There are several factors that influence the price for Window Cleaning.
The first and foremost is the Qty of Windows
This is followed by the size of the windows. Some houses have floor to ceiling glass panels whereas some only have normal waist-high windows.
Access to the windows is another factor, i.e. if we need to move couches or other furniture to access the window.
Another critical factor is whether there are MOLD present on the window (or the window frame). (Mold result in sticky window panes which takes more than double the time to clean the same window without mold, as we need to use a harsher chemicals as well as other tools to get the mold off. In severe cases we might ned to pre-treat the windows with a mold product and return later to clean it off.
Cost for windows vary between $2 to $6 per window (average)
