COS Water Damage Restoration's Water Damage Restoration service in Mukilteo covers the complete recovery process — from the first emergency response through mold prevention, structural drying, and full rebuild.
The moment your call connects, our Mukilteo restoration dispatcher starts building your response. Extraction crews arrive with truck-mounted systems capable of removing high volumes of water rapidly — limiting saturation time and reducing the overall restoration scope.
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 Mukilteo 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.
Antimicrobial treatment is applied to all moisture-exposed structural surfaces as a standard preventive step in every Mukilteo Water Damage Restoration job. Where mold growth is identified, IICRC S520-compliant remediation — with HEPA containment, negative air pressure, and clearance testing — is performed before reconstruction begins.
Our Mukilteo 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 Mukilteo dispatcher answers immediately, gathers the details, and deploys the nearest crew. No voicemail, no automated queue, no call-back-tomorrow policy.
Our Mukilteo 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 Mukilteo job.
