Water damage restoration in Mastic Beach, NY starts with a different question than it does inland: where did the water come from? Mastic Beach sits on a peninsula that reaches into Moriches Bay, about 2.8 miles from Shirley in a straight line. If bay water, storm runoff or a failed pipe is putting water in your house, call the 24/7 dispatch line at (934) 223-1875 and say which of those it looks like.
The 2020 Census counted 14,199 residents here, a lot of kitchens and low ground floors on one peninsula, so describe your street and the kind of water when you call. Below are the first steps, the Town of Brookhaven rules, and which service fits which water.
When bay water or storm water is spreading in Mastic Beach
The first job is to work out whether the water came from outside or inside. Outside water from a storm tide or a downpour carries silt, bacteria and whatever was on the ground. Inside water from a supply line starts cleaner but still soaks into drywall fast, so once the source is dealt with, water extraction comes first.
Public reference sources list Mastic Beach at about 6.6 feet in elevation, on a peninsula reaching into Moriches Bay. That is low-lying ground. Check your own address on the FEMA flood map, and tell the dispatcher if water is coming up from the ground rather than down from the roof.
Flood water, meaning water that came in from outside the house, is where a standard homeowners policy usually stops. New York's Department of Financial Services says water backup coverage may come from an endorsement and flood coverage from a separate National Flood Insurance Program policy. Ask your insurer which you hold before a loss, because flood cleanup is treated differently from a pipe loss. Photograph everything before any cleanup starts.
Water near outlets or the panel
If water is above the outlets or around the electric panel, do not wade in to flip a breaker. Leave the house if the water is rising, and call the 24/7 line from outside.
If water is still spreading in your Mastic Beach house
Work through these in order, and stop at any step that is not safe.
Stop the source
Shut the main valve if a pipe is the cause. If the water is coming off the bay or the street you cannot stop it, so get yourself and your belongings out of its way.
Cut power to wet areas, only if safe
If the panel is dry and you can reach it without stepping in water, switch off the breakers for flooded rooms. If the floor around the panel is wet, leave it alone and tell the dispatcher.
Lift what you can
Put photos, papers and electronics on beds, counters or upper shelves.
Keep people and pets clear
Bay and flood water can carry sewage and debris. Keep children and animals out of it and wear boots if you must cross it.
Call the 24/7 line
Dial (934) 223-1875 at any hour. Give your street, the wet rooms, and what the water looks like.
Mastic Beach water problems and the service that fits
The bay and storm situations lead the list, followed by the plumbing losses any house can have.
| Situation | What usually causes it here | Service page |
|---|---|---|
| Water over the floor after a storm tide or heavy rain | Surge from the bay, runoff or rising ground water | Flood damage restoration |
| Standing water that has to come out now | Storm intrusion, a split line or a failed appliance | Water extraction |
| Toilets or drains pushing wastewater up | A flooded septic system or cesspool, or a backed-up line | Sewage backup cleanup |
| Wet lower level or crawl space | Water pushing in through walls and floor | Basement water damage cleanup |
| Leak during a nor'easter | Wind-driven rain at roof or windows | Storm water damage cleanup |
| Wet walls and insulation after the water is out | Moisture wicking up from the floor or down from a ceiling | Structural drying and dehumidification |
| Burst or leaking supply line | A line or fitting that failed | Burst pipe water damage |
Not sure which row matches? Call and describe what you see. A soaked lower level is basement cleanup work, and the crew confirms the source with moisture meters and a thermal imaging camera.
What sets Mastic Beach apart
The Forge River next door
Suffolk County's Department of Health Services places the Forge River between the hamlets of Mastic and Moriches. Homes close to it should check the FEMA flood map.
A hamlet, not a village
Voters approved a village here in 2010 and dissolved it in a November 2016 vote. Permits now go through the Town of Brookhaven, so the Town's Building Division is who to ask before you rebuild.
The William Floyd Estate
The National Park Service lists the William Floyd Estate in Mastic Beach, and its Old Mastic House is open for tours from May to September. Give the dispatcher a street address and cross street, not just a landmark.
A sewer district in planning
The Town has been planning a Mastic Beach Sewer District. Until you know whether your lot is connected or on a private system, treat any backup as sewage and ask the Town which parcels are in the district.
Dispatch around the clock
Emergency dispatch is available 24/7, including nights, weekends and holidays, at (934) 223-1875. It is call-only, with no form to fill out.
Owners, rebuilding and Town of Brookhaven rules
Census QuickFacts puts owner-occupancy in Mastic Beach at 81.6 percent, so most households here make the repair decisions themselves. If you own, keep photos, moisture readings and the written scope the crew prepares, because an insurer may ask for them. If you rent, tell your landlord right away.
Town of Brookhaven Code Chapter 33 defines substantial damage as repair costs that equal or exceed 50 percent of the structure's market value before the damage, and building in a special flood hazard area needs a permit. The county hazard plan adds a two-foot margin above base flood elevation there. Ask the Town of Brookhaven Building Division what applies to your lot before you rebuild.
The county hazard plan says about 2,400 structures in the Town of Brookhaven were damaged by Superstorm Sandy in 2012, and that the flooded properties very closely followed the areas on the FEMA flood maps. Check your address on those maps before you settle on coverage.
Frequently Asked Questions
Mastic Beach uses one ZIP, 11951, which takes in the peninsula along Moriches Bay and the streets around the William Floyd Estate. The neighboring areas are Shirley at 11967 and Mastic at 11950, and both sit close by. If you are unsure which ZIP your address falls under, give the dispatcher your street and the nearest cross street.
Yes. The dispatch line at (934) 223-1875 runs 24/7, including nights, weekends and holidays. Tell the dispatcher what is wet and whether the source is stopped. Timing depends on conditions, so ask when you call.
Both are contaminated, but a backup through a toilet or floor drain is handled as sewage. New York State has said thousands of homes in the Forge River and Carlls River watersheds relied on septic tanks and cesspools, and that Sandy flooded roughly half the area's wastewater systems. If you have either, flooding can push wastewater back into the house, which is a sewage backup job.
The crew removes standing water, then runs air movers and LGR dehumidifiers while moisture meters track the walls. Ask any company whether its crews work to the ANSI/IICRC S500 standard, and read up on structural drying first.
No. The 24/7 line also sends crews to Yaphank, Patchogue, the neighboring hamlet of Moriches and the rest of the service area around Shirley.
