NYS and NYC M/WBE Certified Contractor
When a demolition project goes wrong in Great Neck, it usually isn’t because of the wrecking crew — it’s because someone didn’t know what came before it. Asbestos testing that wasn’t done. A rodent inspection certificate that expired before the permit was filed. A village building department that nobody called. These aren’t rare edge cases here. They’re the norm.
Great Neck’s housing stock tells the story. More than 27% of homes on the peninsula were built before 1939, and the overwhelming majority predate 1980. That means asbestos in the pipe insulation, the floor tiles, the boiler block. It means lead paint on nearly every surface. It means a home that legally cannot be touched by a demolition crew until a certified abatement contractor has cleared it — and in New York State, that’s not optional.
When you work with a contractor who handles testing, abatement, permits, and demolition under one roof, you’re not just buying convenience. You’re buying a project that doesn’t stall at the permit office, doesn’t get hit with a stop-work order, and doesn’t put your builder’s start date at risk. For a teardown-and-rebuild on a lot worth close to a million dollars in a school district this competitive, that’s not a small thing.
Green Island Group has been doing demolition work across Nassau County and the New York metro area for over 12 years. More than 340 completed projects. EPA certified. NYS DOH licensed for asbestos abatement. NYC DOB licensed. OSHA certified. NYS and NYC M/WBE certified — a government-issued credential, not a self-reported one.
We’ve worked throughout North Hempstead, including properties across the Great Neck peninsula — from older colonials near Great Neck Plaza to estate-era homes in Great Neck Estates and Saddle Rock Estates. We know the Town of North Hempstead’s permit requirements, the Nassau County Department of Health’s rodent inspection process, and the village-level building department nuances that vary from one end of the peninsula to the other. We’ve managed demolitions on properties backing onto Little Neck Bay and Manhasset Bay, where coastal proximity affects drainage and site preparation requirements.
What you’ll notice, beyond the credentials, is that real people answer the phone here. Named staff. Documented response times. A 4.7-star rating built on specific projects, not generic praise. That’s the kind of accountability that matters when your project is on the line.
It starts with a site assessment. We look at the structure, the age of the building, and what’s likely inside it. For any home built before 1980 — which covers most of Great Neck’s housing stock — we conduct certified asbestos testing before anything else happens. If materials come back positive, abatement happens first, handled by our in-house licensed team. No waiting on a separate subcontractor to finish before we can start.
Once the site is cleared, we handle the permit process. In Great Neck, that means coordinating with your specific village’s building department — whether that’s Kensington, Great Neck Estates, Great Neck Plaza, or another of the nine incorporated villages on the peninsula — alongside the Town of North Hempstead’s requirements. One of those requirements is the Nassau County Department of Health Certificate of Rodent Free Inspection, which expires just 10 days from issuance and must be submitted simultaneously with the permit application. It’s a tight window. We manage it.
After permits are approved and utilities are disconnected, demolition begins. We use proper containment, HEPA-filtered equipment, and certified disposal for all hazardous materials. When the structure is down, the site is cleaned, graded, and ready for your builder. The whole process — from first call to clean lot — runs on a timeline your builder can actually plan around.

House demolition in Great Neck isn’t a single transaction — it’s a sequence of regulated steps, and every one of them has to be done in the right order by the right people. Here’s what’s included when you work with Green Island Group.
Asbestos and hazardous material testing comes first. Given that the vast majority of homes on the Great Neck peninsula predate 1980, this step is essentially standard. We test, document, and if abatement is required, we handle it in-house with our NYS DOH-licensed team. No handoffs, no gaps in accountability. From there, we manage the full permit process — village-level building permits, Town of North Hempstead demolition permits, Nassau County health documentation, and NYS Department of Labor oversight where applicable. The Village of Kensington, the Village of Great Neck Estates, and Great Neck Plaza each have their own requirements. We know them.
Structural demolition is performed with equipment and methods appropriate for Great Neck’s dense, residential peninsula environment — where your neighbors are close, the building departments are watching, and sloppy work has consequences. Debris is removed and disposed of according to Nassau County and state regulations. The finished site is graded and left clean. And if your project involves insurance — fire damage, storm damage from a nor’easter off the Long Island Sound, flooding from Manhasset Bay — we work directly alongside your adjuster from the start.
Yes — and in Great Neck, the permit process is more layered than most people expect. Because the Great Neck peninsula is made up of nine incorporated villages, the permit you need depends on which village your property sits in. The Village of Kensington, the Village of Great Neck Estates, and the Village of Great Neck Plaza each have their own building departments and their own demolition permit requirements. On top of that, properties in unincorporated areas fall under the Town of North Hempstead’s Department of Building, Safety Inspection and Enforcement.
Beyond the village or town permit, the Town of North Hempstead also requires a Nassau County Department of Health Certificate of Rodent Free Inspection as part of the demolition permit application. That certificate expires 10 days from the date it’s issued, and it must be submitted at the same time as the permit application — not before, not after. Missing that window means starting the inspection process over and losing time. We manage all of it for you, so your project doesn’t stall over paperwork.
Almost certainly yes. New York State law requires certified asbestos testing and abatement before any demolition can legally proceed on a building that may contain asbestos-containing materials. In Great Neck, that applies to the vast majority of the housing stock — more than 27% of homes on the peninsula were built before 1939, and most of the rest predate 1980, which is when asbestos use in construction materials was phased out.
In these homes, asbestos is commonly found in pipe insulation, boiler block insulation, 9×9 vinyl floor tiles and their black mastic adhesive, ceiling tiles, roofing shingles, and certain siding materials. You won’t always know it’s there by looking at it — that’s what testing is for. If materials test positive, a NYS DOH-licensed abatement contractor must remove and dispose of them before any structural demolition begins. We handle both the testing and the abatement in-house, which means no waiting on a separate company to finish before we can move forward.
Demolition costs in the New York metro area run higher than national averages — typically 20 to 30% above what you’d see quoted in other parts of the country. In Nassau County, and particularly in a high-regulation market like Great Neck, a full house demolition on a 2,000 square foot home typically runs from $18,000 to $40,000 or more depending on the size of the structure, the extent of hazardous materials present, and the complexity of the permit process.
Several factors push costs up in Great Neck specifically: the age of the housing stock (older homes mean more asbestos and lead paint remediation), the dense residential environment (which requires more careful equipment use and containment), and the multi-layer permit process across village and town jurisdictions. That said, for a teardown-and-rebuild on a lot worth close to $1 million in one of Nassau County’s top school districts, the demolition cost is typically a small line item in the overall project budget. What costs far more is a project that stalls because of a permit violation or an abatement issue that wasn’t caught up front.
The physical demolition of a house — once everything is in place — usually takes one to three days for a standard residential structure. But in Great Neck, the full timeline from first call to clean lot is longer than that, and it’s largely driven by the pre-demolition steps that have to happen first.
Asbestos testing takes a few days to process. If abatement is required, that adds one to two weeks depending on the scope. Permit approval timelines vary by village — the Village of Great Neck Estates issues permits that expire 45 days after issuance, which gives you a sense of the pace. The Nassau County rodent inspection has to be scheduled, completed, and the certificate submitted within a 10-day window. Utility disconnection — gas, electric, water, sewer — has to be confirmed before work begins. Realistically, from first call to demolition start, you should plan for four to eight weeks in this market. If you’re working toward a specific builder start date, the earlier you initiate the process, the better. Families aiming to be in a new home before the Great Neck school year begins in September should be starting the demolition process no later than early spring.
Yes, and this is a situation we handle regularly. Great Neck’s location on a peninsula between Little Neck Bay, Manhasset Bay, and the Long Island Sound means coastal storm exposure is a real and recurring factor. Nor’easters, tropical storm remnants, and coastal flooding have compromised structures on the peninsula before, and they will again. When a home sustains significant structural damage from a storm event, the decision to demolish rather than repair is often urgent — and the process has to move quickly.
We are available 24 hours a day, 7 days a week, 365 days a year for emergency response. We have documented cases of arriving on-site within one hour during active weather events. Beyond the physical work, we also work directly alongside homeowners through the insurance claim process — helping document damage, coordinating with adjusters, and making sure the scope of work is accurately captured from the start. If your home has been declared a total loss or the repair cost exceeds the rebuild cost, we can help you navigate both the demolition and the insurance side of it at the same time.
For many homeowners on the Great Neck peninsula, the math on teardown versus renovation has shifted significantly in recent years. Land values here are high enough — median lot values approaching and often exceeding $1 million — that demolishing an aging 1940s or 1950s structure and replacing it with new construction often makes more financial sense than trying to bring an older home up to modern standards. You’re not buying a 1950s Cape Cod in Great Neck. You’re buying the lot, the school district, the LIRR access, and the peninsula address. The existing structure is frequently the obstacle.
The teardown-and-rebuild cycle is active across the peninsula right now. Saddle Rock Estates is seeing new luxury colonials exceeding 5,000 square feet going up on teardown lots. Buyers who move into the Great Neck Union Free School District — consistently ranked among the top districts in New York State — are making long-term investments, and a new build reflects that. The renovation calculus changes when you factor in the cost of bringing pre-war mechanical systems, electrical, plumbing, and structural elements up to current code, plus the mandatory asbestos and lead paint remediation that older homes require before any significant work can begin. In many cases, a clean teardown and new build is the more straightforward path — financially and logistically.
