Every technician holds active NY contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Rosedale job.

Our reputation in Rosedale is one job at a time. We stand behind every single one.
COS Water Damage Restoration's Water Damage Restoration service in Rosedale covers the complete recovery process — from the first emergency response through mold prevention, structural drying, and full rebuild.
Speed at this phase directly determines how much is salvageable. Our Rosedale crews don't slow down on the way to your property.
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 Rosedale 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.
Supplement filing for underpaid Rosedale claims is part of the service.
One company, start to finish.

"Our Rosedale 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."
"The insurance side of a water damage claim is overwhelming. COS Water Damage Restoration's Rosedale team handled everything — filed the first notice, attended the adjuster visit, and got us a fair settlement. I didn't make a single insurance phone call myself."
"Three companies quoted our Rosedale water damage restoration. COS Water Damage Restoration was the only one who walked every room with instruments before quoting, explained each line of the estimate, and committed to the timeline in writing. They came in on time, on scope, and the claim went through without a single supplemental dispute."
