Hourly, Flat Rate, or Service Call?
Most plumbers run all three. Knowing how to price plumbing jobs comes down to whether you can see the full scope before you start.
Charge a $75 to $200 service call fee for the trip and first 30 to 60 minutes, then bill hourly after that. Many plumbers credit the fee toward the repair if the customer proceeds.
Hourly range: $70 to $130/hr self-employed, $110 to $175/hr for a licensed shop with trucks and techs.
Best for jobs you have done a hundred times: toilet, faucet, garbage disposal, water heater. The customer gets one number and no surprises, and you get paid for your speed instead of penalized for it.
Typical range: $150 to $700 for common repairs. See the table below.
Old houses, slab leaks, and anything behind a wall belong on time and materials. Quote a not-to-exceed range, document what you find, and never give a firm flat price for a job you cannot see yet.
