In California a licensed plumbing contractor can bid whatever price they want on a job. If awarded, the customer is obligated to pay per the terms of the written contract, this somehow to me leaves people open to be screwed and there are plumbers who work very unethical, I know some customers deserve it too, but when I tell someone I charge $105 an hour they tend to flip out rather than I give them some BS line with a flat price. I was wondering how is it done in other states? do you have a maximum or fair rate guidelines?
