Sunlight hits a freshly squeegeed pane and the whole street seems to brighten, that satisfying squeak still ringing in your ears, a faint smell of vinegar solution drifting off your bucket. That’s the moment that hooks most window cleaners — clean, visible results in under ten minutes per window, and a business you can start for less than the cost of a used laptop.
The End Result: What You’re Building
A lean window cleaning business can realistically launch for $300-$600 in starter gear and generate $150-$400 per day working residential routes, often within the first month of steady marketing.
What You’ll Need to Get Started
- A quality squeegee and scrubber combo ($20-$40)
- An extension pole for second-story reach ($40-$80)
- Microfiber towels, a bucket, and eco-friendly cleaning solution ($30)
- Basic liability insurance ($300-$500 per year)
- A simple website or booking page (often free to start)
Step-by-Step: Launching on a Budget
Step 1: Practice Before You Charge
Clean your own windows and a friend’s house first. Speed and streak-free technique come from repetition, and showing up slow on your first paid job costs you a referral.
Step 2: Register the Business
Form a sole proprietorship or LLC ($50-$200 depending on your state) and get basic liability insurance before your first paid job — one broken window can cost more than a year of premiums.
Step 3: Price by the Window, Not the Hour
Most residential window cleaners charge $4-$8 per pane, or a flat $150-$250 for an average-sized home, both inside and out. Flat pricing builds trust faster than hourly rates with new customers.
Step 4: Find Your First Ten Clients
Neighborhood Facebook groups, Nextdoor, and flyers at local coffee shops cost nothing and often produce your first bookings within two weeks. Offer a modest first-job discount to convert lookers into bookings.
Step 5: Reinvest Before You Expand
Once you’re consistently booked, add a water-fed pole system ($400-$1,200) to handle taller properties faster and safer than a ladder — but wait until revenue supports it rather than financing it upfront.
Window Cleaning vs. Pressure Washing: Don’t Confuse the Two
New owners sometimes assume window cleaning and pressure washing are the same trade. They’re not. Pressure washing uses high-powered water jets for siding, driveways, and decks, requiring different equipment and a higher startup investment, often $2,000 or more. Window cleaning is far gentler, hand-tool based, and much cheaper to start.
Common Mistakes to Avoid
- Skipping insurance to save money — a single liability claim can end a new business.
- Underpricing to win early jobs, which trains customers to expect bargain rates permanently.
- Ignoring safety gear for second-story work, risking both injury and liability.
Frequently Asked Questions
How much does it cost to start a window cleaning business?
Most people launch for $300-$600 in basic equipment, plus insurance costs.
Is window cleaning profitable?
Yes — profit margins often exceed 70% once basic equipment is paid off, since ongoing costs are mainly solution and travel.
Do I need a license to clean windows?
Most states don’t require a special license, though local business registration and insurance are typically necessary.
How many windows can one person clean in a day?
An experienced solo cleaner can typically handle two to four residential homes per day.
Next Steps
Book your first five jobs at a slight discount, track your time per window carefully, and use that data to set sustainable pricing for the busy season ahead.
