Plumbing is the highest-demand home service in America. Full stop. There isn't a neighborhood in this country where homeowners aren't waiting two weeks for a plumber to return their call, paying premium prices for mediocre work, and desperately wishing there was someone reliable they could actually trust.
This is a $130 billion industry — and it's structurally undersupplied. The aging workforce, low new-entrant rates, and exploding housing stock have created a gap that independent operators are uniquely positioned to fill. If you have a plumbing license (or a path to one), starting your own plumbing business in 2026 is one of the best business decisions you can make.
This guide is how to actually do it. Not a sanitized listicle, not a franchise brochure dressed up as advice — a real, step-by-step framework from people who've been in the home services industry for over two decades, across ownership, brokerage, and franchise consulting. We've seen what works, what fails, and what separates a $100K/year owner-operator from a $2M/year multi-truck operation.
And yes, we'll address the franchise question immediately, because you're going to get pitched on it the moment anyone finds out you're starting a plumbing company.
The Franchise Math (Read This Before Anyone Sells You Something)
The three biggest plumbing franchise brands are Roto-Rooter, Mr. Rooter, and Benjamin Franklin Plumbing. Here's what they actually cost to buy into:
| Brand | Initial Franchise Fee | Total Startup Investment | Ongoing Royalty |
|---|---|---|---|
| Roto-Rooter | $40,000–$85,000 | $75,000–$300,000+ | ~7% of gross revenue |
| Mr. Rooter | $30,000–$75,000 | $75,000–$200,000 | 5–6% of gross revenue |
| Benjamin Franklin | $35,000–$75,000 | $100,000–$250,000+ | 6% of gross revenue |
Now let's do the actual math. Say you build a solid 3-truck plumbing operation doing $1.2M/year in revenue. At 6% royalties, you're writing a $72,000 check to the franchisor annually — every year, forever, for the duration of your franchise agreement (typically 10 years). That's $720,000 over the life of the contract.
What are you getting for that? A brand name in your market, a field operations manual, some marketing templates, and a system you could have built yourself for a fraction of the cost.
Franchises are a shortcut for people who don't know the industry and want to buy a proven system. If you already have plumbing skills and trade knowledge, you're paying $200K for things you could build yourself. The only thing you can't replicate is the brand name — and in local service businesses, your brand is your name and your reviews, not a national chain.
We're not anti-franchise in principle. For someone with no industry experience, a proven system and built-in support structure has real value. But if you're a working plumber, a journeyman with years of field experience, or someone who knows the trade and just needs the business infrastructure — you're much better off going independent and building something you actually own 100% of.
How to Start a Plumbing Business: 9 Steps
Here's the real path from "I have a license and some tools" to a legitimate, growing plumbing company.
Get (or Verify) Your Licensing
This is non-negotiable and the most variable part of starting a plumbing company. Every state has different requirements. Here's what the landscape actually looks like:
- Journeyman Plumber License: Most states require 2–5 years of apprenticeship (8,000–10,000 hours) plus a written exam. This lets you work under a master plumber.
- Master Plumber License: Typically requires 1–2 additional years beyond journeyman (or total of 5–7 years), plus an additional exam. In most states, you need a master license to run your own business.
- Contractor's License: Many states require a separate contractor's license (or plumbing contractor license) beyond the trade license. Check your state's contractor licensing board.
- Bond: Most states require a surety bond ($5,000–$25,000 face value, costs $150–$500/year to carry).
Use our state-by-state tool to get the exact requirements for your state:
Form Your Business Entity
Do this before you take your first paid job. No exceptions.
- LLC: This is what most single-operator plumbing companies should use. $50–$200 to file in most states, protects your personal assets, simple to manage.
- EIN: Get a free Employer Identification Number from IRS.gov. You need this for your bank account, taxes, and hiring.
- Business bank account: Keep business and personal money completely separate from day one. This is the difference between a business and a mess.
- DBA (if needed): If you're operating under "Smith Plumbing" but your LLC is "Smith Home Services LLC," file a DBA with your county clerk.
Get the Right Insurance
You need at minimum two types of insurance before your first job:
- General Liability Insurance: $500,000–$1M minimum coverage. Covers property damage you cause on the job (and you will, eventually). Budget $100–$200/month for a solo operator.
- Commercial Auto Insurance: Your personal auto policy won't cover your work truck on the job. Non-negotiable. Budget $150–$300/month depending on truck value and your driving history.
- Workers' Comp: Required in most states the moment you hire your first employee. Some states require it even for sole proprietors. Check your state's requirements.
- Tools & Equipment Coverage: Add-on that covers your tools if they're stolen from the truck. Cheap and worth it.
Get insurance certificates immediately. Most homeowners and property managers will ask for proof of insurance before letting you on-site. Having a clean PDF ready to send is a trust signal that closes jobs.
Set Up Your Truck and Tools
You don't need a brand-new truck or a $50,000 tool inventory to start. Here's what a solid residential service setup actually costs:
| Item | Budget Range | Notes |
|---|---|---|
| Used service truck (van or pickup) | $8,000–$18,000 | High-top van preferred for service work |
| Hand tools (wrenches, pliers, cutters) | $800–$1,500 | Don't cheap out on your core tools |
| Power tools (drill, rotary hammer) | $400–$800 | Buy a solid 18V cordless platform |
| Drain snake / cable machine | $300–$1,200 | Used Ridgid K-400 is the workhorse choice |
| Toilet auger | $40–$80 | Basic, but you'll use it constantly |
| Pipe camera (inspection) | $400–$1,500 | Optional to start; adds upsell opportunities |
| Press tool or torch kit | $500–$1,200 | Depends on your local code and work type |
| Shop vac + water pump | $200–$400 | Essential for emergency calls |
| Truck shelving / organization | $400–$1,500 | Adrian Steel, Ranger Design, or DIY |
| Total (conservative start) | $11,000–$26,000 | Truck + tools to take real jobs |
Buy used equipment where it makes sense (trucks, pipe cameras, drain machines). Buy new where quality matters (hand tools, safety equipment). A beat-up truck with sharp tools is far better than a shiny truck with garbage wrenches.
Price Your Services Correctly (From Day One)
Most new plumbers underprice themselves because they're scared of losing jobs to more established competitors. This is a slow-motion bankruptcy strategy. Price based on your real costs, not on fear.
Here's what the market actually supports in most mid-size U.S. markets:
- Service call / diagnostic fee: $150–$250 (charged on arrival; applies to repair)
- Drain cleaning (kitchen/bath): $150–$350
- Toilet repair or replacement: $200–$500+ (fixture not included)
- Faucet repair or replacement: $150–$400 (fixture not included)
- Water heater replacement (standard tank): $1,200–$2,500 installed
- Tankless water heater install: $2,500–$5,000+
- Full fixture rough-in (new construction): Price per fixture, $300–$700
- Sewer line replacement: $3,000–$15,000+ depending on depth and length
- Emergency / after-hours rate: 1.5–2x standard rate
Use a flat-rate pricing book from day one — not time-and-materials. Flat-rate pricing protects you when jobs take longer than expected, builds trust with customers (they know the price before you start), and is far easier to explain on the phone.

Get Your First Customers
The first 90 days is about building your local digital presence and your referral engine simultaneously. Here's the exact sequence:
Week 1–2: Google Business Profile (GBP)
Claim and fully optimize your Google Business Profile before you spend a single dollar on advertising. This is the highest-ROI move in local service marketing, period. Fill every field: business description, services, service area, hours, photos of your truck and your work. GBP is how people find emergency plumbers at 10pm.
Month 1: Nextdoor + Neighborhood Marketing
Join Nextdoor as a local business and post an introduction in your service area. Print 500 door hangers for the zip codes you want to own and hit them on a Saturday morning. Your cost: ~$150 in printing and a few hours walking. Your return: often 2–5 jobs in the first 30 days from the targeted neighborhoods.
Ongoing: Reviews are your currency
Ask every satisfied customer for a Google review — at job completion, while you're still on-site. Not via email later. Right then. Hand them your phone with the review page open if needed. A plumbing company with 50 reviews showing 4.8 stars gets 3–4x more calls than a company with zero reviews, even if the reviews-zero company is technically better. Reviews are trust made visible.
- Google Business Profile claimed and 100% complete
- 5 photos uploaded (truck, tools, team, work results)
- Service area defined in GBP settings
- Door hanger campaign in 2 target zip codes
- Nextdoor introduction posted
- Ask for a Google review on every completed job
- 10 reviews collected (aim for this in month 1)
- Business card + invoice template branded and ready
Build Recurring Revenue Early
The biggest difference between a plumber grinding $8K/month and one who predictably does $25K/month is recurring revenue. Start building it in your first 6 months:
Annual Maintenance Agreements: Offer a $179–$299/year plumbing checkup plan that includes an annual inspection, priority scheduling, and a discount on service calls. Sold correctly to homeowners with aging pipes or water heaters, this is an easy close — and it locks in a customer relationship worth $5,000–$15,000 in lifetime value.
Commercial Accounts: Restaurants, property management companies, and small landlords with multi-unit properties need a reliable plumber on call. These accounts are sticky — once you're the plumber for a 20-unit apartment building, you get every call. Reach out directly to small property management companies in your area.
Water Heater Replacement Programs: Any water heater over 8 years old is a replacement opportunity. When you service a call on an older heater, price the repair AND the replacement. Many homeowners will choose the replacement when the math is presented clearly.
Hire Your First Helper
At some point (usually when you're turning away jobs), you need to add capacity. Your first hire is the hardest decision — here's how to think about it:
- Helper/Apprentice first: Your first hire doesn't need to be a licensed plumber. A reliable, hardworking helper at $18–$24/hour can dramatically increase your capacity — they dig, schlep, hold, cut, and prep while you do the licensed work. You'll easily bill out 2–3x their hourly cost on every job.
- The revenue trigger: Hire when you're consistently turning down work or losing jobs to scheduling constraints — not before. A good benchmark: if you've had to turn down 3+ jobs in a week for 2 consecutive weeks, it's time.
- W-2, not 1099: Unless you have a lawyer tell you otherwise for your specific situation, pay employees as W-2. Misclassifying employees as independent contractors is one of the most common (and expensive) legal mistakes in the trades.
Scale to Multiple Trucks
Going from 1 truck to 3 trucks is a qualitative change, not just a quantitative one. You stop being a tradesman and become a business operator. The things that matter at this stage are different from the things that mattered in your first year:
- A dispatching system that can schedule and route multiple trucks efficiently (ServiceTitan, Housecall Pro, or Jobber)
- Standard operating procedures so your technicians deliver consistent quality without you on every job
- A CSR or answering service so you're not personally answering phones while installing a water heater
- Financial controls — job costing, gross margin by job type, actual labor efficiency tracking
- A real marketing budget ($2,000–$5,000/month in Google Local Service Ads is the right level for a 3-truck operation)
Realistic Revenue Projections: Solo to Multi-Truck
Here's what the numbers actually look like at each growth stage. These are real ranges from real plumbing businesses — not optimistic projections from a franchise brochure.
| Stage | Monthly Revenue | Monthly Net Profit* | What This Looks Like |
|---|---|---|---|
| Solo operator (Year 1) | $8,000–$15,000 | $4,000–$8,000 | 3–4 calls/day, 5 days/week |
| Solo operator (Year 2–3) | $18,000–$28,000 | $9,000–$15,000 | Fully booked, good reviews, some recurring |
| 2-truck operation | $45,000–$80,000 | $12,000–$22,000 | Owner managing + 1 lead tech + 1 helper |
| 3–5 truck operation | $120,000–$300,000 | $22,000–$55,000 | Owner off the tools, managing the business |
| Full regional company | $350,000–$750,000+ | $60,000–$120,000+ | Multiple locations, dedicated CSR team |
*Net profit after vehicle costs, insurance, parts/materials, and labor. Does not include owner compensation for field work (separate from business profit).
A fully booked solo plumber doing $22,000/month in revenue with 40% net margin is making $8,800/month in profit — plus their own labor income from jobs. Total owner income: often $120,000–$160,000/year in Year 2–3. That's better than most franchise agreements produce, and you own 100% of the business.
The Systems Every Plumbing Business Needs
Here's the uncomfortable truth about why good plumbers fail in business: the trade skills that make you excellent in the field have almost nothing to do with the management skills that make a business succeed. Running a plumbing company is a systems problem, not a technical problem.
The nine core systems every home service business needs to run like a real company:
- Estimating & Pricing System — Flat-rate book with job times and material costs built in. No more making up prices on the fly.
- Scheduling & Dispatch System — Who goes where, when, and in what order. Reduces drive time and increases billable hours.
- Customer Communication System — Automated appointment confirmations, on-my-way texts, and review requests. Most customers leave because of poor communication, not bad work.
- Job Tracking & Field Management — Digital invoicing, job notes, photos. Eliminates paper chaos and protects you legally.
- Financial Management System — Job costing, cash flow tracking, accounts receivable. Know your numbers or get eaten alive by them.
- Marketing & Lead Tracking System — Where are your leads coming from? What's your cost per lead? What's your close rate by lead source?
- HR & Hiring System — Application process, background checks, onboarding checklist, performance standards. Scales with you when it's time to hire.
- Training & Quality System — How do new technicians learn your standards? Consistent quality is what generates referrals.
- Customer Retention System — Annual maintenance reminders, seasonal outreach, referral programs. Turning one-time customers into lifetime customers.
Most independent plumbers have maybe 2–3 of these systems in any formal shape. The rest is handled by memory, habit, or not at all. This is the real advantage franchise systems sell — not the brand name, but the operational framework.
At HomePro, we've built all nine of these systems specifically for independent home service operators. The same framework you'd pay $200,000 to access through a plumbing franchise, available as a subscription — so you keep your independence and your margins.

How much does it cost to start a plumbing business?
A solo plumbing startup typically costs $10,000–$35,000 total: $8,000–$18,000 for a used service truck, $2,000–$5,000 for hand tools and basic equipment, $1,500–$3,000 for licensing and business formation, and $2,500–$5,000 for your first 6 months of insurance. With a $200–$400/month software budget for scheduling and invoicing, most operators are profitable within 3–6 months.
Do I need a license to start a plumbing business?
Yes — virtually every state requires a plumbing license, but the requirements vary widely. Most states require a journeyman plumber license (2–5 years of apprenticeship hours) plus a master plumber license to operate as a business. Some states let a master plumber hold the qualifying license for multiple technicians under their company. Use the SAHS state-by-state tool for exact requirements in your state.
Is a plumbing franchise worth it?
For most experienced tradespeople, no. Franchise fees for major plumbing brands run $75,000–$300,000 to start, plus 5–7% royalties on every dollar you earn — forever. The main value you're buying is a brand name and a system. If you already know the trade, you're better off building your own brand, keeping 100% of your revenue, and using a lower-cost system like HomePro for the operational framework. Franchises have real value for people with capital but no industry knowledge; for working plumbers, the math rarely works out.
How much can a plumbing business make?
A solo plumber doing 3–4 service calls per day can generate $15,000–$28,000/month in revenue. Owner-operator net profit typically runs 35–50% after parts, insurance, and vehicle costs — so $5,000–$14,000/month in profit, on top of your labor income from the jobs themselves. A 2-truck operation can produce $45,000–$80,000/month in revenue. At 5 trucks with an office manager, you're looking at $200,000–$350,000/month.
What equipment do I need to start a plumbing company?
For residential service work, start with: pipe wrenches (6", 12", 18"), channel-lock pliers, tubing cutter, drain snake/cable machine, toilet auger, press tool or soldering kit, water heater dolly, shop vac, and a reliable service truck with organized shelving. Budget $10,000–$25,000 total including the truck. Add a pipe inspection camera ($400–$1,500 used) when you can — it pays for itself quickly in diagnostic upsells.
How do I get my first plumbing customers?
Google Business Profile is the single highest-ROI move for a new plumbing company. Claim and fully optimize your listing before you spend a dollar on advertising. After that: Nextdoor for neighborhood trust, door hangers in your 2–3 target zip codes, and asking every completed-job customer for a Google review right then, on-site. Within 90 days of consistent effort, organic calls will start flowing and you'll have a steady referral base building underneath your paid leads.
