We put Water Mill homeowners in touch with one licensed, insured plumber who closes and opens houses in Town of Southampton every year.
Winterization in Water Mill: what's different here
Estates on Mecox Bay and the ocean lanes in the most expensive ZIP code on the South Fork, more than 60% of them counted seasonal, on outwash ground with the water table a few feet down, and the two working mills the hamlet is named for.
Water Mill is managed estates with a shutoff schedule and cottages that nobody drains; the plumber we send you to does both on the same November route.
Water Mill is a hamlet of the Town of Southampton, permitted through the Building & Zoning Division in Hampton Bays, which publishes no plumbing page or fee line; the Town keeps mechanical equipment 10 feet from the property lines (8 feet in R-10) with screening. The hamlet had 2,506 residents at the 2020 Census and a median home price of $5,885,000 in 2024, the third most expensive ZIP code in the country, with more than 60% of its houses counted seasonal by the Town’s housing plan; the plumbing is estate plumbing, and the houses are empty at the design temperature.
Permits in Water Mill run through the Town of Southampton Building & Zoning Division in Hampton Bays; the plumber we put you in touch with handles the filing where one is required.

FAQ
Winterization questions
How do I winterize my Hamptons house?
Heat it or drain it, and tell someone. Heated: leave the thermostat at 55°F or more — the insurance industry’s “reasonable care” standard for an unoccupied house, and the fact pattern a 2024 New York court case turned on — open the cabinet doors under the sinks, insulate the exposed runs, shut and drain the outdoor lines, and put a Wi-Fi freeze alarm (from about $25) on the boiler and a smart shutoff ($579.99 for the one we could price) on the main. Drained: a plumber shuts the main, drains the supply lines, water heater, traps and outdoor lines and adds antifreeze; no Long Island company publishes the price, so ask. The pipes will see 15.7°F at Islip’s design temperature, and a burst costs $200–3,000 to fix and $1,000–4,000 in damage.

Shut the main water valve first — at the meter on the main, at the pressure tank on a well — then the water heater’s breaker or gas valve, then open a low faucet and call a plumber who answers at night. A frozen line that has not burst thaws for about $100 flat; a burst repairs for $200–3,000, about $500, with an emergency call-out of $100–300, travel of $50–300 and after-hours rates of time-and-a-half to triple; the water damage runs $1,000–4,000 more. Until the plumber comes, open the cabinet doors under the sinks so warm air reaches the pipes, keep the heat on, and do not turn the water back on to see what happens. Then find what let it freeze — the open shutoff, the uninsulated run, the set-back thermostat — before the next cold night.
