Dover is the fastest-growing city in New Hampshire, with a population exceeding 33,000 and a steady increase in both residential and commercial development. The Seacoast region experiences warm, humid summers with regular rainfall, but also periods of drought that make irrigation systems essential for lawns, gardens, and commercial landscapes. Many homes in Dover’s historic districts and newer subdivisions are equipped with underground sprinkler systems that require seasonal startup, winterization, and regular repairs. The market is moderately competitive, with a handful of established landscaping companies that offer irrigation services, but few specialize solely in repair. This creates an excellent opportunity for a niche-focused irrigation repair business. Average customer spend per repair call typically ranges from $150 to $450, with emergency services commanding a premium. Spring (April–June) and fall (September–November) are peak seasons due to system startup and blowout needs. Demand for drip irrigation and smart controller repairs is also growing as more homeowners adopt water-efficient systems.
You must register your business with the New Hampshire Secretary of State. Choose a business structure (sole proprietorship, LLC, or corporation). An LLC is recommended for liability protection. File the required forms online or by mail and pay the $100 filing fee (as of 2025). Obtain an Employer Identification Number (EIN) from the IRS if you plan to hire employees or form an LLC.
New Hampshire does not require a statewide license specifically for irrigation repair. However, if your work involves plumbing (e.g., tapping into water lines, installing backflow preventers), you may need a plumber’s license through the New Hampshire Board of Plumbers and Pipefitters. Check with the Dover City Hall for any local business permits. Additionally, if you apply pesticides or fertilizers, you must obtain a New Hampshire Pesticide Applicator License through the NH Department of Agriculture.
General liability insurance (minimum $1 million per occurrence) is essential. Also consider workers’ compensation insurance if you have employees, and commercial auto insurance for your service vehicle. Many Homeowner Associations (HOAs) in Dover require proof of insurance before you can work on their properties.
Register for a New Hampshire Business Tax ID (state does not have a general sales tax, but you must collect the Meals and Rooms Tax if you provide temporary lodging – not applicable for irrigation repair). You may need to register for Business Profits Tax (BPT) if your net income exceeds thresholds.
