How to Quote for Plumbing Work in the USA: Rates, Templates and Advice
US plumbers use two main pricing approaches: flat rate and time-and-materials. Here’s how each works and which to use when.
Flat Rate Pricing
Flat rate means charging a fixed price for a defined service, regardless of how long it takes. Common in residential service plumbing:
| Service | Typical flat rate |
|---|---|
| Faucet replacement (customer-supplied fixture) | $175-$325 |
| Faucet replacement (contractor-supplied fixture) | $350-$650 |
| Toilet installation | $225-$450 |
| Water heater replacement (40-gal) | $900-$1,800 |
| Garbage disposal installation | $200-$400 |
| Main drain snaking | $175-$350 |
Advantages: Customers know the exact cost upfront. Efficient plumbers make more margin on jobs they complete quickly.
Time and Materials
Appropriate for remodel plumbing, rough-in, commercial work, and complex diagnostic jobs where scope is uncertain. Structure:
- Service call fee: $75-$175 (covers dispatch and first 30 minutes)
- Hourly labor: $100-$200/hr depending on market
- Materials: At cost + 20-30% markup

FAQs
Do plumbers need a permit for every job in the USA?
Not for minor repairs (replacing a faucet, fixing a leak, clearing a drain). Permits are required for new rough-in, water heater replacements (in most jurisdictions), sewer line work, and anything involving new pipe runs. Always check your local AHJ requirements.
Should I mark up materials?
Yes – 20-30% on materials is standard and expected. You’re taking on inventory risk and handling responsibility. Never pass materials through at cost.
