I priced a school a few years ago 12-1400 pupils,I walked round with the caretaker-burser,all to be cleaned inside and outside once a year and outside only once a year. I got 2/3rds of the way round and said for inside and outside we are over the 2.5 k Mark they stopped me and said really,I said well yeah it’s going to take 3 of us minimum to clean it. They then said we will give you a clue the other firm was cleaning it for 1200 in and out and 800 outside only,completely pointless contemplating jobs like that if you’ve got decent domestic work years ago you’d get good money cleaning schools and massive Tesco’s etc those days are long gone people are cleaning them for peanuts.
