tragic story..hit close to home for me after seeing a dateline program last week focused in some california home contractors and some of it was about the very issue of unlicensed unqualified contractors using other contractor licenses. how do the inspectors setting up the stings catch them? they set up a house in need of renos and invite contractors who are suspect to come by and give a quote. their easy way to find out who is potentially a suspect to invite is simply by going through the yellow pages and checking licenses where displayed against a registry and if they don't match...they admit that for all the success they have had in catching frauds, it's just the tip of the iceberg and the penalty in many cases has simply been nothing more than a fine.it's really buyer beware and scary!
