NYS and NYC M/WBE Certified Contractor
Water damage doesn’t just create puddles on your floor. It weakens building structures, breeds toxic mold, and turns a manageable problem into a financial disaster if you wait even 24 hours.
When you call Green Island Group, you get immediate action that stops damage cold. Our certified technicians arrive with industrial-grade equipment—not basic shop vacuums. We extract standing water, hunt down hidden moisture in walls and subfloors, and begin professional drying before mold spores have a chance to multiply.
Your Manhattan property gets restored to its original condition. You get your peace of mind back, knowing the job was handled by professionals who understand NYC buildings inside and out.
We’ve been handling water emergencies across Manhattan for years. We understand challenges that make NYC water damage unique—aging infrastructure in pre-war buildings, high water tables that flood basements, and apartment layouts where water travels between units through hidden pathways.
Our team knows how to trace water sources in complex Manhattan buildings where a leak on the 8th floor can damage apartments three floors below. We’re fully licensed and follow all NYS, NYC, and EPA regulations for safe, compliant restoration work.
Manhattan property owners choose us because we deliver results that insurance companies approve and neighbors can’t even detect. Your emergency becomes our priority, and we don’t leave until your space is completely restored.
First, we respond within one hour. Our emergency team arrives with industrial pumps, moisture detection equipment, and everything needed to stop water damage immediately. We assess the situation, secure the area, and begin water extraction right away.
Next, we eliminate every drop of moisture. Using professional-grade dehumidifiers, air movers, and precision moisture meters, we dry affected areas completely. We don’t guess—we monitor humidity levels and moisture content until readings confirm your property is bone dry.
Finally, we rebuild what water damaged. From replacing soggy drywall to refinishing warped hardwood floors, we handle reconstruction that returns your space to pre-damage condition. We also coordinate directly with your insurance company, managing paperwork and documentation so you can focus on getting back to normal.

Manhattan’s environment creates perfect conditions for water damage disasters. Summer humidity allows mold to explode within 48 hours. Older building materials like plaster walls and wood floors absorb water like sponges and take weeks to dry without professional equipment.
Our comprehensive flood damage restoration includes emergency water extraction, structural drying, mold prevention treatments, and complete reconstruction services. We handle everything from burst heating pipes in co-op buildings to storm flooding in ground-floor retail spaces.
We’re available around the clock because water emergencies don’t respect business hours. Whether a frozen pipe bursts at 3 AM or your basement floods during a weekend storm, our Manhattan-based team responds immediately to minimize damage and begin the restoration process that gets your life back on track.
We guarantee response within one hour of your call, 24 hours a day, every day of the year. Water damage spreads exponentially in Manhattan’s older buildings where porous materials absorb moisture rapidly and structural elements can be damaged within hours.
Our rapid response team arrives fully equipped with industrial water extraction pumps and begins removing standing water immediately. The faster we can extract water and start the drying process, the less structural damage your property will sustain and the lower your total restoration costs will be.
Speed matters because mold begins growing within 24-48 hours in Manhattan’s humid climate. Our immediate response prevents secondary damage that could multiply your restoration costs and create health hazards for building occupants.
Yes, we manage your entire insurance claim from initial documentation through final approval. We bill your insurance company directly and handle all communication with adjusters, eliminating the paperwork headache during an already stressful situation.
Our team creates detailed damage assessments, photographic evidence, and restoration reports that insurance companies require for claim processing. We’ve worked with every major carrier and understand exactly what documentation they need for fastest claim approval.
This full-service approach means you get professional restoration without upfront costs, and you don’t waste time learning insurance procedures. We handle the bureaucracy so you can focus on getting your property and your life back to normal.
Manhattan’s unique building characteristics create restoration challenges you won’t find elsewhere. Pre-war buildings have aging plumbing systems that fail unpredictably, and water can travel through multiple apartments via shared walls and utility chases, making damage assessment complex.
Our team specializes in NYC building codes and restoration regulations. We understand how water behaves in different Manhattan construction types, from brownstone basements to high-rise apartment towers. We’re licensed for all required NYC restoration procedures and follow EPA protocols for safe remediation.
Manhattan’s coastal location increases storm flood risk, while dense urban development creates humidity pockets that accelerate mold growth. We use specialized equipment and techniques specifically designed for these environmental challenges that generic restoration companies aren’t equipped to handle.
Restoration timeline depends on water volume, contamination level, and materials affected. Minor leaks affecting single rooms typically require 3-5 days for complete drying and repair, while major flooding can take several weeks for full restoration.
Professional drying alone takes 3-7 days depending on humidity levels and water absorption. Manhattan’s older building materials like horsehair plaster and hardwood floors retain moisture longer than modern construction and require extended drying time to prevent future problems.
After complete drying, reconstruction begins and can range from same-day repairs for minor damage to several weeks for extensive rebuilding. We provide realistic timelines after thorough damage assessment and update you daily on progress throughout the restoration process.
We prevent mold growth through immediate professional intervention and complete moisture elimination—the only proven method for mold prevention. Our industrial dehumidifiers, air circulation systems, and precision moisture monitoring ensure affected materials reach safe moisture levels.
Our process includes continuous moisture monitoring throughout drying and antimicrobial treatment of affected surfaces when appropriate. We don’t consider restoration complete until moisture readings confirm materials are at levels that prevent microbial growth.
Manhattan’s humid climate makes professional mold prevention critical because spores can begin multiplying within 24-48 hours in moist environments. DIY drying methods simply can’t achieve the thorough moisture elimination necessary to prevent mold problems that could cost thousands more to remediate later.
Ensure safety first by shutting off electricity to flooded areas if you can reach the breaker safely—never walk through standing water with power on. Stop the water source if possible by closing the main water valve or isolating the leak.
Document everything immediately with photos and videos for insurance purposes, but don’t delay calling for professional help. Move valuable items and electronics away from water if you can do so safely, but don’t risk injury attempting to save belongings.
Call us immediately at the first sign of water intrusion. Every hour of delay allows water to penetrate deeper into building materials, spread to unaffected areas, and increase restoration costs exponentially. Professional water extraction must begin within hours to prevent catastrophic damage and toxic mold growth.
