Well, I generally am not worried what people do, but if it is dangerous, I think we should be worried. Yes, the guy could get injured, BUT there are other things that could happen if he does. I realize that any one of us can get injured on the job with a blink of an eye. That is obvious. I think most homeowners will think everything looks dangerous and don't really know how to differentiate between the two. If this guy is doing this job this dangerously, then he probably doesn't have the proper insurance either. That H/O isn't protected if he is hurt. It costs all of us more money on our insurance if he gets hurt too. They will see incidents in the region go up (even though he won't get a payout with no insurance). I am surprised that you don't care enough about your profession to not want others to do the job correctly. People start to generalize trades if they have bad experiences. It makes it tougher for everyone when somebody screws it up for the rest of us. Just my opinion.
