Start a Pressure Washing Business in New Hampshire
April-October, peak April-June season in New Hampshire.
New Hampshire's no income tax and no sales tax make it one of the most business-friendly states in New England. Southern NH (Manchester, Nashua) is essentially a Boston suburb—affluent commuters who expect professional services and are willing to pay. The season mirrors Maine's: April-October with peak spring demand. Harsh winters leave salt, sand, and grime on everything. Coastal Portsmouth has salt air damage year-round. The market is less saturated than neighboring Massachusetts, and you can serve both states from a southern NH base. LLC filing is $100, and no state pressure washing license is required.
Important Notices
No Income Tax + No Sales Tax
New Hampshire has no state income tax and no sales tax. Your take-home profit per job is higher than neighboring states. Factor this into your business plan—it's a real competitive advantage.
Surface Damage Liability
High pressure destroys vinyl siding, painted surfaces, and wood. Learn which surfaces need soft washing (low pressure + chemicals) vs. high pressure. One mistake can cost you thousands.
Insurance Is Non-Negotiable
You're spraying high-pressure water at people's most expensive asset (their home). One broken window, damaged siding, or slip-and-fall without insurance can bankrupt you.
