Salt Water Pool Service on Long Island

8 companies offering salt water systems, each with a Nassau or Suffolk County license we checked on Sep 24, 2026.

About this service

Salt systems still need regular attention: cell cleaning, salt level checks and eventual cell replacement. If you are converting to salt, ask about equipment compatibility and the effect on existing surfaces and metal parts.

Questions to ask before you hire

  • Do you clean and inspect salt cells as part of service?
  • Which salt system brands do you install and repair?
  • Do you do chlorine-to-salt conversions?
