JB Anderson Home Remodelling

The things I found attractive about signing on with JB in the first place were his seemingly fair prices, his availability to get started on my project , and his proclaimed ability to perform all the various tasks without me needing to bring in other contractors. All of this was also built on the theory that he ran a company that had a crew available, not just one man, one day at a time.
The things I have come to realize about JB and why I don't think anyone should hire him for any job (and I hate to say it) is that he is not punctual, he is not careful (several costs were incurred because of lack of care on his part breaking other things), he thinks he pays attention to detail but I tend to disagree (at least from the standpoint that he may have some vision loss), he thinks he is "working his butt off" while I am wondering how come nothing is getting done (being there for hours doesn't equate to working for hours), he doesn't project a positive image (he has no paper stock such as letterhead or even generic invoices, he drives a super dumpy, broken down van that is loaded with almost every tool he owns, and he seems to feel that supplies and even some tools are to be provided by the customer) and he is, in my opinion, not professional enough. I found it to be awkward, discomfitting and eventually rather annoying that he would expect me to provide lunches and beverages (if I want to that's fine but do not EXPECT them, please) and would ask for gas money outright, else he wouldn't be able to get to the job site. He has no checking account of his own, or credit cards, so every incidental thing that had to be purchased waited on my ability to leave work, run to the store, run to the bank and drop off materials, obviously causing delays in getting things done as well.
The cost to UNdo and REdo the plumbing that JB thought he finished was $800. The cost for the electrical REdo was $3200. The associated costs incurred for delays and impact to other contractors is at $1500 and counting. There is NO WAY I am going to have JB paint the exterior of the house, despite his having agreed to do so 10 weeks ago when we started the project.  Even IF painting is the one thing that he does really well, I anticipate it taking another few weeks to complete the task (assuming he finishes installing the siding this week yet) and I do not have the luxury of time any more. When he assured me on July 6th that we could get the house renovated in 6-8 weeks, I believed him. It has been 10 weeks so far, at least two to go, and I have exceeded the budget by almost $10K. I am not happy.
He is a great human being, friendly, outgoing, devout, respectful, eager to please, and someone you would enjoy meeting. He just needs to realize his own limitations and be more accurate about his capabilities.
