A flood event in Long Key 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.
Here's what COS Water Damage Restoration brings to every Flood Damage Cleanup job in Long Key that separates genuine flood recovery from a surface cleanup.
Flood water in Long Key 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 Long Key, 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 Long Key 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 Long Key job.
COS Water Damage Restoration's Long Key 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 Long Key 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.
After the water is out, the debris starts. Flood events in Long Key leave behind sediment, organic material, waterlogged furniture and belongings, and materials that absorbed contaminated water and cannot be safely dried in place — drywall, carpet, pad, and insulation being the most common. Our Long Key crew performs full debris removal and regulated disposal, leaving a clean structural shell ready for proper drying and treatment.
Every structural surface that came in contact with Category 2 or Category 3 flood water in Long Key receives antimicrobial treatment before drying equipment is staged. This is not optional — it's the only way to prevent microbial colonization from starting during the drying cycle, which typically runs 3-7 days and creates ideal temperature and humidity conditions for mold growth if untreated surfaces are present.
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.
One company from flood water to finished restoration. No handoffs, no coordination gap.

"Our Long Key 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 Long Key team was professional from the first phone call to the final walkthrough."
