Our technicians will begin your service by first evaluating the locations of your windows, the methods needed to access them, and their sun exposure. After reviewing each of these they will plan where to begin and what order to proceed in. This is important to help ensure the best conditions for cleaning your windows and in the most convenient order for you. If you prefer for us to begin in a certain place, such as on the inside first, so you may leave sooner, just let us know and we will be happy to do so.
