposit sediment, debris, and waterlogged materials that standard water damage cleanup doesn't address. Our Greendale 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 Greendale job.
COS Water Damage Restoration's Greendale 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 Greendale 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 Greendale properties.
Treatment is applied to framing, subfloor sheathing, concrete, and masonry before drying begins — not after.
Post-flood structural drying in Greendale is more complex than standard water damage drying because contaminated events often require partial material removal (wet drywall, insulation, flooring) to access structural assemblies for drying. Our Greendale drying crew deploys calibrated LGR dehumidifiers and air movers after material removal and antimicrobial treatment, taking daily moisture readings at fixed sensor points until all assemblies reach documented equilibrium moisture content targets.
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.
One company from flood water to finished restoration. No handoffs, no coordination gap.


Call +1-844-499-0972 and a live Greendale dispatcher answers — not an automated queue. Your situation is assessed, the nearest Greendale flood crew is dispatched, and your estimated arrival is confirmed during the call.
Flood cleanup requires flood-specific equipment. Our Greendale crews arrive prepared for the full scenario.
Before any work begins, our Greendale 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 Greendale 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."
"I went through Flood Damage Cleanup with another company two years ago after a different storm. That company dried without properly removing saturated materials, and we had mold problems within a month. This time I chose COS Water Damage Restoration. They took out everything that couldn't be safely dried, treated the framing, and ran a proper drying program with daily readings. No mold. No repeat issues. I should have called them the first time."
"The estimate conversation before any work started was exactly what I needed. After a flood you feel powerless — the written pricing discussion gave me back a sense of control. I knew what was happening, why, and what it would cost before anything began. COS Water Damage Restoration's Greendale team was professional from the first phone call to the final walkthrough."
