I am only able to see one picture and it won’t allow me to zoom in at all, but from the wide image it appears that there might be a slight haze on the glass from the cement above dripping down. You may need to do more scrubbing than a basic window cleaning, which means you would charge more.
What area are you in? Some regions are able to charge more per pane for commercial than others. I think Luke charges $3-$4 per pane for his normal commercial work, my area I can only do $1-1.50 per pane per side.
Also need to know if this is going to be WFP or Traditional cleaning to give an accurate opinion.
Otherwise, whether it is a Doctor’s office or a strip mall or restaurant, all of my ground level commercial work is the same price per pane.
