Green Island Group has been serving Syosset and Nassau County homeowners for years. We understand the unique challenges Long Island properties face, from older sewer systems to the impact of harsh winters on plumbing infrastructure.
Our technicians live and work in this community. When your neighbor in Syosset calls us at 2 AM with a sewage emergency, we’re there within the hour. That’s not just good business—it’s how neighbors help neighbors.
You’re not getting a corporate call center or technicians unfamiliar with Nassau County’s building codes and insurance requirements. You’re getting local professionals who’ve handled hundreds of sewage cleanups right here in Syosset.
First, we assess the situation and contain the contamination. Our team identifies the source, measures the extent of damage, and develops a plan that prioritizes your safety. We document everything for insurance purposes while setting up containment barriers.
Next comes extraction and removal. Using powerful truck-mounted pumps and specialized vacuum systems, we remove all sewage and contaminated water. This isn’t a shop vacuum job—we’re talking about industrial equipment designed specifically for hazardous waste removal.
Finally, we sanitize and restore. Every surface gets treated with hospital-grade disinfectants. We use advanced drying techniques to eliminate moisture that could lead to mold growth. The goal isn’t just clean—it’s safe for your family to return home.

Sewage cleanup in Syosset requires more than just removing waste. Nassau County’s climate and older home construction create specific challenges that generic restoration companies miss. High humidity levels mean moisture can hide in walls and subflooring, creating perfect conditions for mold growth weeks later.
We provide structural drying using commercial-grade dehumidifiers and air movers positioned strategically throughout your property. Our moisture detection equipment finds hidden water damage that could cause problems months down the road. This thorough approach prevents the callbacks and recurring issues you’ll get with less experienced companies.
Long Island homeowners also face unique insurance considerations. We work directly with your insurance company, providing detailed documentation and communicating with adjusters who handle Nassau County claims regularly. This local knowledge often means faster claim processing and better coverage for restoration costs.
We provide 24/7 emergency response and typically arrive within 60 minutes of your call to Syosset properties. Sewage emergencies can’t wait—bacteria multiply rapidly, and property damage worsens with each passing hour.
Our local Nassau County location means we’re never more than a short drive from your Syosset home. We keep fully equipped trucks ready around the clock, stocked with everything needed for immediate containment and extraction. When you call our emergency line at 631-256-5711, you’re speaking directly with our dispatch team, not a call center in another state.
Time matters with sewage backups. The sooner we can contain the contamination and begin extraction, the less damage to your property and the lower your restoration costs. We’ve built our entire operation around rapid response because we know how critical those first few hours are.
Raw sewage contains dangerous bacteria, viruses, and parasites that can cause serious illness, including Hepatitis A, E. coli, and Giardia. Children, elderly family members, and anyone with compromised immune systems face the highest risk of infection from exposure.
The contamination isn’t limited to direct contact. Airborne particles can spread throughout your home through your HVAC system, contaminating areas that never had direct sewage contact. Even after visible sewage is removed, harmful microorganisms can survive on surfaces for days or weeks without proper disinfection.
This is why we use hospital-grade disinfectants and follow strict safety protocols during cleanup. Our technicians wear full protective equipment and treat every sewage emergency as a biohazard situation. We don’t just clean what you can see—we eliminate the invisible threats that could make your family sick long after the emergency seems resolved.
Most homeowner’s insurance policies in Nassau County include sewage backup coverage, but the specifics vary significantly between carriers and policy types. Coverage typically depends on the cause of the backup and whether you have specific sewage backup endorsements on your policy.
We work directly with insurance companies and understand the documentation requirements for successful claims. Our team photographs all damage, provides detailed scope reports, and communicates directly with adjusters to ensure you receive the coverage you’re entitled to. We’ve helped hundreds of Syosset homeowners navigate the insurance process successfully.
The key is acting quickly and using a restoration company that understands insurance requirements. Delays in professional cleanup or inadequate documentation can lead to claim denials or reduced payouts. We handle the insurance paperwork so you can focus on getting your family back to normal.
Attempting DIY sewage cleanup puts your health at serious risk and often leads to much higher costs down the road. Raw sewage contains pathogens that require specialized equipment and disinfectants to eliminate safely. Without proper protective gear and training, you’re exposing yourself and your family to dangerous bacteria and viruses.
Home cleaning products aren’t designed for biohazard cleanup. Even bleach solutions, while helpful for surface disinfection, can’t penetrate porous materials like drywall and subflooring where bacteria can hide and multiply. Professional-grade antimicrobial treatments and specialized drying equipment are necessary to prevent ongoing contamination and mold growth.
Insurance companies also prefer professional cleanup for sewage emergencies. DIY attempts can actually void coverage if not done according to industry standards. The money you think you’re saving upfront often gets spent multiple times over dealing with recurring odors, mold problems, and health issues that professional cleanup would have prevented.
Permanent odor elimination requires more than just masking smells with air fresheners or ozone treatments. Sewage odors come from bacteria and organic compounds that have penetrated porous materials throughout your property. Surface cleaning won’t reach these embedded sources of contamination.
We use a multi-step approach that includes antimicrobial treatments, specialized deodorization compounds, and complete removal of contaminated materials when necessary. Our equipment includes hydroxyl generators and thermal fogging systems that neutralize odor molecules at the molecular level, not just cover them up.
The key is treating the source, not just the symptom. If sewage has soaked into subflooring, drywall, or insulation, those materials often need replacement rather than cleaning. We identify all contaminated materials during our initial assessment and recommend the most effective treatment for permanent odor elimination. Half-measures lead to recurring problems and customer callbacks—something we avoid through thorough initial treatment.
Tree root intrusion is the leading cause of sewage backups in Nassau County, especially in Syosset’s established neighborhoods with mature trees. Roots seek out moisture and can infiltrate even small cracks in sewer lines, eventually growing large enough to cause complete blockages. This problem worsens during Long Island’s wet spring seasons when root growth accelerates.
Aging sewer infrastructure also contributes to backup problems. Many Syosset homes were built decades ago with clay or cast iron sewer lines that deteriorate over time. These older pipes are more susceptible to root intrusion, settling, and blockages from grease and debris buildup.
Heavy rainfall can overwhelm municipal sewer systems, causing backups through floor drains and basement fixtures. Nassau County’s flat topography and high water table make some areas particularly vulnerable during storm events. Regular maintenance and sewer line inspections can help identify potential problems before they become expensive emergencies, but when backups do occur, professional cleanup is essential to prevent health hazards and property damage.
