When water has damaged your Merrick property, every hour without professional intervention expands the loss. Our IICRC-certified Water Damage Restoration team arrives fast, assesses completely, and restores systematically — from initial extraction through final reconstruction.
Crew stationed in Merrick — not routed from another region.
Industry credentials that matter.
No surprises — flat rate, in writing.
Your adjuster hears from us, not you.
Four reasons Merrick homeowners and businesses call COS Water Damage Restoration first when water damage strikes — and give us five stars when we're done.
Every technician holds active NY contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Merrick job.
Our Merrick-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.
Xactimate-based scope of work reviewed with you before any equipment is placed. The estimate you approve is the invoice you receive — no hidden line items, no after-the-fact surprises.
Our reputation in Merrick is one job at a time. We stand behind every single one.
Our Merrick Water Damage Restoration team handles every phase of recovery in-house: no subcontracting, no coordination gaps, no handoff problems.
Speed at this phase directly determines how much is salvageable. Our Merrick 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.
We don't rebuild over hidden mold risk.
Supplement filing for underpaid Merrick claims is part of the service.
When drying is confirmed complete, our licensed Merrick 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.


Real person, real dispatch. Call +1-844-499-0972 and your Merrick crew is moving before you hang up.
Our Merrick crew targets on-site arrival in 60 minutes or less, staging extraction equipment and containment supplies during transit so they're productive the moment they arrive.
No work starts without your written approval of the scope and cost.
Written satisfaction guarantee on every Merrick job.
