NYS and NYC M/WBE Certified Contractor
When sewage backup strikes your Corona property, you’re not just dealing with a mess—you’re facing serious health hazards and potential structural damage. Raw sewage contains dangerous bacteria, viruses, and pathogens that can contaminate everything they touch.
You get your property back to a safe, livable condition. We extract all contaminated water, sanitize affected surfaces, and eliminate lingering odors that remind you this ever happened. Your family can return to a home that’s not just clean, but genuinely safe.
The difference is in the details. While others might remove visible sewage and call it done, we use industrial-grade equipment to find hidden moisture, prevent mold growth, and restore your property to pre-damage condition.
Green Island Group has been handling sewage emergencies across Queens for years. We understand the unique challenges Corona homeowners face—from aging infrastructure to the area’s susceptibility to sewer backups during heavy rainfall.
You’re working with technicians who’ve seen it all in Queens neighborhoods. We know which areas flood first, how Corona’s sewer systems behave, and exactly what it takes to get your property back to normal.
We’re not just another restoration company. We’re your neighbors who happen to be really good at cleaning up sewage disasters and getting your life back on track.
First, we assess the damage and identify all affected areas. This isn’t just about what you can see—sewage can seep into places you’d never think to check. We map out the full extent of contamination before we start.
Next comes extraction and removal. We use powerful truck-mounted equipment to remove all standing sewage and contaminated water. Hidden moisture gets pulled from walls, floors, and subfloors using specialized extraction tools.
Finally, we sanitize and deodorize everything. Every surface gets treated with professional-grade disinfectants that kill bacteria and viruses. We don’t just mask odors—we eliminate them completely using advanced deodorization techniques.

Your sewage cleanup includes water extraction, structural drying, complete sanitization, and professional deodorization. We also handle minor repairs caused by the backup and work directly with your insurance company to streamline the claims process.
Corona’s aging sewer infrastructure makes sewage backups more common than in newer developments. The neighborhood’s location in Queens means we often see backups caused by tree root intrusion and improper waste disposal—two of the most common causes of sewer problems in this area.
We coordinate with your insurance company from day one. Most Corona homeowners find their sewage cleanup is covered under their policy, and we handle the paperwork to minimize your out-of-pocket costs and stress.
We provide 24/7 emergency response throughout Corona and can typically arrive within an hour of your call. Sewage backup is a health emergency, not just a cleanup issue—the longer contaminated water sits, the more damage it causes and the higher the health risks become.
Our trucks are equipped and ready to go at all hours because we know sewage doesn’t wait for business hours. When you call, you’re talking to our dispatch team who can give you an accurate arrival time and start coordinating with your insurance company immediately.
The faster we respond, the less damage you’ll face and the lower your overall restoration costs will be.
Raw sewage contains harmful bacteria, viruses, and pathogens including E. coli, Salmonella, and Hepatitis A. Direct contact can cause serious illness, and even breathing air in contaminated areas poses health risks, especially to children and elderly family members.
Sewage contamination isn’t something you can clean with household products. The bacteria and viruses require professional-grade disinfectants and proper safety equipment to eliminate safely. Even after visible sewage is removed, contamination can remain in porous materials like drywall and flooring.
We follow strict safety protocols and use EPA-approved disinfectants to ensure your Corona home is genuinely safe for your family’s return—not just visually clean.
Most homeowner’s insurance policies cover sudden and accidental sewage backups, but coverage varies depending on the cause and your specific policy. We work directly with insurance companies throughout Queens and can help determine your coverage during our initial assessment.
We handle the insurance coordination from start to finish—documenting damage, providing detailed estimates, and communicating directly with adjusters. This saves you time and often results in better coverage because we know exactly how to present sewage cleanup claims.
If your backup is caused by a city sewer main issue, there may be additional coverage options available through municipal programs. We help navigate these options to minimize your out-of-pocket costs.
Professional deodorization goes far beyond air fresheners or masking agents. We use specialized equipment including ozone generators, hydroxyl generators, and thermal fogging to break down odor-causing molecules at the source rather than just covering them up.
Sewage odors can penetrate porous materials like drywall, insulation, and subflooring. We identify all affected materials and either clean them using professional-grade deodorization techniques or recommend replacement when contamination is too severe to remediate safely.
The process typically takes 24-48 hours after all contaminated materials are cleaned or removed. We don’t consider the job complete until you can walk into your Corona home and smell nothing but clean air.
DIY sewage cleanup is dangerous and often makes the problem worse. Raw sewage requires specialized equipment, professional-grade disinfectants, and safety gear that aren’t available to homeowners. Without proper training, you risk serious illness and incomplete cleanup that leads to mold growth and structural damage.
Insurance companies often require professional cleanup for sewage claims, so DIY attempts can actually cost you more by voiding coverage. Professional cleanup also comes with documentation that proves the work was done to industry standards—something you’ll need for insurance and potential future property sales.
The health risks alone make professional cleanup essential. We have the training, equipment, and experience to handle sewage safely while protecting your family and property.
Most sewage cleanup projects in Corona take 3-5 days from start to finish, but timeline depends on the extent of contamination and affected materials. Emergency water extraction and initial sanitization happen within hours, but complete drying and final restoration can take several days.
Structural drying is the longest phase—we can’t rush this process because hidden moisture leads to mold growth and structural problems later. We use moisture meters to ensure everything is completely dry before moving to final cleaning and any necessary repairs.
We keep you informed throughout the process and can often arrange temporary accommodations through your insurance if your Corona home isn’t habitable during cleanup. Our goal is thorough restoration, not just fast completion.
