Do not attempt cleanup yourself — call us immediately and our sewage contamination control service will follow strict IICRC-compliant safety protocols to remediate your property.

Category 3 Water & Our Safety Protocols
The IICRC S500 water damage standard classifies sewage backups, toilet overflows involving waste, and flooding from rivers or streams as Category 3 water — commonly called "black water." This classification means the water may contain bacteria, viruses, and other contaminants, and it requires different handling than clean or gray water losses. We don't diagnose or make specific medical claims about exposure; if you have health concerns related to a sewage backup, consult a physician.
Because of that classification, our technicians follow IICRC-compliant safety protocols on every sewage job: full personal protective equipment (PPE) including protective suits, gloves, boot covers, and respirators; containment of the affected area to prevent cross-contamination; disposal of unsalvageable porous materials that can't be safely decontaminated; and EPA-registered antimicrobial treatment of all surfaces that remain. This isn't a job for household cleaning products or a wet/dry vacuum — call us before attempting any cleanup yourself.
Sprinkler & Fire Suppression Discharge Cleanup
Sewage water damage isn't the only Category 3 or near-Category-3 loss commercial properties face. An accidental fire sprinkler discharge or fire suppression system release can send hundreds of gallons of water through a building in minutes, and the water sitting in old, rarely-flushed sprinkler piping is often stagnant and contains rust, sediment, and bacteria that require the same containment and antimicrobial treatment as a sewage backup. We provide the same rapid extraction, decontamination, and structural drying response for offices, warehouses, retail spaces, and multi-tenant buildings affected by sprinkler or fire suppression discharge, with direct commercial insurance billing available.
