Christmas & Holiday Lighting in Mount Sinai

Ask anyone in Mount Sinai for directions and they'll point you to Mount Sinai Harbor or Cedar Beach. Mount Sinai is a wooded North Shore hamlet wrapped around its harbor — Cedar Beach and the harbor on the north, and 1970s–2000s family subdivisions climbing the slope to 25A. The homes run to 1970s and '80s Colonials on wooded half-acre lots near Mount Sinai Harbor, harbor-front homes on Mount Sinai Harbor, and 1990s and 2000s homes in the newer subdivisions off Route 25A, and that range is exactly why a one-size display doesn't work here.

Two things shape every Mount Sinai install. First: homes facing the water near Mount Sinai Harbor get sealed connections and wind-rated clips on that side; the street side gets the same product so the display ages evenly. Second: the harbor keeps the gusts down; it doesn't keep the salt out of an unsealed plug. Every connection is sealed against the harbor damp, and sloped-lot access is mapped before the crew arrives.

Mount Sinai Christmas & Holiday Lighting FAQ

What kind of Mount Sinai homes do you usually light?
Mostly 1970s and '80s Colonials on wooded half-acre lots near Mount Sinai Harbor or harbor-front homes on Mount Sinai Harbor, plus the 1990s and 2000s homes in the newer subdivisions off Route 25A — that's the bulk of Mount Sinai, and we've installed on all of it. We'll come out, measure, and quote it on the spot — no obligation, and the price doesn't move after we schedule.
Does the harbor-side weather in Mount Sinai affect the lights?
The harbor shelters homes from the worst of the wind, but salt air still works on connections, and hillside lots mean rooflines at several heights. We use sealed commercial-grade strands throughout and plan ladder placement for terraced and sloped lots before the crew arrives. A dark section in Mount Sinai mid-season is our problem, not yours; the service call is included.
Is it too late to get lights up in Mount Sinai this year?
Usually not — the Commack calendar is tight around Thanksgiving but we install straight through December. Earlier is better for choice of dates; a call now gets you the next open slot for Mount Sinai, and takedown is included in January.
Do you light businesses in Mount Sinai too?
Yes — storefronts and offices along Route 25A, Mount Sinai–Coram Road, and Shore Road and the blocks around Mount Sinai Harbor. Commercial installs are scheduled around your hours, with power and load confirmed before the first strand goes up.
How is a Mount Sinai install different from one a few towns over?
Mount Sinai is a wooded North Shore hamlet wrapped around its harbor — Cedar Beach and the harbor on the north, and 1970s–2000s family subdivisions climbing the slope to 25A. In practice that means newer Colonials with two-story entries get the entry column outlined.
Who do I call for Mount Sinai?
631-430-5782 — that's the Commack office, which covers Mount Sinai along with Port Jefferson, Miller Place, and Port Jefferson Station. You're talking to the team that will actually be on your roof, not a call center.
