Toilet overflows, sewer backups, septic spills — all Category 3 black water requiring biohazard protocols. Our IICRC-certified crews respond 24/7 with full PPE, EPA-registered hospital-grade disinfectants, and complete sanitization.
Sewage cleanup is the IICRC S500-governed process of removing, sanitizing, and restoring property contaminated by Category 3 black water. Per IICRC standards, sewage is the textbook example of Category 3 water — grossly contaminated with pathogens, toxigenic substances, and harmful agents.
The pathogens in sewage create serious health risks: E. coli, Salmonella, Hepatitis A virus, Norovirus, and other bacteria that cause gastrointestinal illness, wound infections, skin rashes, and respiratory problems. Contact with raw sewage requires immediate professional response — not just to restore your property, but to protect your family's health.
Sewage cleanup is NOT standard water damage cleanup. It requires Tyvek Level C PPE, N95 or P100 respirators, nitrile gloves, full-body suits, and EPA-registered hospital-grade disinfectants. Porous materials contaminated by sewage — carpet, padding, drywall below the water line — must be removed and disposed of as biohazardous waste. The remaining structural elements receive antimicrobial treatment with phenolics or quaternary ammonium compounds.
Important: DIY sewage cleanup can void your insurance claim and create OSHA-reportable health exposures. Texas insurance adjusters require professional documentation, and the contamination risks are real. Call us before touching anything.
Sewage backups have multiple sources, and each requires slightly different protocols:
All five require the same biohazard-grade protocols, but each comes with different insurance considerations and contamination patterns. We handle every type with the same OSHA-compliant approach.
Every project follows IICRC S500 Category 3 protocols and OSHA's Bloodborne Pathogens Standard (1910.1030).
Crews arrive within 60 minutes in full PPE. We establish containment to prevent cross-contamination of clean areas. HEPA air scrubbers run during work.
We identify and stop the source — main line cleanout, septic intervention, or municipal coordination. Cleanup is impossible while contamination continues.
Contaminated carpet, padding, drywall (12-24 inches above the water line), and porous contents are bagged and disposed of as regulated waste per OSHA protocols.
Truck-mounted extractors remove standing sewage water. LGR dehumidifiers and air movers dry remaining structural materials to pre-loss moisture content.
EPA-registered hospital-grade disinfectants treat every surface. Phenolics and quaternary ammonium compounds kill pathogens. Air sanitization with ULV fogging.
New drywall, insulation, flooring, and finishes installed. ATP testing optionally confirms sanitization. Complete documentation for your insurance carrier.
Bathroom sewage backup with antimicrobial treatment and floor restoration.
Rural/exurban septic overflow cleanup with TCEQ-compliant disposal.
Municipal sewer backup cleanup with full Cat 3 protocols.
Fast water extraction, drying, and mold prevention after pump failure.
Broken/collapsed sewer line cleanup with structural restoration.
Full hazmat remediation beyond sewage — OSHA-compliant throughout.
Sewer backup is a notable exception in Texas homeowners insurance. Standard policies typically exclude sewer backup unless you carry a specific endorsement.
Most carriers offer water backup coverage endorsements in $5,000, $10,000, or $25,000 amounts — but you have to add it to your policy specifically. We help determine your coverage before work begins and bill insurance directly using Xactimate documentation matching every major Texas carrier's pricing model.

Sewage cleanup with water backup endorsement
"Our main line backed up during the May rains. They were here in 45 minutes with full PPE. Insurance billing through Allstate's water backup endorsement was seamless — covered everything."
"Septic system failed on a holiday weekend. They came out, contained the spill, and worked through the weekend. The TCEQ documentation they provided made our septic permit renewal go smoothly."
"Toilet overflow on the second floor of our apartment complex. They contained it before it reached the unit below, full sanitization, and the property manager got clean documentation for the tenants' insurance claims."
Yes. Sewage contains pathogens including E. coli, Salmonella, Hepatitis A, and Norovirus that cause gastrointestinal illness, wound infections, and respiratory problems. IICRC S500 classifies sewage as Category 3 black water requiring full PPE, biohazard waste disposal, and EPA-registered hospital-grade disinfectants. Skin contact, inhalation of aerosols, and especially ingestion are all serious health risks.
Sewer backup requires a specific water backup endorsement on most Texas homeowners policies, typically $5,000 to $25,000 in coverage. Standard HO-3 and HO-A policies often exclude sewer backup. We help determine your coverage before work begins and bill insurance directly.
No. DIY sewage cleanup creates serious health risks and can void insurance claims. Category 3 water requires Tyvek Level C PPE, N95/P100 respirators, hospital-grade disinfectants, mandatory porous material disposal, and biohazard waste protocols per OSHA's Bloodborne Pathogens Standard (1910.1030).
Initial cleanup and sanitization typically takes 1-3 days. Drying takes 3-7 days. Reconstruction (drywall replacement, flooring, paint) adds 1-2 weeks. Total project time: 2-3 weeks for residential sewage events of moderate size.
Houston Public Works can sometimes be liable for damages from municipal sewer system failures. We document the source thoroughly with photos, video, and Xactimate scoping so you can pursue a claim against the city in addition to your homeowners coverage. This documentation has helped multiple Houston customers recover costs from the municipality.
