NYS and NYC M/WBE Certified Contractor
Old Brookville’s estate properties sit on wooded lots that most of Nassau County simply doesn’t have. The mature oaks and hardwoods that line Chicken Valley Road and wind through the village’s multi-acre properties are stunning — until a nor’easter loads them with ice or a tropical system pushes 60 mph gusts across the North Shore. When one of those trees comes down on a roof, what you see from the driveway is rarely the whole story. Water moves fast through a large home. It gets behind finished walls, into attic insulation, under flooring. Mold begins growing within 24 to 48 hours of intrusion — and in a 5,000-square-foot estate, that window matters more than most people realize until they’re looking at a five-figure remediation bill that same-day response would have prevented.
The other piece that’s specific to Old Brookville is the age of the housing stock. The median construction year in the village is 1965, and roughly a quarter of homes here predate 1950. That means asbestos-containing insulation, lead paint, and older building materials are a realistic part of the picture when storm damage opens up walls or disturbs roofing. A contractor without the right specialty licenses has to stop work and call someone else — which means delays, liability gaps, and a restoration that stalls while your home is still exposed. We hold every license required to handle the full scope without interruption: mold remediation, asbestos abatement, lead certification, and Nassau County general contracting. One call covers all of it.
Green Island Group is a full-service disaster restoration and remediation company serving Nassau County, Suffolk County, Queens, and New York City — operating around the clock, every day of the year. We hold a Nassau County General Contractor license, NYS DOL Mold Remediation and Asbestos Handler licenses, USEPA Lead and RRP certifications, and the NYS Office of General Services Approved Emergency Response Contractor designation — a government-level credential that most restoration companies, including national franchise brands, simply cannot claim.
For homeowners in Old Brookville, that credential stack isn’t a formality. It’s the difference between a restoration that gets done correctly — legally, safely, and completely — and one that stalls the moment a complication surfaces. When storm damage opens up a pre-1978 home on a multi-acre lot off Route 107, the job is rarely straightforward. We’re built for exactly that kind of project. Our team bills insurance carriers directly, handles all permitting through the Town of Oyster Bay, and backs every job with full liability coverage, workers’ compensation, and a 100% satisfaction guarantee.
When you call, someone answers — regardless of the hour. The first priority is stopping the damage from getting worse. That means emergency board-up, roof tarping, debris removal, and structural securing as needed. For a large estate property in Old Brookville, this phase can involve significant tree and debris clearing before any interior assessment even begins. The goal is to get your home protected and stable before the next weather event compounds what’s already happened.
Once the property is secured, the assessment begins in full. We use industrial thermal imaging cameras and commercial moisture meters to map every affected area — not just what’s visible, but what’s hidden inside walls, beneath flooring, and behind finished ceilings. This documentation matters for two reasons: it drives the remediation scope, and it drives your insurance claim. Incomplete documentation is one of the most common reasons homeowners get underpaid on storm damage claims. We capture everything before a single repair is made.
From there, the work moves in sequence — water extraction, structural drying, mold assessment, and any specialty remediation required under New York State law. Because Old Brookville’s housing stock includes a significant number of pre-1978 homes, asbestos and lead surveys are part of the standard process when the damage scope warrants it. Building permits are pulled through the Town of Oyster Bay’s Department of Planning and Development, and any work touching the exterior of a village property is handled with the Architectural Review Board requirements in mind. Reconstruction begins once all remediation is complete and the structure is cleared.

Storm damage restoration in Old Brookville isn’t a single-trade job. A fallen tree that penetrates a roofline on a 4-acre estate triggers a chain of work that touches structural repair, water damage mitigation, mold remediation, and potentially asbestos or lead abatement — all before reconstruction can begin. We handle every phase of that chain in-house. There’s no handoff to a subcontractor when a specialty license is required, no gap in accountability between the remediation crew and the rebuild team, and no delay while a second company gets scheduled.
The scope of what we cover includes emergency board-up and tarping, tree and debris removal, full water extraction and structural drying, thermal imaging assessment, mold testing and remediation, asbestos and lead surveys and abatement where applicable, and complete structural reconstruction. We also manage the insurance claim process directly — communicating with your carrier, documenting damage to support your claim, and billing the insurance company so you’re not carrying the cost out of pocket while the work is underway.
For Old Brookville homeowners, the permit process is part of the service too. Structural repairs in the Town of Oyster Bay require building permits through the Department of Planning and Development, and the village’s own Architectural Review Board may be involved depending on the scope of exterior work. We navigate all of it — so your restoration moves forward without you managing the bureaucracy while your home is still exposed to the elements.
In most cases, yes — but the details matter. Standard homeowners insurance policies in New York typically cover sudden and accidental storm damage, which includes wind damage, falling trees, and water intrusion caused by a storm event. What they often don’t cover is damage that results from deferred maintenance or pre-existing conditions, which is why thorough documentation at the time of loss is critical. If your roof had a known issue before the storm, your carrier may try to attribute part of the damage to that — and without proper documentation, it’s hard to push back.
We handle the insurance process directly. Our team documents all damage using thermal imaging and moisture mapping before any repairs begin, communicates with your adjuster, and bills your carrier directly. For homeowners in Old Brookville — where a single storm damage claim on an estate property can run well into six figures — having someone in your corner who knows how to document and present a claim correctly is not a small thing. It can be the difference between a full payout and a significant shortfall.
Mold begins growing within 24 to 48 hours of water intrusion — and that timeline doesn’t slow down because the storm just ended or because it’s the middle of the night. In a large home, water migrates quickly through wall cavities, insulation, and subfloor materials in ways that aren’t visible from the surface. By the time you see discoloration or smell something off, the growth is often already established behind the finish.
This is why same-day response matters so much in Old Brookville specifically. Estate properties here are large, and the square footage of finished living space means there’s a lot of area for water to move through undetected. A prompt assessment with thermal imaging — not just a visual walkthrough — is what catches intrusion before it becomes a mold problem. The cost difference between catching it in the first 24 hours and addressing it after it’s established behind walls is substantial. We operate around the clock precisely because that window is real.
The first thing is to get everyone out of the affected area of the home — structural integrity after a major tree impact is not something to assume. Once you’re clear, call a licensed restoration contractor before you call anyone else, including a tree service. A tree service will cut the tree off your roof, but they won’t assess the structural damage beneath it, extract the water that’s already entered, or secure the opening against the next rain event. If you remove the tree without first securing the penetration, you’re compounding the damage.
Our emergency response team handles the full sequence: debris removal, emergency structural securing, roof tarping, and immediate water extraction — all in one mobilization. In Old Brookville, where mature hardwoods on large wooded lots can weigh tens of thousands of pounds, a tree-fall is a structural event, not a roofing repair. The scope of the assessment that follows needs to match the scale of what just happened. Call 24/7 and we’ll walk you through what to do while we’re on the way.
For most structural repairs — roof replacement, wall reconstruction, anything that affects the building envelope — yes, a permit is required through the Town of Oyster Bay’s Department of Planning and Development. Emergency work like tarping, board-up, and temporary securing can typically proceed without a permit, but any permanent repair work needs to go through the proper permitting process. Skipping this step creates real problems: unpermitted work can affect your insurance claim, complicate a future sale, and create liability if something goes wrong.
Old Brookville adds another layer. The village maintains its own Zoning Code and has an active Architectural Review Board that may need to be involved if exterior restoration work is significant enough to affect the character of the structure. This isn’t bureaucracy for its own sake — the village’s strict standards around architectural consistency are part of what protects property values here. We handle permit applications and compliance as part of the restoration scope. You don’t need to manage the Town of Oyster Bay’s process yourself while your home is still exposed.
If your home was built before 1978, lead paint is a realistic possibility. If it was built before 1980, asbestos-containing materials — in insulation, floor tiles, roofing, or pipe wrapping — are common enough that they should be assumed until a licensed inspector confirms otherwise. In Old Brookville, where the median construction year is 1965 and roughly a quarter of homes predate 1950, this isn’t a rare edge case. It’s a standard consideration on a meaningful percentage of storm damage jobs in the village.
When storm damage opens up walls, disturbs roofing materials, or exposes insulation, those materials may become a hazard that requires licensed abatement before restoration can proceed. A contractor without NYS DOL Asbestos Handler and USEPA Lead certifications cannot legally perform that work in New York — which means they stop, you wait, and your home stays exposed while a second company gets scheduled. We hold both certifications and perform all specialty remediation in-house. The survey happens as part of the initial assessment, so if abatement is needed, it’s built into the restoration sequence without delay.
After any significant nor’easter or tropical event on Long Island, unlicensed contractors show up — sometimes door to door, sometimes through social media, sometimes with lowball estimates that disappear once a deposit is collected. The pressure of a damaged home makes it tempting to move fast, but moving fast with the wrong contractor creates a second problem on top of the first. Unpermitted work, improper remediation, and incomplete repairs all cost more to undo than the original damage.
The simplest way to verify a contractor in New York is to check their licenses directly. A Nassau County General Contractor license is publicly verifiable. NYS DOL Mold Remediation and Asbestos Handler licenses are searchable through the state’s licensing database. The NYS Office of General Services Approved Emergency Response Contractor designation requires state-level vetting that storm chasers simply don’t have. We hold all of these — and carry full liability insurance and workers’ compensation coverage on every job. For a property worth what homes in Old Brookville are worth, that verification step takes five minutes and protects everything.
