COS Water Damage Restoration's Water Damage Restoration service in Charlestown 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 Charlestown crews don't slow down on the way to your property.
Thermal imaging cameras and calibrated moisture meters map the full extent of water migration in your Charlestown 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 Charlestown 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.
We don't rebuild over hidden mold risk.
Our Charlestown 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.
When drying is confirmed complete, our licensed Charlestown 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.

"Our Charlestown 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 Charlestown 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 Charlestown 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."
