NYS and NYC M/WBE Certified Contractor
A bathroom remodel in North Sea isn’t the same project it would be in an inland suburb. You’re dealing with a coastal environment that works against bathrooms year-round persistent humidity off Little Peconic Bay, salt air that eats through grout and corrodes fixtures faster than most homeowners expect, and freeze-thaw cycles that stress older plumbing every winter. When the renovation is done right, those environmental factors stop being a recurring problem and start being something your bathroom is actually built to handle.
For the roughly one in three North Sea homes that sit vacant for months at a time, the stakes are even higher. Moisture doesn’t wait for you to come back. A slow drip under a vanity, a failing tile surround, or a bathroom with inadequate ventilation can quietly develop into a mold situation over a single off-season. A properly waterproofed, well-ventilated bathroom renovation eliminates that risk not just cosmetically, but structurally. You come back to a bathroom that’s in the same condition you left it.
And if your home was built between 1940 and 1980 which describes a significant portion of North Sea’s housing stock a renovation done by a contractor who can handle what’s behind the walls means you’re not stopping mid-project when something unexpected turns up. You get a finished bathroom, on schedule, without the phone calls and delays that come when a crew isn’t equipped for what older homes actually contain.
Green Island Group is a full-service renovation and restoration contractor based in Suffolk County, with over 5,000 completed projects across New York State. We understand North Sea specifically because we’ve worked on homes throughout the hamlet from North Sea Road down to the waterfront properties along Little Peconic Bay. This community isn’t forgiving for contractors who are still figuring things out. Homes near North Sea Harbor and along the bay-side roads have specific demands coastal materials, moisture management, and older construction that requires more than a standard renovation crew.
What makes us different from the other bathroom remodel companies serving the Southampton area is the combination of capabilities under one roof. We hold EPA-compliant asbestos abatement certification, Lead-Based Paint License LBP-F122209-1, and in-house mold remediation capability. When your 1965 North Sea ranch opens up during demo and the walls tell a different story than the estimate, the project doesn’t stop. It keeps moving.
We also handle insurance claims directly billing carriers, managing the paperwork, and walking homeowners through the process from start to finish. For a community where storm damage and water intrusion are genuine seasonal risks, that’s not a small thing.
It starts with a real assessment. Not a quick walk-through with a clipboard, but an honest look at what your bathroom needs, what the walls and floors might be hiding, and what the project actually involves before a number gets put on paper. In North Sea, that assessment carries extra weight homes built before 1980 routinely contain materials that need to be handled carefully, and a contractor who doesn’t check for that upfront is setting you up for a mid-project delay you didn’t budget for.
Once the scope is clear, permits get pulled through the Southampton Town Building Department. Any bathroom remodel that touches plumbing, electrical, or structural elements requires one, and we manage that process entirely. You don’t have to track down forms, schedule inspections, or follow up with the building department especially important if you’re managing this project from off the island.
From there, demo begins with eyes open. If hazardous materials turn up asbestos tile, lead paint, mold behind the surround they’re handled in-house under the appropriate licenses before the renovation continues. No stopping, no third-party crew to coordinate, no waiting. The renovation work follows: tile, plumbing, electrical, fixtures, waterproofing, and finish work, all done to a standard that holds up in a coastal environment. When the job is done, it’s inspected, signed off, and built to last not just to look good on the day you walk in.

A full bathroom renovation with us covers the complete scope: demo, tile installation, plumbing and fixture upgrades, electrical work, vanity installation, walk-in shower conversions, tub-to-shower conversions, waterproofing systems, and ventilation. For North Sea homes specifically, the waterproofing and moisture management components aren’t optional add-ons they’re central to the project. Cement board substrates, waterproof membrane systems, and properly sealed fixtures are what separate a bathroom that holds up on the bay from one that starts failing within a few years.
For older homes and there are plenty of them between North Sea Road and the water the scope often extends beyond standard renovation work. We hold EPA-compliant asbestos abatement certification and Lead-Based Paint License LBP-F122209-1, which means if your 1960s bathroom has materials that need to be removed carefully, that work happens in-house without pausing the project. Most bathroom remodel contractors in the Southampton market don’t have those credentials. When they find something, they stop. We don’t.
If your renovation is connected to a water damage event or an insurance claim a burst pipe over winter, storm intrusion, or a slow leak that finally got noticed we have documented experience working directly with insurance carriers. We handle the billing, the documentation, and the back-and-forth so you’re focused on the finished bathroom, not the paperwork. For a second-home community like North Sea, where damage often goes undetected between visits, that capability is worth a lot.
It depends on what the project involves. Purely cosmetic updates repainting, swapping a toilet for the same model, replacing a mirror don’t require a permit. But if the remodel touches plumbing, electrical, or anything structural, you need one. That covers most real bathroom renovations: relocating a drain, adding a circuit for new lighting, converting a tub to a walk-in shower, or expanding the bathroom footprint.
In North Sea, permits run through the Southampton Town Building Department, not a village-level authority the hamlet is unincorporated within the Town of Southampton. Basic alteration permits for projects under $50,000 start around $250, with additional fees for electrical and plumbing work. Processing typically takes two to six weeks, and during the spring Hamptons construction season, expect it to run longer. We manage the entire permit process, so if you’re not local or don’t want to deal with the back-and-forth, that’s handled.
Nationally, a midrange bathroom remodel averages around $26,000. In North Sea and the broader Southampton market, that number climbs significantly $40,000 to $70,000 or more is realistic for a midrange renovation, and high-end projects on estate-level properties can go well beyond that. Labor rates on the East End are higher than most of Long Island, permitting adds cost and time, and the material expectations in this market are calibrated to homes worth $1 million or more.
The more useful question is what you get for that investment. A well-executed bathroom remodel recouped roughly 80% of its cost at resale in the 2025 Cost vs. Value Report and in a market where North Sea’s median home sale price recently hit $1.4 million, a bathroom that reads as dated or poorly maintained is a direct drag on perceived value. The renovation pays for itself in more ways than one, as long as it’s done to a standard the home actually demands.
This is one of the most common concerns for North Sea homeowners with older homes and it’s a legitimate one. A significant portion of the hamlet’s housing stock was built between 1940 and 1969, when asbestos floor tiles, pipe insulation, and joint compound were standard materials. Lead-based paint on trim and walls is equally common in pre-1978 construction. When demo opens up those walls and floors, there’s a real probability of finding something that needs to be handled carefully.
Most bathroom remodel contractors in the Southampton area are not licensed to handle hazardous materials. When they find something, the project stops while they locate a specialist, coordinate schedules, and wait for remediation to be completed which can add weeks and thousands of dollars to the job. We hold EPA-compliant asbestos abatement certification and Lead-Based Paint License LBP-F122209-1, and carry licensed mold remediation capability. Everything gets handled in-house, under the appropriate credentials, without stopping the project. The renovation continues on the original timeline, and you’re not managing two separate contractors to get one bathroom finished.
This is a real and practical concern in North Sea, where close to 35% of homes are seasonally occupied. Managing a renovation remotely without being on-site to check progress, field questions, or respond to issues requires a contractor who communicates proactively and doesn’t need to be chased for updates.
We operate with that reality in mind. We manage the permit process through the Southampton Town Building Department, coordinate inspections, handle the scope as it develops, and keep homeowners informed without requiring you to be physically present. If the project is tied to an insurance claim storm damage, a burst pipe, water intrusion discovered when you opened the house after winter we handle the carrier communication and documentation directly. The practical experience of working with second-home owners on the East End means we understand the compressed timelines, the seasonal pressure to finish before summer, and the need for a contractor who runs the project rather than waiting for direction.
For a standard full bathroom renovation demo, tile, plumbing, electrical, fixtures, and finish work the construction phase typically runs two to four weeks once the project is underway. What adds time is everything before the tools come out: permitting, material lead times, and the assessment phase. In North Sea, permits through the Southampton Town Building Department can take two to six weeks for straightforward projects, longer during the busy spring construction season when the Hamptons market is at full volume.
If hazardous materials are discovered during demo, that adds time with most contractors but not with us, since abatement is handled in-house without bringing in outside crews. The most important thing for North Sea homeowners with a seasonal deadline finishing before Memorial Day, or completing the project during the fall off-season is starting the process early enough to account for the permitting timeline. Calling in March to finish before June is tight. Calling in January gives you real runway.
Yes, and it’s one of the more common project types we handle in coastal communities like North Sea. The South Fork is directly exposed to nor’easters, tropical storms, and the coastal flooding and wind-driven rain that come with them. Burst pipes during winter vacancy, water intrusion through failing window seals, and storm surge damage to ground-floor bathrooms are all situations that start as an emergency and end as a full renovation.
What makes us specifically suited for these projects is the combination of restoration experience and renovation capability in one contractor. We’ve completed thousands of water damage and restoration projects across Long Island, which means we know how to assess the full scope of damage not just what’s visible, but what’s been sitting in the walls. We also have direct experience billing insurance carriers and managing the claims process from documentation through final payment. For a North Sea homeowner dealing with a covered loss, that means one point of contact, one contractor, and a finished bathroom without having to coordinate between a restoration crew and a separate remodeling company.
