The biggest mistake I ever made in this game was underpricing cons.
when trad, they are easier as you can do most of them without ladders.
When you go WFP, they are no easier than doing the tops
As said above you have to charge more for the ones with full length panes, two panes are the same as a patio door.
Cons with dwarf walls, I charge as two panes equals one window.
We need to think about charging tree tax too. Trees are often overlooked when pricing, but overhanging trees can mean taking twice the cleaning time, especially in the summer.
Roofs take a lot longer, they present a greater target area for birds, and not being vertical can take much longer rinsing.
