Why water gets into East Patchogue homes
The flood-prone part of East Patchogue is the stretch south of Sunrise Highway, which is also where the unsewered properties are concentrated. In East Patchogue, flooding is the outside risk, and inside the house the risks are a cesspool backing up, water getting into the basement and old plumbing leaking inside the walls.
- Water coming in from outside. Flood insurance covers only basics below ground level, such as the furnace, the water heater, the electrical panel and unfinished walls, not finished floors or belongings stored there. About 7.7% of East Patchogue's built-up land is in FEMA's flood zone, where a home has at least a 1-in-100 chance of flooding in any year. Since 1978, policyholders in ZIP 11772 have filed 824 federal flood insurance claims, a record of flood water reaching buildings in this ZIP. Look up your street. Storm Damage Restoration help
- Sewage coming up a drain. Anything porous the sewage reaches, such as carpet or drywall, usually has to come out, and what stays has to be disinfected before it is dried. At 6,435 of the 7,238 addresses in East Patchogue, wastewater goes to a cesspool or septic tank because no sewer main is mapped past them, so a full or failing system can push sewage back into the house. Cesspool Overflow help in East Patchogue
- Water in the basement. Homeowners policies usually exclude groundwater seeping in, so photograph the damage and read your policy before the cleanup starts. Groundwater under East Patchogue averages 15 ft deep and rises within reach of a basement floor on some streets, so a wet basement there may be coming from below.

- A leak or a burst pipe. A leak caught early is a drying job; one that has run for weeks inside a wall is a mold job, so have it opened up and dried properly. About 49% of East Patchogue's homes were built before 1970, and pipes from that era, galvanized steel and cast iron, corrode from the inside until a joint or a section gives way. If a pipe bursts, shut the main water valve first; a split supply line keeps running at full pressure until someone does. Ceiling & Roof Leak Water Damage help
