The flats go up to three storeys high.
I think the only safe way they can be cleaned is using traditional methods, accessing them through the flats themselves which would obviously be be problematic, although not impossible.
What if I offered to wfp all the other windows on a Friday and then be there over the following Saturday and Sunday to do the balconies when people are more likely to be at home?
There are 96 balconies, I would obviously miss some if people were away for the weekend but could probably do most of them.
Anyone think they might go for that?
