FAQ
How much does pool opening cost in the Hamptons?
About $425 and up. One Hamptons service company that works East Hampton, Southampton, Water Mill, Bridgehampton and Sagaponack publishes openings and closings "starting at $425" for 2026, which buys cover removal, deck equipment reinstalled, filtration start-up, an interior clean, the fill, start-up chemicals and an equipment check. National ranges run $250–500 for an in-ground opening, with gunite pools at the top ($300–500) because there is more surface to clean and a DE filter reinstall ($300–450) costing more than a cartridge or sand one ($250–350). Closings nationally are $175–500 depending on the source. A large gunite pool with a spa, automation and a salt system will run above the starting price; a DIY opening is $50–150 in chemicals and supplies plus a Saturday.

What you are paying for
An opening is two to four hours of a two-person crew doing things in the right order: cover off, cleaned and stored; plugs out of the returns and skimmers; ladders, rails and the diving board back on; pump, filter, heater and salt cell reconnected and started; the pool brushed and vacuumed; the water topped up, tested and dosed; the equipment run and checked. What separates a $425 opening from a $250 one is mostly the pool: a 20×40 gunite with a spa, a DE filter, a heater and a salt cell is a longer morning than a 16×32 vinyl pool with a cartridge filter.

What pushes a Hamptons opening up
- The pool. Size, a spa, a salt system, a heater, automation: each is another thing to reconnect and test.
- The state it was closed in. A pool closed warm and green in October is a pool that opens green in April and needs a week of chemicals and a second visit.
- Timing. The last two weeks of April and the first of May are the crush; a seasonal-program customer gets first pick of dates. Booking a one-off opening for the Friday before Memorial Day is how you end up opening yourself.
- What the crew finds. A seized pump, a cracked filter tank, a heater that will not light after a winter in salt air: these are repairs, not opening, and they are the usual reason the invoice grows.
Opening as part of a season
Companies that work the Hamptons sell the opening inside a seasonal package for a reason. One local program is $3,350 for 20 weeks of weekly service with all chemicals included, about $168 a week, with the opening date chosen ahead of the à la carte customers. If you are going to have the pool serviced weekly anyway, the opening is effectively the first visit.
When, not just how much
Open when daytime air is consistently above 70°F, or overnight lows hold at 60–65°F, even though the water is far too cold to swim; algae is active at that temperature and a covered, warming, unfiltered pool is where it grows. On Long Island that is mid-March to early May depending on the year. The cost of opening late is not the opening; it is the green pool.
