NYS and NYC M/WBE Certified Contractor
When demolition goes smoothly, everything downstream moves faster. Your builder gets a clean, graded site on the date you were promised. Your permits are closed properly. Your disposal documentation is in hand. And you’re not fielding calls from three different contractors trying to figure out who’s responsible for what.
That matters especially in Northwest Harbor, where the housing stock tells a specific story. The homes that went up in the Northwest Woods area starting in the late 1940s and through the 1970s the Cape Cods, the Ranch homes, the Salt Box bungalows on two- and three-acre wooded lots were built during the peak era of asbestos use in American residential construction. Floor tiles, pipe insulation, roofing shingles, boiler wrap these materials are common findings in pre-1980 homes here. A demolition contractor who isn’t licensed to survey and abate those materials legally can’t move forward until you bring in a separate environmental firm. That gap costs weeks and creates real coordination risk when you have a builder scheduled.
We hold the NYS Department of Labor Asbestos Contractor License, which means the survey, the abatement if it’s needed, and the full structural demolition all happen under one contract. For property owners managing an estate, a teardown-rebuild, or a sale from a distance which describes a significant portion of Northwest Harbor’s ownership base that single point of accountability is what makes the difference between a project that moves and one that stalls.
Green Island Group is a full-service demolition and environmental contractor serving Long Island and the New York metro area, including Northwest Harbor and the South Fork communities under East Hampton Town’s jurisdiction. The licenses that matter for a Northwest Harbor demolition NYS DOL Asbestos Contractor, Suffolk County Home Improvement Contractor, EPA Lead RRP Certification, NYS DOL Mold Remediation are all current, verifiable, and public record. If your attorney or your builder wants to check them, that’s encouraged.
Working in East Hampton Town is different from working in most of Suffolk County. The Building Department has its own permit portal, its own clearing envelope requirements, and a permit timeline that routinely runs six months to a year on major projects. Properties near Gardiners Bay, Three Mile Harbor, and the area’s creek inlets often require a wetlands review before a demolition permit is issued. These aren’t surprises to us they’re part of the process we navigate on every project in this area.
Government agencies and municipalities have contracted with us after conducting their own background checks, insurance reviews, and license verifications. That track record doesn’t happen without consistently delivering what we promised.
The first conversation is straightforward. You tell us what you’re working with the structure, the lot, the timeline, any known history of the property and we assess what the project actually requires. For most homes in the Northwest Woods area, that means scheduling a pre-demolition asbestos survey before anything else moves forward. New York State requires it by law, and the East Hampton Town Building Department expects it as part of the permit process. We handle the survey, document the findings, and give you a clear scope before work begins.
From there, we prepare and submit the permit application through East Hampton Town’s OpenGov portal. If your property is near the water along Gardiners Bay, Three Mile Harbor, or any of the inlets in the area we flag the wetlands review requirement early, because that step has its own timeline and missing it is one of the most common reasons demolition projects in Northwest Harbor get delayed. We also coordinate utility disconnections with the relevant providers, which must be formally signed off before demolition can begin.
Once permits are issued and utilities are cleared, the structural demolition proceeds. All debris is removed and disposed of at licensed facilities, and you receive complete disposal documentation which is required for permit closeout with the East Hampton Town Building Department. The site is graded and left clean. Your builder can move in.

A full house demolition in Northwest Harbor isn’t just tearing down a structure. It’s a sequenced process with regulatory steps that have to happen in the right order and in East Hampton Town, that sequence is more involved than most of Long Island. The pre-demolition asbestos survey is required before the permit application. The clearing envelope survey, prepared by a licensed surveyor and showing the limitations on what can be disturbed on your lot, has to be submitted with the permit. If the property is on the Town’s wetlands inventory which applies to a meaningful number of Northwest Harbor properties given the area’s coastal geography a wetlands permit or letter of non-jurisdiction from the Environment Division is required before the Building Department will issue the demolition permit.
We manage all of it. The asbestos survey and abatement if needed, the full structural demolition, debris removal, licensed disposal with complete documentation, and site grading. If asbestos isn’t the only finding lead paint and mold are also common in the pre-1980 homes that make up much of Northwest Harbor’s housing stock we hold the licenses to address those as well, without requiring you to bring in a separate contractor.
For estate trustees, absentee owners, and developers working through a teardown-rebuild on a tight construction schedule, the value of a single contract covering every phase isn’t abstract. It’s the difference between your project closing on time and your builder sitting idle while you track down a second vendor.
Yes no demolition can legally begin in Northwest Harbor without a permit issued by the East Hampton Town Building Department. The application is submitted through the Town’s OpenGov online portal, and it requires more supporting documentation than most Long Island municipalities ask for. You’ll need a staked survey prepared by a licensed surveyor that shows the clearing limitations what’s called the clearing envelope for your specific property. That’s an East Hampton Town-specific requirement that contractors unfamiliar with this jurisdiction routinely miss, which causes delays.
Depending on where your property sits in Northwest Harbor, you may also need a wetlands permit or a letter of non-jurisdiction from the Town’s Environment Division before the Building Department will issue the demolition permit. Northwest Harbor’s proximity to Gardiners Bay, Three Mile Harbor, and the area’s creek inlets means a significant number of properties are on the Town’s wetlands inventory. It’s worth identifying that early, because the wetlands review has its own timeline and it runs concurrently with, not after, the permit process. East Hampton Town permit timelines for major projects typically run six months to a year from application to issuance. That’s not a reason to panic, but it is a reason to start the process earlier than you think you need to.
Yes, and it’s not optional. New York State law requires a licensed asbestos survey before any demolition activity, regardless of the structure’s size or apparent condition. This applies to every home in Northwest Harbor including properties that look fine on the outside. The homes built in the Northwest Woods area starting in the late 1940s and through the 1970s were constructed during the peak era of asbestos use in American residential construction. Floor tiles, pipe insulation, roofing shingles, exterior siding, joint compound, boiler wrap these are all common asbestos-containing materials in homes from that period, and they’re found regularly in pre-1980 Northwest Harbor properties.
The survey has to be conducted by a licensed asbestos inspector. If asbestos-containing materials are found, abatement must be performed by a contractor holding the NYS Department of Labor Asbestos Contractor License before demolition can proceed. We hold that license, which means the survey, the abatement if it’s needed, and the structural demolition all happen under one contract. You’re not coordinating between an environmental firm and a demolition contractor and you’re not losing weeks to a handoff that doesn’t happen on schedule.
Full house demolition in the New York metro area typically ranges from $20,000 to $60,000, depending on the size of the structure, what hazardous materials are found, site access conditions, and disposal costs. In Northwest Harbor specifically, a few factors can push costs toward the higher end of that range. The homes here tend to sit on large lots two to three acres or more with long driveways and mature tree cover, which affects equipment access and debris removal logistics. Pre-1980 construction is common, which means asbestos abatement is a realistic line item rather than a long shot. And East Hampton Town’s permit process involves fees and supporting documentation that add to the front-end cost of the project.
That said, the cost of demolition in this market is almost always a small fraction of the total project value. When a Northwest Harbor property is worth $1.3 million at median and new construction on a cleared lot can reach $5 to $10 million the risk of hiring an underqualified contractor to save a few thousand dollars is not a trade-off that makes financial sense. A stop-work order, an EPA violation for improper asbestos disposal, or a delayed construction start because permits weren’t handled correctly all cost more than the difference between a qualified contractor and a cheap one.
The demolition itself the actual structural teardown typically takes one to three days for a standard residential structure, depending on size. But the full project timeline, from initial assessment to clean site, is driven almost entirely by the permit process, and East Hampton Town’s permit timeline is one of the longest on Long Island. For major projects, you should plan for six months to a year from permit application to issuance. That’s not an exaggeration, and it’s not a knock on the Town it reflects a thorough review process that includes the Building Department, the Environment Division for wetlands-adjacent properties, and the staked survey requirement.
The practical implication is that if you’re planning a teardown-rebuild in Northwest Harbor and you have a builder scheduled, you need to start the permit process significantly earlier than your intuition tells you to. The pre-demolition asbestos survey, the staked survey, the wetlands review if applicable, and the permit application all need to be in motion well before your target demolition date. We initiate that process at the start of every project not after the contract is signed and the calendar is already tight.
You can sell a lot after demolition, and in Northwest Harbor’s real estate market, a cleared lot with a closed demolition permit is a straightforward and often attractive listing. Buyers in this market developers, investors, and affluent individuals executing teardown-rebuild strategies are comfortable purchasing cleared land when the permitting history is clean and the site is properly documented. What matters to those buyers is that the demolition was done compliantly: licensed asbestos abatement, proper debris disposal with documentation, and a formally closed permit from the East Hampton Town Building Department.
A permit that was never closed, or disposal that wasn’t properly documented, creates title and liability exposure that can complicate or kill a sale. We provide complete disposal manifests for all hazardous materials removed from the site and coordinate permit closeout with the East Hampton Town Building Department as a standard part of every project. If you’re planning to list the property after demolition, that documentation is what your real estate attorney and any serious buyer’s counsel will ask for and it’s ready when you need it.
Finding asbestos or mold during the pre-demolition survey is not a project-ending event it’s a normal part of working with pre-1980 housing stock in Northwest Harbor, and it’s exactly why the survey happens before demolition begins rather than during it. When asbestos-containing materials are identified, a licensed abatement contractor removes and disposes of them according to NYS DOL protocols before structural demolition proceeds. The abatement scope, the disposal manifests, and the clearance documentation all become part of the project record.
Mold is a separate but equally manageable finding. Northwest Harbor properties that have been seasonally occupied or that have sat vacant through a few winters near the water can develop mold in walls, crawl spaces, and below-grade areas. We hold the NYS DOL Mold Remediation License in addition to the Asbestos Contractor License, which means both findings are handled by the same contractor without stopping the project to bring in a separate firm. For estate properties and absentee-owned homes in particular which represent a significant share of Northwest Harbor’s ownership base having one contractor who can legally address whatever is found, without requiring the owner to manage a handoff between vendors, is the most practical way to keep the project moving on schedule.
