NYS and NYC M/WBE Certified Contractor
You get more than cleanup—you get your life back. Your basement becomes usable again instead of a contaminated mess you can’t enter. The smell disappears completely, not just temporarily masked. Your family can return home safely without worrying about invisible health threats.
Most importantly, you avoid the nightmare scenarios that happen when sewage cleanup is done wrong. No lingering odors that return weeks later. No hidden moisture that turns into expensive mold problems. No structural damage that could have been prevented with proper drying.
We handle everything from the initial emergency response through complete restoration, so you’re not juggling multiple contractors or wondering if the job was done right.
Green Island Group has been helping Nassau County homeowners recover from water and sewage emergencies for years. We understand the unique challenges Long Island properties face—from aging sewer infrastructure in older Massapequa neighborhoods to basement flooding from the area’s high water table.
Our local presence means faster response times when you’re dealing with a sewage emergency. We’re not a national chain trying to figure out your area—we live and work here, and we know exactly what Massapequa residents are dealing with when their sewer lines fail.
First, we secure the area and assess the contamination level to determine the safest approach. Our certified technicians arrive with specialized protective equipment and industrial-grade tools designed specifically for sewage cleanup.
Next comes complete water extraction using powerful pumps and vacuums that remove all standing sewage water. We don’t just get the obvious puddles—we extract moisture from carpets, padding, and porous materials that could harbor dangerous bacteria.
Then we begin structural drying with commercial dehumidifiers and air movers positioned strategically throughout the affected areas. This prevents mold growth and ensures moisture doesn’t remain trapped in walls, floors, or subflooring. Finally, we apply professional-grade antimicrobial treatments and deodorization to eliminate pathogens and completely remove sewage odors.

Your sewage cleanup service includes immediate water extraction, complete structural drying, antimicrobial treatment, and professional deodorization. We also handle any necessary repairs to damaged drywall, flooring, or other materials that can’t be salvaged.
In Nassau County, sewage backups often result from aging infrastructure and heavy rainfall overwhelming storm systems. That’s why our service goes beyond basic cleanup. We help you understand what caused the backup and provide recommendations to prevent future incidents.
We work directly with your insurance company to streamline the claims process. You won’t be stuck paying out of pocket while waiting for reimbursement, and you won’t have to navigate insurance paperwork while dealing with the stress of sewage damage.
We provide 24/7 emergency response throughout Massapequa and Nassau County, typically arriving within one hour of your call. Speed is critical with sewage backups because contaminated water poses immediate health risks and causes more damage the longer it sits.
Our local presence means we’re not traveling from distant locations when you have an emergency. We maintain equipment and crews ready to respond immediately, even during nights, weekends, and holidays when most sewage backups seem to happen.
Sewage contains dangerous pathogens, bacteria, and viruses that can cause serious illness through direct contact or breathing contaminated air. The dark, thick water from sewer backups is classified as Category 3 water damage—the most hazardous type.
Even after the visible water is gone, harmful microorganisms can remain in porous materials like drywall, insulation, and carpeting. That’s why professional cleanup with antimicrobial treatment is essential. You can’t simply mop up sewage water and consider the area safe.
Children, elderly family members, and anyone with compromised immune systems face higher risks from sewage exposure, making immediate professional cleanup even more important.
Most homeowner’s insurance policies cover sudden and accidental sewage backups, but coverage varies significantly between policies. We work directly with insurance companies and can help you understand your specific coverage during the initial assessment.
We handle all insurance documentation and can bill your insurance company directly in many cases, so you’re not paying large amounts upfront. Our experience with insurance claims means we know exactly what documentation they require and how to present the scope of work for fastest approval.
If your policy doesn’t cover sewage backup, we offer transparent pricing and can discuss payment options to ensure you get the professional cleanup your family’s health requires.
Complete odor elimination requires removing the source of contamination, not just masking the smell. We start with thorough extraction of all sewage water and contaminated materials that can’t be properly sanitized.
Next, we apply professional-grade antimicrobial treatments that kill odor-causing bacteria at the source. Our industrial deodorization equipment uses hydroxyl generators and ozone treatment to neutralize odor molecules in the air and on surfaces.
The key difference from DIY approaches is addressing hidden contamination. Sewage can seep into subflooring, wall cavities, and other areas where standard cleaning can’t reach. Our moisture detection equipment identifies all affected areas so nothing gets missed that could cause odors to return later.
Nassau County’s aging sewer infrastructure is a major factor, especially in older Massapequa neighborhoods where sewer lines may be 50+ years old. These pipes crack and collapse over time, creating blockages that cause backups into homes.
Heavy rainfall overwhelms the area’s storm sewer systems, which can cause municipal sewage to back up through floor drains and toilets. Long Island’s high water table also makes basement flooding more likely during storms.
Tree roots are another common culprit, growing into sewer lines through small cracks and eventually creating major blockages. Even roots from trees not on your property can affect the main sewer lines that serve your home.
Emergency cleanup and water extraction typically takes 4-8 hours depending on the amount of sewage and affected area size. However, complete drying and restoration usually requires 3-5 days to ensure all moisture is removed and prevent mold growth.
The timeline depends on several factors: the extent of contamination, what materials need removal versus cleaning, and humidity levels that affect drying time. We use moisture meters to confirm everything is completely dry before considering the job complete.
We’ll keep you informed throughout the process and can often arrange temporary housing assistance through your insurance if your home isn’t habitable during restoration. Our goal is getting your family back home safely as quickly as possible while ensuring the job is done right.
