Many of these contractors pick up illegals , the ones who can hook up electricity, hook up plumbing,and they are not certified and licensed by state to do this kind of work. They do not get building permits. Contractors take short cuts , later on the home owner starts discovering flaws and shoddy , workmanship and the home owner is out $$$$$$$$$$...and contractor is long gone
I had my original driveway put in very poorly. The replacement driveway was redone by illegals hired by the contractor.
