Why This Business

Every other business on this list, a determined person can start in a week. Plumbing is different — and that’s exactly why it’s worth doing.

The license barrier eliminates 95% of potential competitors. By the time you’re a licensed plumber with your own business, you’re in a protected market where customers actively seek you out, can’t easily price-compare on Craigslist, and will pay $75-150/hour without flinching because the alternative is a flooded kitchen.

Here’s the real appeal: licensed plumbers are in short supply. The average plumber is 58 years old. There aren’t enough young people entering the trade to replace the ones retiring. In many cities, service calls book 2-3 weeks out. You will have more work than you can handle within 6 months of getting your license and starting your business.

If you’re already licensed and working for someone else, this guide is your exit plan. If you’re considering the trade, the 4-5 year apprenticeship is the most valuable trade school you can attend — and you get paid while doing it.

What You Need to Start

License: Most states require a journeyman plumber license (4 years apprenticeship + exam) plus a master plumber license (1-2 more years + exam) to run your own business. JATC apprenticeship programs are typically free and you earn $15-25/hour while learning. This is the path — don’t skip it.

Business entity: LLC (limited liability is critical in plumbing — you can flood a house). Cost: $100-200.

Insurance: General liability ($1-3M coverage, $1,200-2,500/year) + workers comp if you hire ($2,000-6,000/year). Both are mandatory. Some states require a surety bond as well.

Vehicle: Service van (Ford Transit, Ram ProMaster, or Mercedes Sprinter) with organized tool shelving. Your van is your first impression. A beat-up truck signals a side-hustler; a clean van with your logo signals a professional. Budget: $30,000-60,000 new, or $15,000-25,000 for a well-maintained used van.

Tools: You’ve accumulated most of these during your apprenticeship. Add specialized service tools: pipe threading machine, pipe inspection camera ($300-1,500), ProPress or SharkBite fittings for fast copper work, cordless drill/driver set, and a full wrench kit.

Step-by-Step Roadmap

Before anything: Get your master plumber license if you don’t have it. This is non-negotiable in most states to operate your own company.

Month 1: Register your LLC. Get insurance. Buy or lease your service van. Have your van lettered (magnets are fine to start: $80-120, professional lettering: $400-800). Build a basic website — clients Google “licensed plumber [city]” before calling.

Month 2: Set up Google Business Profile. Get your first reviews from family, friends, former coworkers who’ve seen your work. Start marketing: direct mail to homeowners in your target zip codes ($0.40-0.80 per piece), Nextdoor, Facebook neighborhood groups.

Month 2-3: Your first jobs will come from referrals from your network — former employers (who may refer overflow work), contractors, real estate agents, and property managers. These relationships are gold. Cultivate them aggressively.

Month 3-6: Build recurring commercial accounts. Property management companies, small apartment buildings, and HOAs provide consistent monthly revenue with predictable work. One property management company with 50 units can send you 10-20 service calls per month.

Startup Costs Breakdown

Item	Cost
Master plumber license (if not yet obtained)	Varies ($50-500 for exam fees)
LLC registration	$100-200
General liability insurance	$1,200-2,500/yr
Workers comp (when you hire)	$2,000-6,000/yr
Service van (used)	$15,000-30,000
Van lettering/signage	$400-800
Tool inventory build-out	$3,000-8,000
Initial parts inventory	$500-1,500
Website + Google Business Profile	$0-300
Total	$22,200-49,300

This is the most capital-intensive business on this list. A business loan or line of credit is common for the vehicle purchase. Your first 90 days of revenue will quickly service the debt.

How to Get Your First 10 Customers

Your network is everything at launch. Tell everyone: former coworkers from your apprenticeship, family, friends, your dentist, your kids’ coach. “I just started my own plumbing company. If you ever need anything, I’d love to earn your business.” This feels awkward exactly once. After that, it’s just how business works.

Real estate agents and property managers are your highest-value referral sources. A single agent who closes 30 homes/year will send you 15-20 plumbing calls just from their buyer clients in year one. Take them to lunch. Give them your personal cell number. Be the plumber who answers the phone at 7 PM on a Friday — they’ll never call anyone else.

Home warranty companies (AHS, First American) need licensed plumbers. The rates aren’t great ($35-50 service call fee that comes out of your invoice), but the volume is consistent and it builds Google reviews fast.

Direct mail to specific neighborhoods. Target zip codes with older housing stock (1960s-1990s homes). These houses have galvanized pipe, aging water heaters, and cast iron drains that regularly need attention. A simple postcard: “New local licensed plumber. $75 off first service call. [phone + website].”

Google Local Service Ads — these are “Google Guaranteed” ads that show at the very top of search. For plumbing, they convert at 15-25% and cost $15-30 per lead. Worth it once you’re established.

Pricing Guide

Service call fee: $75-125 (credited toward work performed)
Labor rate: $75-150/hour (market-dependent)
Drain cleaning (basic): $150-250
Water heater replacement (tank): $800-1,500 installed
Water heater (tankless): $1,500-3,500 installed
Toilet repair: $150-300
Toilet replace: $400-700 installed
Sewer line camera inspection: $150-300
Full repipe (whole house): $8,000-20,000

Don’t compete on price. Licensed plumbers who are available, reliable, and clean in their work can charge top of market. Your clients are not primarily price-shopping — they’re shopping for someone trustworthy who won’t make the problem worse.

Tools & Equipment

Basic tools: pipe wrenches, channel locks, drill, reciprocating saw, copper pipe cutters
Drain tools: drum machine, electric snake, handheld auger
Camera inspection: Ridgid SeeSnake or RIDGID micro camera
ProPress: Viega ProPress for fast copper joining (saves hours on jobs)
Leak detection: thermal camera or acoustic detection meter
Software: ServiceTitan (industry standard, $100-200/mo) or Jobber ($50/mo)

Common Mistakes to Avoid

Undercharging because you feel awkward about rates. Your license took 4-5 years to earn. Your insurance, van, and tools represent $30,000+ in investment. Charge accordingly. $75/hour is the floor, not the ceiling.

No flat-rate pricing. Homeowners hate “I don’t know how long it’ll take” answers. Develop a flat-rate price book for common jobs (toilet repair, water heater swap, drain clean). It closes faster and eliminates arguments.

Being a yes machine. Know which jobs you do well and focus there. Residential service calls, repipes, water heaters — master these before taking commercial plumbing contracts that require different skills and bonding.

Not following up on estimates. 40% of estimates never convert simply because no one follows up. Send a text 3 days after every estimate: “Hi [name], just checking if you had any questions about the estimate for [job]. Happy to schedule when you’re ready.”

Ignoring invoicing and cash flow. Residential clients pay at service. Commercial clients often pay net-30. Know your terms and enforce them. Late invoices kill small service businesses.

Growth Path: From Solo to Team

Year 1: You’re a solo operator doing 3-5 service calls per day. Revenue: $8,000-15,000/month. More than most jobs pay.

Year 2: Hire your first helper (apprentice or assistant). You focus on skilled work; they handle the labor. Revenue climbs to $15,000-22,000/month.

Year 3: Second service truck, second licensed tech. You’re estimating and managing. Revenue: $25,000-45,000/month.

Year 5+: You’re running a plumbing company — multiple trucks, an office manager, possibly a commercial division. Many owners at this stage are working on their business more than in it.
