NYS and NYC M/WBE Certified Contractor
When sewage backup strikes, you need more than just cleanup—you need complete restoration. We eliminate every trace of contamination, neutralize dangerous bacteria and viruses, and get your property back to the way it was before the disaster.
You won’t have to worry about lingering odors, hidden moisture, or health risks. Our specialized equipment and trained technicians handle everything from water extraction to structural drying, so you can focus on getting back to normal.
The difference is in the details. While others might miss contaminated areas or rush through deodorization, we methodically sanitize every surface and use advanced drying techniques to prevent mold growth and structural damage.
Green Island Group has been serving Nassau County families and businesses with professional restoration services when they need it most. We understand the unique challenges that Long Island properties face, from aging sewer systems to the area’s high water table that can complicate sewage backup situations.
Our team knows Malverne’s infrastructure and the common causes of sewage problems in this community. We’ve helped countless neighbors restore their properties after sewage backups, and we’ve built our reputation on doing the job right the first time.
When you call us, you’re working with restoration professionals who live and work in this area. We’re not a national chain—we’re your neighbors, and we treat every property like it’s our own.
First, we secure the area and assess the extent of contamination. Our technicians arrive with full protective equipment and powerful extraction units to remove standing sewage water immediately. Time matters here—the longer contaminated water sits, the more damage it causes.
Next comes the critical sanitization phase. We use EPA-approved disinfectants to eliminate bacteria, viruses, and other pathogens that make sewage so dangerous. Every affected surface gets thoroughly cleaned and sanitized, not just the obvious areas.
Finally, we dry and deodorize the space using industrial-grade equipment. Our structural drying process prevents mold growth and eliminates moisture trapped in walls, floors, and other materials. We don’t consider the job done until your property is completely restored and safe for your family.

In Nassau County, sewage backups often result from aging infrastructure, tree root intrusion, or heavy rainfall overwhelming local systems. These situations require specialized knowledge and equipment that most homeowners don’t have access to. We bring industrial-grade tools and EPA-approved sanitizers to every job.
You’ll also get direct insurance billing when possible, so you don’t have to handle the paperwork during an already stressful time. Our team works with major insurance companies throughout Long Island and understands the documentation they require for sewage backup claims.
We provide 24/7 emergency response throughout Nassau County, typically arriving within an hour of your call. Sewage backups require immediate attention because contaminated water poses serious health risks and causes more damage the longer it sits.
Our emergency crews are always on standby with fully equipped trucks ready to handle sewage extraction and initial sanitization. We understand that sewage emergencies don’t happen on a schedule, which is why we maintain round-the-clock availability for Malverne residents.

Raw sewage contains dangerous bacteria, viruses, and parasites that can cause serious illness through direct contact or inhalation. Common health risks include gastroenteritis, hepatitis A, salmonellosis, and other infections that can be particularly dangerous for children and elderly family members.
The contamination isn’t just in the visible sewage—harmful microorganisms can become airborne and settle on surfaces throughout your home. This is why professional cleanup with proper protective equipment and EPA-approved disinfectants is essential, not optional.
Attempting to clean sewage backup yourself puts your family at risk and often spreads contamination to other areas of your home. Our technicians wear full protective gear and follow strict protocols to eliminate health hazards completely, ensuring your home is safe for your family to return.
Most homeowner’s insurance policies in New York cover sewage backup cleanup, but coverage depends on the cause and your specific policy details. We work directly with insurance companies throughout Nassau County and can help determine your coverage before starting work.
The key is documenting everything properly and acting quickly. Take photos of the damage and contact your insurance company immediately, but don’t wait for approval to start cleanup—sewage contamination becomes more dangerous and expensive to remediate with each passing hour.
We handle insurance paperwork and can bill your insurance company directly in many cases, removing that stress from your shoulders. Our team knows exactly what documentation insurance adjusters require and ensures everything is properly recorded for your claim.
Sewage odors aren’t just unpleasant—they indicate the presence of harmful bacteria and gases that pose health risks. We use a multi-step deodorization process that eliminates odors at the source rather than just masking them with air fresheners.
First, we remove all contaminated materials that can’t be properly sanitized. Then we apply specialized enzyme treatments that break down organic matter causing odors. Finally, we use ozone generators and air scrubbers with activated charcoal filters to neutralize any remaining odor molecules.
The process takes time because we’re not just covering up smells—we’re eliminating the bacteria and organic compounds that create them. Many companies rush this step, leaving customers with lingering odors that return after a few days. We don’t consider the job complete until your home smells completely normal.
In Malverne and throughout Nassau County, sewage backups typically result from tree root intrusion into aging sewer lines, blockages from grease and debris, or municipal system overflows during heavy rainfall. The area’s mature trees are beautiful, but their roots naturally seek out moisture in sewer pipes.
Many homes in our area have older sewer connections that develop small cracks over time, allowing roots to enter and eventually block the line. Heavy rains can also overwhelm local systems, causing backups through floor drains and toilets in lower levels of homes.
We’ve seen every type of sewage backup situation in Malverne and can often identify the cause during our initial assessment. While we focus on cleanup and restoration, we can also recommend preventive measures and refer you to trusted plumbers for permanent repairs to prevent future backups.
Most sewage cleanup projects in Malverne take 3-5 days from start to finish, depending on the extent of contamination and affected materials. Emergency water extraction and initial sanitization happen on day one, followed by structural drying and final restoration work.
The timeline depends on several factors: how much area was affected, what materials were contaminated, and how quickly we can get moisture levels back to normal. We use moisture meters to track progress and don’t rush the drying process—doing it right prevents mold problems later.
We’ll give you a realistic timeline during our initial assessment and keep you updated throughout the process. Some companies promise unrealistic completion times, but proper sewage cleanup can’t be rushed without compromising your family’s safety and your property’s long-term condition.
