Four reasons Nitro homeowners and businesses call COS Water Damage Restoration first when water damage strikes — and give us five stars when we're done.
Every technician holds active WV contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Nitro job.
Our Nitro-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.
Every Water Damage Restoration job in Nitro carries our written satisfaction guarantee. If the result doesn't meet the documented standard, we return and make it right at zero additional cost.
Our Nitro 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 Nitro 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.
We don't rebuild over hidden mold risk.
Our Nitro 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 Nitro 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.


Call +1-844-499-0972 any time — a live Nitro dispatcher answers immediately, gathers the details, and deploys the nearest crew. No voicemail, no automated queue, no call-back-tomorrow policy.
Our Nitro crew targets on-site arrival in 60 minutes or less, staging extraction equipment and containment supplies during transit so they're productive the moment they arrive.
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.
Written satisfaction guarantee on every Nitro job.



"Our Nitro 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."
"The insurance side of a water damage claim is overwhelming. COS Water Damage Restoration's Nitro team handled everything — filed the first notice, attended the adjuster visit, and got us a fair settlement. I didn't make a single insurance phone call myself."
"Three companies quoted our Nitro 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."
