  1. window cleaning license in New Hampshire: do you need one?

    Almost always just a local business license and liability insurance for ground-level and low-rise work. High-rise window cleaning (rope access, suspended platforms) is heavily regulated under OSHA and often requires specialized certification and much higher insurance — a different business entirely. In New Hampshire, the state board or agency that handles window cleaning licensing is linked below — check it, and your city or county business-license office, before you advertise or take a job. If New Hampshire doesn't license window cleaning work at the state level, a local business license (and often liability insurance) is still expected.

  2. What it costs to start a window cleaning business in New Hampshire

    Plan for $500–$4,000 (water-fed pole kit, ladders, professional squeegees, a vehicle you already own) to get operational. On top of that: about $100 to form a New Hampshire LLC, then charges a annual report (~$100)., a free EIN from the IRS, and general liability insurance — a few hundred dollars a year for most solo operators.

  3. What a window cleaning business needs before day one

    Interior and exterior window cleaning for homes, storefronts, and low-rise commercial buildings, usually on a recurring schedule. The parts that actually matter for window cleaning: Local business license, Liability insurance ($1M typical for commercial), Water-fed pole system + ladders + squeegees, Route density planning, Recurring commercial contracts.

  4. Form the business in New Hampshire

  5. What to charge for window cleaning in New Hampshire

    Storefronts $10–$40 per visit (small panes, frequent schedule); residential $150–$400 per home in-and-out by window count; commercial buildings bid per pane or per hour. Frequency drives the model — monthly beats one-time. Check what the established window cleaning businesses in your city actually charge before you set your rates — pricing to undercut them is the fastest way to work the first year at a loss.

  6. Getting your first window cleaning customers in New Hampshire

    Walk into storefronts with dirty windows and offer a first clean at a discount, plus Nextdoor and Google Business Profile for residential. Recurring commercial storefronts — restaurants, retail, offices on a monthly or biweekly schedule — are the stable base. Residential is higher per job but seasonal and less predictable. Commercial is steady year-round; residential peaks spring and fall and before holidays. Storm and construction dust create bursts of demand.

  7. The mistake most first-year window cleaning owners make

    Pricing residential one-time cleans as if they'll recur. They usually don't. Build the business on scheduled commercial routes and treat residential as bonus work, or you'll be prospecting from scratch every week.
