Licensing in Suffolk County

Suffolk County licenses home improvement contractors, including pool builders and pool service companies, through its Department of Labor, Licensing & Consumer Affairs. Nassau licenses don't carry over, so a company working in both counties should hold both. Each listing shows the Suffolk license number, status and expiry we found — including the East End and the Hamptons.
