Start a Window Cleaning Business in New Hampshire
Low startup costs, high profit margins, and steady demand in New Hampshire.
Window cleaning is one of the lowest-cost businesses to start—basic equipment runs $1,060-$10,600 in New Hampshire. Profit margins of 50-70% are common since labor is the main cost.
