Window cleaning

Window cleaning combines one-off jobs with regular storefront and residential routes. Route density and safe work at height matter most.

80% took in less than $25,000 for the whole year — many are side or part-time businesses. If you plan to do this full time, your plan needs sales well above the middle. The local plan works out exactly how much.

What these numbers are — and aren’t. Sales (receipts) before any expenses: not profit, and not what the owner takes home. Counts every business with no paid employees that filed a tax return, including side businesses. The Census Bureau adds a small amount of noise to protect privacy. Businesses with employees aren’t included.

Main caution: Work at height carries real injury risk. Check what insurance and training you need before working above ground floor.

What it costs to run

These are the categories to price with local quotes. The plan lists every one of them for you.

Every job

  • Solutions and squeegee rubbers
  • Travel (fuel, mileage)
  • Helper pay per job
  • Other per-sale costs

Every month

  • Insurance (liability and commercial auto)
  • Vehicle (business share)
  • Phone and internet
  • Scheduling, invoicing and payment software
  • Ongoing marketing
  • Bookkeeping and tax preparation
  • Other monthly costs

To start

  • Ladders, water-fed pole and tools
  • Safety gear
  • Business registration and local licenses
  • Website, logo and booking or store page
  • Other one-time costs

Your own pay is part of the cost, too. The plan works out the price that covers it — or start with how much to charge for window cleaning.

Licenses, insurance and rules to check locally

Requirements differ by state, county and city. Check two layers:

1. Your own license, if the work needs one

Some work needs a personal license or certificate (a food-handler card, for example). Search the CareerOneStop License Finder (US Department of Labor) for your kind of work and state.

2. Business licenses, permits and insurance

Start with the SBA: Apply for licenses and permits guide, then your city or county. Questions to answer:

  • Does your city or county require a general business license or registration?
  • What liability insurance and fall-protection rules apply to work at height?
  • If you hire, what are your state’s rules for workers’ compensation, payroll taxes and worker classification?

Check local prices before you set yours

Get three real prices from window cleaning businesses near you, the way a customer would: their websites, a quote request, local listings and review sites, or neighborhood groups. Note what each price includes. Enter them in your local plan — it shows where your price sits and whether your costs leave room to compete.

Test demand before you spend

Offer your first few jobs at your real price to people who match your customer — not discounted favors for friends — before investing in more equipment or marketing.

Decide your pass mark before you start — for example, a set number of paid jobs within 30 days.

Questions your local plan has to answer

  • What do local competitors charge? Ask for quotes the way a customer would.
  • How long does each job take you, including travel and preparation?
  • How many jobs can you deliver in a week at a quality you’re proud of?
  • How will customers find you, and what will it cost to win each one?
