NYS and NYC M/WBE Certified Contractor
When you’re dealing with an older home in Oyster Bay — whether it’s a pre-war colonial off East Main Street or a mid-century Cape Cod closer to the harbor — the reality is that almost every demolition project has something hiding inside the walls. Asbestos in the floor tiles. Lead paint layered under decades of renovation work. Sometimes both. A contractor who can’t legally handle those materials isn’t a complete solution. They’re half a job.
What you actually get with a licensed demolition contractor is the full picture handled start to finish. No stopping mid-project because a hazmat issue came up. No scrambling to find a second company to come in and deal with what the first one couldn’t touch. The scope gets assessed honestly upfront, the right permits get pulled, and the work gets done in the right order — abatement first, demolition after, documentation at the end.
That documentation matters more in Oyster Bay than people realize. With median home values above $634,000 and properties that regularly change hands in the North Shore market, the paper trail from your demolition project — disposal manifests, clearance certificates, permit records — becomes part of your property’s history. Buyers ask about it. Attorneys look for it. Having it protects you.
Green Island Group is a Long Island-based environmental contracting and demolition firm. The reason clients in Oyster Bay keep coming back — and keep referring neighbors — is straightforward: we hold the asbestos handling license, the lead certifications, and the demolition credentials under one roof. You don’t have to coordinate two or three separate contractors to get a single project done legally.
That matters specifically in Oyster Bay, where the building stock spans from colonial-era structures near Raynham Hall to post-WWII ranches throughout the hamlet. The Town of Oyster Bay also has a 50-year historic review rule that applies to demolition permits on older structures — a local requirement that catches a lot of out-of-area contractors off guard. We know that process. We’ve worked with the Building Division at 74 Audrey Ave, and we know what the Town’s Planning Department expects before a permit moves forward.
Our reviews reflect what clients actually care about: someone picked up the phone, showed up when they said they would, and made a stressful situation feel manageable. That’s the standard we hold ourselves to on every job in Oyster Bay.
It starts with an assessment. Before anything gets touched, we walk the property and look at what’s actually there — the age of the structure, the materials involved, and whether there are any regulated substances that need to be addressed before demolition begins. In Oyster Bay, where most of the housing stock predates 1980, this step almost always turns up something. We tell you what we find, clearly and without drama, so you can make an informed decision.
From there, we handle permitting. The Town of Oyster Bay requires a demolition permit for any structure beyond a small storage shed, and if the building is more than 50 years old — which applies to the majority of homes in the hamlet — there’s an additional public site plan review process. We manage that on your behalf. If asbestos or lead is present above regulated thresholds, we also file the required EPA NESHAP notification at least 10 working days before work begins.
Once permits are in place, abatement happens first. Hazardous materials are contained, removed, and disposed of by our licensed crew with full chain-of-custody documentation. Demolition follows. After the work is complete, we conduct post-project air clearance testing to confirm the space is clean, and we hand you the full documentation package — everything you need for your records, your next contractor, or your future closing table.

We handle residential and commercial demolition across the full range of project types you’ll find in Oyster Bay and the surrounding North Shore communities. Interior selective demolition for gut renovations — kitchens, bathrooms, basements, full floor gut-outs. Structural demolition for properties that need to come down entirely. Post-storm or water damage demolition for harbor-adjacent properties where flood zone rules add a layer of regulatory complexity that most contractors aren’t prepared for.
For properties near Oyster Bay Harbor, the FEMA Substantial Damage rule is a real consideration. If storm or water damage to a flood-zone property exceeds 50% of its pre-damage market value, the Town requires full FEMA-compliant reconstruction rather than repair. That changes the scope of the project significantly, and it’s something we identify early — not after work has already started. The surrounding villages of Oyster Bay Cove, Cove Neck, Laurel Hollow, and Bayville fall within our service area as well, and the same integrated approach applies regardless of which side of the hamlet line your property sits on.
On the commercial side, the active revitalization happening along Oyster Bay’s Main Street corridor — with over $700,000 in secured grants for building improvements — means older commercial structures are being assessed and renovated. Those buildings carry the same hazardous materials risks as the residential stock, and they require a contractor with both commercial demolition capability and the asbestos licensing to handle what’s inside. We do both.
Yes — the Town of Oyster Bay requires a demolition permit for any building or structure beyond a portable tool shed or noncommercial storage building 100 square feet or less. That includes interior structural work like removing load-bearing walls, not just full building demolition. Applications are processed through the Building Division at 74 Audrey Ave in Oyster Bay.
There’s an additional layer worth knowing about. If the structure is more than 50 years old at the time of your permit application — which applies to the majority of homes in Oyster Bay — the Town requires a public site plan review before the permit is issued. This review assesses the historic and architectural character of the site and the surrounding neighborhood. It’s not a formality, and it can affect your project timeline if you’re not prepared for it. We handle the permitting process on behalf of our clients and know what the Town expects at each stage.
The honest answer is: you don’t know until it’s tested. Visual identification isn’t reliable — asbestos-containing materials often look identical to non-hazardous ones. What you can go by is age. Homes built before 1980 are considered high-risk for asbestos in floor tiles, ceiling texture, pipe insulation, joint compound, roofing materials, and HVAC components. In Oyster Bay, where the housing stock spans from colonial-era structures through post-WWII construction, the majority of residential properties fall into that category.
The right move before any demolition or major renovation is a professional asbestos inspection by a licensed inspector. If regulated materials are present above threshold quantities, they have to be removed by a NYS Department of Labor licensed asbestos handling contractor before demolition can proceed — and the EPA requires notification at least 10 working days in advance. Skipping this step doesn’t make the liability disappear. It transfers it to you as the property owner. We assess for hazardous materials as part of our standard pre-demolition process so there are no surprises mid-project.
It depends on where the property sits and how extensive the damage is. For properties in FEMA-designated flood zones along Oyster Bay Harbor, the Substantial Damage rule applies. If the cost to restore the property to its pre-damage condition exceeds 50% of the structure’s pre-damage market value, the Town of Oyster Bay Building Department requires full FEMA-compliant reconstruction — not just repair or partial demo. That’s a meaningful distinction that affects the entire scope and cost of the project.
Before any demolition work begins on a storm-damaged property, it’s worth having the damage assessed against that 50% threshold. If you’re over it, the reconstruction requirements kick in and need to be factored into your planning. If you’re under it, you have more flexibility. Either way, the hazardous materials question still applies — a storm-damaged home that’s been flooded or structurally compromised may have disturbed existing ACMs, which means abatement needs to happen before or alongside demolition. We assess both issues upfront so you know exactly what you’re dealing with before work starts.
Timeline depends on the scope, but there are a few Oyster Bay-specific factors that affect scheduling. The permit process at the Town of Oyster Bay Building Division takes time — and if your structure triggers the 50-year historic review requirement, that public process adds additional lead time before a permit is issued. For projects with asbestos above regulated thresholds, EPA NESHAP notification must be filed at least 10 working days before work begins, which is a fixed waiting period regardless of how quickly everything else moves.
For a straightforward interior selective demolition — a kitchen gut, bathroom removal, or basement clear-out — the physical work itself often takes one to three days once permits and any required abatement are handled. Full structural demolition of a residential building typically runs one to three days on-site as well, though the pre-work phase of permitting and abatement can extend the overall timeline by several weeks. We give you a realistic project schedule during the assessment phase so you’re not caught off guard, and we manage the permit and notification timelines on your behalf.
Yes — that’s one of the core reasons clients in Oyster Bay choose us over a general demolition contractor. We hold a NYS Department of Labor Asbestos Handling Contractor License, which is the legal authorization required to disturb, remove, and dispose of asbestos-containing materials in New York State. A general demolition contractor without that license cannot legally perform abatement work. When those contractors encounter asbestos mid-project, the job stops until a licensed abatement company is brought in — which means scheduling delays, additional coordination, and a gap in accountability between two separate companies.
When you hire Green Island Group, the same licensed team that assesses for hazardous materials is the team that removes them and executes the demolition. There’s no handoff, no scheduling gap, and no situation where one contractor is blaming another for a problem. The full scope — assessment, abatement, demolition, documentation — runs through one company. For Oyster Bay homeowners dealing with properties where hazardous materials are almost a given, that integrated capability isn’t a convenience. It’s what makes the project legally executable from start to finish.
Demolition costs vary based on scope, structure size, and what hazardous materials are present — and in Oyster Bay, the hazardous materials piece is rarely zero. For a standard interior selective demolition like a kitchen or bathroom gut in a pre-1980 home, you’re typically looking at costs that reflect both the physical demolition work and any required asbestos or lead abatement. Full residential structural demolition on a single-family home generally runs in the range of several thousand dollars and up, depending on size, access, and what the pre-demolition assessment turns up.
What shifts the cost most in Oyster Bay specifically is the age and condition of the structure. Homes near the harbor, older colonial or Victorian-era properties, and structures that have been renovated multiple times tend to have more layered materials — which means more to assess and potentially more to abate. The permitting process also adds time, and time affects cost. The most useful thing we can do is walk the property, tell you honestly what’s there, and give you a written scope before any work begins. That way you’re making a decision based on real numbers, not estimates built on assumptions.
