4
Not building service agreements with property management companies — recurring commercial work provides stability
5
Neglecting the HVAC and water heater segment — water heater replacement is one of the most profitable single services

Frequently Asked Questions

Starting a plumbing business costs $15,000 to $150,000. A solo licensed plumber with a used van and basic tools can launch for $15,000-$30,000. A plumbing company with 2-3 plumbers, well-equipped vans, and more comprehensive equipment typically costs $50,000-$100,000.

Service calls typically have minimum charges of $75-$150. Most plumbing jobs are priced flat-rate by the job (water heater replacement: $600-$1,500; drain cleaning: $100-$350) rather than strictly by the hour.

Most states require a master plumber license to own and operate a plumbing business. Requirements typically include: journeyman experience (4-5 years), passing a master plumber exam, and registering with the state contractors board. Licenses cost $100-$500. Some states allow journeyman plumbers to work independently for limited scope work.

Primary sources: (1) Google searches ('plumber near me', 'emergency plumber') — Google Ads and Google Business Profile with reviews are essential, (2) Angi Leads and HomeAdvisor for new business, (3) Nextdoor for neighborhood recommendations, (4) property management companies for ongoing service, and (5) builder relationships for new construction.

A solo licensed plumber can earn $100,000-$200,000/year running their own business. A company with 3-4 employed plumbers can gross $500,000-$800,000 annually. Net margins of 20-40% after labor, vehicle costs, and overhead generate strong owner income. Emergency plumbing service (nights, weekends) commands premium rates with similar overhead.
