Counting window panes for a window washing quote

After you check out how we count window panes, get a quote for window washing instantly:

Notes in addition to the diagrams below:

Cleaning storm windows: Glass storm windows (not screens) count as 3 panes (1 to remove the storm window, 1 to wash it, and 1 to re-install it).

So a double-hung window with a storm window would count as 5 panes of glass:

2 panes for the double hung window itself (see below) + 3 panes for the storm window = 5 panes.

Cleaning removable grids: If you have removable grids on your windows, do not worry — those individual squares do not count as one individual pane. We remove the grids and re-install them and it counts as only 1 pane.
