Sewage cleanup is the remediation of Category 3 water, what the IICRC S500 standard calls grossly contaminated water, from a sewer backup, a failed septic system or a broken waste line. It carries bacteria, viruses and parasites, so the work is closer to biohazard remediation than to ordinary water cleanup.
Power to affected areas is shut off, the source is stopped where possible, and the space is sealed off. Sewage produces hydrogen sulfide and methane, so ventilation and gas monitoring come before anyone starts cleaning.
Standing sewage and solid waste are pumped out and disposed of as regulated waste. Technicians work in full PPE, including respirators, because the contamination is biological rather than merely dirty.
Carpet, padding, insulation and drywall touched by Category 3 water are cut out and discarded. This is the part people question most, and it is not optional: porous material cannot be reliably disinfected once sewage has soaked in.
Every remaining surface is cleaned and treated with EPA-registered hospital-grade disinfectants, including framing, subfloor and any ductwork the water reached.
Air movers and dehumidifiers dry the structure to a documented moisture target, because sewage cleanup that stops at disinfection leaves you a mold job in two weeks. Readings are logged so you have evidence the building came back to dry.
Companies typically charge $100 to $200/hour for biohazard remediation labor.

Sewer backup is the most commonly misunderstood coverage in this category. A standard homeowners policy typically does not cover it, and the endorsement that does is inexpensive but has to be purchased before the loss.

Dangerous. Category 3 water can carry E. coli, salmonella, hepatitis A, giardia and other pathogens. Illness comes from ingestion, from contact with broken skin, and from aerosolised particles, which is why professional crews wear respirators rather than just gloves.
Because contamination is not the same as wetness. Sewage soaks into carpet backing and padding and carries bacteria into fibres that cannot be reliably disinfected. Under IICRC S500 the standard response to Category 3 water in porous material is removal, not drying.
Immediately. Contamination spreads as the water wicks into walls and subfloor, and mold growth begins in 24 to 48 hours. Most companies dispatch 24/7 for exactly this reason, and cost rises sharply with every hour the water sits.
A very small spill on a hard, non-porous floor can be handled with proper PPE, an EPA-registered disinfectant and careful waste disposal. Anything that reached carpet, drywall or a finished space, or anything larger than a small area, needs professional extraction and material removal.
Both, and usually the plumber first or at the same time. The plumber stops the source; the cleanup company handles the contamination. Calling only the plumber leaves you with a clean pipe and a contaminated building.
Extraction and removal are often done in one day. Drying and verification typically add three to five days, and reconstruction of what was removed is separate. Companies that promise same-day completion including drying are usually skipping the verification step.
Yes, when the source material is gone. Persistent sewage odour after cleanup almost always means contaminated material was left in place, or moisture remains in the structure. Deodorising without removal masks the problem rather than solving it.
It depends on your endorsement, not on whose pipe failed. Sewer backup coverage generally responds regardless of origin, while a policy without that endorsement generally does not. Separately, the municipality may accept a claim, so document the scene before cleanup starts.
Those still need full remediation. Sewage in a crawl space contaminates soil and framing and vents into the living space above through normal air movement. Unfinished does not mean it can be left.
Ask for the moisture logs showing the structure was dried to target, a written scope of what was removed and disinfected, and disposal documentation for the regulated waste. A company that cannot produce drying readings did not verify its own work.
