COS Water Damage Restoration's Water Damage Restoration service in Groton covers the complete recovery process — from the first emergency response through mold prevention, structural drying, and full rebuild.
The moment your call connects, our Groton 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 Groton 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 Groton 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.

Exactly what you want from a restoration company."
"I was terrified the hardwood floors in our Groton 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."
