I need to see the job to give a sure estimate for the customer.  When more ladder work or pole work is involved, more obstacles and things are in my way, and more bugs and dirt are there because of not being cleaned for years, prices will be higher. But some general price estimates are given below.

Residential: The average double hung window, with 2 panes of glass and a full screen, will cost 10.00-12.00 to clean the inside and outside glass, clean the screen, and clean the tracks and sills.

Business:  Prices roughly start at the low end of $1.00-2.00 per small pane of glass, per side, and go up depending on size of glass and other factors.
