A flood event in Unionville 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 Unionville that separates genuine flood recovery from a surface cleanup.
Proper flood cleanup in Unionville requires treating the water as contaminated until testing confirms otherwise.
We're based in Unionville, not dispatched from a regional hub. That's what makes fast response possible.
You can't dry a space that still has saturated debris in it. Full cleanup is the prerequisite for effective structural drying.
Flat-rate pricing, in writing, before any equipment is deployed — that's the standard on every Unionville job.
COS Water Damage Restoration's Unionville 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 Unionville 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 Unionville properties.
Treatment is applied to framing, subfloor sheathing, concrete, and masonry before drying begins — not after.
Post-flood structural drying in Unionville 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 Unionville 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.


Flooding doesn't wait, and neither do we. Live dispatch, immediate crew deployment.
Our Unionville 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 Unionville 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 Unionville 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 Unionville home came out of the restoration clean and structurally sound."
"What made COS Water Damage Restoration stand out during our Unionville 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."
