Sewage Cleanup — Bellevue FAQs
Real answers to the questions we hear every week.
Do you work with insurance?
Yes — we bill your insurance directly. We handle the photo documentation, moisture readings, scope sheets, and Xactimate line items that adjusters need. You pay your deductible; we invoice your carrier for the rest. If an adjuster pushes back on a line item we know is covered, we stay on the file until it's resolved.
Are your technicians licensed and insured?
Every technician on a Complete Restoration of Bellevue job is licensed or IICRC-certified, with a minimum of 5 years of field experience. We carry general liability and workers' comp insurance, and we'll provide proof on request before we start work.
What's the difference between "clean water," "gray water," and "black water"?
Clean (Category 1) water comes from a supply line — tap, toilet supply, appliance supply — and has no contaminants. Gray (Category 2) water comes from sinks, washing machines, or dishwashers and contains mild contaminants. Black (Category 3) water includes sewage, toilet overflow with waste, or any water that has sat long enough to grow bacteria. Category determines what materials can be saved versus what must be removed and disposed of — it's a central decision on every job.
Can carpet be saved after a sewage backup?
No. Category 3 black water carpet must be removed and disposed of — IICRC S500 standards are clear on this and no reputable restorer will try to "clean" sewage-soaked carpet. Pad is always removed. Hardwood and tile in a sewage-affected area are evaluated case by case; concrete slab can usually be remediated in place after thorough disinfection.
Does insurance cover sewer backup in Washington?
Only if your policy has a sewer or water back-up endorsement — this is a separate endorsement, not part of standard WA homeowners. Common sublimits are $5,000, $10,000, or $25,000. We'll help you read your declarations page before we write the scope.
