How to Start Your Own Plumbing Business: Licences, Costs, Insurance and Getting Customers

To start your own plumbing business: get the plumbing licence your state requires to run a company (often a master plumber or plumbing contractor licence), register the business, get liability insurance, bonding and workers' comp, buy tools and a service van, choose service/repair, remodel or new construction, set flat-rate pricing, use scheduling and invoicing software, and generate leads with Google, reviews and a fast website.

Steps

1. Licensing: journeyman experience, then master or contractor licence as required by your state; local business licence and permits
2. Business plan: services (drains, water heaters, leaks, repiping, remodels, commercial), service area, pricing
3. Register: LLC or corporation, EIN, business bank account
4. Insurance and bonding: general liability, commercial auto, workers' comp, contractor bond
5. Tools and van: pipe tools, drain machines, camera, press tools, water heater dolly, stocked shelving
6. Supplier accounts for parts and fixtures
7. Pricing: flat-rate price book, trip/diagnostic fees, tiered options for larger jobs
8. Software: booking, dispatch, invoicing, payments, reminders
9. Marketing: Google Business Profile, Local Services Ads, reviews, SEO pages per service (see How to get plumbing leads)
10. Hire: add plumbers and an office coordinator as call volume grows

Startup costs

Main costs: tools, van, insurance, licensing, initial inventory, software and marketing. Service and repair plumbing needs less capital than new construction.

How much plumbing business owners make

It depends on the number of trucks, pricing, average ticket and overhead; owner-operators earn their labour plus profit, while multi-truck owners earn from the team (see How much do plumbing business owners make?).
