Plenty of good work is done by Journeyman, helpers, or guys that have worked for 20 years and never took the test. And, plenty of bad work is done by licensed folks. In a way, licensing has hurt the retail side of our industry. So much focus has been on whether or not the guy is licensed and not enough on the quality of work. Not that I don't support licensing.
All legitmate work in the Atlanta area is done by licensed electricians. Just because the individual electrician may not be licensed that work for a contractor doesn't matter. The journeyman or helpers that work for the licensed contractor are covered by his license and insurance. The contractor is ultimately responsible for all work done under his license.
Just how do you go about focusing on the quality of work without some form of tracking system ( which is what licenseing is about), just try to submit a complaint about poor quality work when all you have is the name John Smith and a cell number. If you hire a licensed contractor you should get his license number on all communications ( estimate & invoices). Now you have a way to focus on quality because you know who you are dealing with and you do have a way to file a complaint if you are ripped off or you receive sub-standard work.
How do you know that all this great work is being done by unlicensed electricians? They don't pull permits or get inspections so all you can do is take their word for it that they are doing code compliant work. The average homeowner is not going to know the difference.
Would you rather loan your car to a licensed driver with a long clean driving history or someone without a license that's just tells you what a great driver they are. If you hire an employee the first thing you do is check out driving history before letting him/her operate company vehicles.
A driver's license doesn't make him/her a better driver but it does allow you to check out what kind of driver they are.
