A plumber’s bill is made of labour (hourly or flat rate), parts, fees such as the service call, permit and disposal, and sometimes finish work. Emergency and 24/7 calls add an after-hours premium, often 1.5 to 2 times the regular rate. Repairs with easy access cost the least, and hidden leaks inside walls cost the most.

Outside business hours, expect a higher service-call fee and an after-hours rate, often 1.5 to 2 times the regular rate. If you can stop the water by closing the main valve, booking during business hours can save a lot. Our guide on emergency plumber costs explains when it is worth calling right away.
Regular repairs vs. renovations
Repairs are usually priced by the hour or as flat rates. Renovations, such as a new bathroom or a basement suite, are priced as a project and often need a permit. For renovations, ask for a detailed written quote that separates rough-in, finish plumbing, fixtures and permits.
