How to Start a Window Cleaning Business

What it takes to legally start a window cleaning business in the US — licensing, structure, EIN, taxes, insurance, and your first customers. The steps are the same everywhere; the forms and fees depend on your state, so pick yours below for the exact links.

  1. Check the licensing for window cleaning work

    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. This is the part that varies most by state — some require a state license or registration before you can advertise, others leave it to the city or county. Confirm both your state board and your local government before you take a job.

  2. Decide what the business needs to open

    Interior and exterior window cleaning for homes, storefronts, and low-rise commercial buildings, usually on a recurring schedule. The setup areas that usually matter for a window cleaning business: Local business license, Liability insurance ($1M typical for commercial), Water-fed pole system + ladders + squeegees, Route density planning, Recurring commercial contracts. Typical cost to get operational: $500–$4,000 (water-fed pole kit, ladders, professional squeegees, a vehicle you already own).

  3. Pick a structure — sole proprietor or LLC

    You can start as a sole proprietor with no filing, or form an LLC (usually $50–$300 depending on your state) for liability protection. For hands-on trade work where something can go wrong on a customer's property, most owners choose the LLC.

  4. Get a free EIN from the IRS

    An Employer Identification Number is free and takes a few minutes online. You need it to open a business bank account and to hire.

  5. Register for state taxes and get insurance

    Register with your state's tax agency if you'll collect sales tax, then line up general liability insurance — most contracts and license boards require proof of coverage.

  6. What window cleaning businesses charge

    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. Commercial is steady year-round; residential peaks spring and fall and before holidays. Storm and construction dust create bursts of demand.

  7. Get your first window cleaning customers

    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.

  8. 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.
