Sewage Cleanup in Seattle, WA
We've worked on sewage cleanup jobs across Seattle long enough to know what tends to break here, when, and why. Our pricing's flat-rate, our techs are state-licensed, and our trucks have parts on them. Most jobs done the same visit.
One we ran last year
Property manager call, Seattle-area duplex. Both units had raw sewage backed up through basement floor drain after city sewer main blockage. We pulled the system apart and found municipal main blockage upstream. Category 3 protocol, removed contaminated materials, full antimicrobial treatment, structural drying, claim filed against city for upstream cause on the same trip — both tenants happy. $1375.
What's typical for this job
Sewage cleanup is regulated as Category 3 (black water) work under IICRC S500. That means biohazard PPE — Tyvek suits, respirators, full eye protection — for the crew, plus containment-zone protocol around the affected area.
Porous materials in direct contact with sewage cannot be effectively decontaminated. Carpet, padding, drywall to 12 inches above the line, baseboards, and unfinished wood typically require removal and disposal as biohazard waste.
Hard surfaces are sanitized with EPA-registered antimicrobials. Air scrubbers with HEPA and activated-carbon filters run during the work to control airborne pathogens and odor.
Documentation is critical. Insurance adjusters reject sewage claims that don't show category determination, S500 protocol followed, and EPA-product use logs.
