How much does pool opening cost on Long Island?

Typical residential pool openings on Long Island run roughly $300–$600 for a standard above-ground or small in-ground, $500–$900 for an average in-ground (16×32 or similar), and $800+ for large gunite or Hamptons estate-grade pools. Prices vary by company, pool size, condition at opening, and whether chemicals are included.

What's usually included: removing the winter cover and storing it, reinstalling the pump/filter/heater, hooking up plumbing lines, vacuuming out spring debris, starting circulation, and adding opening chemicals (shock + algaecide). Not usually included: major filter repairs, liner damage, heater fault diagnosis, or extensive acid washing.

Ask any company to quote opening + closing together as a pair — companies that want your weekly-service business will often bundle.
