My plan was to have an old kitchen faucet head replaced with a new one I had bought, a 5 minute job at most. The plumber told me it would first be a $28 assessment fee and then a "job " cost but they could not quote phone costs or give me any indication of a range cost. I declined to use them and to find a handyman instead. Plumbers stories significantly overcharging seem prevalent and I could see it could well happen to me. I got a handyman who did the job in 3 minutes flat! The Plumbing Costs Chart you sent out is good, it shows it would probably have cost me $200 for 5 minutes plus $28 assessment fee.
Another way to avoid a service call from your plumber is to make sure the outside faucets are turned off in the winter and make sure you disconnect the outside hoses. You need to shut the water off from the inside. Then, open the valve on the outside to let the water that’s in there drain out—you switch both of them to the opposite direction so one is always closed and one is always open. We have to fix tons of these in the spring mostly because people leave their outside hoses connected and they freeze up. The repair could cost $100-$200 or more. Another tip would be if you’re going away for any length of time, like on vacation, turn off your water. If on any of those days the temperature drops below freezing, have someone check in on your house. I’ve been called to homes where the family returned from vacation, and there was water flooding out from the front door.
