Plumbing repair is a high-demand trade with low startup costs and fast cash flow—if you know how to launch it right. Most plumbers jump into the field with skills but struggle with the business side: licensing, insurance, pricing, and finding steady work. This guide walks you through every step to get your operation running and profitable.
Get Licensed and Insured
Before you pick up a wrench professionally, you need the right credentials. Licensing requirements vary dramatically by state and locality—some areas require a master plumber license, others just a contractor license, and some have less stringent rules. Check your state's Department of Labor or licensing board website for exact requirements. Most states require 4–5 years of apprenticeship or equivalent experience before you can sit for the exam.
General liability insurance is non-negotiable. Budget $400–$1,200 annually depending on your coverage limits and claims history. If you hire employees, you'll also need workers' compensation insurance (typically 10–25% of payroll). Don't skip this—one major injury claim without coverage can bankrupt a new business.
Register Your Business and Set Up Operations
Choose a business structure (sole proprietorship, LLC, or S-corp) based on tax and liability goals. An LLC costs $50–$150 to file in most states and provides personal liability protection. Register your business name with your state, obtain an EIN from the IRS, and open a dedicated business bank account.
Your startup toolkit should include:
- Van or truck with storage racks ($8,000–$25,000 used; $25,000–$50,000 new)
- Essential tools: pipe wrenches, crimpers, snake, auger, leak detection equipment ($2,000–$5,000 initial)
- Software for scheduling and invoicing (ServiceTitan, Jobber, or Housecall Pro: $50–$200/month)
- A phone line dedicated to the business
You don't need a physical office initially—run it from home and service calls from your vehicle.
Build Your Service Menu and Pricing
Define exactly what you'll repair and install. Common high-margin services include:
- Drain cleaning ($150–$300)
- Leak detection and pipe repair ($200–$600)
- Water heater repair/replacement ($400–$2,500+)
- Fixture installation (sinks, toilets, faucets: $150–$800+)
- Sewer line repair ($3,000–$10,000+)
Price based on your experience level and local market. Beginner plumbers typically charge $80–$120/hour; established operators with a strong reputation charge $150+. For service calls, add a diagnostic fee ($75–$150) to filter out tire-kickers and compensate you for travel time.
Research competitor pricing in your area by calling 5–10 local plumbers for quotes on a common job. This gives you realistic market rates and helps you position competitively.
Generate Leads and Get Found
Word-of-mouth is gold in plumbing, but you can't scale a business on referrals alone. Build a simple website listing your services, service area, and contact info. Google My Business is free and essential—claim your listing, add photos, and ask satisfied customers to leave reviews.
Post before/after photos of your work on Facebook and Instagram. Join local Facebook groups, answer plumbing questions, and include a soft call-to-action. Partner with property managers, real estate agents, and HVAC companies who can refer work to you.
Listing your services on Mercoly lets plumbing-focused customers find you, submit leads directly to your inbox, and sell both service contracts and products like water heaters or fixtures in one place—all without building separate sales channels.
Hire and Systemize
Once you're consistently booked, hire a second technician. Start with a part-time apprentice or licensed plumber at $18–$28/hour (depending on experience). Create simple checklists for common jobs so new hires deliver consistent quality.
Document your pricing, scheduling process, and communication scripts. This saves you time and prevents bad decisions when you're busy.
Frequently Asked Questions
Q: How much should I charge for a basic service call? A: Most established plumbers charge $100–$200 for a diagnostic call (30–60 minutes), then bill hourly ($80–$200+) or flat-rate for repair work. Your first call should always include a detailed estimate before work begins.
Q: What's the biggest expense I should expect in year one? A: Vehicle and tools ($10,000–$30,000), insurance ($2,000–$3,000 annually), and marketing ($500–$2,000). Everything else scales with customer volume.
Q: How do I compete against big plumbing companies? A: Focus on response time, personalized service, and a specific area where you become the go-to expert. Large companies often have slow scheduling; you can win jobs by answering phones quickly and showing up the same day.
