Near to my some of work there is planning to build about 250 houses. There has been other building of small estates in recent years. Now what percentage of these new houses will want their windows cleaned, let's say 50%, so that's 125 new work. Now, this is all very obvious, but what occurred to me the other day is that years ago, in the sixties and seventies, a lot of older type of houses were demolished to make way for the new ones, which meant not many more new customers were being created. So window cleaning is definitely a good opportunity for anyone today.
