Brookhaven is not a neighborhood so much as a very large town, and its housing reflects that. Across ZIP 11719 and the surrounding blocks you find post-war ranches with one-story layouts, colonials with a center hall and four bedrooms, and homes sitting on lots big enough for a driveway turnaround, a shed and a garden. Kitchens and baths in those houses tend to follow the era they were built: a closed-off galley kitchen, a single full bath serving three bedrooms, a primary suite that is really just a bedroom with a closet.
That is the opportunity. Unlike a Manhattan co-op, a Brookhaven house usually gives you room to rethink the plan. You can take a wall down, push a footprint out, move a laundry closet, or turn a spare bedroom into a proper primary bath. It also means the project is bigger than a swap of cabinets and tile, and the decisions that matter most are about layout, structure, plumbing and the order of work.
This guide is written for owners weighing a kitchen or bathroom remodel in Brookhaven, Suffolk County. It covers what the house type tends to allow, how permits and licensing work on Long Island, how the job is sequenced, and what 2026 planning ranges look like. Brookhaven sits at the far edge of our service area, so we are candid about how larger projects here are scheduled.
A one-story ranch has a footprint that is easy to read. Plumbing usually runs through a slab or a short crawlspace, the roof is framed over the whole house, and there is no neighbor's bathroom above you. That combination makes certain upgrades far more practical than they would be in an apartment.
The most common request on a ranch is to join the kitchen to the dining or living area. Whether that is a simple job or a structural one depends on what the wall carries. In many post-war ranches the wall between kitchen and dining room is a partition. In others it supports ceiling joists or a roof beam. Do not assume. A licensed pro opens a small inspection hole, traces the framing and tells you whether a header beam is needed.
Colonials often have a bedroom closet and an old hall bath that could be combined into a real primary suite. With room to work, you can plan a walk-in shower, a double vanity, a separate toilet area and a linen closet, rather than squeezing a modern bathroom into a 5-by-8 box. Our guide on bathroom renovation budgeting helps you test the scope against a number before you commit.
Because the lots are generous, many owners fold a mudroom, pantry or first-floor laundry into the kitchen project. These areas share plumbing, electrical and flooring decisions with the kitchen, so planning them together is cheaper than treating them as separate jobs a year apart.
A kitchen remodel starts on paper. Before anyone orders cabinets, you need a measured plan, appliance specifications and a decision about whether the layout changes.
Moving the sink, range or refrigerator changes plumbing, gas, venting and electrical, which drives both cost and permits. Keeping the same footprint and upgrading cabinets, counters and tile can come in well under a full relocation. Neither is wrong. The point is to choose on purpose.
A range hood that vents to the exterior needs a clear duct path, which is easy through a ranch roof or sidewall and harder in a two-story colonial where the kitchen sits under a bedroom. If you are moving to a gas range, the gas line routing and any local requirements should be settled before demolition, not after.
Brookhaven homes often have tile or vinyl over a slab, or hardwood over a wood subfloor. Each needs a different prep. Tile on a wood-framed floor needs a stiff, flat substrate and often an underlayment or decoupling membrane. If you want tile in the kitchen, review our overview of tile installation in NYC and the surrounding region for how substrate, thinset and grout choices affect longevity.
Custom and semi-custom cabinets can take weeks to arrive. Order only after field dimensions are confirmed and the layout is final. Demolition should follow delivery, not precede it, so you are not cooking on a hot plate longer than necessary.
Bathrooms fail in predictable ways. Water gets behind tile, grout cracks, a shower pan loses slope, and the wall behind it slowly softens. A remodel is the moment to fix the cause rather than the symptom.
A proper bathroom remodel takes the room down to studs and subfloor. That is the only way to see what is really there: old galvanized supply lines, a cast-iron drain, notched joists or water damage hidden for years. Selective demolition and haul-away typically run $8 to $30 per square foot as a planning range, depending on access and debris.
The membrane system behind tile is what keeps the room dry for decades. It adds roughly $3 to $10 per square foot and is the least visible line item on the quote. It is also the line owners should be least willing to cut.
Brookhaven owners increasingly convert an unused tub to a larger shower, especially in the primary bath. If you are planning for comfort as you age or simply prefer a walk-in, a curbless shower design is worth understanding early because it affects floor framing and drain placement.
A proper exhaust fan ducted to the exterior protects your finishes. Specify it in the plan, not as an afterthought.
A kitchen or bath remodel is where the cost of a mistake is highest. A shower that leaks does not announce itself for months. By the time a stain appears on a ceiling or the floor feels soft, water has been working for a long time, and the repair often costs more than the original job.
That is why a licensed, insured contractor with an in-house design-and-build team matters on a house this size. One accountable company coordinates demolition, framing, plumbing, electrical, waterproofing, tile and finish work, so no trade is left guessing what the previous one did. The sequence is controlled, inspections are scheduled around real progress, and nothing gets covered before it has been checked.
DIY and handyman shortcuts tend to fail in the same places. Waterproofing gets skipped or applied unevenly. Tile goes onto a floor that is not flat, and the lippage shows up under every light. Electrical or gas work is done without a permit, and it surfaces later when you sell or file an insurance claim. For a closer look at the trade-offs, see our tile installation guide for what proper prep, waterproofing and setting involve before you consider doing it yourself.
With N.Y. Renovation Services you get one team from plan to final coat of paint (see our Long Island coverage), a detailed written contract with transparent pricing and no hidden fees, and help with permitting and paperwork. We also donate 5% of total project cost to a nonprofit of your choice.
On Long Island, building permits are issued by the town, village or city where the property sits. For Brookhaven properties, that means the Town of Brookhaven building department, which reviews plans and inspects work. Requirements vary by scope, so confirm the specifics with the town before you commit to a layout.
Cosmetic updates, such as repainting, replacing a vanity in the same location or swapping a faucet, often do not require a permit. When in doubt, ask. Our general explainer, do I need a permit, lays out how to think through the question, though it focuses on New York City and Long Island rules differ.
Nassau and Suffolk counties require home improvement contractor licensing through county consumer affairs. Suffolk County is the place to verify what applies to a contractor working on a Brookhaven home. Ask any contractor for license details and proof of insurance, and keep copies.
Many Brookhaven homes were built before 1978. The EPA's Renovation, Repair and Painting rule requires paid contractors disturbing paint in those homes to be certified and to use lead-safe work practices. Ask for this up front, especially if young children or a pregnant family member live in the house.
Tile and stone cutting produce respirable silica dust. OSHA's silica standard calls for wet cutting, vacuum dust control and respirators where needed. A professional crew builds this into the job; a weekend DIYer rarely does.
The calendar of a remodel is mostly waiting for things that have to happen in order. Approvals, deliveries and cure times matter as much as hands-on work days.
| Phase | Bathroom | Kitchen |
|---|---|---|
| Design, measuring, selections | 1-3 weeks | 2-4 weeks |
| Permit review, if required | Weeks, scope dependent | Weeks, scope dependent |
| Demolition and rough-in | 3-5 days | 1-2 weeks |
| Waterproofing and cure | 2-4 days plus cure | Not applicable |
| Tile and finishes | 1-2 weeks | 2-4 weeks |
| Fixtures, punch list | 2-4 days | 1 week |
| Typical on-site total | 3-6 weeks | 6-12 weeks |
These are typical figures after approvals and materials are ready. Cabinet lead times, special-order tile and conditions found behind old walls can extend the schedule. The usual order of work is straightforward: demolish, rough-in, inspect, close, tile, set, paint, and only then install fixtures.
The figures below are typical 2026 planning ranges for the New York metro area as of October 2026. They are not quotes. Building rules, access, hazardous materials, finishes and scope move prices, and a written, itemized quote governs.
| Item | Typical planning range |
|---|---|
| Full bathroom renovation | $30,000-$60,000+ |
| Full kitchen renovation | $25,000-$85,000+ |
| Selective demolition and haul-away | $8-$30 per sq ft |
| Tile removal | $4-$12 per sq ft |
| Installed floor tile | $20-$45 per sq ft |
| Shower and bath wall tile | $30-$80 per sq ft |
| Backsplash tile | $30-$90 per sq ft |
| Waterproofing membrane system | $3-$10 per sq ft |
The widest swings come from cabinetry, stone countertops, relocated plumbing and the choice between standard porcelain and natural stone. For a broader look at how scope shapes the final figure, see our guide to what a renovation costs in 2026.
Brookhaven sits well beyond the core of our coverage. We are straightforward about it. Larger kitchen and bath projects here are taken by arrangement. That means we plan the crew, deliveries and site visits around your job, and we do not promise next-day availability or quick drop-in service.
For the owner, this is mostly an advantage. Projects of this size benefit from a planned start date, a single mobilization and a clear sequence. Small repairs and one-day tasks are better handled by a local tradesperson; a full remodel is a good fit for a coordinated crew.

For this page we serve Brookhaven, Suffolk County, Long Island, ZIP 11719, by arrangement for larger projects.
Local housing in this area leans toward ranches, colonials and large lots, under the jurisdiction of the Town of Brookhaven. That has practical consequences. Long driveways ease deliveries but make crew parking and dumpster placement a decision worth making early. Larger lots may mean septic systems or well water in some parts of town, so confirm what serves your house before moving plumbing fixtures. Detached garages and basements often become staging areas, which helps keep a house livable during a long project.
