I've been asked to put in a quote for 36 flats that are in 3 seperate blocks all on the same site. All to be cleaned once every calendar month. Every block is 3 storey. They put out all services like grass cutting, internal cleaning and window cleaning out for tender every 3 years approx. I went and met the director earlier and have a price in my head. The windows to be fair were in a good state and hats off to the present windy. The deal breaker may be that the present cleaner won't clean the cladding around the roof line. They have asked me to quote that too, which I also have a price in mind. My question is this; does anyone here clean these type of properties, how much do you charge and how long does it take you to clean the windows. Below is a picture of the type of flat. In the pic there are 9 flats fronts only.
