NYS and NYC M/WBE Certified Contractor
You get your space back without the smell, the health risks, or the worry. Your floors are dry, your air is clean, and your property is restored to pre-damage condition.
No more wondering if harmful bacteria are lurking in hidden corners. No more sleepless nights worrying about mold growth or structural damage. Just a completely sanitized space that’s safe for your family or customers again.
We handle everything from the initial extraction to the final deodorization, so you can focus on getting back to normal life instead of managing a health hazard.
Green Island Group has been serving New York City’s unique sewage cleanup needs for years. We understand how Chinatown’s aging infrastructure and high-density buildings create specific challenges when sewage backups occur.
We know that in neighborhoods like Chinatown, sewage problems can quickly affect multiple units or spread through shared plumbing systems. We respond fast because we’ve seen how quickly contamination spreads in these older buildings.
Local residents trust us because we show up when we say we will, work efficiently to minimize disruption, and handle insurance claims directly so you don’t have to fight for coverage.
First, we assess the contamination level and secure the area to prevent further spread. We arrive with full protective equipment and industrial-grade extraction tools designed specifically for hazardous waste removal.
Next comes complete sewage extraction using truck-mounted vacuum systems, followed by thorough sanitization with EPA-registered disinfectants. We don’t just clean surfaces—we eliminate bacteria, viruses, and parasites that can cause serious illness.
Finally, we dry everything completely using commercial dehumidifiers and air movers, then treat all affected areas with professional-grade deodorizers. We also handle any necessary minor repairs and coordinate with your insurance company for direct billing.

Your sewage cleanup includes hazardous waste extraction, structural drying, biohazard sanitization, and odor elimination. We also remove and properly dispose of contaminated materials like drywall, insulation, and carpeting that can’t be safely restored.
In Chinatown’s dense urban environment, we understand the urgency of preventing cross-contamination between units. We use containment barriers and negative air pressure systems to keep contamination isolated while we work.
We also provide thermal imaging to detect hidden moisture in walls and floors—critical in older buildings where sewage can seep into unexpected places. Every surface gets tested to ensure complete dryness before we consider the job finished.
We provide 24/7 emergency response and typically arrive within an hour of your call in Chinatown. Sewage cleanup is always treated as a health emergency because harmful bacteria like E. coli and Salmonella can survive in contaminated areas for 24 hours or longer.
Our rapid response matters because the longer sewage sits, the deeper it penetrates into porous materials like drywall and flooring. Quick action prevents more extensive damage and reduces the risk of mold growth, which can begin within 24-48 hours of moisture exposure.
We keep fully equipped trucks ready at all times, so we arrive with everything needed for immediate containment and extraction. No waiting for equipment or making multiple trips while contamination spreads.
Sewage contains dangerous pathogens including bacteria, viruses, parasites, and other illness-causing microorganisms. Direct exposure can lead to digestive problems, respiratory issues, skin infections, and more serious conditions like hepatitis.
In Chinatown’s older buildings with shared plumbing systems, contamination can quickly spread through connected pipes, ventilation systems, and common walls. This creates risks not just for the affected unit, but for neighboring apartments and commercial spaces.
Raw sewage is classified as Category 3 “black water”—the most dangerous type of water damage. That’s why professional cleanup isn’t optional—it’s critical for protecting your health and meeting safety standards required by NYC building codes.
Most homeowner’s and commercial insurance policies include coverage for sewage backup cleanup, especially when caused by sudden pipe failures or city sewer system problems. We work directly with insurance companies and handle claims paperwork to maximize your coverage.
We document everything thoroughly with photos and detailed reports that insurance adjusters need for claim approval. We know exactly what information insurers require and how to present damage assessments for fastest claim processing.
We also offer direct billing to your insurance company when possible, so you don’t have to pay upfront and wait for reimbursement. This helps you get professional cleanup started immediately without worrying about out-of-pocket costs.
We establish containment barriers immediately upon arrival to isolate the contaminated area from clean spaces. We use negative air pressure systems and plastic sheeting to prevent airborne contaminants from spreading through your building’s ventilation system.
All contaminated materials get sealed in biohazard bags before removal, and we create designated pathways for carrying waste out of the building. This prevents tracking contamination through hallways or common areas that other residents use.
We also coordinate with building management when necessary to temporarily shut off shared plumbing connections or ventilation systems. In Chinatown’s connected building structures, this coordination is essential for preventing contamination from reaching neighboring units.
DIY sewage cleanup puts your health at serious risk and often fails to eliminate dangerous bacteria hiding in porous materials. Standard household cleaners and equipment can’t handle Category 3 contamination or reach moisture trapped inside walls and flooring.
Professional restoration uses hospital-grade EPA-registered disinfectants, industrial extraction equipment, and specialized techniques for complete decontamination. We also have thermal imaging technology to detect hidden moisture that leads to mold growth weeks later.
Most importantly, we follow strict safety protocols with proper protective equipment to prevent exposure to dangerous pathogens. Insurance companies also typically require professional cleanup for sewage claims, so DIY attempts can void your coverage.
Most sewage cleanup projects in Chinatown take 3-5 days from initial extraction to final restoration, depending on the extent of contamination and materials affected. Emergency extraction and sanitization happen immediately, usually within the first 24 hours.
Structural drying typically takes 2-3 additional days using commercial dehumidifiers and air movers. We monitor moisture levels continuously and won’t begin restoration work until everything reaches proper dryness standards to prevent mold growth.
Minor repairs like drywall replacement or floor refinishing add 1-2 days to the timeline. We coordinate all work to minimize disruption to your daily routine and keep you informed of progress at each step of the restoration process.
