NYS and NYC M/WBE Certified Contractor
You get your space back the way it was before the flood hit. Not just dried out, but actually restored with materials that can handle whatever Manhattan’s weather throws at it next.
The difference isn’t just in the equipment we bring or how fast we show up. It’s in understanding that your property needs to work for your life, not just pass an inspection. When we’re done, you’re not wondering if problems will surface later.
Your floors, walls, and belongings get the kind of attention that prevents the mold, warping, and structural issues that turn a flood into a years-long headache.
Green Island Group has restored over 5,000 properties across New York State, including countless Manhattan buildings that face unique flooding risks. We understand how water moves through pre-war buildings, why basement apartments flood so quickly, and what it takes to properly dry spaces in this coastal climate.
Manhattan’s aging infrastructure and high water table create flooding situations you won’t find in other cities. We’ve seen the September 2023 floods that dumped over 6 inches of rain on Midtown in hours. We know which neighborhoods flood first and why.
This isn’t guesswork for us. It’s experience earned through thousands of emergency calls across Manhattan’s diverse building types and flood-prone areas.
You call, we’re typically at your door within 2-4 hours, even during major flood events. Our first priority is stopping additional damage by extracting standing water and identifying moisture that’s hidden in walls, floors, and structural elements.
We use industrial-grade equipment including thermal imaging to find water you can’t see. Then comes the systematic drying process using commercial dehumidifiers and air movers positioned based on your building’s specific layout and airflow patterns.
Throughout the process, we document everything for your insurance claim while handling the paperwork directly with your carrier. You get detailed photos, moisture readings, and a complete scope of work that insurance companies actually approve.
The final step is restoration using materials chosen specifically for Manhattan’s coastal climate conditions, not generic replacements that might fail when the next storm hits.

Your flood restoration includes water extraction, structural drying, mold prevention, debris removal, and complete reconstruction when needed. We handle everything from emergency water removal to replacing damaged flooring, drywall, and mechanical systems.
Manhattan properties face specific challenges that require specialized approaches. The city’s high water table means basement flooding often involves contaminated water. Our IICRC-certified technicians follow NYS, NYC, and EPA protocols for safe cleanup and proper disposal.
We also understand Manhattan’s building codes and permit requirements. When reconstruction is needed, we handle the regulatory compliance so your property meets current standards. This includes proper moisture barriers, upgraded electrical systems, and flood-resistant materials where required.
Your service includes direct insurance billing, detailed damage documentation, and project management from emergency response through final inspection.
We provide 24/7 emergency response throughout Manhattan and typically arrive within 2-4 hours of your call, even during major storm events. Time is critical after flood damage because every hour of delay increases the risk of secondary damage like mold growth or structural deterioration.
Our rapid response team is specifically equipped for Manhattan’s flood patterns and building types. We keep crews staged during weather events and maintain emergency supplies year-round so we can mobilize immediately when you need us.
Fast response isn’t just about convenience. It’s about protecting your property value and preventing a manageable flood cleanup from becoming a major reconstruction project that costs tens of thousands more.
Manhattan’s unique challenges include aging infrastructure, high water tables, and dense urban development that creates specific flooding patterns. Many buildings have basement apartments that flood quickly, and water can travel through multiple units making source identification difficult.
The city’s coastal location increases storm surge risks, while the high water table means basement flooding often involves contaminated water requiring specialized cleanup protocols. Manhattan’s building codes also require specific procedures for restoration work in flood-prone areas.
Our team understands these local challenges and follows all NYS, NYC, and EPA regulations for proper restoration and safety. We know which neighborhoods flood first, how water moves through different building types, and what materials work best in this coastal climate.
Yes, we handle insurance paperwork and bill your carrier directly in most cases. We provide detailed documentation including photos, moisture readings, and itemized scopes of work that insurance companies need to process claims efficiently.
Our experience with thousands of restoration projects means we know exactly what documentation insurers require and how to present damage assessments that get approved quickly. We also understand the specific coverage issues that come up with Manhattan properties.
We reach out to your insurance company within 24 hours to ensure claims are handled promptly, and we work directly with adjusters throughout the restoration process. This removes the stress of dealing with insurance paperwork while you’re dealing with flood damage.
Mold prevention requires immediate action and thorough drying using industrial-grade equipment. We use commercial dehumidifiers, air movers, and moisture meters to ensure all affected materials are completely dried within the critical 24-48 hour window before mold can establish.
Manhattan’s coastal humidity makes proper drying even more critical. We monitor moisture levels in walls, floors, and structural elements using thermal imaging to detect hidden water that standard methods miss. All affected areas receive antimicrobial treatment as part of our standard protocol.
If we find existing mold during the restoration process, our certified technicians can handle remediation following EPA guidelines. The key is acting fast and using the right equipment and techniques, which is why our rapid response time is so important for Manhattan properties.
We handle all types of flood damage including storm surge, burst pipes, sewer backups, appliance leaks, and basement flooding from high water tables. Each type requires different cleanup approaches, especially in Manhattan where contaminated water and structural complexity are common factors.
Our services include water extraction, structural drying, debris removal, mold prevention, and complete reconstruction when needed. We restore residential and commercial properties, from small apartments to large office buildings, using materials and techniques specifically chosen for Manhattan’s building types and climate.
We also handle the specialized cleanup required for contaminated water situations, which are common in Manhattan basement floods. Our technicians are trained in proper safety protocols and use professional-grade equipment for safe, thorough restoration.
Flood restoration costs vary significantly based on the extent of damage, type of water involved, and size of the affected area. Minor water damage might cost a few thousand dollars, while major flooding requiring reconstruction can reach tens of thousands.
Manhattan’s higher costs for labor, materials, and permits do affect restoration pricing compared to other areas. However, acting quickly often reduces overall costs by preventing secondary damage that requires more extensive repairs later.
We provide detailed estimates after assessing your specific situation and work directly with insurance companies to maximize your coverage. Many flood restoration costs are covered by insurance, and we handle the claims process to ensure you get the benefits you’re entitled to receive.
