Pricing Overview
Simply put: most projects cost between $165 and $350. Professional window cleaners use 3 criteria when quoting a window cleaning: (1) house layout, (2) number of windows, and (3) time involved. Other contributing cost factors are the height of the windows, the accessibility, the window types, and how dirty they are. Sunrooms range from $50-$120, Skylights range from $10-$15, and Solar Panels range from $6-$10 per panel. Here’s a quick snapshot of what some of our clients have paid:

Window Cleaning Cost Factors
Several factors can determine the cost to clean residential windows, including how many windows you have, their size, and how dirty they are.
Number of Windows
Most professionals charge between $10 and $15 per window cleaned, but this amount varies depending on the size of each window and whether the windows include multiple panes (french). Decorative windows with individual panes will usually take longer than cleaning a single pane on a picture window.
Height
Window height and accessibility also help to determine your overall cost for cleaning. Generally speaking, higher windows that are difficult to access can increase the labor time and, as such, the cleaning cost. For example, floor-to-ceiling windows on the first floor will likely require a ladder or other equipment to access, taking more time than traditionally sized windows. There is also an element of danger to cleaning inaccessible windows, which factors into these upcharges.
Talk to your pro ahead of time and give them a heads-up regarding the accessibility of your windows.
Accessibility
Hard-to-reach windows, like those on the second floor or higher, each cost $3 to $5 extra, because they typically require more labor and more equipment to reach. And washing a hard-to-reach window poses an added safety risk to the pro, who may need to climb on a ladder or lift to reach it.
Skylights might end up being even more expensive than second-floor windows, depending on the professional and what type of safety equipment they use during the cleaning.
Window Type
The type of windows that need cleaning determine the cost as well. Different types of windows necessitate specific cleaning styles, with differing amounts of required labor.
Some windows will cost more to clean than others. As mentioned, prices can vary by the number of panes and whether they have components, like trim, to detail. A single-pane window will cost much less to clean than a multi-pane bay window, for example, and a double-hung window with two sashes and internal components will take more time to clean and will be more expensive than a non-moving transom or picture window.
The most common type window is the sliding double-pane window, sometimes called a double hung window, which typically costs about $10+ to clean. Other common window cleaning costs by type are listed below.
Dirtiness
It should come as no surprise that the amount of buildup on your windows will affect the final cost. Dirt and grime not only restrict incoming light and damage the glass, but they also make for difficult window cleaning jobs. Extremely dirty windows may even require second or even third passes, increasing the overall cost in terms of cleaning materials and labor.
