Seaford, NY 11783
Seaford is a Census-designated place in Nassau County on Long Island's south shore. The home base is 4034 Sunrise Hwy, and the 11783 ZIP covers the streets between Sunrise Highway and Merrick Road. Water, sewage and mold calls from every Seaford address are answered on the same 24/7 line.
Seaford addresses are served first. For a quick look at what we handle, see the full services list or start with emergency water extraction.
The streets between Sunrise Highway and Merrick Road include everything from older neighborhoods to newer infill, and each has its own plumbing and drainage. Describe your building on the call, because a finished basement, a slab-on-grade addition and a second-floor bathroom each change where the water goes.
Seaford calls are answered first, around the clock.

Dispatch also takes calls from Wantagh, Massapequa, Massapequa Park, Bellmore, Merrick, Levittown, Bethpage, East Meadow, Amityville, Farmingdale, Copiague, Roosevelt, Freeport and Uniondale. Availability depends on crews on duty, so call to confirm that your address is in range.
These towns do not have separate pages on this site. Every service page applies to them, and the water, sewer and permit authorities differ by town, so ask your own utility and building department.
If you live on a canal or near the bay side, ask your insurer about flood coverage before storm season rather than after, since standard policies exclude it.
Local authorities worth knowing
Water service for Seaford and North Seaford comes from Liberty Utilities, which lists them in its Merrick system. Sewer service for Seaford is run by the Nassau County Department of Public Works. Building permits for rebuild work go through the Town of Hempstead Department of Buildings, so check there before structural repairs.
For fire, gas or electrical danger, call 911. The Seaford Fire Department covers Seaford. Read about flood damage if the water came from outside, or sewage backup cleanup if it came from a drain.

Call (516) 845-9582How coverage works day to day
Coverage is set by crews on duty, not by a fixed map. A call from a Seaford address at 2 a.m. and a call from a neighboring town on a busy storm night are handled by the same dispatch line, but the order in which jobs are answered depends on conditions. The line tells you honestly what is possible when you call.
No arrival time is promised. For losses that are not active you can usually book the next available visit. If water is flowing, shut the source first and say so on the call.
What changes from town to town
Restoration steps are the same everywhere on the south shore, but the authorities are not. Water district, sewer district, building department and flood exposure can all differ across a few streets. Ask your own water supplier whether a boil notice applies, ask your building department about permits, and check the FEMA flood map for your exact address.
Within Seaford, Liberty Utilities, the Nassau County Department of Public Works and the Town of Hempstead Department of Buildings are the three offices worth knowing. Nearby towns may use other districts, so confirm before you assume.
Services available across the area
Every service page applies across the area. Water that rises from outside is covered on the flood damage page, wind-driven rain on the storm damage page, and businesses are handled on the commercial page. Mold work follows the mold remediation page once the moisture source is stopped.
Neighborhood pages
Two neighborhood pages describe how water problems differ across Seaford. Seaford Harbor covers the canal-side south, and Seaford Manor covers the inland north.
Frequently asked questions
Do you serve my town if it is not Seaford?
Possibly. Dispatch takes calls from Wantagh, Massapequa, Bellmore, Merrick, Levittown and other nearby south shore communities, and availability depends on crews on duty. Call and give your address.
Which ZIP code is the home base?
The home base is ZIP 11783 in Seaford. Calls from other ZIP codes are welcome and are confirmed by phone, since coverage depends on crews on duty.
Do nearby towns have their own page?
No. Every service page applies across the area, and the authorities that differ by town, such as water districts and building departments, are noted on the page where they matter.
What if I am outside the listed towns?
Call anyway. Dispatch will say whether a crew can reach you, and if not, will tell you so quickly rather than leave you waiting.
Check your address with dispatch before water makes the decision for you.
