Ok so we agree they must be licensed. Now what? Are you going to call the Board and have them "Taken care of"? I might actually call and ask their opinion on this. In reality what is it that bothers you about this? The fact that they are unlicensed? The fact that you would preffer that you got to do this work? There might be a safety issue with them doing it? The only thing that would bother is if they must be licensed then they should not be doing this work untill they are licensed. That is only fair to everyone that follows the rules. As far as the work goes I say let them do it, I'd rather not. Safety? Not an issue that I can see.
