Window cleaning is one of the more profitable small service businesses you can start, with net profit margins typically landing between 20% and 25%. That’s well above many service industries, largely because startup costs are low, overhead stays manageable, and pricing per job is surprisingly strong. Solo operators in urban areas commonly earn $40,000 to $80,000 annually, with room to grow significantly once they add employees or commercial accounts.
What You Can Realistically Earn
A solo window cleaner working full-time in a mid-size or large metro area can expect to bring in $40,000 to $80,000 per year. That range depends heavily on how many jobs you book per day, your local market rates, and whether you work year-round or deal with seasonal slowdowns. Operators who focus exclusively on residential work tend to land in the lower half of that range, while those who mix in commercial storefronts or post-construction cleanup push toward the higher end.
The 20% to 25% net profit margin means that for every $1,000 you bill, roughly $200 to $250 stays in your pocket after paying for insurance, fuel, supplies, and any other expenses. That margin improves as you get more efficient with routing, build a base of repeat customers, and reduce the time you spend on unpaid tasks like quoting and driving between jobs.
How Much Jobs Actually Pay
The average residential window cleaning visit runs about $221, with most jobs falling between $150 and $302. That’s a solid ticket price for work that often takes one to three hours. Here’s how pricing typically breaks down by window type:
- Standard single- or double-hung windows: $4 to $8 per window
- Large picture, bay, or bow windows: $10 to $20 per window
- Multi-pane windows with grids: $8 to $15 per window
- Skylights: $20 to $30 per window
- High-rise or specialty access (above three stories): $15 to $40 per window
Cleaning both interior and exterior sides of a standard window runs $8 to $16, roughly double the price of doing just one side. Post-construction cleanup, which involves removing paint overspray, stickers, and construction dust, commands $12 to $20 per window because of the extra time and care involved.
Most professionals also set a minimum service charge of $75 to $150. This protects your earnings on small jobs where the drive time and setup would otherwise eat into your hourly rate. A house with only six or eight windows might not generate much per-window revenue, but the minimum ensures you still walk away with a worthwhile amount for the visit.
Startup Costs Are Unusually Low
One reason window cleaning is so profitable is that you can launch for very little money. A basic setup costs $1,000 to $5,000, which is a fraction of what most service businesses require. That budget covers professional-grade squeegees, extension poles, buckets, a sturdy ladder, cleaning solution, and safety equipment.
Beyond gear, your initial spending includes business registration fees, general liability insurance, and basic marketing materials like business cards and a simple website. You don’t need a commercial vehicle right away. Most solo operators start with a personal car or truck and a bucket of supplies in the back. As revenue grows, you can invest in a water-fed pole system (which lets you clean upper-story windows from the ground) or a wrapped van that doubles as advertising.
Monthly Overhead to Expect
The biggest recurring cost is insurance. General liability coverage for a window cleaning business averages about $160 per month nationally, or roughly $1,919 per year. Your actual premium will vary by location, with rates ranging from around $139 to $186 per month depending on where you operate. General liability protects you if you accidentally break a window, damage a customer’s property, or if someone is injured on a job site. Most residential and commercial clients will ask for proof of insurance before hiring you, so this isn’t optional.
Other monthly costs include fuel, cleaning chemicals, and replacement supplies like squeegee rubbers and towels. Fuel is your second-largest variable expense and depends entirely on how spread out your jobs are. Tight geographic routing, where you cluster appointments in the same neighborhood or part of town, can cut fuel costs dramatically. Cleaning solutions and replacement parts are relatively cheap, usually running a few hundred dollars per month at most for a solo operator.
If you’re booking jobs through a website, add in modest costs for web hosting, a scheduling tool, and possibly a small advertising budget for local search ads. All in, most solo operators keep total monthly overhead between $500 and $1,500, which is manageable against even a modest job schedule.
What Makes Some Operators More Profitable
The gap between a $40,000 year and an $80,000 year often comes down to a few specific choices. Recurring service agreements are the biggest lever. A customer who books quarterly cleanings is worth four times as much as a one-time job, and you spend zero time or money acquiring them after the first visit. Building a roster of 80 to 100 recurring residential clients can create a stable, predictable income base.
Commercial work, particularly storefronts and small office buildings, tends to pay on a regular schedule (weekly or biweekly) and involves simpler, faster work than residential jobs with dozens of different window types. A single commercial route of 10 to 15 storefronts can generate steady weekly income with minimal driving between stops.
Pricing discipline matters too. New operators often underprice to win jobs, but charging $4 per window when the market supports $6 to $8 means leaving thousands of dollars on the table over a year. Reviewing and adjusting your rates annually to reflect changes in fuel, insurance, and supply costs keeps your margins healthy as expenses rise.
Growing Beyond Solo Work
The math shifts when you hire your first employee or subcontractor. Labor becomes your largest expense, but it also lets you serve more customers per day without doing all the physical work yourself. The key is making sure each crew member generates enough revenue to cover their wages, payroll taxes, workers’ compensation insurance, and a portion of overhead, while still leaving profit for the business.
A common approach is to keep doing jobs yourself while sending an employee to handle simpler residential routes. This lets you take on higher-value commercial or specialty work while your team handles the bread-and-butter accounts. Owners who scale to two or three crews often push total business revenue well above six figures, though net margins may dip slightly as labor and management complexity increase.
The transition from solo operator to business owner with employees also brings new costs: workers’ comp premiums, payroll software or a bookkeeper, additional vehicle expenses, and more equipment. Planning for these expenses before you hire ensures you don’t grow yourself into a cash flow problem.
Seasonal Patterns and Demand
Window cleaning demand peaks in spring and early summer, when homeowners want their windows cleaned after winter, and again in fall before the holidays. In warmer climates, demand stays relatively steady year-round. In areas with harsh winters, you may see a significant dip from December through February.
Smart operators fill slow months by adding complementary services like gutter cleaning, pressure washing, or holiday light installation. These use similar skills and equipment, and your existing customer base is the easiest audience to sell to. Diversifying your service menu can smooth out seasonal revenue dips and keep your annual income closer to the top of the earning range.
