NYS and NYC M/WBE Certified Contractor
When you’re sitting on a lot worth over a million dollars in Roslyn Heights, a demolition project that stalls — because of a missed permit step, a failed inspection, or an asbestos violation — isn’t just frustrating. It’s expensive. Every delay pushes your rebuild further out, and in a market where land value is this high, that has real financial consequences.
The homes in Roslyn Heights tell the story clearly. With a median construction year of 1955, nearly every full demolition in this community involves materials that require testing before any structural work can legally begin. Asbestos was standard in insulation, floor tiles, roofing shingles, and pipe wrap in virtually every home built during that era. When you work with a contractor who handles both the environmental side and the demolition under one roof, you’re not coordinating between three different companies — you’re making one call and letting the process run.
There’s also the Nassau County Rodent-Free Certificate requirement most homeowners don’t find out about until it slows them down. That certificate expires ten days from the date of inspection, meaning your demolition has to start within that window or you go back to square one. Getting the sequencing right — inspection, permit, utility disconnections, demolition start — is something that takes real experience in this county. That’s exactly what we bring to every Roslyn Heights project.
Green Island Group is a full-service demolition and environmental contractor based on Long Island, serving Nassau County, Suffolk County, and New York City. Over 12 years and more than 340 completed demolition projects across the metro area, our work has ranged from emergency teardowns after storm damage to planned residential demolitions in some of Nassau County’s most established neighborhoods — including Roslyn Heights and the surrounding North Shore communities.
What makes a difference here isn’t just the equipment or the crew size. It’s knowing that the Town of North Hempstead has a historic district designation covering 77 properties near the Roslyn LIRR station — and that if your Roslyn Heights property falls within it, you need Town review before demolition can proceed. It’s knowing PSEG and National Grid both need confirmed disconnections before work starts. It’s knowing the exact sequence that keeps your project on schedule instead of stuck.
We hold EPA, OSHA, and NYS Department of Health asbestos certifications and carry NYS and NYC M/WBE certification. You’re not handing your property over to someone who’s figuring this out as they go.
It starts with a site assessment. Before anything else, the structure gets evaluated — age, size, materials, and condition. For the vast majority of Roslyn Heights homes, which were built before 1980, that assessment includes asbestos testing. If asbestos-containing materials are identified, licensed abatement happens first. That’s not optional under New York State law, and any contractor who skips it is putting you at serious legal and financial risk.
Once abatement is complete, the permit process begins with the Town of North Hempstead’s building department. At the same time, the Nassau County Department of Health Rodent-Free Certificate gets scheduled — and this is where the timing discipline matters. That certificate has a ten-day expiration window, so the inspection, permit approval, and demolition start date all need to be coordinated precisely. Utility disconnections through PSEG and National Grid are confirmed during this same window.
When demolition day arrives, we execute the work cleanly and efficiently. Debris is removed, the site is graded, and the property is left in a condition ready for your next step — whether that’s a new build, a sale, or a clean lot. If your project involves insurance documentation, we handle that alongside the physical work, not after.

House demolition in Roslyn Heights isn’t a single-trade job. The regulatory environment in Nassau County, combined with the age of the housing stock here, means the work consistently involves environmental testing, licensed abatement, coordinated permitting, utility management, and debris disposal — all before the structure itself comes down. We’re built to handle every one of those layers, which is why homeowners throughout Roslyn Heights and the North Shore hire us instead of piecing together separate contractors.
For properties within the Roslyn Heights Historic District — the neighborhood between Willis Avenue and the Roslyn LIRR station — there’s an additional layer of Town of North Hempstead review that applies to any demolition project. This designation was created specifically to prevent demolitions that would alter the character of the community, and the Town takes it seriously. If your address falls within those boundaries, that review process is part of the project plan from day one.
The full scope of what we cover includes asbestos testing and abatement, Nassau County rodent-free certification coordination, Town of North Hempstead permit management, PSEG and National Grid utility disconnection confirmation, full structural demolition, debris hauling and disposal, and site preparation. If the project involves storm or fire damage and you’re navigating an insurance claim, that documentation support is part of the process too — not an add-on you have to ask for separately.
Demolishing a home in Roslyn Heights falls under the Town of North Hempstead’s jurisdiction, since Roslyn Heights is an unincorporated hamlet — meaning permits come from the Town’s building department, not a village office. The permit application requires photographs of all elevations of the structure, a survey with spot elevations at each corner, confirmation of utility disconnections, and a Nassau County Department of Health Rodent-Free Certificate.
That rodent-free certificate is one of the most commonly misunderstood requirements in the Roslyn Heights demolition process. It’s issued by the Nassau County Department of Health after an on-site inspection, and it expires ten days from the date of the inspection. Demolition must begin within that ten-day window — if it doesn’t, the certificate is void and you need a new one. Getting this sequenced correctly with the permit approval and utility disconnections is something that requires real experience in Nassau County, not just general demolition knowledge.
If your home was built before 1980, yes — asbestos testing is legally required before demolition can begin in New York State. In Roslyn Heights, where the median construction year is 1955 and nearly 35% of homes were built before 1950, this applies to the overwhelming majority of properties. Asbestos was used in insulation, floor and ceiling tiles, roofing shingles, pipe wrap, and joint compound in homes built throughout the post-war era.
If testing identifies asbestos-containing materials, licensed abatement must be completed before any structural demolition begins. This isn’t a step that can be skipped or worked around — doing so creates serious legal liability for the homeowner and the contractor. We hold NYS Department of Health asbestos certifications and handle both testing and abatement in-house, so there’s no gap between the environmental work and the demolition work. It’s one continuous, coordinated process.
The honest answer is that it depends on the scope, but for a full residential demolition in Nassau County, you should budget realistically in the range of $12,000 to $35,000 or more. That range accounts for the size of the structure, whether foundation removal is included (which typically adds $2,000 to $10,000 on its own), debris disposal, permit fees, and — critically — asbestos abatement if required.
The New York metro area runs 20 to 30 percent higher than national averages for demolition, and Nassau County’s regulatory requirements add real cost to any project. Asbestos abatement, rodent-free certification, and Town of North Hempstead permit fees are all line items that need to be in the budget from the start. What you want to avoid is a low quote that doesn’t account for those requirements — because they don’t disappear just because a contractor didn’t mention them. A complete, itemized scope of work upfront is the only way to know what you’re actually committing to.
Demolition within the Roslyn Heights Historic District requires review and approval from the Town of North Hempstead before work can proceed. The historic district — which covers 77 properties in the neighborhood between Willis Avenue and the Roslyn LIRR station — was established in 1999 specifically in response to a demolition proposal that would have altered the character of the community. The Town takes preservation seriously within these boundaries, and the review process is more involved than a standard demolition permit.
That doesn’t mean demolition is impossible within the district. It means the process requires additional steps and documentation, and it needs to be planned for from the beginning — not discovered midway through the permit application. If you’re not sure whether your property falls within the historic district boundaries, that’s one of the first things worth confirming before you move forward with any plans. We identify this upfront during the initial assessment so there are no surprises down the line.
The physical demolition of a single-family home typically takes one to three days depending on size and complexity. But the full timeline — from initial assessment to cleared site — is usually four to eight weeks when you account for asbestos testing results, abatement if needed, the Nassau County rodent-free certificate inspection, and Town of North Hempstead permit approval.
Utility disconnections through PSEG and National Grid also need to be scheduled and confirmed before work can begin, and those coordination timelines can vary. The biggest source of delays in Nassau County demolition projects isn’t the demolition itself — it’s the pre-demolition sequencing. When the permit application, rodent certificate inspection, utility disconnections, and demolition start date aren’t coordinated precisely, the ten-day certificate window expires and the process resets. Working with a contractor who has managed this sequence repeatedly in Nassau County is the most reliable way to keep your timeline intact.
After the structure comes down, all debris is removed from the property and disposed of properly — including materials that require specific handling, like concrete, metal, and any remaining hazardous materials that were identified during the abatement phase. The site is then graded to leave it in a clean, level condition ready for whatever comes next.
For most Roslyn Heights homeowners, “what comes next” is a new custom build. With land values exceeding a million dollars in this community, the teardown-and-rebuild cycle is well established on the North Shore — and a properly cleared, graded lot is the starting point for that process. If you’re working with a builder or architect already, the site preparation can be coordinated to meet their specific requirements. And if your demolition is connected to a storm, fire, or flood insurance claim, the documentation needed for that claim — scope of work, material records, debris removal confirmation — is part of what we handle alongside the physical work, not something you’re left to pull together on your own afterward.
