A pool renovation in Water Mill is a five-figure job that has to happen in the right order, in the off-season, on a lot where the water table and the village rules have opinions. We put Water Mill pool owners in touch with one licensed, insured pool company that does renovations rather than only service, and we publish the 2026 ranges so the quote reads plainly.
Renovation in Water Mill: what's different here
Estates around Mecox Bay and Flying Point on wet, flat ground, older farmhouses along Montauk Highway and Halsey Lane, and wooded 1990s–2010s neighborhoods north of the highway toward Deerfield Road whose first-generation gunite and vinyl pools are reaching resurfacing and liner age.
Water Mill has pools in the salt near the water and pools under trees inland, and the renovation choices split: corrosion-proof stone, hardware and heater on one side; a pebble finish that shrugs off leaf stains and a cover that keeps the trees out on the other. Either way, coping and tile go in before the finish, and the drain-down goes to a drywell.
The bay side of Water Mill, Mecox, Flying Point and Cobb Road, has a high water table and falls under the Town of Southampton’s 150-foot wetland setback for structures and the Town Trustees’ jurisdiction over Mecox Bay; a shell here needs hydrostatic relief and a drained pool is a floated pool. Water Mill filled in from the 1990s through the 2010s, so a large stock of pools is at the age where plaster (about 10 years) and Long Island liners (8–10 years) come due at once, along with pumps past 10 years and salt cells past 5.
Permits in Water Mill run through the Town of Southampton Building Division; the pool specialist we put you in touch with handles the filing where one is required.

FAQ
Renovation questions
Should I convert my Hamptons pool to salt?
Probably, if you own the pool for the long run and fix the corrosion details. A conversion costs $500–3,500 (about $1,000 typical: a $600–2,000 generator plus $100–500 to install; no draining if the water is balanced). Ongoing chemicals drop to under $100 a year against $175–800 for chlorine, the water is softer, and there is no chlorine to store. The recurring cost is the cell: $200–1,800 depending on which of four sources you believe, every 3–6 years, roughly $200–360 a year. The catch is corrosion: copper heat exchangers, soft limestone or natural-cleft coping, and steel hardware near the water. On the South Fork that means a cupro-nickel heater exchanger and sealed bluestone or porcelain coping, and near the ocean the salt was already in the air anyway.
Gunite, vinyl or fiberglass: which pool for a Hamptons house?
Gunite is what the South Fork builds: any shape, a spa in the same shell, a 30–50+ year structure, and a finish that needs redoing every decade or two (plaster about 10 years, pebble 20+). On Long Island a standard gunite pool runs $90,000–140,000 and a custom one $100,000–400,000+. Vinyl is the budget route at $40,000–70,000, with a liner every 8–10 years at $5,000–7,500 and a 15–20+ year structure. Fiberglass is a factory shell at $45,000–85,000, a 20–30 year shell, the fastest install and the fewest shapes, and it needs a crane, which matters on a village lot. The vinyl and fiberglass Long Island figures come from a single source; treat them as a starting point.
Read the full answer →Do I need a fence around my Hamptons pool, and an alarm?
Yes to both, with one exception. New York requires a barrier at least 48 inches high around any residential pool, with no openings over 4 inches and gates that close and latch on their own, and since December 14, 2006 every pool built or substantially modified must have an approved pool alarm; where a house wall forms part of the barrier, the doors need alarms too. The exception: a pool with an automatic safety cover does not need the alarm. Villages add rules: Southampton Village allows pools only in rear or side yards behind a 4-foot fence with gaps under 4 inches; the Town and Village of East Hampton double the setbacks for pools and pool equipment; Sag Harbor reviews any fence visible from the street in the historic district. Every pool circuit needs GFCI protection and bonded metal parts, by a licensed electrician.
