NYS and NYC M/WBE Certified Contractor
Mastic Beach homes take a beating. The salt air off the Great South Bay, the humidity that never fully lets up, and the flood history that comes with living in a community where over half of properties carry serious flood risk all of it adds up inside your walls, under your floors, and behind your tile. A bathroom remodel done right here isn’t just about aesthetics. It’s about building something that holds up to the conditions you actually live in.
When you work with a contractor who understands the coastal environment and the age of the housing stock in this area, you get materials selected for real-world performance waterproof membranes, cement board substrates, properly sized ventilation not just whatever looks good in a showroom. That matters in a 1960s bungalow off William Floyd Parkway a lot more than it does in a new build somewhere inland.
And if your remodel is connected to water damage, mold, or an insurance claim, the outcome looks different too. You’re not just getting a renovated bathroom you’re getting a bathroom that replaced a problem, documented properly, done without stopping mid-job because someone wasn’t certified to handle what they found.
We’re based out of Bohemia about 20 minutes from Mastic Beach via Sunrise Highway and have completed over 5,000 restoration and remodeling projects across New York State. That’s not a number pulled from thin air. It means our team has seen what post-war South Shore homes actually look like when you open them up, and we know how to keep a project moving when the unexpected shows up.
What makes Green Island Group different from most bathroom remodel companies serving the 11951 area is the combination of licenses we carry. We’re a licensed home improvement contractor and a certified asbestos and mold remediator. If demolition turns up a hazardous material which happens more often than most contractors will admit in homes this age we handle it in-house and keep the project on track.
We also work directly with insurance carriers. If your remodel is tied to a flood claim or storm damage, we’ve been through that process hundreds of times and know how to document it correctly from day one. In Mastic Beach specifically, where flooding has been a recurring issue for residents, this expertise makes a real difference in how smoothly your project moves from claim approval to finished bathroom.
It starts with a site visit. Before any numbers are discussed, someone comes out to look at the bathroom not just the surface, but the condition of the subfloor, the ventilation, the plumbing layout, and any visible signs of moisture or prior damage. In Mastic Beach, that walk-through matters more than it does in most places. Homes in this area have a history, and a good contractor looks for it before committing to a scope.
From there, you get a detailed estimate line by line, no vague ranges. If the project requires a building permit through the Town of Brookhaven Building Division, we pull it. If the work involves plumbing changes, electrical modifications, or anything that touches the structure, the permit gets filed before the first tile comes off the wall. That protects you when it’s time to sell and keeps the job legally clean from start to finish.
Once work begins, the process runs in a logical sequence: demo, inspection of what’s underneath, any remediation that’s needed, rough plumbing and electrical, waterproofing, tile and fixtures, and final trim. If something unexpected comes up during demo and in a pre-1980 Mastic Beach home, it sometimes does you hear about it immediately, with a clear explanation of what it is, what it costs to address, and what happens next. No guessing, no stalling.

A full bathroom remodel with us covers everything from demolition to the final walk-through and in Mastic Beach, that often includes things other contractors aren’t equipped to handle. Asbestos floor tiles, lead paint on trim, mold behind the shower wall these are real findings in this housing stock, and they require certified removal before renovation can continue. We hold active asbestos abatement certification and lead abatement certification (LBP-F122209-1), so when those materials show up, the job doesn’t stop.
On the construction side, the scope typically includes subfloor repair or replacement, waterproof membrane installation, cement board substrate, tile and grout, fixture installation, vanity and cabinetry, plumbing rough-in and finish work, electrical updates including GFCI outlets, ventilation fan sizing and installation, and all finish trim. For homes in FEMA AE or VE flood zones which covers a significant portion of Mastic Beach we factor flood-resistant material specifications into the build from the start, not added as an afterthought.
If you’re updating a bathroom for accessibility grab bars, a walk-in shower conversion, a comfort-height toilet we handle that too. And if your project is insurance-funded, we bill carriers directly and manage the documentation so you’re not stuck in the middle between your adjuster and your contractor.
Yes, in most cases. Since the Village of Mastic Beach dissolved in 2016, all building permits and inspections are handled by the Town of Brookhaven Building Division. If your bathroom remodel involves any changes to plumbing lines, electrical circuits, or the structure of the space which most full renovations do a permit is required under Brookhaven Town Code Section 16-3 and the New York State Uniform Fire Prevention and Building Code.
This matters more than people realize. Unpermitted work can create real problems when you go to sell your home. A buyer’s attorney or inspector will flag open permits or work done without sign-off, and it can delay or kill a closing. We pull all required permits before work begins, schedule the inspections, and get the certificate of occupancy at the end. You don’t have to navigate the Brookhaven Building Division on your own.
It depends on your contractor. For most remodeling companies, finding asbestos tile under the vinyl floor or mold behind the shower wall means the job stops they’re not certified to touch it, so they have to bring in a separate remediation firm. That means delays, additional contracts, and a gutted bathroom sitting open while you wait for scheduling to align between two different companies.
We hold active asbestos abatement certification and lead abatement certification (LBP-F122209-1), and mold remediation is a core part of what we do. If something turns up during demo, we handle it in-house and keep the project moving. In Mastic Beach specifically, where the housing stock is largely 1950s and 1960s construction and flood history has created conditions for recurring mold growth, this isn’t a hypothetical edge case it’s a realistic scenario on a meaningful percentage of full gut renovations.
The honest answer is that it depends on the scope, the condition of what’s underneath, and what materials you choose. Local competitors in the Mastic Beach area have quoted bathroom renovation ranges of $15,000 to $35,000 for a standard full remodel. Long Island pricing runs 30 to 50 percent above national averages due to labor costs, material pricing, and permit requirements so national cost guides will typically underestimate what you’ll spend here.
What affects the number most is what’s discovered during demo. If the subfloor is rotted, if there’s mold behind the tile, or if the plumbing hasn’t been touched since the home was built, those are real costs that have to be addressed before anything new goes in. A contractor who gives you a very low number upfront without doing a thorough site assessment is likely leaving those discoveries out of the estimate. We provide detailed, line-item estimates after a proper walk-through so what you see at the start is as close as possible to what you pay at the end.
Yes, and it’s more common in Mastic Beach than most contractors will tell you. With 54 percent of properties in this area carrying a major flood risk rating and the community’s history going back to Hurricane Sandy in 2012, a significant number of bathroom remodel projects here are tied to a prior flood event sometimes one that happened years ago and was never fully remediated.
If you have an active insurance claim through your homeowner’s policy or NFIP flood insurance we can work directly with your adjuster. We document the damage, provide the scope of work in the format carriers require, and bill the insurance company directly for covered portions of the project. Where the remodel goes beyond what insurance covers, we clearly separate those costs so you know exactly what you’re paying out of pocket. You don’t need to figure out the insurance side on your own while also trying to manage a renovation.
A standard full bathroom remodel typically runs two to four weeks once work begins, assuming no major surprises during demolition. The permit process through the Town of Brookhaven adds time on the front end plan for that in your timeline, not as an afterthought. Inspection scheduling through Brookhaven can add a few days at key milestones, so a realistic project timeline from signed contract to finished bathroom is usually six to eight weeks when you factor in permitting, material lead times, and inspections.
What extends timelines most often is the discovery of conditions that weren’t visible before demo started rotted subfloor, mold remediation, or plumbing that needs to be reconfigured. In Mastic Beach homes, especially those that have experienced any degree of water intrusion over the years, these discoveries happen. We communicate immediately when something changes the scope, so you’re never sitting in the dark wondering why the job slowed down.
Yes. We’re headquartered in Bohemia, roughly 20 to 25 minutes from Mastic Beach via Sunrise Highway and William Floyd Parkway. We’ve been serving Suffolk County homeowners for years and are familiar with the Town of Brookhaven’s permitting process, the coastal construction conditions that affect South Shore homes, and the specific challenges that come with renovating in Mastic Beach where the housing stock is older, flood exposure is real, and many projects involve more than a straightforward cosmetic update.
We already serve the 11951 zip code and the surrounding communities of Shirley, Mastic, and the broader Brookhaven area. That means our crew knows the area, our project managers can make site visits without significant travel overhead, and we operate within the same regional contractor network local suppliers, local subcontractors, and familiarity with what South Shore homes actually look like from the inside.
