NYS and NYC M/WBE Certified Contractor
Most basements in St. James look fine within a day or two of a flood. The floor dries, the water recedes, and it seems like the worst is over. It isn’t. Water wicks into wall cavities, underneath flooring, and inside insulation and within 24 to 48 hours, mold starts growing in places you can’t see. By the time you can smell it, the remediation cost has already multiplied.
That’s why the outcome you’re actually paying for isn’t just water removal it’s confirmation that your home is structurally dry and safe. We use moisture meters and thermal imaging to verify what a visual inspection misses entirely. You get a clear picture of what happened, what was affected, and what was done about it.
Here in St. James, that matters more than it does in a lot of other places. The housing stock is older the median construction year is 1973, and a meaningful portion of homes predate 1950. Older foundations, aging waterproofing, and decades of settled infrastructure mean water finds its way in through paths that newer construction simply doesn’t have. When we finish, you’re not just dry. You know you’re dry.
Green Island Group is an environmental restoration and remediation company serving Suffolk County, Nassau County, Queens, and New York City. We’ve completed more than 5,000 restoration projects across New York State, and we hold the full licensing stack required to legally handle every phase of post-flood work including the phases most companies can’t touch.
That matters in a community like St. James. Homes near Stony Brook Harbor, older properties along 25A, and the 653 homes inside Fairfield at St. James all carry the same risk: when water damage requires drywall removal or floor demolition, you may be dealing with asbestos in pipe insulation or lead paint in the walls. We hold NYS DOL Mold, NYS DOL Asbestos, USEPA Lead, and USEPA RRP certifications so nothing stops mid-job because we hit something unexpected.
We’re also a New York State OGS Approved Emergency Response Contractor and a state-certified MBE and WBE. Those aren’t marketing lines they’re independent verifications that someone other than us has already checked our credentials. CEO Jessica Dussan and VP Leo Torres lead every project with that standard of accountability.
When you call, we respond 24 hours a day, including during active storm events. We’ve shown up within an hour of being called to St. James homes, and that response time is confirmed in real customer reviews, not just claimed in our marketing. The first thing we do when we arrive is assess the full scope of water intrusion using moisture meters and thermal imaging. We don’t start pulling materials until we know exactly what we’re dealing with.
From there, we extract standing water and set up industrial drying equipment to begin structural drying. In an older St. James home, this phase requires more care than it does in newer construction we’re working around materials that may contain asbestos or lead, and we follow proper containment and handling protocols from the start. If hazardous materials are identified, we handle abatement in-house under our NYS DOL licenses. You don’t need to call a second company.
Once the structure is confirmed dry by instrument not by eye we move into mold remediation if needed, followed by reconstruction. We hold a Suffolk County General Contractor license, so we can take your basement from flooded to fully restored under a single contract. We also handle insurance documentation directly, communicating with your adjuster and billing the carrier so you’re not managing that process on top of everything else.

A flooded basement in St. James isn’t always a simple water extraction job. The combination of older housing stock, North Shore clay soils that drain slowly, and a water table that rises near Stony Brook Harbor means flooding here tends to be thorough and the damage it leaves behind tends to go deeper than it looks. Every job we take on is scoped to what your specific home actually needs, not a pre-packaged tier that may leave gaps.
For most residential flooding in St. James whether it’s from a burst pipe, a failed sump pump during a nor’easter, or the kind of torrential rainfall that overwhelmed drainage systems across the Town of Smithtown in August 2023 our process covers water extraction, structural drying, moisture verification, and mold inspection. If mold remediation is required, we handle it under our NYS DOL Mold license. If your home is pre-1978 and we encounter lead paint during demo, or pre-1980 materials with asbestos in floor tiles or pipe wrap, we handle abatement in-house. No subcontractors, no delays.
We also handle sewage backup cleanup, which requires a different protocol entirely. Category 3 water water that has contacted ground or sewer systems is a health hazard, not just a mess. We follow IICRC S500 standards for containment, PPE, and licensed disposal. If you’re not sure what category your flooding falls into, that’s exactly the kind of question we answer on the first call.
It depends on the source of the water, and this is one of the most important questions to get right before you assume you’re covered or that you’re not. Standard homeowners insurance typically covers sudden and accidental water damage from internal sources: a burst pipe, a failed water heater, an appliance that overflows. It does not cover flooding from external sources like groundwater, storm surge, or surface water entering your home that requires a separate flood insurance policy.
Here in St. James, this distinction trips a lot of people up. Because the community isn’t traditionally thought of as a flood zone, many homeowners don’t carry separate flood insurance. The August 2023 storm made that gap very real a local family whose basement flooded completely to the ceiling had no flood insurance specifically because, as they put it, “this area isn’t usually a flood zone.” If your basement flooded from heavy rainfall overwhelming your drainage or entering through foundation walls, your standard policy may not respond. That said, proper documentation of the damage detailed photos, moisture readings, line-item estimates is what gives you the best possible chance with any claim. We handle that documentation process directly and communicate with your adjuster on your behalf.
Mold can begin establishing within 24 to 48 hours of a water intrusion event and Long Island’s humidity levels in the spring and summer accelerate that timeline. By the time most homeowners have made a few calls, gotten a callback, and scheduled someone to come out, the conditions for mold growth are already in place.
What makes this especially relevant in St. James is that a lot of basements here are finished spaces. Carpet, drywall, insulation, and wood trim create the exact environment mold needs. And because water wicks laterally through wall cavities and vertically through flooring, the affected area is almost always larger than what’s visible. Waiting even 72 hours to begin professional drying can add thousands of dollars in mold remediation costs on top of the original water damage. We use thermal imaging and moisture meters to identify the full extent of saturation including areas that look dry but aren’t so remediation is scoped accurately from the start.
For minor flooding from a clean water source say, a small pipe drip that you caught quickly you may be able to manage it with a wet vac and fans if the area is small and unfinished. But for anything beyond that, the risks of a DIY cleanup in a St. James home are real enough that it’s worth understanding before you start pulling up flooring.
In New York State, mold remediation above 10 square feet requires a licensed mold remediator that’s not optional, and it applies to residential properties. If your home was built before 1978, disturbing drywall or flooring without proper lead paint protocols can create a health hazard and a legal liability. If your home was built before 1980, pipe insulation, floor tiles, and HVAC duct tape may contain asbestos materials that are released into the air during demolition if not properly handled. These aren’t edge cases in St. James; roughly 13 to 14 percent of the housing stock here predates 1950, and the median construction year is 1973. A DIY cleanup that disturbs those materials without proper containment can turn a water damage problem into an environmental remediation problem. The cost difference is significant.
The honest answer is that cost varies significantly based on the source of the water, the size of the affected area, and what’s found behind the walls. A straightforward water extraction and structural drying job in an unfinished basement might run $2,000 to $5,000. Once you add mold remediation, that range typically climbs to $5,000 to $15,000 or more depending on how far the growth has spread. If asbestos or lead is identified and requires abatement, that adds cost but it’s a necessary cost, and it’s far less than the liability of leaving it unaddressed.
In St. James specifically, the finished basement factor is important. A lot of homes here have basements that were converted into living spaces over the decades recreation rooms, extra bedrooms, home offices. When a finished basement floods, you’re not just paying for drying equipment. You’re paying for drywall removal and replacement, flooring restoration, and potentially mold remediation in wall cavities that were sealed for years. That scope is what drives cost up, and it’s why documentation matters: a well-documented claim gives your insurance carrier a clear picture of the full scope, which is your best tool for maximizing what they cover.
Yes for any structural work, drywall replacement, or reconstruction following water damage, you’ll need a permit from the Town of Smithtown Building Department. St. James is an unincorporated hamlet within the Town of Smithtown, so all building permits for the area are issued through that office. This applies to reconstruction work, not just the initial cleanup and drying phase.
This is one of the reasons it matters to hire a licensed general contractor rather than just a cleanup crew. We hold a Suffolk County General Contractor license, which means we can pull the necessary permits and execute the full scope of reconstruction legally and in compliance with Town of Smithtown requirements. Homeowners who hire unlicensed contractors for post-flood reconstruction or who try to manage the reconstruction themselves without permits can face issues when they go to sell the home or file a future insurance claim. In a market where the median home value in St. James is approaching $690,000, that’s not a risk worth taking to save a few dollars upfront.
St. James has a specific combination of factors that makes it a community we’re genuinely equipped to serve well and that most restoration companies operating in this market aren’t fully prepared for. The older housing stock, the North Shore flooding pattern driven by clay-heavy soils and proximity to Stony Brook Harbor, and the documented history of intense rainfall events in the Town of Smithtown all create a demand for a contractor who can handle the full scope of what post-flood work here actually involves.
Most water damage companies can extract water and run drying equipment. Far fewer hold the NYS DOL Mold and Asbestos licenses, the USEPA Lead and RRP certifications, and the Suffolk County General Contractor license required to legally handle everything that shows up in a pre-1980 St. James home during a flood restoration job. When a homeowner in Fairfield at St. James or along the older streets near the 25A corridor calls us, they’re not getting handed off to a subcontractor when something unexpected turns up. We handle it start to finish, under one contract, with direct insurance billing and a licensed team that knows exactly what they’re doing in this community.
