Fully licensed for restoration and reconstruction work in Henniker, NH — credentials available on request before work begins.
Locally staged equipment and crews mean our Henniker response time beats out-of-area contractors every time.
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 Henniker is one job at a time. We stand behind every single one.
Our Henniker 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 Henniker 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 Henniker 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 Henniker 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 Henniker 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 Henniker 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."
"Three companies quoted our Henniker 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."
