Most standard windows on the ground floor cost $7.50 each to clean just the outside and $10 each to clean inside and out. Specialty windows and standard windows that require extra equipment and time to reach often have an additional fee per window. 

Windows are counted by each pane, meaning the bay window below would be counted as 3 while the casement window would be counted as 1.  Using this method, there is a total of 30 windows in the "standard windows" section of the guide below.
