NYS and NYC M/WBE Certified Contractor
You sleep soundly knowing every trace of contamination is gone. Not just the stuff you can see – the microscopic bacteria that can make your kids sick weeks later.
Your basement doesn’t smell like a reminder of the worst day of the year. Instead, it’s cleaner than it was before the backup happened. Our industrial sanitization process eliminates pathogens that basic cleaning can’t touch.
The insurance paperwork gets handled without you having to become an expert in coverage policies. You get detailed documentation that maximizes your claim while we handle the back-and-forth with adjusters who know our work.
Green Island Group understands Nassau County’s infrastructure like few companies do. We’ve cleaned up sewage disasters from aging septic systems in Salisbury to overwhelmed municipal lines during nor’easters.
Most of Nassau County’s North Shore still depends on cesspools and septic systems installed decades ago. When these fail – and they do fail – contamination spreads through basements faster than most homeowners realize. We’ve seen what happens when families try to wait it out or handle cleanup themselves.
Our technicians know which neighborhoods flood first during heavy rains and which areas have the oldest sewer connections. This local knowledge means faster diagnosis, better solutions, and restoration that accounts for the specific challenges your property faces.
We arrive fast and assess the contamination level immediately. Our technicians suit up in full protective equipment and begin extraction using pumps designed specifically for sewage removal. This isn’t a shop vacuum from Home Depot – this is industrial equipment that removes contaminated water completely.
Sanitization comes next, and this is where most companies cut corners. We use hospital-grade antimicrobial agents that eliminate bacteria, viruses, and pathogens that survive basic cleaning. Every surface gets treated according to strict protocols that most restoration companies don’t even know exist.
Structural drying runs continuously until moisture levels return to normal. Our equipment monitors humidity and moisture content in real-time. When we’re done, you get documentation showing exactly what was cleaned, what was replaced, and verification that your property meets safety standards for reoccupation.

Your sewage cleanup includes complete water extraction, antimicrobial treatment, structural drying, deodorization, and full documentation for insurance claims. We also handle disposal of contaminated materials according to EPA regulations.
Nassau County’s unique geography creates sewage backup challenges you won’t find elsewhere. The high water table means contamination can spread horizontally through soil and affect areas that seem unconnected to the original backup. Salisbury’s mix of newer developments and older infrastructure means each property requires different approaches.
We stock equipment specifically for Long Island conditions. Our dehumidifiers account for coastal humidity levels. Our extraction pumps handle the fine sand and silt that characterize local soil conditions. Even our antimicrobial treatments are selected for effectiveness in the specific bacterial environments common to Nassau County septic and sewer systems.
We guarantee response within 60 minutes anywhere in Nassau County, including Salisbury. Our trucks are strategically positioned throughout Long Island, and we maintain 24/7 dispatch specifically for sewage emergencies.
Speed matters because sewage contamination doubles in affected area roughly every hour during the first day. What starts as a manageable cleanup in one room becomes a multi-room disaster if you wait. We’ve seen minor toilet backups turn into full basement remediation projects because families waited overnight to call professionals.
Our rapid response includes immediate containment to prevent contamination from spreading to unaffected areas. We arrive with full protective equipment and begin extraction immediately, not after we assess and give you an estimate. Every minute counts when raw sewage is in your home.
Raw sewage carries Hepatitis A, E. coli, Salmonella, Giardia, and dozens of other pathogens that cause severe illness. Children under 10 and adults over 65 face the highest risk, but healthy adults can develop serious infections from even brief exposure.
The contamination becomes airborne within hours. You’re breathing these pathogens even if you’re not touching contaminated surfaces. Symptoms can take days or weeks to appear, which is why many families don’t connect their illness to a sewage backup that happened weeks earlier.
Beyond immediate illness, sewage contamination can trigger long-term respiratory problems and autoimmune responses in sensitive individuals. We always recommend evacuating vulnerable family members immediately and keeping everyone out of affected areas until professional sanitization is complete. The health risks are simply too serious to take chances with DIY cleanup.
Coverage depends on your specific policy and the cause of the backup. Most standard homeowner’s policies exclude sewage backup unless you’ve purchased additional coverage, but many homeowners don’t realize they have this protection through riders or endorsements they forgot about.
We work directly with insurance companies daily and know exactly what documentation they require for maximum coverage. Our detailed reports include moisture readings, contamination levels, photos of all affected areas, and itemized lists of all work performed. This comprehensive approach often results in higher claim payments than families expect.
Even if you don’t have sewage backup coverage, related water damage may still be covered depending on the cause. We’ll review your policy language and work with your adjuster to identify every possible avenue for coverage. Our goal is to minimize your out-of-pocket costs while ensuring the work is done right.
Permanent odor elimination requires removing the source, not just masking the smell. We extract all contaminated materials that can’t be properly sanitized – soaked drywall, insulation, carpeting, and anything else that absorbed sewage.
Next comes antimicrobial treatment that kills odor-causing bacteria at the molecular level. We use professional-grade products that penetrate porous surfaces where bacteria hide. This isn’t something you can buy at a hardware store – these treatments require certification and proper application to be both effective and safe.
Our industrial air scrubbers run continuously during the drying process to remove airborne contaminants and odor molecules. The final step involves specialized deodorization treatments that neutralize any remaining odors. When we’re finished, your property smells completely normal – not like it’s covering up something with air fresheners.
Nassau County’s infrastructure creates perfect conditions for sewage problems. Much of the North Shore, including Salisbury, still relies on septic systems and cesspools installed 30-50 years ago when these areas were first developed. These systems weren’t designed for today’s usage patterns or extreme weather events.
Tree root intrusion is massive here because of our mature landscaping and the way roots seek moisture during dry periods. Roots can travel 50+ feet to find water sources and will exploit even hairline cracks in aging sewer lines. Once they establish themselves, blockages develop quickly.
Heavy rains overwhelm both septic systems and municipal sewers. Nassau County’s flat topography and high water table mean water has nowhere to go during major storms. When the ground becomes saturated, septic systems can’t drain properly and sewage backs up into homes. Municipal systems also struggle during peak flow periods.
DIY sewage cleanup almost always fails and often makes the situation much worse. Consumer equipment can’t remove contamination from porous materials, and household cleaners don’t kill the pathogens that make people sick. You end up with hidden contamination that causes mold growth and ongoing health problems.
The biggest issue is what you can’t see. Sewage soaks into subflooring, wall cavities, and insulation where you can’t reach it with basic tools. Without professional moisture detection equipment, this hidden contamination continues spreading and creates ideal conditions for dangerous mold growth within 24-48 hours.
Professional cleanup also includes proper disposal of contaminated materials according to EPA regulations, something most homeowners don’t realize they’re responsible for. When you factor in health risks, incomplete cleanup, potential mold problems, and regulatory compliance issues, professional restoration actually costs less than attempting DIY cleanup that has to be redone correctly later.
