We are Jet-Black of Long Island. We’re proud to say that we are Family Owned and Operated and that we live and work right here in Suffolk County NY. Over the many years on Long Island, we have had the honor and pleasure of working with thousands of local homeowners and business owners, as well as many charities that are near and dear to us. Jet-Black is the national leader in asphalt seal coating and repair. All Jet-Black locations are owned by a member of their respective community just like us.
