From the Gold Coast estates of Old Westbury, Sands Point, and Locust Valley, to Garden City and Manhasset colonials, to Five Towns waterfront luxury in Hewlett Harbor and Old Lawrence ("the First Hamptons"), to Long Beach barrier-island singles, to the Massapequa–Wantagh–Bellmore suburban belt — we install Lutron, Control4, Crestron, and Savant smart home across every Nassau County community. Licensed NYS #12000287431. 25+ years of Nassau work.
Request a Free Nassau Consultation →Nassau County is the inner half of Long Island — the western 287 square miles between the Queens border and the Suffolk County line — and it contains the densest concentration of high-end suburban single-family housing in the entire Northeast. More multi-million-dollar homes per square mile than Westchester, more Gold Coast estates than the Hamptons, more LIRR commuter villages than any comparable suburban region in America. The Nassau North Shore alone preserves the surviving estates of the Vanderbilts, the Guggenheims, the Phipps, and Otto Hermann Kahn — 1,200 Gold Coast mansions were built here between the 1890s and 1930s, and the ones that survived (about a third) sit on 2-to-10-acre lots in Old Westbury, Sands Point ("East Egg" in Gatsby), Kings Point ("West Egg"), Locust Valley, Mill Neck, Matinecock, Brookville, Upper Brookville, Glen Cove, Cold Spring Harbor, and Lloyd Harbor.
Then there's the inner ring — Garden City, Manhasset, Roslyn, Great Neck, Port Washington, Mineola, Floral Park, New Hyde Park, Williston Park — where 1920s Tudors, brick colonials, and stately center-hall colonials sit on 50x150 lots and house attorneys, surgeons, finance executives, and the kind of multi-generational professional families that have lived in Nassau for three or four generations. Garden City alone is one of America's first planned suburban communities, designed in 1869 by Alexander Turney Stewart. These neighborhoods have the budget for whole-home Lutron HomeWorks QSX, multi-zone HVAC integration, motorized shades, and full Sonos distributed audio — and that's exactly what we install there week after week.
The Five Towns (Lawrence, Cedarhurst, Woodmere, Hewlett, and Inwood) sit at the southwestern corner of Nassau, forming a uniquely affluent pocket on the South Shore where Old Lawrence — historically called "the First Hamptons" — features waterfront mansions and beachside villas comparable to anything on the North Shore Gold Coast. Hewlett Bay Park, Hewlett Harbor, Hewlett Neck, and Woodsburgh contain some of the highest-priced waterfront homes in southwestern Nassau. Then there's Long Beach, Lido Beach, Atlantic Beach, and Point Lookout — the Nassau barrier island where Sandy hit hardest in 2012 and where every smart home install now needs to include flood protection. And finally the broad post-war suburban belt: Levittown, Hicksville, Bethpage, Plainview, Syosset, Jericho, Wantagh, Bellmore, Merrick, Massapequa, Seaford, and East Meadow — the bread-and-butter Nassau housing market where 1940s through 1970s single-families sit on quarter-acre lots and where right-sized Lutron Caseta packages do exactly what owners need at exactly the price point they expect.
Abstract Enterprises has been installing across all of Nassau County for 25+ years. We carry every major dealer certification — Lutron Caseta, RadioRA 3, HomeWorks QSX; Control4, Crestron Home, Savant Pro — and we install the full entry-level ecosystem of Amazon Alexa, Google Home, Apple HomeKit, Ring, Nest, Ecobee, August, Yale, Philips Hue, Eero, Ubiquiti, and Sonos. Whether you need a $3,100 Caseta starter for a Levittown ranch or a $300,000 Crestron whole-property build for a Sands Point waterfront estate, we design and install both with equal care. Nassau work dispatched out of our Brooklyn office (1282 Troy Ave) — call (347) 934-8335.
Nassau is too big and too diverse to treat as one market. Each of the six categories below has its own building stock, its own price point, and its own correct installation approach.
Nassau's North Shore from Great Neck and Kings Point east through Manhasset, Sands Point, Port Washington, Roslyn, Roslyn Estates, East Hills, Old Westbury, Brookville, Upper Brookville, Glen Cove, Glen Head, Sea Cliff, Locust Valley, Mill Neck, Matinecock, Lattingtown, Bayville, Centre Island, Cove Neck, Oyster Bay, and Oyster Bay Cove. The surviving Gold Coast estates from the 1890s–1930s era — Old Westbury Gardens (the Phipps Charles II English-style mansion on 200 acres of formal gardens), Sands Point Preserve (the Guggenheim Estate with Hempstead House at 50,000 sqft, Castle Gould, Falaise, and Mille Fleur), Coe Hall and Planting Fields Arboretum, the Vanderbilt Museum at Centerport, Caumsett State Park (the Marshall Field III estate). Modern Old Westbury mansions on 4-acre lots regularly list for $8M+. Failure mode: 6,000–25,000+ sqft houses with detached garages, pool houses, gates, guest cottages, and tennis courts. Generic installers underdesign the network and fail at scale. Solution: Lutron HomeWorks QSX whole-property, Control4 or Crestron Home overlay, Cat6A structured backbone, multi-AP Ubiquiti UniFi enterprise network, dedicated home theater, gate intercom, pool/spa control, full security integration. Typical Gold Coast scope: $80,000 to $400,000+.
The classic Nassau suburban professional belt. Garden City (designed 1869 by Alexander Turney Stewart, one of America's first planned suburban communities), Manhasset (the original "East Egg" before Sands Point took the title), Roslyn, Great Neck, Port Washington, Mineola, New Hyde Park, Floral Park, Williston Park, East Williston, Albertson, Carle Place, Westbury, Hempstead, West Hempstead, Lynbrook, Malverne, Valley Stream. 1920s Tudors, brick colonials, center-hall colonials, and post-war singles built primarily 1920s through 1960s. 50x150 to 100x200 lots. Owner-occupied multi-generational professional families. Failure mode: Owners want full smart home but the budget is real and they don't want Gold Coast prices for Garden City work. Solution: Lutron RadioRA 3 whole-house, Sonos in 3–5 rooms, multi-zone Nest, motorized shades in main living areas, full security integration, Ubiquiti UniFi mesh, Ring Pro doorbell, smart locks. Typical Garden City and inner-ring scope: $16,000 to $48,000.
The southwestern Nassau pocket — five villages and hamlets along the Far Rockaway LIRR branch in the Town of Hempstead. The "Five Towns" name dates to 1931 when local Community Chest groups banded together. Five Towns includes Lawrence, Cedarhurst, Woodmere, Hewlett (which itself contains Hewlett, Hewlett Bay Park, Hewlett Harbor, Hewlett Neck, and Woodsburgh), and Inwood. Old Lawrence or Back Lawrence — historically called "the First Hamptons" — features mansions and beachside villas comparable to anything on the Gold Coast, with some properties dating to the time of the American Revolution. The area is also home to one of the largest and most established Orthodox Jewish communities in suburban America, with Central Avenue in Cedarhurst (sometimes called "Long Island's Rodeo Drive") featuring 240+ stores, kosher restaurants, and bakeries. Failure mode: The Five Towns mixes ultra-luxury waterfront with classic suburban singles in a small geography, and installers without local familiarity end up either over-pricing routine work or underdesigning waterfront jobs. Solution: Free walkthroughs that match the right scope to each home. Ultra-luxury Lutron HomeWorks QSX for Hewlett Harbor waterfront and Old Lawrence mansions. Mid-range RadioRA 3 for typical Cedarhurst and Woodmere colonials. Renter-friendly Caseta for Inwood and Cedarhurst rentals. Typical Five Towns scope: $4,500 to $150,000+ depending on which town and which home.
Nassau's barrier island — Long Beach, Lido Beach, Point Lookout, Atlantic Beach, and the connected communities of Island Park and Bay Park. Sandy hit this part of Nassau harder than almost anywhere else in 2012, and every install now needs to include flood protection as a baseline. Single-family Cape Cods, ranches, and waterfront colonials, plus mid-rise oceanfront condos in Long Beach proper. Failure mode: Salt air destroys generic outdoor cameras, Sandy taught everyone what storm exposure means, and consumer outdoor gear fails fast in this environment. Solution: Marine-grade IP67/IP68 stainless cameras, NEMA-rated outdoor enclosures, water leak sensors, automatic shutoff valves, battery-backed alarms with cellular backup, freeze sensors, dock cameras integrated into interior keypads. Typical Long Beach barrier island scope: $14,000 to $60,000.
The classic Nassau South Shore from Freeport east through Baldwin, Oceanside, Merrick, Bellmore, North Bellmore, Wantagh, Seaford, Massapequa, and Massapequa Park. Single-family colonials, capes, splits, and ranches built 1940s through 1970s on 50x100 to 80x150 lots. The Long Island Rail Road runs the entire length and these are the classic LIRR-commuter towns where every weekday morning thousands of professionals catch trains to Penn Station. Some bayfront waterfront in southern Massapequa, Bellmore, and Merrick. Failure mode: Mixed-era electrical (1947 originals plus various 1960s–2000s rewires), commuter families with limited time for installation drama, and budgets that need to deliver real value. Solution: Hybrid Lutron RadioRA 3 + Caseta system that handles both modern and pre-war switch boxes, geofence-triggered "Returning Home" scenes for LIRR commuters, multi-zone Nest, Sonos, Ring Pro, smart locks. Typical South Shore Nassau scope: $11,000 to $35,000.
The original American suburb. Levittown was built starting in 1947 with 17,447 nearly-identical Cape Cods on quarter-acre lots — the prototype for every American suburb that followed. The broader post-war single-family belt extends through Hicksville, Bethpage, Plainview, Syosset, Jericho, East Meadow, and parts of Westbury. 1947–1965 construction, modest 1,000–2,200 sqft homes, often expanded with additions and dormers over the decades. Failure mode: Modest budgets paired with 1947-era electrical and tight floor plans. Solution: Right-sized Lutron Caseta or RadioRA 3 packages, mesh Wi-Fi upgrade, single-zone smart thermostat, smart lock, video doorbell. Real value at the price point that fits this market. Typical Levittown belt scope: $4,500 to $14,000.
Nassau runs from $400K Levittown starter capes to $25M Sands Point waterfront estates. We design both ends of that spectrum with equal care.
Wireless, retrofit-friendly, the right answer for Levittown ranches, Hicksville splits, Bethpage colonials, smaller Five Towns homes, and any Nassau starter under 2,000 sqft. Includes the 10% LI markup.
Perfect for: Levittown, Hicksville, Bethpage, Plainview, Wantagh, Bellmore, Seaford, East Meadow, Inwood, smaller Cedarhurst homes.
Hardwired, centrally controlled, integrated with security, HVAC, pools, outdoor entertaining, gated entries, and detached structures. Includes the 10% LI markup.
Perfect for: Old Westbury, Sands Point, Kings Point, Locust Valley, Matinecock, Mill Neck, Cold Spring Harbor Gold Coast estates; Garden City, Manhasset, Roslyn large colonials; Hewlett Harbor and Old Lawrence Five Towns waterfront.
Most common Nassau project size: $14,000–$42,000. That covers a Lutron RadioRA 3 whole-house lighting system in a typical Garden City colonial, Manhasset Tudor, Roslyn split, or Massapequa colonial, Sonos in 3–4 zones, motorized shades in main living areas, multi-zone Nest, smart lock, Ring Pro doorbell, and full Wi-Fi mesh upgrade. Free on-site consultation anywhere in Nassau — call (347) 934-8335 or request a quote online.
Brand selection in Nassau is driven by home size, neighborhood, and outdoor scope. A Sands Point estate needs HomeWorks QSX + Crestron + UniFi enterprise. A Wantagh ranch needs RadioRA 3 + Sonos + Nest. A Hewlett Harbor waterfront needs marine-grade everything. A Cedarhurst rental needs renter-friendly wireless. We match brand to home, never the other way around.
Nassau single-family homes are the perfect bundle environment. One trip out from Brooklyn covers everything — security, automation, audio, networking, access control. Bundling with one licensed contractor instead of three or four eliminates weeks of scheduling friction and saves real money on coordination overhead.
For Old Westbury, Garden City, Manhasset, Roslyn, and Hewlett Harbor single-family homes during renovation. Cat6A to every room, central wiring closet, RJ45 jacks at every TV and desk location. Pre-wire is 5–10× cheaper than retrofit.
Camera feeds overlay into Lutron keypads and Control4 app. Especially valuable on Gold Coast estates and Five Towns waterfront homes with detached garages, pool houses, and gated entries.
For Old Westbury, Sands Point, Kings Point, Locust Valley, Matinecock, and Hewlett Harbor gated estates. ButterflyMX, 2N, or Akuvox commercial intercoms with HD video and phone integration.
Pentair, Hayward, and Jandy pool/spa systems integrate with Control4 and Crestron. Standard expectation on the Gold Coast and any large Nassau property with pool and outdoor entertainment.
Dedicated theater rooms with projector, in-ceiling Atmos speakers, motorized blackout shades, and one-touch "Movie" scenes. Common in Gold Coast and Garden City finished basements.
For Long Beach, Lido Beach, Atlantic Beach, Point Lookout, Bay Park, Freeport Bayfront. Water leak sensors, auto shutoff valves, battery-backed alarms with cellular backup, freeze sensors. Critical post-Sandy.

The questions we field every week on Nassau consultations — from Sands Point waterfront estates to Levittown Capes to Cedarhurst kosher catering halls.
Upgrade Wi-Fi first — replace the ISP router with Eero Pro 6E or Ubiquiti for whole-house coverage. Pick one voice ecosystem (Alexa works for most). Add Lutron Caseta in main rooms. Add a smart thermostat per HVAC zone. Add a video doorbell and smart lock. Test for a month, then expand. Works in everything from Levittown to Sands Point.
Lutron HomeWorks QSX — supports 1,000+ devices, integrates with Crestron and Control4, custom-engraved keypads, full motorized shade integration, scales across multi-floor estates with detached garages, pool houses, and gated entries. The Gold Coast standard.
Yes, with renter-friendly removable scopes: Lutron Caseta, Philips Hue bulbs, battery video doorbells, smart plugs, August locks over existing deadbolts, Echo speakers. Works in Cedarhurst, Inwood, Lawrence, Woodmere, Hewlett rentals.
Yes, more meaningfully than in NYC apartments because Nassau single-families have larger HVAC loads. Smart thermostats save $300–$600/year on a typical Nassau colonial. Lutron dimming saves another 15–20% on lighting. Motorized shades on west-facing windows cut summer AC load substantially.
Abstract Enterprises is a certified Lutron installer serving every Nassau community from Great Neck to Massapequa. We install Caseta, RadioRA 3, and HomeWorks QSX weekly. Call (347) 934-8335.
Entry single-family scope: 1–2 days. Mid-range RadioRA 3 with Sonos: 4–7 working days. Gold Coast whole-house HomeWorks QSX with pool, gate, and outdoor: 4–8 weeks. Garden City Tudor whole-house: 5–10 working days. Sandy-prep flood protection adds 1–2 days.
Budget: $500–$3,500. Time: 15–35 hours over weekends. Reality: works for newer Nassau homes (post-1990 construction) where wiring is modern and you don't need anything integrated. Falls apart in Gold Coast estates, Hewlett Harbor waterfront, multi-zone HVAC homes, Long Beach Sandy-prep installs, and any property with pool, dock, or gate integration.
Budget: $5,000–$400,000+. Time: 1 day to 8+ weeks. Result: properly designed network, full documentation, warranty, and a system that scales as you upgrade.
Our honest Nassau take: If your home is small, modern, and you want a few isolated devices, DIY works. If your home is large, pre-war, on the water, in a historic neighborhood, or you want anything integrated across rooms, hire a pro. Free on-site consultation anywhere in Nassau.
