NYS and NYC M/WBE Certified Contractor
You get your property back to pre-damage condition without the lingering odors, health hazards, or structural damage that sewage leaves behind. No more worrying about hidden moisture breeding mold in your walls or floors.
Your family can return to a space that’s been thoroughly sanitized and restored by professionals who understand the serious health risks sewage presents. You’ll have complete documentation for your insurance claim and the peace of mind that comes from knowing the job was done right the first time.
The contamination is completely eliminated, not just covered up. Your property value stays protected, and you avoid the costly mistakes that come from attempting this type of cleanup without proper equipment and training.
We at Green Island Group have been handling sewage emergencies across New York City for years. We understand the unique challenges NYC properties present – from aging infrastructure in older Manhattan buildings to the high water tables that make Brooklyn and Queens basements particularly vulnerable to sewage backup issues.
Our team knows how to navigate the complexities of apartment buildings where sewage sources can be difficult to trace. We’re familiar with NYC’s building codes and work within all local regulations while getting you back to normal as quickly as possible.
When other companies see a messy situation and hesitate, we see a problem we’ve solved hundreds of times before. That experience makes all the difference when your property and health are on the line.
First, our certified technicians arrive with industrial-grade equipment – not basic shop vacuums. We assess the contamination level and immediately begin containment to prevent the spread of bacteria and viruses throughout your property.
Next, we extract all standing sewage water and contaminated materials using specialized water extraction equipment designed for biohazard removal. Our team follows strict safety protocols to protect both your property and our workers. We identify and remove any porous materials that can’t be properly sanitized.
Then comes the critical structural drying phase. We deploy industrial dehumidifiers, air movers, and moisture meters to eliminate every trace of moisture from affected areas. This isn’t just about removing visible water – it’s about preventing the mold growth that can start within 24-48 hours in NYC’s humid climate.
Finally, we complete thorough deodorization and restore damaged areas to their original condition. This includes replacing materials that couldn’t be salvaged, sanitizing all surfaces, and ensuring your property is safe for occupancy. Throughout the entire process, we document everything for your insurance claim.

Our comprehensive sewage cleanup service includes emergency water extraction, structural drying, complete deodorization, and full restoration work. We handle everything from minor toilet overflows to major sewer line backups that affect multiple floors or units in NYC buildings.
In New York City, sewage backups often stem from the city’s aging infrastructure. Many buildings have plumbing systems installed decades ago that are more prone to failure. Tree root intrusion into old sewer lines is particularly common in older NYC neighborhoods. Combined with our high water table and the complexity of multi-unit buildings, sewage problems can quickly escalate if not handled properly.
We’re specifically equipped to handle the challenges NYC properties present. Our team understands how water and sewage can travel through older building systems, and we have the advanced tools to trace contamination sources even in complex apartment buildings. We also work directly with insurance companies to streamline your claim process, often billing them directly to reduce your upfront costs and paperwork headaches.
You should call immediately – sewage backups are considered emergencies because the water contains viruses, bacteria, and other dangerous microbes that cause serious illnesses. Every hour you wait increases both health risks and property damage exponentially.
Within the first 24-48 hours, mold can begin growing in affected areas. The longer sewage sits, the deeper it penetrates into flooring, walls, and building materials, making cleanup more extensive and expensive. In NYC’s humid climate and densely packed buildings, this timeline can be even shorter.
Don’t attempt to handle sewage cleanup yourself. The health risks are too serious, and you likely don’t have the proper equipment or training to safely remove contamination and prevent cross-contamination to unaffected areas of your property.
Sewage contains dangerous pathogens that regular water doesn’t. This contaminated water is classified as “black water” – the most dangerous category of water damage that requires specialized equipment, training, and safety protocols to handle safely.
Unlike clean water damage, sewage cleanup requires complete removal and disposal of porous materials like carpeting, padding, and drywall that can’t be properly sanitized. The entire affected area must be thoroughly disinfected using EPA-approved antimicrobials specifically designed for sewage contamination.
Our technicians wear full protective equipment and follow strict containment procedures to prevent spreading contamination to clean areas of your property. We also use specialized air filtration systems during cleanup to protect indoor air quality throughout the restoration process.
Most homeowner’s insurance policies cover sudden and accidental sewage backups, but coverage varies significantly by policy and the specific cause of the backup. We work directly with insurance companies and can often bill them directly, reducing your upfront costs considerably.
The key is documenting everything properly from the very start. Our team photographs all damage, maintains detailed records of our cleanup process, and provides the comprehensive documentation your insurance company needs to process your claim quickly and favorably.
We’ve helped hundreds of NYC property owners navigate insurance claims for sewage damage. Our experience with local insurance practices means we know exactly what documentation they require and how to present your claim for the best possible outcome.
Apartment building sewage cleanup requires special coordination because contamination can affect multiple units through shared plumbing systems. We work closely with building management to identify the source, contain the spread, and restore all affected areas while minimizing disruption to other tenants.
Our team understands NYC building layouts and how sewage can travel through shared plumbing systems, especially in older buildings. We use advanced moisture detection equipment to identify all affected areas, even those that aren’t immediately visible, like behind walls or in adjacent units below the source.
We coordinate extensively with building management on access schedules, containment procedures, and restoration timelines. Our goal is to resolve the emergency quickly while ensuring all affected areas are properly cleaned and restored to prevent future problems that could impact the entire building.
First, ensure your safety – avoid all contact with the sewage and keep children and pets completely away from the affected area. Turn off electricity to affected areas if you can do so safely, but never enter standing water to reach electrical panels or outlets.
If possible, try to stop the source of the backup by locating the main sewer cleanout or shutoff valve. However, don’t attempt any repairs yourself – this is definitely a job for professionals with proper equipment and extensive training in biohazard handling.
Call us immediately for emergency response. While you wait for our arrival, document the damage with photos and videos for insurance purposes, but don’t attempt any cleanup yourself. The health risks are too serious, and improper cleanup can actually spread contamination to previously unaffected areas of your property.
The timeline depends on the extent of contamination, but most residential sewage cleanup projects take 3-7 days from start to finish. Emergency water extraction and initial contamination removal typically happen within hours of our arrival at your property.
Structural drying usually takes 2-4 days, depending on the materials affected and NYC’s humidity levels. We continuously monitor moisture levels throughout the process and won’t declare the job complete until all affected materials are thoroughly dry and properly sanitized according to industry standards.
Restoration work – replacing materials that couldn’t be salvaged – can add additional time depending on the scope of damage. Throughout the entire process, we keep you fully informed of our progress and timeline, and we work efficiently to get you back to normal as quickly as possible while ensuring the job is done right.
