NYS and NYC M/WBE Certified Contractor
There’s a big difference between a basement that looks dry and a basement that is dry. Water wicks into wall cavities, underneath flooring, and behind insulation invisible to the eye but actively causing damage. Mold starts growing within 24 to 48 hours. By the time you can smell it, you’re already looking at a much bigger problem than what you started with.
For homes in North Patchogue most of them built between the 1940s and 1960s that hidden moisture problem runs even deeper. Older construction means less waterproofing, aging pipe systems, and insulation that was never designed to handle a flood. When water gets behind those walls, it doesn’t just sit there. It works its way into the structure of the house, and what started as a few inches of standing water becomes a mold remediation job, a structural repair, or worse.
What you get when this is handled right is a basement that’s been dried with professional-grade equipment, tested for hidden moisture with thermal imaging, and cleared for safety not just mopped out and left. That means no mold surprise six weeks from now, no second contractor, and no wondering whether the job was actually finished.
Green Island Group is a locally owned environmental restoration company led by CEO Jessica Dussan and VP Leo Torres. We’ve completed more than 5,000 restoration projects across New York State, and we hold every license that matters for this kind of work in Suffolk County including a NYS DOL Mold license, NYS DOL Asbestos license, USEPA Lead certification, and a Suffolk County General Contractor license.
That last part matters more in North Patchogue than most places. The homes here were built in an era when asbestos insulation and lead paint were standard. When a basement floods and walls get disturbed, those materials don’t stay put. Most water damage companies operating in this area are not licensed to handle what they might find. We are legally, and with the equipment to back it up.
We’re also an approved emergency response contractor for the NYS Office of General Services, independently certified as a Minority Business Enterprise and Woman-Owned Business Enterprise by New York State. This isn’t a franchise. There’s no call center. When you reach out, you’re reaching a real company with real people who are accountable for the outcome.
The first call triggers a same-day response. Our team arrives typically within an hour to assess the situation before anything else happens. That assessment matters because not all basement flooding is the same. Water from a burst pipe is one category. Water that backed up through a drain connected to an aging municipal system near the Patchogue River watershed is another. The source determines the protocol, and getting that wrong creates health risks that don’t show up until later.
Once the source is identified and contained, extraction begins using commercial-grade equipment not shop vacs, not consumer pumps. Industrial air movers and dehumidifiers go in immediately after to start the structural drying process. Thermal imaging checks for moisture inside wall cavities and under flooring that you can’t see from the surface. In homes built in the 1940s and 1960s, this step is especially important older construction holds water in places that newer builds don’t.
If the assessment turns up mold, asbestos-containing materials, or lead paint which is a real possibility in North Patchogue’s housing stock we handle it under the same roof. No second contractor, no handoff, no gap in accountability. Once everything is dry, tested, and cleared, any structural repairs needed are handled under our Suffolk County General Contractor license. You get a full scope of work documented for your insurance claim, and we bill your carrier directly.

Flooded basement cleanup in North Patchogue isn’t a one-size situation. The scope of what’s needed depends on the water source, how long it sat, what’s behind the walls, and what the structure is made of. We cover the full range emergency water extraction, structural drying, moisture testing, mold remediation, hazmat abatement, and full reconstruction all under one contractor.
For homes near Canaan Lake and the surrounding streets, where drainage issues have caused documented, recurring flooding problems, the work often goes beyond surface cleanup. Waterways feeding Canaan Lake have backed up during heavy rainfall events, pushing water into basements in the Newman Street area and nearby blocks. That kind of flooding can carry contaminants that require Category 3 blackwater protocols proper containment, antimicrobial treatment, and licensed disposal. We’re equipped and licensed to handle it.
Every job includes direct insurance billing. Our team documents the damage, communicates with your adjuster, and submits the claim so you’re not stuck navigating that process while your basement is still wet. Suffolk County building permits for any structural work are handled as part of the process, keeping everything above board with the Town of Brookhaven’s requirements. Whether it’s a pipe burst at 2 AM or post-storm flooding after a nor’easter rolls through, the response and the scope are the same.
It depends on what caused the flooding, and that distinction matters a lot. Standard homeowners insurance typically covers sudden, internal water damage a pipe that burst, a water heater that failed, a washing machine hose that gave out. What it generally does not cover is water that entered from outside, like groundwater backing up through your foundation or floodwater from a storm event. For that type of coverage, you’d need a separate flood insurance policy through the National Flood Insurance Program.
In North Patchogue, this distinction is especially relevant. Homes near Canaan Lake and the Patchogue River watershed have experienced flooding tied to drainage system failures and heavy rainfall events the kind of water intrusion that often falls into the external flood category. If you’re not sure what your policy covers, we document the cause and source of the water damage as part of the initial assessment, which is exactly what your adjuster will need to process the claim. We bill your insurance directly and handle that communication so you don’t have to figure it out while your basement is still underwater.
Mold can begin developing within 24 to 48 hours of a flooding event sometimes faster in warm, humid conditions. Once it takes hold inside wall cavities or underneath flooring, it doesn’t stop on its own. By the time it’s visible or you can smell it, you’re typically looking at a remediation job on top of the original water damage cleanup, which adds significant cost and time to the project.
The reason this matters so much in North Patchogue specifically is the age of the housing stock. Homes built in the 1940s through 1960s often have materials wood framing, plaster walls, older insulation that absorb and hold moisture far more readily than modern construction. That moisture stays trapped long after the visible water is gone, creating ideal conditions for mold growth inside the structure. Professional drying with commercial-grade dehumidifiers and air movers, combined with thermal imaging to find hidden moisture, is the only reliable way to stop that clock. Acting within the first 24 hours makes a measurable difference in both the scope of work and the final cost.
Canaan Lake is a 26-acre, shallow man-made lake sitting at just 25 feet of elevation in the middle of a residential neighborhood. When heavy rainfall hits or when the waterways feeding and draining the lake get clogged, which has happened due to invasive aquatic plant growth water has nowhere to go. It backs up into the surrounding neighborhood, and the streets closest to the lake, including the Newman Street area, have experienced what local legislators described as significant, recurring flooding problems.
Beyond the lake itself, North Patchogue sits within the broader Patchogue River watershed, which drains into Patchogue Bay and the Great South Bay. That entire system is sensitive to sustained rainfall, storm surge, and tidal backup during major weather events. Add in Long Island’s naturally high water table which rises further during wet seasons and you have a community where basement flooding isn’t a rare event. It’s a real, recurring risk that the housing stock, most of it built before modern waterproofing standards existed, wasn’t designed to handle.
For a small amount of clean water from a known source like a supply line that burst a homeowner can manage initial cleanup if they act fast. But in most flooding scenarios, especially in North Patchogue, DIY cleanup carries real risks that aren’t obvious until it’s too late. The first is hidden moisture. Without thermal imaging and professional moisture meters, you won’t know what’s still wet inside the walls. That moisture becomes mold in a matter of days.
The second risk is specific to this area’s housing stock. Homes built in the 1940s through 1960s which make up the majority of North Patchogue frequently contain asbestos insulation and lead paint. When a flood disturbs those materials, you can be exposed to hazardous substances without realizing it. Disturbing asbestos-containing materials without proper licensing and containment is not just dangerous it’s illegal in New York State. We hold both the NYS DOL Asbestos license and USEPA Lead certification required to handle these situations legally and safely. If there’s any question about what’s behind your walls, the safe call is to bring in someone who’s licensed to find out.
The range is wide because the scope varies significantly depending on the cause, the size of the affected area, and what’s found during the assessment. For a straightforward water extraction and structural drying job with no mold or hazmat involvement, costs typically fall somewhere between $2,000 and $5,000. If mold remediation is needed, or if asbestos or lead materials are disturbed and require abatement, the total can climb to $8,000 or more.
In North Patchogue, where many homes are 60 to 80 years old and where drainage issues near Canaan Lake can send contaminated water into basements, jobs that initially look simple sometimes reveal additional layers once the walls are opened. That’s why we provide a documented estimate after the initial assessment, bill your insurance directly, and don’t add surprise line items after the work starts. Knowing your actual costs upfront, and having someone handle the insurance side of it, takes most of the financial uncertainty out of the process.
Yes and in North Patchogue, that capability matters more than it might in a newer community. Mold remediation in New York State is regulated under NYS Labor Law Article 32, which requires that both assessment and remediation be performed by licensed professionals. We hold the NYS DOL Mold license required by that law, which means the work is done legally and the documentation holds up for your insurance claim and any future home sale.
What makes this especially relevant here is that mold remediation after a basement flood isn’t always a separate job that comes weeks later. In homes with older construction the kind that dominates North Patchogue mold can establish itself inside wall cavities and underneath flooring faster than most people expect. Handling water extraction, structural drying, and mold remediation under one contractor means there’s no gap between the cleanup crew leaving and the mold crew arriving. The assessment, the drying, the testing, and the remediation are all part of the same continuous process, which is both faster and more thorough than splitting the work between multiple companies.
