Be sure the contractor has a permanent business location and telephone number. Verify them. A contractor who operates a business out of the back of a pickup truck with a cellular telephone may be difficult to find to complete a job or fix something that has gone wrong after the last bill is paid.
~When you have narrowed your search down to two (2) or (3) possible contractors, call your local Better Business Bureau, your city or county building inspection department, the Consumer Protection Section of the Department of Justice (919-733-7741) and the appropriate licensing board (see Introduction and Licensing) to see if there have been serious complaints against any of them.
And what do you find upsetting about that?
I think it's good advice.
