Our New Suffolk 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 New Suffolk 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.
Thermal imaging cameras and calibrated moisture meters map the full extent of water migration in your New Suffolk property — identifying affected wall cavities, subfloor assemblies, and ceiling materials that aren't visible on the surface. A complete damage picture drives a more accurate scope and a faster insurance claim.
Industrial LGR dehumidifiers and high-velocity air movers are deployed in calculated configurations based on your New Suffolk property's materials, square footage, and psychrometric conditions. Daily readings at fixed sensor points document the drying progression until all assemblies reach target equilibrium moisture content.
Antimicrobial treatment is applied to all moisture-exposed structural surfaces as a standard preventive step in every New Suffolk 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 New Suffolk 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.
One company, start to finish.

"Our New Suffolk 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 New Suffolk 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 New Suffolk 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."
