I reckon that anyone who may be considering setting up abroad would need to take a trip to their intended location, and spend some time 'canvassing' as if they were actually starting up, to gauge whether there is a demand for window cleaning.
I relocated to Ireland last year due to family circumstances. I left behind a very steady and well established window cleaning business and started again from scratch.
I am 9 months into building my business here, and have found the attitude towards window cleaning completely different here.
In Britain, most people were very pleased to see me every month. Here, although I do have some good regular customers, I have others who may only want their windows cleaned once a year!
