Category 3 black water contains dangerous human pathogens including E. coli, Salmonella, hepatitis, parasites, and toxic endotoxins. Direct exposure or inhaling aerosolized sewer gas (hydrogen sulfide) poses severe immediate health risks.
Our Step-by-Step Restoration Protocol
1. Level-C Biohazard PPE & Negative-Air Containment
Technicians suit up in certified respirators and Tyvek suits, isolating the contaminated area with sealed plastic airlocks under negative pressure.
2. Black Water Pumping & Bulk Waste Evacuation
Contaminated sewage is pumped into sealed recovery units and transported for regulated municipal disposal according to environmental codes.
3. Removal of Contaminated Porous Building Materials
Soaked carpet, padding, tack strips, and saturated drywall are carefully cut, double-bagged, and removed to prevent biohazard spread.
All framing studs and subfloors are treated with hospital-grade broad-spectrum biocides, followed by thermal fogging and HEPA air scrubbing.

Service Questions & Answers
Can we stay in the home while sewage cleanup is taking place?+
No. Airborne bacteria, microbial volatile organic compounds (MVOCs), and sewer gases can cause acute respiratory distress. We recommend staying clear until negative-air scrubbing and sanitization are complete.
Is sewage backup covered by standard Arizona home insurance?+
Sewage backups typically fall under a "Water Backup & Sump Overflow" policy endorsement. We check your specific policy endorsements and submit Xactimate estimates directly to your carrier.
