The short answer
Figuring out how to get into plumbing and turning it into a company is a two-stage climb: earn the trade credential, then build the business on top of it. Per the Bureau of Labor Statistics, most states require plumbers to be licensed, and most plumbers get there through a 4 or 5 year apprenticeship, so the path to ownership runs through the trade, not around it.
The BLS counts about 504,500 plumbing jobs in 2024, only about 8 percent self-employed, and projects 4 percent growth from 2024 to 2034 with about 44,000 openings a year: steady demand, and most plumbers never make the jump to owner.
How to get into plumbing before the business
The credential comes first: in most states you cannot legally sell plumbing work without it. Per the BLS, apprentices get about 2,000 hours of paid on-the-job training a year plus instruction in safety, local codes, and blueprint reading; finish the program and pass the exam to reach journey level. States often want 2 to 5 years of experience plus an exam, and some require master plumber status for a plumbing contractor license. The sequence for how to get into plumbing and then ownership is fixed: apprentice, journey, master where required, contractor license. Search openings at apprenticeship.gov and check your state board early.
How to start a plumbing business in 8 steps
The eight steps run in order; each one unlocks the next. License specifics vary heavily by state, so treat this as practice guidance and confirm details with your state board.
-
Earn your license first
Hold the trade license your state requires: journey level at minimum, master plumber where the contractor license demands it. Per the BLS, most plumbers get there through a 4 or 5 year apprenticeship. This is the one step you cannot skip, buy, or outsource.
-
Pick your niche
Residential service and repair is the most common entry point: small jobs, frequent calls, premium emergency rates. New-construction rough-in, commercial accounts, and drain and sewer work are the other lanes. Pick the lane where you can win work now.
-
Write a one-page plan and budget
Answer four questions: what you plumb, who buys it, what it costs to start, and what revenue makes the year worth it. Reverse-engineer that target into calls per week so you know what the goal asks of the truck.
-
Register the company
Per the SBA, a sole proprietorship is easiest to form but leaves you personally liable for business debts, while an LLC keeps your van, house, and savings separate in most instances. Talk to an accountant, then register the entity with your state.
-
Get an EIN and a business bank account
The IRS issues an EIN free at IRS.gov, so skip any site that charges for the same number. Open a dedicated business checking account the day it arrives so job money never mixes with personal money.
-
Clear licensing, bonding, and insurance
Most states require a plumbing contractor license to bid work under a company name, many boards require a surety bond, and many cities add a local business license. Start with general liability insurance and add workers’ compensation when you hire.
-
Equip the truck and set prices that hold margin
Open a supply-house account for contractor pricing, then price every job off four inputs: burdened labor, materials, overhead, and margin. The BLS median plumber wage of $30.27 per hour is a paycheck, not a price; your burdened cost runs well above it.
-
Find customers and quote fast
Referrals, past employers, and free local listings bring the first calls, because plumbing is an urgent trade where showing up first wins. Send a clear, itemized quote the same day, and track every job, receipt, and mile from day one.

Price the company into every ticket
A price that wins the job but loses money drains cash. Build every quote from cost up: burdened labor, materials at supply-house prices plus waste, overhead for the bond, insurance, and the van, then margin on top. Many residential shops run a flat-rate book so the customer sees one number and the owner is protected on long jobs. Learning how to get into plumbing as an owner means pricing all of that into every ticket, not just the hours.

How to get into plumbing and start a business: common questions
How do you get into plumbing?
Per the BLS, a high school diploma or equivalent is typically required, and most plumbers learn through a 4 or 5 year apprenticeship with about 2,000 hours of paid on-the-job training a year. Pass the licensing exam to become a journey-level plumber. Search openings at apprenticeship.gov.
Do you need a license to start a plumbing business?
In most states, yes. Per the BLS, most states and some localities require plumbers to be licensed, and some require master plumber status before issuing a plumbing contractor license. Rules vary heavily by state, so confirm everything with your state board before you bid.
Should a plumbing business be an LLC or a sole proprietorship?
Per the SBA, a sole proprietorship is the easiest structure to form, but you can be held personally liable for business debts. An LLC protects personal assets like your vehicle, house, and savings in most instances. Talk to an accountant about the fit first.
Is a plumbing business profitable?
It can be, but the profit comes from pricing. The BLS median wage for plumbers was $62,970 in May 2024, about $30.27 per hour, and that is a paycheck, not a business. Owners build profit by pricing burdened labor, materials, and overhead with a margin on top, then quoting fast.
