My neighbour and I (In Gabriel Street) have just had a guy at the door fitting the exact description. About 40, addidas track suit top and bottoms quite a confident and chatty 'geezer'. He gave me the whole spiel about his cleaning company doing the whole road and did we want ours done. Because I have already read this thread I told him that the whole road has used a trusted window cleaner regularly for years and he is completely wasting his time by calling along here. He then said that someone from the street had actually hired him but he could not remember which house. He then rushed up the road chatting nervously on his phone and did not call at any other properties. If I see him again in the area I might call the police, he is clearly a scammer.
