Was cleaning a house today, to be told that customers are moving down the road soon. They've bought a house and would like me to provide window cleaning solutions at the new property (still with me?). As it happens, I clean the property next door to the new house and am aware that the house is bring let prior to purchase going through. The current tenants employ a different window cleaner at the moment, but I was wondering what the form is? Should it be my job as the new owners have asked me to do it? Or the current windie, as he's cleaned there for years? Who really cares?
