Worked example: a water heater price
Luis lists the tank, fittings, expansion tank where code requires it, venting parts, permit fee, haul-away, labor hours and overhead share, then adds his margin. He prices standard replacements as a package and explains what could add cost, such as code upgrades or difficult access, before the job starts.
Costs owners forget
- Drain cable replacement and machine repairs
- Camera repairs, which can be expensive
- Return trips for parts
- Warranty callbacks
- Permit fees on changeouts
- Card processing fees
Cash flow on bigger jobs
Repiping, sewer line replacement and commercial work can tie up materials and labor for days before payment. Take deposits where appropriate, bill progress on longer jobs, and keep a reserve so slow-paying commercial accounts do not squeeze payroll. Residential service calls paid on completion are steadier; balance both.
