Here's what separates COS Water Damage Restoration's Water Damage Restoration service from every other option in Johnston.
Every technician holds active SC contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Johnston job.
Our Johnston-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.
We quote in writing before we start. What you approve is what you pay.
Our reputation in Johnston is one job at a time. We stand behind every single one.
Our Johnston 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 Johnston crews don't slow down on the way to your property.
Every affected assembly is documented with instrument readings before drying begins.
Industrial LGR dehumidifiers and high-velocity air movers are deployed in calculated configurations based on your Johnston 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 Johnston 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.


Call +1-844-499-0972 any time — a live Johnston dispatcher answers immediately, gathers the details, and deploys the nearest crew. No voicemail, no automated queue, no call-back-tomorrow policy.
Local crews mean local speed — we know Johnston's roads and we move fast.
A thorough walk-through with moisture instruments and thermal imaging establishes the full scope of loss. You receive a written, itemized Xactimate estimate before any work begins — signed off by you before the first tool is placed.
Extraction, drying, remediation, and reconstruction proceed under daily monitoring and documented progress reporting. The job isn't complete until final moisture readings confirm success and you've conducted the walkthrough with your project manager.



"After a supply line failure soaked our kitchen and part of the living room, COS Water Damage Restoration was at our Johnston home in under an hour. The crew's moisture mapping caught wet wall cavity areas I never would have known about. Five days of drying, a perfectly documented insurance file, and zero mold issues. Exactly what you want from a restoration company."
"I was terrified the hardwood floors in our Johnston 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 Johnston 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."
