Panes are the unit, not windows
Time on glass comes from edges and separate pieces, not from square footage. One large fixed sheet gets washed, pulled in a few strokes, and detailed around four edges. A six-over-six sash is twelve separate pieces of glass, each one washed, each one pulled, each with four edges finished by hand. A modest older house near the center of Omaha can price above a much larger new build with half the labor in it.
So when a quote is written per window, ask what a window means in it. A slider with two sashes is two panes. A bay is three units in one opening. A tall stairwell run may be one enormous piece of glass that is fast to wash and slow to reach. Counting openings and counting panes give very different answers on the same house.
