Window Cleaning Cost Calculator
How to use this calculator
1. Enter Basic Information
- Property Name: Enter the property name for easy reference (default: “Lenny’s House”).
- Number of Windows: Input the total count of windows to be cleaned (maximum: 500). You can find this information by asking the home owner or walking the property and counting the number of windows. The default is set to 22 windows, which the EPA reports is the average number of windows for a single family home in the United States. But the type of window is also important in pricing. Adam Chapman from Pad Pals suggests counting each panel as a window when quoting a window cleaning.
- Price per Window: Set your base price per window (default: $15). According to Jessica Wimmer from This Old House, the national average is $8 – $40 per window for professional cleaning.

Understanding the formulas
Base Cost Calculation:
Base Cost = Number of Windows × Price per Window
Example: 20 windows × $15 = $300 base cost
Inside Cleaning Adjustment:
If Inside Cleaning selected:
Total Cleaning Cost = Base Cost × 2
Example: $300 × 2 = $600 for inside and outside
Additional fees:
Final Total = Total Cleaning Cost + Accessibility Fee + Condition Fee + Sum of Additional Service Fees
Example: $600 + $50 (accessibility) + $75 (condition) + $40 (additional services) = $765
How to quote window cleaning projects
Adam Chapman, the CEO of Ottawa’s top rated home service business Pad Pal, shares his process for quoting a window cleaning project below. The structure of this calculator lines up well with Adam’s approach.
Here are a few things to keep in mind when quoting window cleanings based on Adam’s real-world experience. By following this advice you can be confident you’re getting paid what you’re worth on these projects.
How to Count All the Windows
“Every single window pane counts as one window,” Adam says. Don’t let the sprawling architecture of a house overwhelm you. Whether it’s a bay window split into six panes or a solitary bathroom window, they each add up. Count them meticulously, because every single one adds time to complete the project.
Adam shares real invoices from paid jobs for various window cleaning projects on his Instagram.
Window Accessibility
“Noting where your ladders will go” is crucial, Adam points out. Are the windows easy to reach, or will you have to contort yourself like a yoga instructor just to get at them? If they’re within easy reach, great. But if you need to channel your inner acrobat, there’s an upcharge that’s justified by the extra effort.
Window Condition
“If the windows are very dirty, if there’s a post-construction cleanup, if there’s a lot of paint on the windows…” don’t just charge the standard rate. Adam is clear on this point… Extra grime means extra time! And extra time should mean extra fees for you. Make sure you’re accounting for the labor it will take to turn a neglected window into something the homeowner will be proud of.
Quotes by Window Type
This table provides a quick estimate for different window types based on the average number of panels and a rate of $15 per panel. You can see how using Adam Chapman’s approach to quotes could really benefit your bottom line.
| Window Type | Average Number of Panels | Cleaning Estimate ($15 per Panel) |
|---|---|---|
| Picture Window | 1 | $15 |
| Double-Hung Window | 2 | $30 |
| Bay Window | 4 | $60 |
| Sliding Window | 2 | $30 |
| Casement Window | 1 | $15 |
