Here's what separates COS Water Damage Restoration's Water Damage Restoration service from every other option in Williston.
Every technician holds active ND contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Williston job.
Our Williston-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.
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 Williston is one job at a time. We stand behind every single one.
Our Williston 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 Williston 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 Williston 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 Williston 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 Williston 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 Williston 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 Williston 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 Williston's roads and we move fast.
No work starts without your written approval of the scope and cost.
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 Williston 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 Williston 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 Williston 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."
