NYS and NYC M/WBE Certified Contractor
Most bathroom remodels look great on day one. The question is what they look like after two winters near the Peconic River after the humidity has had its way with the grout, after a pipe freezes in January and the wall gets wet behind the tile, after years of moisture pressure that older Riverside homes weren’t built to handle. That’s where the difference between a contractor who just remodels and one who understands what water does to a home becomes very clear, very fast.
When we remodel a bathroom in Riverside, the work is built around the conditions here not around what looks good in a showroom catalog. That means waterproof substrates instead of standard drywall behind your tile. It means ventilation that actually moves moisture out. It means material choices that are appropriate for a riverfront community, not just whatever’s in the supplier’s standard package. The Peconic River isn’t going anywhere, and your bathroom shouldn’t have to fight it every season.
There’s also the reality of what’s behind the walls in a lot of Riverside homes. Older housing stock, years of deferred maintenance, and documented moisture exposure from the river watershed mean that demo day sometimes turns up mold, asbestos floor tile, or lead paint. When that happens with most contractors, the job stops sometimes for weeks. We hold the hazmat credentials to handle all of it in-house, so your project keeps moving without the delay and the added cost of bringing in a separate specialist.
Green Island Group is a Suffolk County-based contractor with over 5,000 completed restoration and remodeling projects across New York State. We started in environmental remediation and disaster restoration which means we came to remodeling from the side of the industry that deals with what goes wrong, not just what looks good. That background shapes every bathroom renovation we take on.
For Riverside homeowners specifically, that experience matters. The hamlet sits at the western edge of Southampton Town, right on the Peconic River, and the homes here have faced moisture pressure, aging infrastructure, and years of limited investment. We serve the Flanders, Riverside, and Riverhead corridor with the same crew, the same standards, and the same in-house capabilities we bring to every job no subcontracting the hard parts out.
We are licensed to operate in the Town of Southampton which has its own contractor licensing requirement separate from Suffolk County and we carry EPA-compliant asbestos abatement certification, a Lead-Based Paint license, and mold remediation credentials. One contractor, fully credentialed, accountable from start to finish.
It starts with a walkthrough. Before anything gets quoted, our team looks at what you’re working with the existing plumbing layout, the condition of the walls and floor, the ventilation situation, and any visible signs of moisture damage or aging materials. In Riverside, that assessment matters more than it does in a newer community. Homes near the Peconic River have often dealt with water intrusion that isn’t obvious until demo begins, and catching it early changes the scope of the project in a way that protects you from budget surprises later.
From there, you get a written estimate with a clear scope. If permits are required and in the Town of Southampton, any bathroom remodel that involves plumbing relocation, electrical work, or structural changes does require a permit from the Southampton Town Building Department we handle the application, the scheduling, and the inspection coordination. You don’t have to figure out the difference between a Southampton Town contractor license and a Suffolk County license, or why they’re not the same thing. That’s already handled.
Demo comes next, and this is where the hazmat credentials become practical rather than theoretical. If our crew opens a wall and finds mold, or pulls up flooring that contains asbestos tile, the project doesn’t stop. It gets assessed, documented, and remediated in-house, then the renovation continues. After that, it’s rough plumbing, electrical, waterproofing, tile, fixtures, vanity, ventilation, and finish work one team, one timeline, one point of contact until the final inspection is signed off.

A bathroom remodel from Green Island Group covers the full scope demolition, plumbing rough-in, electrical, waterproofing, tile installation, fixture mounting, vanity and storage installation, ventilation upgrades, and all finish work. But what makes the service different in Riverside isn’t the list of tasks. It’s what happens when the job reveals something the previous owner didn’t know about, or didn’t disclose.
Riverside homes along the Peconic River watershed have a higher-than-average likelihood of moisture-related hidden damage. Our in-house mold remediation capability, asbestos abatement certification, and Lead-Based Paint license mean that when something turns up behind the tile or under the floor, it gets handled without stopping the clock on your project. No waiting for a separate hazmat company to clear the site. No weeks of delay while you coordinate between two contractors who’ve never worked together.
For homeowners whose bathroom remodel is connected to a water damage insurance claim a burst pipe in a January freeze, flooding from the river, storm damage that worked its way inside we have direct experience billing insurance companies and walking homeowners through the documentation process. And because the Riverside Sewer District was approved in 2024 and the planned infrastructure will eventually require plumbing updates in homes that connect to the new system, now is also a practical time to get ahead of that work. If you’re going to update the plumbing, it makes sense to do it once and do it right.
Yes, in most cases. Riverside falls under the jurisdiction of the Town of Southampton Building Department, and any bathroom remodel that involves moving or adding plumbing, modifying electrical circuits, or making structural changes requires a building permit. Cosmetic updates replacing a vanity, repainting, swapping out a toilet generally don’t require a permit. But if you’re relocating a drain, adding a shower where there wasn’t one, or opening walls to get at the plumbing, you need to pull a permit before work begins.
One thing that catches a lot of homeowners in Riverside off guard: Southampton Town has its own contractor licensing requirement that is separate from and in addition to a Suffolk County Home Improvement Contractor license. A contractor who holds only a Suffolk County license is not legally authorized to perform home improvement work in Southampton Town. Before you hire anyone for a bathroom remodel in Riverside, ask specifically for their Southampton Town contractor license not just their county or state credentials.
A midrange bathroom remodel new tile, updated fixtures, a walk-in shower or tub-shower combination, improved ventilation, and a new vanity typically runs between $15,000 and $30,000 on Long Island. National averages tend to fall around $26,000 for a midrange remodel, but Long Island labor costs, permitting fees, and material pricing generally run 30 to 50 percent above those national figures.
For Riverside specifically, there’s an additional consideration: older homes near the Peconic River have a higher likelihood of uncovering hidden issues during demo mold, asbestos floor tile, deteriorated plumbing that add to the scope. A contractor who can handle those discoveries in-house will cost less in the long run than one who has to stop work and bring in a separate specialist. The estimate you receive should be itemized and written, with a clear explanation of what’s included and what could change the scope if something unexpected is found.
It depends entirely on the contractor you hired. Most remodeling companies are not licensed for mold remediation which means if they open a wall and find active mold growth, they are legally required to stop work and bring in a licensed remediation specialist before the renovation can continue. In practice, that can mean weeks of delay and thousands of dollars in coordination costs that weren’t in your original budget.
In Riverside, this scenario is more common than in newer communities. Homes near the Peconic River have faced elevated humidity and moisture pressure for decades, and bathrooms that haven’t been updated in years are exactly where mold tends to establish itself behind tile, in wall cavities adjacent to plumbing, and under flooring that’s absorbed water over time. We hold active mold remediation credentials, which means if mold is discovered during demo, our team assesses it, remediates it, and documents the work in-house. The project doesn’t stop. It gets handled and moves forward.
For a standard full bathroom remodel demo through finish work you’re generally looking at two to four weeks of active construction time, assuming no major surprises behind the walls. The permit process in Southampton Town adds time before construction begins: applications need to be submitted in advance, and the licensing board meets on a set schedule, so planning ahead matters.
Where timelines get extended is when unexpected conditions are discovered during demo and the contractor isn’t equipped to handle them in-house. A mold discovery that requires a separate remediation company, or an asbestos floor tile situation that needs a licensed abatement contractor, can add two to four weeks to a project that should have been straightforward. In Riverside, where older housing stock and Peconic River moisture exposure make those discoveries more likely, choosing a contractor who can handle the full scope without stopping is one of the most practical ways to protect your timeline.
The timing is actually better than it’s been in a long time. Riverside is in the early stages of its most significant planned transformation in decades the 2024 approval of the Riverside Sewer District, the $35 million wastewater treatment plant planned for Flanders Road, and the anticipated development of over 2,300 units of new housing and 3.2 million square feet of mixed-use space are not distant possibilities. They’re funded, approved, and moving forward. As that investment takes hold, property values in the hamlet are positioned to respond.
A midrange bathroom remodel returns approximately 80 cents on the dollar at resale nationally. In a community where values are on an upward trajectory for the first time in years, that return may be more favorable. Beyond resale value, the planned sewer infrastructure will eventually require plumbing updates in homes that connect to the new system making now a practical time to modernize your bathroom’s plumbing while the work is already open, rather than doing it twice.
Yes, and this is one of the more common ways bathroom renovations get started in Riverside. A pipe that freezes and bursts during a January cold snap, water intrusion from a Peconic River flood event, or storm damage that works its way into the bathroom walls these are real, recurring scenarios in this community, and they often trigger insurance claims before they trigger renovation plans.
We have direct experience navigating that process. We can bill insurance companies directly, help document the damage in the format insurers require, and guide you through the transition from covered restoration work to the renovation scope that brings the bathroom up to where you actually want it. For homeowners who’ve never filed a property damage claim before, having a contractor who’s done this hundreds of times is a meaningful advantage it takes a complicated administrative process off your plate at a moment when you’re already dealing with enough.
