Using extreme poles that's never 5 man days, ye it may be a pain with runs but u would just run along 1 row of glass cleaning all the frame below an then back again doing the same, u would have to wash all the frames with this job anyway. If required just hit sections were needed.
I to would get the pic down, I have posted pics of jobs on here an all of a sudden the contracts manager has said to me, we r getting bombarded with calls regarding the window cleaning ......
If u have the man power u could batter it, say u an 3 guys would do it in 2 days price it at cost plus £1000.
but if ur on ya own I would go around £1500 - £1800 that be a decent pay check for a weeks work an worse case u run into sat morn, still good money.
On the big section I would run 2 poles, first one just ahead of the second but a floor higher, and just run from end to end, after the top row the higher of the 2 poles is just giving it a second blast which will help with runs
