Sewage Cleanup in Washington, DC
Honestly, most sewage cleanup questions can be answered over the phone. Save yourself the dispatch fee — call first, ask second. Family-run, second-generation if you count my dad. We've watched fifteen national "plumbing chains" come and go in Washington and we're still here.
Notes on Washington housing stock
If you're inside the city limits, we're typically there inside an hour during business hours. Outside the metro, plan on a bit longer.
That said, newer construction in Washington has its own set of typical issues. We see both.
What we cover
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.

Sample job
Got a call last month from a the south side Washington home — any era build. Symptom: raw sewage backed up through basement floor drain after city sewer main blockage. Cause: municipal main blockage upstream. Category 3 protocol, removed contaminated materials, full antimicrobial treatment, structural drying, claim filed against city for upstream cause, all done in the same visit, billed flat-rate at $275.
