Four reasons Grandview 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 WA contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Grandview job.
Our Grandview-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.
Every Water Damage Restoration job in Grandview 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 Grandview 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 Grandview 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 Grandview 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 Grandview 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 Grandview 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.


Real person, real dispatch. Call +1-844-499-0972 and your Grandview crew is moving before you hang up.
Our Grandview 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.
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.
