NYS and NYC M/WBE Certified Contractor
The split-levels and raised ranches that line Grand Boulevard and Brush Hollow Road in New Cassel weren’t built with modern storm resistance in mind. When wind tears through aging shingles or a mature tree comes down on your roof, water doesn’t wait. It moves fast through uninsulated wall cavities, under subflooring, and into lower levels — often without a single visible sign on the surface until the damage is already deep.
That’s the part most contractors miss. A crew that shows up, patches the roof, and leaves hasn’t solved your problem. They’ve covered it. What you actually need is someone who can find every pocket of moisture before it turns into mold, and who holds the specific licenses to handle what’s inside a home built before 1980 — because asbestos-containing insulation and lead-based paint are common in New Cassel’s housing stock, and disturbing them without the right credentials isn’t just risky, it’s illegal.
When the job is done right, you’re not just back to where you were before the storm. Your home is documented, dried, repaired, and cleared — and your insurance claim has been handled from start to finish without you fronting a dollar. That’s what a complete restoration actually looks like.
Green Island Group is an NYS Office of General Services Approved Emergency Response Contractor — a government-level credential that requires state vetting before any job is booked. That’s not a marketing badge. It means the state has already reviewed our qualifications, and you’re not taking a chance on an unknown crew showing up after a storm in New Cassel.
We hold a Nassau County General Contractor license alongside NYS DOL Mold Remediation, NYS DOL Asbestos Handler, USEPA Lead, and USEPA RRP certifications. In a hamlet governed directly by the Town of North Hempstead — where building code enforcement has been actively heightened as part of New Cassel’s long-running revitalization effort — those credentials aren’t optional. They’re what separates a legal, complete restoration from one that creates new problems down the road.
We’re not a national franchise. We’re a Long Island company that knows New Cassel’s housing stock, knows the Town of North Hempstead’s permitting process, and answers the phone at 2 AM when the storm doesn’t wait.
When you call, we respond — 24 hours a day, every day of the year. The first priority is stopping the damage from spreading. That means emergency tarping, board-up, and securing the property so that what started as a roof breach doesn’t become a fully saturated interior by morning.
Once the property is stabilized, we do a full thermal imaging inspection. This matters in New Cassel specifically because the split-level and Cape Cod floor plans common here have multiple interior levels and wall cavities that hide moisture completely. We’re not guessing where the water went — we’re documenting it with industrial equipment before it becomes a mold problem. From there, we move into water extraction, structural drying, and material assessment. If asbestos or lead is in the damage path — and in a pre-1980 home, it often is — we handle that in-house under our NYS DOL and USEPA certifications. No subcontractors, no handoffs, no gaps in accountability.
Before any structural repair begins, we pull the required permits through the Town of North Hempstead. We also coordinate directly with your insurance adjuster, document everything the claim requires, and bill the carrier. You’re kept in the loop at every step, but you’re not managing the paperwork. We are.

Storm damage in New Cassel rarely stops at the roof. A single weather event — a Nor’easter, a severe thunderstorm, a downed tree on a small lot where homes sit close together — can trigger a chain of damage that runs from the shingles down through the framing, insulation, and interior finishes. We handle every link in that chain.
The scope of what we cover includes emergency tarping and property securing, debris and tree removal, industrial water extraction, structural drying and moisture mapping, mold prevention and remediation, asbestos and lead abatement where required, roof repair and replacement, siding restoration, and full interior rebuild. Every phase is handled by our own licensed team — not passed off to a subcontractor you’ve never met.
For New Cassel homeowners navigating the insurance process — especially those doing it for the first time — we handle all documentation, adjuster coordination, and direct insurance billing. No upfront costs while your home is being restored. We also manage the Town of North Hempstead permit process from start to finish, so you’re not left holding an unpermitted repair in a hamlet where code enforcement is active and ongoing. When we leave, the job is done, documented, and legally complete.
In most cases, yes — but the details matter. Standard homeowners insurance policies typically cover sudden and accidental storm damage, including wind damage, roof breaches, fallen trees, and water intrusion that results directly from the storm event. What they often don’t cover is damage that’s attributed to deferred maintenance or pre-existing conditions, which is why thorough documentation from the moment we arrive is critical.
In New Cassel, where a significant portion of the housing stock is midcentury construction, adjusters will sometimes attempt to attribute damage to the age or condition of the roof rather than the storm itself. That’s exactly why having a licensed contractor who documents the damage with thermal imaging and a detailed written assessment — before anything is touched — gives your claim the strongest possible foundation. We handle the entire process: documentation, adjuster coordination, and direct billing to your carrier. You don’t pay out of pocket while the work is being done.
Mold can begin developing within 24 to 48 hours of water intrusion — and in the older homes that make up most of New Cassel’s residential blocks, that timeline can move even faster. The Cape Cod and split-level construction common here often has limited insulation and aging building materials that absorb moisture quickly, giving mold the warm, damp environment it needs to take hold before you’d ever notice a smell or visible growth.
This is why speed of response isn’t just a convenience — it’s a financial decision. A roof breach that gets addressed within hours typically stays a roof repair. The same breach left unaddressed overnight can turn into a mold remediation that costs several times more and takes significantly longer to resolve. If a storm hits your New Cassel home, calling sooner rather than waiting to see how bad it gets is almost always the right call. We’re available around the clock specifically because the damage window doesn’t follow business hours.
Yes — any structural repair in New Cassel requires a permit from the Town of North Hempstead, which governs all building and code enforcement for the hamlet directly. Because New Cassel is an unincorporated area with no village government, there’s no separate village building department. Everything runs through North Hempstead, and the town has been actively enforcing building codes here as part of its long-running community revitalization effort along the Prospect Avenue corridor and surrounding residential blocks.
Unpermitted storm repairs in this environment carry real risk — not just a theoretical one. A repair done without proper permits can affect your property’s title, create complications when you sell, and expose you to enforcement action. We handle the entire permit process with the Town of North Hempstead as part of every job. You don’t need to track down forms, make calls to the building department, or manage inspections. We take care of it from application to final sign-off.
It does, and it’s one of the most important things to understand before hiring any contractor for storm work in this area. Homes built before 1980 — which describes the vast majority of New Cassel’s housing stock — commonly contain asbestos in insulation, floor tiles, pipe wrap, and roofing underlayment, as well as lead-based paint on interior and exterior surfaces. When a storm breaches a roof or drives water through a wall, those materials are often disturbed in the process.
In New York State, disturbing asbestos or lead in a residential structure requires specific licensure from the NYS Department of Labor and the USEPA. Most general contractors — including most storm contractors operating in Nassau County — do not hold these credentials. We hold both NYS DOL Asbestos Handler certification and USEPA Lead and RRP certifications, which means we can legally and safely handle the full scope of damage in a pre-1980 home without stopping the job to bring in a separate abatement contractor. It’s a meaningful difference, and in New Cassel’s housing stock, it comes up regularly.
The honest answer is that it depends on the scope, but most residential storm damage restorations in Nassau County fall somewhere between a few days for straightforward roof and water damage to several weeks for jobs involving significant structural work, mold remediation, or hazardous material abatement. The timeline is also affected by permit processing through the Town of North Hempstead, which we factor into every job schedule from the start.
What affects your specific timeline most is how quickly work begins after the storm. The longer water sits in a structure — especially in New Cassel’s older homes where materials absorb moisture readily — the more material needs to be removed and replaced rather than simply dried. Emergency response on day one can meaningfully shorten the overall restoration timeline by preventing secondary damage from compounding. We give you a realistic scope and timeline after the initial inspection, and we keep you updated throughout. No surprises, no scope creep without your knowledge.
The most important thing is to stay out of any area of the home where structural integrity is uncertain. If a tree has come through the roof, the surrounding framing may be compromised in ways that aren’t immediately visible. Don’t try to remove debris yourself, and don’t go into an attic or upper-level space to assess the damage — that’s our job, and we have the equipment to do it safely.
If it’s safe to do so from a distance, document what you can see with photos before anything is moved. This supports your insurance claim. Then call your insurance company to open a claim and call us — we’ll respond, secure the property with emergency tarping to stop weather from continuing to enter, and begin the formal damage assessment. In New Cassel’s densely packed residential blocks, where lots are small and homes sit close together, a downed tree can affect more than one property. If a neighbor’s tree came down on your home, that’s a common scenario we’ve handled, and the insurance coordination process is something we can walk you through from the first call.
