Professional Sewage & Blackwater Cleanup
Sewage backup (Category 3 water) poses serious health hazards from bacteria, viruses, and parasites. Professional handling is essential—DIY cleanup risks exposure to E. coli, Hepatitis A, tetanus, and other pathogens. IICRC standards require full removal of affected porous materials, antimicrobial treatment, and air quality verification.
Our biohazard-trained technicians use full PPE including Tyvek suits, N95 respirators, and chemical-resistant gloves. We follow EPA and OSHA protocols for contaminated material handling and disposal. Beyond extraction, we apply hospital-grade disinfectants and verify air quality before clearance.
Our Sewage & Blackwater Cleanup Process
- Technicians arrive in full PPE (Tyvek, N95, chemical gloves)
- Contain affected area to prevent cross-contamination
- Extract sewage using dedicated contamination pumps (separate from clean water equipment)
- Remove and bag all porous materials (carpet, pad, drywall to 24" above contamination)
- HEPA vacuum all surfaces to remove dried contamination
- Apply hospital-grade antimicrobial treatment (quaternary ammonium compounds)
- Treat subfloor with biocide and encapsulant
- Set up HEPA air scrubbers and dehumidifiers
- Conduct post-remediation air quality testing
- Provide clearance documentation for insurance
Equipment & Technology
- Dedicated Category 3 extraction equipment (never mixed with clean water jobs)
- HEPA air scrubbers capturing particles to 0.3 microns
- Hospital-grade disinfectants (EPA-registered for sewage pathogens)
- Personal protective equipment (Tyvek suits, N95+ respirators, chemical-resistant gloves)
- Biohazard waste containers and disposal coordination
- ATP testing meters for surface contamination verification
Pricing
Sewage cleanup is more expensive due to hazmat protocols—expect $3,500-$10,000 for typical residential incidents. Extensive contamination affecting multiple rooms or finished basements can exceed $15,000. Insurance typically covers sudden backup; may exclude neglected drain maintenance.
Timeline
Extraction and contaminated material removal completed within 24 hours. Drying and antimicrobial treatment 3-5 days. Clearance testing before reconstruction begins.
When You Need Sewage & Blackwater Cleanup
- Municipal sewer line backup into home
- Septic system failures
- Floor drain backups from heavy rain
- Toilet overflows with sewage
- Sump pump failure with sewer connection
- Any flood water mixed with sewage or septic
Frequently Asked Questions
Is sewage cleanup dangerous?
Extremely. Sewage contains bacteria, viruses, and parasites that cause serious illness. Never attempt DIY cleanup—professional hazmat protocols protect your family and ensure proper decontamination.
Can anything be saved after sewage backup?
Non-porous items (glass, metal, hard plastic) can be disinfected. Porous materials (carpet, drywall, upholstered furniture) must be removed per IICRC S500 standards.
How do you verify the area is safe?
We conduct ATP testing (measures biological contamination) and air quality testing after cleanup. You receive clearance documentation before any reconstruction begins.
