Four reasons Bellingham 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 Bellingham job.
Our Bellingham-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.
Our reputation in Bellingham is one job at a time. We stand behind every single one.
Our Bellingham 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 Bellingham 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 Bellingham 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 Bellingham 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 Bellingham 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.

"Our Bellingham 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."
"I was terrified the hardwood floors in our Bellingham 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 Bellingham 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."
