I don't think there is much excitement involved.
[i]We went up to the top floor and then my mate climbed out of the window, stood on the sill and closed the window after him
He cleaned the outside using a swab and squeegee, then opened the window and climbed back in and did the inside.
Then he said to me: "You do the next one"[/i]
You ever tried this? 
Call that exciting?
When I was in outdoor advertising (not long packed up after 30 years) I would run a triple 18 foot ladder from the street up to a three plank staging on the side of a cinema, climb up it carrying the bills and paste bucket. Then proceed to set up a ladder on the staging that was left up there in all weathers (nice and rickety) to post a twenty foot by ten poster.
No H&S then .
It was always windy up there.
