NYS and NYC M/WBE Certified Contractor
Water damage moves fast. What looks like a wet floor or a damp wall is usually moisture that’s already worked its way into the subfloor, the wall cavity, or the ceiling assembly above you. The EPA confirms mold can begin growing within 24 to 48 hours of water intrusion — and in Great Neck’s older homes, many built in the 1920s through 1950s, that moisture travels further and faster than in modern construction. Plaster walls, aging insulation, and older subfloor materials absorb and hold water in ways that look dry on the surface long before they actually are.
When we handle the job right, you’re not just dealing with what you can see. You’re walking away knowing the moisture has been pulled from inside the structure — not just off the surface — and that nothing was left behind to become a problem three weeks from now. For a home worth over a million dollars in a market where school district quality and property value are deeply connected, that’s not a small thing.
Great Neck’s peninsular position means flooding events here often come from multiple directions at once. A nor’easter pushing into Manhasset Bay on one side and Little Neck Bay on the other creates a different kind of water intrusion than a single-source storm. Coastal exposure, combined with the age of the housing stock, means restoration here requires more than a shop vac and a few fans — it requires a team that understands what they’re actually dealing with.
Green Island Group is a Long Island company — owned and operated here, not licensed from a corporate brand in another state. When you call, you reach the team that’s actually going to show up at your door. Not a call center. Not a dispatch queue. The same people who answer are the same people managing your job from start to finish.
The Great Neck area is one of the most architecturally diverse communities in Nassau County — nine incorporated villages, homes dating back to the early 1900s in the Old Village, waterfront estates in Kings Point and Great Neck Estates, and a housing stock that demands a crew who knows what they’re working with. We’ve restored homes across the North Shore and understand the specific conditions that come with older construction, coastal exposure, and high-value finishes.
Every job here is also a reference. Great Neck is a tight-knit community, and our reputation travels the same way yours does — through neighbors, through school district networks, through people who actually know each other. We work accordingly.
The first thing that happens when we arrive is a full assessment — not a visual once-over, but a thermal imaging scan and moisture meter reading across every affected area. Water in a Great Neck home doesn’t stay where you can see it. It moves behind plaster, under hardwood subfloor, into finished basement ceilings. We map all of it before we touch anything, so nothing gets missed and everything gets documented.
From there, we set up industrial air movers and desiccant dehumidifiers in the specific areas where moisture readings are elevated. This is different from pointing a fan at a wet floor. These are commercial-grade systems pulling moisture out of the structural materials themselves — the kind of equipment that makes the difference between a dry wall and a wall that tests dry. We monitor readings throughout the drying process and adjust equipment placement as conditions change.
Once the structure is confirmed dry, we walk you through the full scope of what happened, what was affected, and what the documentation looks like for your insurance claim. For Great Neck homeowners carrying both a standard homeowners policy and a separate NFIP flood policy — which is common in the waterfront villages along Little Neck Bay and Manhasset Bay — we understand how to document damage for both and communicate with both adjusters. If any restoration work requires permits through your village’s building department, we handle that coordination as part of the process.

Water damage restoration isn’t one thing — it’s a sequence of things that have to happen in the right order. Emergency water extraction comes first, then structural drying, then moisture verification, then any needed repairs to materials that couldn’t be saved. We handle the full sequence. You’re not coordinating three different contractors or waiting for a second company to come in and finish what the first one started.
New York State’s 2016 Mold Law requires that mold assessment and mold remediation be performed by separately licensed parties, both holding New York State Department of Labor licenses. In Great Neck’s older housing stock, water damage and mold risk are rarely separate conversations — the age of the construction, the coastal humidity, and the way these homes were built means that any significant water event carries a mold exposure risk. We are fully licensed under New York law. That’s not optional in this state, and not every operator working in Nassau County holds the required licenses.
For homes in Kings Point, Saddle Rock, and Great Neck Estates — where properties sit in or near FEMA flood zones — we’re also familiar with the documentation requirements that come with NFIP claims, which differ from standard homeowners insurance claims in ways that matter when you’re trying to get fully reimbursed. High-value home carriers like Chubb and AIG have their own documentation standards as well, and we know how to meet them.
Response time matters more in water damage than almost any other home emergency. Moisture doesn’t wait, and the difference between a crew arriving in 45 minutes versus four hours can be the difference between saving your hardwood floors and replacing them. We dispatch from Long Island and serve the Great Neck area directly — not through a franchise routing system that queues your call behind other regions.
For homeowners in the nine villages of the Great Neck peninsula, from Great Neck Plaza to Kings Point to Saddle Rock, our goal is to have a crew on-site within the hour for active emergencies. We’re available 24 hours a day, seven days a week, and the number you call connects to the team actually serving Nassau County’s North Shore — not an 800 number answered somewhere else. When you’re dealing with a flooded basement at 11 PM on a Sunday, that distinction matters.
It depends on the source of the water, and the answer matters a lot in Great Neck. Standard homeowners insurance typically covers sudden and accidental water damage — a burst pipe, an appliance failure, a roof leak from storm damage. It generally does not cover flooding from an outside water source, which is where NFIP flood insurance comes in.
Many Great Neck homeowners — particularly those in waterfront villages like Kings Point, Great Neck Estates, and Saddle Rock that sit in or near FEMA flood zones — carry both a standard homeowners policy and a separate flood policy through the National Flood Insurance Program. Filing claims under both simultaneously is a process that requires specific documentation for each, and the requirements differ. We work directly with both types of carriers and understand what adjusters need to see to process a claim fully. We handle the documentation and adjuster communication as part of the job, so you’re not navigating two separate claims processes while also managing an active water damage event in your home.
The EPA’s guidance is clear: mold can begin developing within 24 to 48 hours of water intrusion. In Great Neck’s older homes — many built between the 1910s and 1950s with plaster walls, older insulation, and aging subfloor assemblies — moisture doesn’t just sit on the surface. It migrates into structural cavities that look and feel dry within hours of an event. By the time you can see mold, it’s been growing for a while.
Waiting also creates a documentation problem for your insurance claim. Carriers look at the timeline between the event and the remediation call when evaluating claims. A delay can complicate your ability to demonstrate that you took reasonable steps to mitigate damage promptly — which is a standard requirement in most homeowners policies. The safest approach, both for your home and your claim, is to call as soon as you identify the water event, even if you’re not sure yet how serious it is. An assessment costs nothing. Hidden mold in a $1 million home costs a great deal more.
Yes, in specific ways that are worth understanding before you hire anyone. Homes built in the 1920s through 1950s — which make up a significant portion of Great Neck’s housing stock, including many of the Victorian-era homes in the Old Village — were constructed with materials and methods that behave differently under moisture than modern construction. Plaster walls hold moisture differently than drywall. Older wood subfloors absorb water at different rates. Cast iron drain lines and galvanized steel pipes are more prone to failure and can create water events that are harder to trace to a single source.
The restoration process in these homes requires more careful moisture mapping, more precise equipment placement, and a higher level of attention to materials that may be irreplaceable. A custom hardwood floor in a Great Neck home isn’t the same as a builder-grade floor in a newer development — and treating it the same way produces very different results. Our crews are trained to work in high-value, older construction and understand the difference between materials that can be dried in place and materials that need to be carefully removed and documented for replacement.
New York State has specific legal requirements here that apply to every home in Great Neck, regardless of which village it sits in. Under the 2016 New York Mold Law, mold assessment and mold remediation must be performed by separately licensed parties — both holding active New York State Department of Labor licenses. This means the company that assesses for mold cannot legally be the same company that performs the remediation, and both must be licensed by the state.
This matters practically because not every restoration company operating in Nassau County holds the required licenses. If you hire an unlicensed operator — even one who does technically competent work — you may face complications when selling your home, filing an insurance claim, or dealing with a future mold issue that traces back to an unlicensed remediation. In Great Neck’s older housing stock, where water damage and mold risk are closely linked, getting this right the first time is worth the due diligence. Ask any company you’re considering to provide their New York State license number before they start work.
The practical difference comes down to who actually shows up and who’s accountable for the outcome. A national franchise brand like SERVPRO licenses its name to independently owned local operators. The brand on the truck is owned by a corporation, and the local franchise owner purchases the right to use it. The quality of the crew, the response time, and the consistency of the work vary by location and operator — the national brand doesn’t guarantee any of that.
Green Island Group is not a franchise. There’s no licensing arrangement, no corporate brand being rented. We’re a Long Island company, and the people who answer your call are the same people managing your job. For Great Neck homeowners — where the average home value exceeds $1 million and the stakes of a poorly handled restoration are genuinely high — that direct accountability is meaningful. You’re not a ticket in a queue. You’re a homeowner in Kings Point or the Old Village or Great Neck Estates whose home we’re walking into, and we know exactly what that means.
