Professional remediation goes beyond surface cleaning. We test for moisture content in walls, subfloors, and structural cavities using thermal imaging cameras.

Our Step-by-Step Sewage Decontamination Process
Our certified technicians follow a proven protocol that meets or exceeds Connecticut Department of Public Health guidelines for biohazard cleanup. The process begins with safety assessment and containment to prevent cross-contamination to unaffected areas of your property.
- Emergency Containment
We establish containment barriers using 6-mil polyethylene sheeting and negative air pressure systems. This prevents contaminated air from spreading through your HVAC system or to other rooms.
- Water Extraction and Removal
Using truck-mounted extractors capable of removing 20+ gallons per minute, we extract all standing sewage. Contaminated water is pumped directly into sealed tanks for proper disposal at licensed treatment facilities.
- Demolition of Affected Materials
Porous materials like carpet, padding, drywall, and insulation that contacted sewage must be removed. We cut cleanly at the flood line to minimize repair work while ensuring all contaminated materials are eliminated.
- Antimicrobial Treatment
We apply EPA-registered antimicrobials to all affected surfaces. These treatments kill bacteria, viruses, and fungi while creating a protective barrier against future microbial growth.
- Structural Drying
Industrial dehumidifiers and air movers reduce moisture content in structural materials to safe levels. We monitor progress using moisture meters until materials reach equilibrium with ambient conditions.
- Odor Removal
Advanced oxidation processes eliminate sewage odors at the molecular level. This prevents the lingering smell that often remains after inadequate cleanup.

Understanding the root cause helps prevent future backups. Cos Cob’s infrastructure presents several unique challenges that contribute to sewage problems.

- Tree roots seeking moisture infiltrate clay sewer pipes, creating blockages that cause backups during normal usage
- High groundwater tables in low-lying areas near the Mianus River can overwhelm septic systems and municipal connections
- Aging cast iron pipes corrode from the inside, creating rough surfaces that catch debris and eventually block flow
- Improperly installed or maintained sump pumps can create hydraulic pressure that forces sewage back through floor drains
Immediate Safety Checklist: What to Do While Waiting for Help
Your safety is the top priority during a sewage backup. Follow these steps while waiting for professional help to arrive:
- Evacuate vulnerable individuals including children, elderly, and those with compromised immune systems
- Turn off electricity to affected areas if water has reached electrical outlets or devices
- Open windows for ventilation but avoid using fans that might spread contaminated air
- Remove uncontaminated valuables from affected areas if safe to do so
- Document damage with photos for insurance purposes before cleanup begins

Health Risks: Understanding Category 3 Water Contamination
Category 3 water contains harmful agents including bacteria, fungi, and viruses that can cause serious illness. The CDC reports that exposure to sewage can result in gastroenteritis, hepatitis, and skin infections. Children, elderly individuals, and those with weakened immune systems face the highest risk. CDC emergency water guidance.
Beyond immediate health risks, sewage contamination creates long-term problems if not properly addressed. Mold can begin growing within 24-48 hours in the warm, moist environment created by sewage backup. Some mold species produce mycotoxins that can cause respiratory problems and other health issues.
The Norwalk virus and other highly contagious pathogens can survive in contaminated environments for extended periods. Professional decontamination using EPA-registered antimicrobials is essential to eliminate these risks. Our technicians wear full PPE including respirators, gloves, and protective suits to prevent exposure during cleanup.
Prevention Strategies for Cos Cob Properties
While you can’t prevent all sewage backups, several measures reduce your risk. Regular maintenance of your plumbing system catches problems before they cause major damage. We recommend annual inspections of your sewer lines, especially for homes over 30 years old.
Installing backwater valves prevents sewage from flowing back into your home during system overloads. These one-way valves allow normal flow but close automatically when backflow pressure develops. Many Cos Cob homes in flood-prone areas benefit from this protection.
Proper landscaping helps manage water flow around your foundation. Ensure downspouts direct water at least 6 feet away from your home. Grade soil to slope away from your foundation to prevent water accumulation that can overwhelm your drainage system.
