I was wondering that only this week too- I do a few where the insides are mouldy and as said above I keep thinking they will cancel next time coz they obviously don't care about clean windows- but no- still going strong. Another of my jobs the insides of the windows are caked in a yellow/orange nicotene gunk from the amount she smokes- the net curtains are also stained the same colour- go figure.
I also have a few custies where all the double glazing seals have gone completely and misted up so that they still can't see out of the windows even when cleaned- I really can't see the point myself but if they want to keep paying me then who am I to question it?
