NYS and NYC M/WBE Certified Contractor
A bathroom remodel in Sagaponack isn’t the same project it is twenty miles inland. The Atlantic exposure here the salt air off Gibson Beach, the moisture that works its way into building envelopes along Daniels Lane accelerates wear on materials that would last decades anywhere else. When a remodel is done right, you stop replacing caulk every season. You stop finding mildew behind the vanity. The bathroom holds up the way the investment demands it to.
For older homes on streets like Parsonage Lane or Hedges Lane, there’s another layer entirely. Pre-1980 construction in Sagaponack means there’s a real chance demo uncovers asbestos tile or lead paint behind the walls. Most remodelers stop the job when that happens. We don’t because we hold the abatement licenses to handle it in-house and keep the project moving. That matters when your Memorial Day deadline isn’t negotiable.
The end result isn’t just a renovated bathroom. It’s a space that reflects what the property is worth, built with materials and methods that actually hold up to where you live and finished by a contractor who understood the assignment from day one.
Green Island Group is a Suffolk County-based contractor with over 5,000 completed projects across New York State. We’re not a general handyman service that dabbles in remodeling we’re a licensed remodeling and environmental restoration company, which means we bring a level of technical depth to bathroom renovations that most contractors in this market simply don’t have.
What makes us different in a place like Sagaponack is the combination. We handle the design and build side of a bathroom renovation and the hazmat side asbestos abatement, lead abatement, mold remediation under one roof, one contract, and one accountable team. No stopping the job to call in a specialty crew. No second invoice for something that should have been anticipated.
We’ve worked throughout the East End and understand what Sagaponack construction actually looks like from the inside out. Whether it’s a farmhouse off Sagg Road or an oceanfront estate near Wölffer Estate, we know what to expect and we know how to deliver. We understand the Village of Sagaponack’s building code, the coastal zone regulations that apply to oceanfront properties, and the specific challenges that come with renovating homes in a village where the ocean is never more than a mile away.
It starts with a real assessment not a quick walkthrough where someone eyeballs the tile and throws out a number. We look at the full scope: what’s visible, what’s likely behind the walls given the age and location of the property, and what the coastal environment has done to the substrate over time. For Sagaponack properties near the ocean, moisture mapping matters before a single fixture gets pulled.
From there, we handle permitting through the Village of Sagaponack’s Building Inspector not the Town of Southampton’s department. That’s a distinction a lot of contractors miss, and it creates delays that shouldn’t happen. We manage the application, coordinate inspections, and make sure the project is compliant with the Village Code, including any Coastal Erosion Hazard Area requirements that apply to your property.
Demo comes next, and this is where our dual licensing matters most. If we open a wall in a pre-1980 home and find something that needs abatement, we handle it and keep going. No project pause. No scrambling for a second contractor. Once the space is cleared and confirmed clean, the build phase proceeds substrate, waterproofing, tile, fixtures, and finish all executed to a standard that matches what your property is worth. We work backward from your timeline, whether that’s a spring completion before the season opens or an off-season project with flexibility built in.

Bathroom remodeling in Sagaponack covers a wide range depending on the property. Some projects are full gut renovations everything out, down to the studs, with new plumbing rough-in, electrical, waterproofing membrane, and a complete luxury finish. Others are targeted updates: a master bath conversion to a spa-style layout, a tub-to-shower reconfiguration, or a full fixture and tile refresh that modernizes the space without touching the plumbing stack. We work across all of it.
On the finish side, the expectations here match the properties. Freestanding sculptural tubs, frameless glass enclosures, floor-to-ceiling tile, radiant floor heating, natural stone surfaces, and smart technology integration app-controlled lighting, temperature-regulated showers, voice-activated fixtures are standard requests in this market, and we execute them. High-end bathroom renovations in the Hamptons typically start around $75,000 for a master bath and scale from there depending on scope and materials. We’re transparent about that from the first conversation.
What’s built into every project regardless of scope is coastal-grade moisture management: cement board substrates, waterproof membranes, properly sealed penetrations, and ventilation systems rated for high-humidity oceanfront environments. In a village sitting directly on the Atlantic, that’s not an upgrade it’s the baseline. And if your property in Sagaponack has seen storm flooding since Sandy, we assess for latent moisture and mold before the build phase begins, so the renovation actually lasts.
Yes and this is where a lot of contractors make a costly mistake. Sagaponack is an incorporated village with its own Building Inspector and municipal code, which operates independently from the Town of Southampton’s building department. If your bathroom renovation involves any plumbing relocation, electrical modifications, or structural changes, you need a permit issued by the Village of Sagaponack not the Town.
We handle the permit process from start to finish. That includes the application, the required documentation, and coordinating all inspections through the Village. For properties in Sagaponack’s coastal zone, there may also be Coastal Erosion Hazard Area or Flood Damage Prevention requirements under the Village Code that affect how the work is permitted and executed. We know those regulations and build compliance into the project from day one so you’re not dealing with stop-work orders or failed inspections after the fact.
In Sagaponack, a high-end master bathroom renovation typically starts around $75,000 and can reach $150,000 to $200,000 or more depending on the scope, materials, and what’s discovered during demo. A targeted update new fixtures, tile, and vanity without touching the plumbing layout will come in lower, but in a village where the median home value exceeds $5 million, the finish level the property demands usually sets the floor, not the ceiling.
The honest answer is that the final number depends on what’s behind your walls as much as what’s going on them. Older construction in Sagaponack farmhouses on Parsonage Lane, traditional homes on Hedges Lane can carry pre-1980 materials that add abatement costs to the project. Coastal properties may have moisture or mold behind tile that wasn’t visible until demo. We account for these possibilities upfront in our scoping process so the estimate you get is as accurate as it can be before we start, not a number that climbs every week.
It affects almost every material decision. Salt air is corrosive it degrades standard grout, caulk, metal fixtures, and even tile adhesive faster than most homeowners expect. In a property along Daniels Lane or anywhere near Sagg Main Beach in Sagaponack, a bathroom built with inland-standard materials will start showing wear within a few years: grout darkening, caulk cracking, fixtures pitting. The ocean humidity also creates ideal conditions for mold growth behind walls if the substrate and waterproofing aren’t spec’d correctly for the environment.
The fix isn’t complicated, but it requires intentional material selection from the start. That means cement board substrates instead of drywall, waterproof membranes behind all wet surfaces, marine-grade or corrosion-resistant fixtures, and ventilation systems with enough CFM capacity to manage the moisture load a coastal bathroom generates. We build every Sagaponack bathroom to these standards because the alternative a renovation that starts failing in three years isn’t a result either of us wants.
For most contractors, it means the job stops. They’re not licensed to handle hazardous materials, so they have to bring in a specialty abatement crew which means scheduling delays, a separate contract, and a project that can sit idle for weeks while you wait. In Sagaponack, where older farmhouses and pre-1980 construction are common, this is a real risk on any gut renovation, not a remote one.
We hold active asbestos abatement and lead abatement licenses. When demo uncovers hazardous materials asbestos floor tile under the existing floor, lead paint behind the walls we handle the abatement in-house under the same contract and keep the project moving. The remediation is done to New York State standards, documented properly, and disposed of through licensed channels. You don’t get a project pause, a second contractor, or a second invoice. The work continues, and the timeline stays intact.
That’s one of the most common requests we get from Sagaponack homeowners, and the answer is yes provided we start the planning process early enough. The Hamptons renovation calendar runs on a hard deadline. Off-season work needs to be done before the season opens, and that window runs roughly from October through late April. If you’re commissioning a full master bath renovation, starting the conversation in the fall gives us the lead time to scope the project, pull permits through the Village of Sagaponack, order materials, and execute the build without compressing the schedule at the end.
We build the timeline backward from your target completion date. If Memorial Day is the deadline, that date drives every phase of the project permitting, demo, rough-in, tile, fixtures, and final inspection. We’ve executed this kind of deadline-driven project throughout the East End, and we understand what it costs in money and stress when a contractor misses the opening of the season. We don’t.
It’s more common than most homeowners realize. Sagaponack’s ocean shoreline took documented damage during Hurricane Sandy in October 2012, and properties along the oceanfront and in low-lying areas can carry latent moisture damage behind tile, inside wall cavities, under subfloors that was never properly remediated after the storm. A cosmetic repair that covered the visible damage doesn’t mean the structural damage underneath was addressed.
Before we build anything, we assess for it. If moisture mapping or demo reveals storm-related damage wet framing, compromised substrate, active or dormant mold growth we handle the remediation as a licensed mold remediation contractor before the renovation proceeds. That means the bathroom we build isn’t going on top of a problem that’s going to resurface in two years. If the damage is tied to an insured loss, we also have experience working directly with insurance carriers documenting the scope, communicating with adjusters, and billing the claim appropriately so that process doesn’t fall entirely on you.
