No surprises — flat rate, in writing.

Here's what separates COS Water Damage Restoration's Water Damage Restoration service from every other option in Walnut.
Every technician holds active IL contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Walnut job.
Our Walnut-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 Walnut 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 Walnut 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 Walnut 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 Walnut 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.
Supplement filing for underpaid Walnut claims is part of the service.
When drying is confirmed complete, our licensed Walnut 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 Walnut crew is moving before you hang up.
Our Walnut 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 Walnut job.
