What to include in a plumbing estimate
Our plumbing estimate template covers the basics every estimate needs (your details, the customer, job site, line items, totals, validity date and signature) plus the details customers in plumbing look for:
- Fixture or equipment model and size
- Labor hours and rate, or flat-rate price
- Parts list (valves, fittings, tanks)
- Permit and inspection
- Disposal of old equipment
- Warranty on parts and labor
Sample plumbing estimate

Plumbing estimating tips
Flat-rate pricing (a set price per task) is popular with plumbers because homeowners prefer a known number. If you quote hourly, give a range of hours.
List code-required upgrades as their own lines so the customer understands why the price is higher than a big-box store installation.
Once the customer accepts, bill the job with a matching invoice from Excel Invoice Maker, or convert the estimate in one click with Estimate Pro.
