On average, hourly plumber costs range between $45 and $200, but this can jump 1.5 to 3 times more to cover the cost of emergency plumbers. A plumber's hourly rate will cover labor and typically varies based on the time, expertise, and materials needed for the project. Charging by the hour is the industry standard, but some plumbers may charge flat fees for routine fixes like clogged drains or low water pressure.
