A Har-Tru court in Water Mill is the surface the clubs play on, built at home, and it comes with a weekly routine and a water bill. We put Water Mill homeowners in touch with one builder who lays clay and one company that will dress it every spring, and we publish what both cost.
Har-Tru courts in Water Mill: what's different here
Part of the densest private-court neighbourhood on the fork, the trapezoid between Route 27, Flying Point Road and Cobb Road where 87 courts were counted in 2017, estates on Mecox Bay and the ocean lanes in the most expensive ZIP code on the South Fork, and no public court.
Water Mill has Har-Tru courts on estate lawns and behind village hedges alike; the builder we send you to sizes the irrigation for the lot’s water and the wind it gets.
The ground is the Bridgehampton silt loam of the outwash plain, saturated in its lower part in winter, with the water table near Mecox Bay and the ponds a few feet down; a court base here is a drainage design, and Southampton Village’s two-inch-storm retention rule next door is the standard a careful builder meets anyway. The hamlet had 2,506 people 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.
Permits in Water Mill run through the Town of Southampton Building & Zoning Division (Chapter 330) in Hampton Bays; the court builder we put you in touch with handles the filing where one is required.

FAQ
Har-Tru courts questions
Har-Tru or a hard court: which should I build in the Hamptons?
Har-Tru if you want the surface the fork plays on and will pay to keep it; a hard court if you want to walk out and play. A clay court costs $60,000–90,000 nationally plus about $2,000 a year, is watered overnight and at midday, brushed, rolled daily in the spring freeze-thaw and reconditioned every year with two tons of new material, and it plays in light rain; the clubs here are almost all Har-Tru: SPORTIME’s 33 courts, the East Hampton Tennis Club’s 15, Montauk Downs’ 6, Mashashimuet’s 8. A post-tensioned concrete or asphalt court costs $45,000–80,000, needs a wash and an algae treatment, a recoat ($4,000–10,000) when the colour wears and 30–120 minutes after rain, and lasts 10–25 years. A junior on the tournament track wants both within reach.

More than the national guides say, and they say $45,000–80,000. A new court averages $65,000 nationally, from $25,000 at the low end to $150,000 at the high, with the surface setting the range: grass $20,000–75,000, asphalt $40,000–80,000, post-tensioned concrete $45,000–80,000, Har-Tru clay $60,000–90,000, cushioned acrylic $65,000–100,000; labor alone is $30,000–35,000. Fencing adds $5,000–15,000, lighting $2,000–6,000 where a village allows it, a backboard $5,000–10,000. No Long Island builder publishes a price, and the Hamptons adds what the national guides never see: a court sunk four feet below grade for the setback rules, which stakeholders in Sagaponack put at about $100,000 extra in 2012, a base designed for a water table a few feet down, and a permit clock that ran 16–20 weeks behind in the Town of East Hampton in 2026.
