You've spotted a gap in the market: homeowners and contractors need reliable repiping specialists, and the barrier to entry is lower than you'd think. Starting a repiping business requires hands-on expertise, the right certifications, and smart financial planning—but not a massive upfront investment if you're strategic. Here's exactly what you need to do to get your first jobs and scale.
Get Your Licensing and Certifications First
Before you land a single contract, you need to be legally qualified. Requirements vary by state, but most require a plumbing license, often at the master or journeyman level. This typically involves 4,000–10,000 hours of apprenticeship (paid work under a licensed plumber), passing a trade exam, and a state application fee ($100–$500).
If you're already licensed, verify your credentials cover repiping specifically. Some states distinguish between general plumbing and specialized repiping services. If you're new to the trade, apprenticing with an established repiping contractor accelerates your real-world knowledge of galvanized-to-PEX transitions, polybutylene replacements, and code compliance across different jurisdictions.
Invest in Essential Tools and Equipment
You don't need a warehouse to start. A solid repiping toolkit runs $2,000–$5,000:
- Press tools and fittings for PEX or copper lines ($800–$1,500)
- Pipe cutters, benders, and crimpers ($300–$600)
- Inspection camera (used, $400–$800) to diagnose before quoting
- Basic hand tools, flashlights, and safety gear ($300–$500)
- Tool bags and portable workbench ($200–$400)
A used van or truck is non-negotiable: budget $3,000–$8,000 for a reliable model with cargo space. Add tool racks, shelving, and branding ($500–$1,000). Total hard costs: $6,000–$15,000 to operate independently.
Get Insurance and Bonding
Repiping involves high-value work inside homes. Liability insurance costs $500–$1,500 per year for a solo operator. A surety bond ($300–$1,000 annually) protects clients if you fail to complete contracted work. Workers' compensation (if you hire staff) runs 15–30% of payroll, depending on your state.
Don't skip this. A single water damage claim can bankrupt a startup; insurance is your survival mechanism.
Price Your Services Competitively
Repiping labor ranges from $75–$200 per hour, depending on your region and reputation. Full-house repiping (typically 2,000–3,000 square feet) costs homeowners $8,000–$15,000 total, with $4,000–$8,000 in labor.
Charge by the job, not hourly, once you've quoted 10–15 similar projects. This protects you from low-balling and rewards efficiency. Always include a site visit estimate ($50–$100 fee, waived if they hire you) to account for crawl-space access, wall cuts, and permit requirements.
Build Your Lead Generation Engine
Word-of-mouth and local contractor relationships are your first customers, but you need a system to scale. List your services on platforms where homeowners and contractors actively search—platforms like Mercoly connect you with high-intent leads, help you win jobs, and let you sell materials and finished services in one place.
Beyond that: create a simple website with before-and-after photos, get on Google Business Profile, and ask satisfied clients for reviews. Every five-star review is a lead magnet. Partner with water heater companies, real estate agents, and property managers to get referral pipelines.
Manage Cash Flow Early
Your first 90 days will be tight. Materials might cost $2,000–$4,000 per job upfront; you'll invoice at completion or net-30. Keep $5,000–$10,000 in a business account for materials and unexpected repairs. Never finance customer work with personal credit; it's a common failure point for young trades.
Hire Strategically—Or Work Solo First
Stay solo for 6–12 months if you can. Once you're turning away jobs, hire an apprentice or licensed assistant ($18–$28/hour). This doubles your capacity without 50% overhead until revenue justifies it.
Frequently Asked Questions
Q: What's the biggest difference between copper repiping and PEX installation? Copper is more durable (50+ years) but costs 30–40% more; PEX is faster to install, cheaper, and handles temperature swings well, but some jurisdictions cap it to certain zones. Quote both options.
Q: How do I estimate a repiping job quickly without spending an hour on-site? Ask the homeowner about the home's age, current pipe material (visible under sinks/basement), any water pressure issues, and rough square footage, then add 20% buffer to your estimate—repiping always uncovers surprises.
Q: Can I start a repiping business part-time while employed? Yes, but only if your full-time employer permits side work and your state's licensing rules allow it; many don't allow licensed plumbers to run unlicensed side gigs, so verify first.
