Market Opportunity in New Hampshire
New Hampshire’s aging housing stock (over 40% built before 1970) creates constant demand for plumbing repairs, repiping, and fixture upgrades. The state’s population grew 4.6% from 2010 to 2020, concentrated in the southern tier along the I-93 and Route 3 corridors. Severe winter freezes cause burst pipes, driving emergency service calls from November through March. New construction in suburbs like Bedford, Windham, and Derry also fuels new-work plumbing. However, the market is highly seasonal—summer and fall see more new construction and renovations, while winter spikes emergency work. The challenge: skilled plumbers are scarce, with the NH Department of Labor reporting a shortage of licensed master plumbers, which means less price competition and higher margins for those who get licensed.
State Licensing & Legal Requirements
You must register with the New Hampshire Board of Plumbers and Gas Fitters under the Office of Professional Licensure and Certification (OPLC). Requirements:
- Licensing: You need a Master Plumber license (or hire a licensed master) to operate a business. To qualify, you need 4 years (8,000 hours) of plumbing experience under a licensed master and pass the NH Master Plumber exam. If you are a journeyman, you can work as an employee but cannot hold a contractor license.
- Business Registration: Register your business name with the NH Secretary of State (Corporation Division) – $50 online filing. If using a DBA, file at the county level.
- Permits: Each municipality requires a plumbing permit for any job (e.g., Manchester, Nashua have separate permit offices). Pull permits as needed.
- Bond: A $2,000 surety bond is required by the Board of Plumbers and Gas Fitters. File the bond form with your license application.
- Insurance: General liability insurance minimum $1,000,000 aggregate; commercial auto insurance; workers’ compensation if you have employees (mandatory in NH if you have one non-family employee). NH does not require disability insurance.
- EPA Certification: For refrigerant handling (HVAC plumbing overlap), but not required for standard plumbing.
Startup Costs
Budget between $12,000 and $25,000 to start lean. Itemized:
- Vehicle: Used cargo van or pickup (2010-2016) – $5,000–$12,000. Add racking/shelving $500–$1,000.
- Equipment: Basic pipe wrenches, drain snake, auger, power tools (reciprocating, pipe cutter), tubing bender, torch kit – $2,000–$3,500. Pro press tool rental or purchase $1,500–$4,000 if needed.
- Insurance: First year general liability + commercial auto – $1,800–$3,200 (higher near coast).

- Permit deposits: $200–$500 for initial municipal registrations.

Revenue Potential in New Hampshire
Average job ticket: $350–$550 (typical service call including diagnostic and minor repair). Emergency after-hours calls average $450–$750. New construction rough-in per fixture runs $150–$250.
Market rates by region: Seacoast (Portsmouth, Dover) commands 10–15% higher rates due to cost of living – typical service call $400–$600. Manchester/Nashua moderate – $350–$500. North Country (Berlin, Littleton) lower – $300–$450 but less competition.
Path to $5k/month: 12-15 small service calls per month at $350 avg. Focus on drain cleaning and toilet repairs (quick, repeatable).
Path to $10k/month: Mix of 10 service calls ($350 avg) + 2 larger remodels ($2,000–$3,000 each) or 3 emergency calls ($500 avg). You need to add a part-time apprentice or work 50+ hours.
