Do pool contractors need a license in Nassau County?

Yes. In Nassau County, any Home Improvement Contractor — including those performing pool installation, major repair, liner replacement, or renovation work — is required to be licensed by the Nassau County Office of Consumer Affairs. Routine weekly maintenance and water-chemistry service generally falls outside HIC licensing, but any structural, electrical, or plumbing work on a pool does require an HIC license.

You can verify a Nassau County HIC license on the Office of Consumer Affairs website. Always ask for the license number before signing any contract, and confirm it's active.

Hiring an unlicensed contractor for work that requires a license can void your homeowners insurance claims if something goes wrong and leaves you with no legal recourse under Nassau's consumer protection laws.
