How to check an epoxy floor installer's license in Suffolk or Nassau
A license number takes a minute to check and tells you the company can legally do the work. Here is who issues it in each county, where to look it up, and what else to ask, from the official pages we read on 2026-11-03.

Towns with a license of their own
- Town of Southampton: Southampton requires its own Home Improvement Contractor's License for home improvement work, and its licensing covers every village except the Village of Westhampton Dunes. A builder of a new home needs no town license for now, but the builder's subcontractors must be licensed.
- Town of Southampton: A Southampton home improvement license is valid for one year. A new application costs $250.00 by cash or check or $257.50 by credit, and an on-time renewal costs $175.00, or $180.25 by credit.
- Town of Shelter Island: Shelter Island requires home improvements to be performed by a licensed contractor holding a Shelter Island license.
- Town of Shelter Island: Shelter Island's notice to contractors says every contractor or subcontractor working on the island, landscapers included, needs a town license.
- Town of Shelter Island: Shelter Island takes home improvement license applications online, and a new license needs a $250 check to the town, a liability certificate naming the town as certificate holder and, if applicable, a workers' compensation certificate.
Beyond the license
- Ask for a certificate of insurance sent to you by the insurer, naming you as the certificate holder.
- Ask who files the permit and books the inspections, and get it in the contract.
- Get the price, the scope, the start and finish dates and the payment schedule in a written contract.
