Here's what separates COS Water Damage Restoration's Water Damage Restoration service from every other option in Greenport.
Fully licensed for restoration and reconstruction work in Greenport, NY — credentials available on request before work begins.
Our Greenport-based crews target 60-minute on-site response. We don't route your emergency through a regional call center — local dispatch means faster arrival and better outcome.
We quote in writing before we start. What you approve is what you pay.
Our reputation in Greenport is one job at a time. We stand behind every single one.
Our Greenport Water Damage Restoration team handles every phase of recovery in-house: no subcontracting, no coordination gaps, no handoff problems.
The moment your call connects, our Greenport restoration dispatcher starts building your response. Extraction crews arrive with truck-mounted systems capable of removing high volumes of water rapidly — limiting saturation time and reducing the overall restoration scope.
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 Greenport 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.
Our Greenport claim coordinators build your documentation file from day one: structured photo evidence, moisture data logs, equipment placement records, and an Xactimate scope of work that matches your carrier's estimating platform. We file, communicate with your adjuster, and follow the claim through to settlement so you don't have to.
When drying is confirmed complete, our licensed Greenport reconstruction team handles all rebuild work — drywall, flooring, painting, trim, structural framing — under the same project manager who ran the restoration phase. No handoff to an unknown subcontractor, no coordination gap, no restart of the communication process.


Call +1-844-499-0972 any time — a live Greenport dispatcher answers immediately, gathers the details, and deploys the nearest crew. No voicemail, no automated queue, no call-back-tomorrow policy.
Local crews mean local speed — we know Greenport's roads and we move fast.
No work starts without your written approval of the scope and cost.
Written satisfaction guarantee on every Greenport job.



"Our Greenport 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."
"I was terrified the hardwood floors in our Greenport home were gone after the flooding. The COS Water Damage Restoration crew brought in mat drying systems and dried them in place — saved us thousands versus replacement. The project manager called every morning with readings. Outstanding."
"Mold discovered during our Greenport renovation led us to COS Water Damage Restoration. The remediation was thorough, the clearance report was accepted by our contractor and insurer on the first submission, and we were back on schedule within the week."
