Only a handful of garage door companies keep a shop with a Nassau street address on Google, fewer than Suffolk has. Your choices are wider than that list, though. A request from Levittown or Long Beach goes to companies that take Nassau jobs, whichever side of the county line they work from.

Why the Nassau number matters

Every home improvement contractor holding a Nassau license has been fingerprinted, the county says, and if a licensed company leaves you with a bad job, Consumer Affairs will mediate and investigate at no charge. You have to go to that office first, before any lawsuit. Hire someone without the license and that route is closed.

Ask for the number on the phone and search it while the tech is on the way. The license guide has both county lookups and the list of what the written contract should include.
