I do this also. It doesn’t take that much time and its a good upsell, depending on how dirty they are. People that are truly concerned about it are willing to pay, usually. I had this one lady, when I was almost done, said she rather have a deep cleaning of the tracks and sills instead of the “basic cleaning”. Charged her another $100 and it only took me another hour and a half.However, I have a habit of detailing the crap out of sills and frames, so I kinda include the labor in the price. If the customer balks I explain again that I clean more than just the glass.
