Not all Julliet balcony "rails" are glass. Some are very close to the windows/French door. It seems many (most?) window cleaners do not climb ladders these days, so they are not able to clean between the window and balcony. Windows can be sliding ones, as well as opening inwards.
I don't envy anyone trying to clean them. I hadn't even thought about them until I moved. The retirement flats I have moved into have them on the first-floor flats. I know many have issues with them and find them challenging.
Labour Brings in excellent Renter's Rights - long overdue.
