How to Quote a Plumbing Job: Flat-Rate vs Hourly Pricing for Canadian Plumbers
Flat-rate or hourly? How plumbers can price repairs, water heaters, renovations and emergencies, with line items, markup and a clear client quote.
Plumbing customers want certainty, and plumbers want to be paid for hidden problems. Choosing the right pricing model for each type of job solves both.
Flat-rate vs hourly
- Flat-rate: one price for a defined task (toilet install, faucet replacement, water heater swap). Customers like it, efficient plumbers profit from it.
- Hourly (time and materials): suits diagnostics, emergencies and unknown conditions. Needs a clear hourly rate, minimum call-out and materials markup.
- Hybrid: flat diagnostic fee, then a fixed quote for the repair.
Build a flat-rate price book
For each common job, record average time, parts, travel and disposal, then add overhead and margin. Review prices every few months as costs move: markup vs margin.
Quoting renovation plumbing
Separate rough-in, fixtures, finish plumbing, permits, drywall access and disposal. See bathroom renovation costs for market context.
Emergency work
State after-hours rates upfront and get approval before starting. Document what you found with photos.
Exclusions and unknowns
- Hidden pipe condition (galvanized, polybutylene, lead service lines)
- Access repair of walls and ceilings
- Code upgrades required when opening walls
Add a clause for discovered conditions and handle extras through change orders.
Present options
For water heaters, give standard, high-efficiency and tankless options with clear differences in price and operating cost.
Speed and professionalism
Plumbers using quoting software for plumbers can present itemized options on a tablet at the door and get acceptance on the spot. For more leads, see how to get more plumbing jobs.
