hi there,
well more of an opininion.
the govt hasd now bought in PPG3, where this requires new house building to increase in density and to go higher in floors. the other signifcant knock on effect is that the layout of streets, is such that properties are being built at the front of the plot, IE only a metre or so from the road.
therefore more grime on the windows more frequently from the nearer vehicles,equals more work.,
and the last things these guys want to do when they have bought their shiny new house is have to clean the windows at the weekends. So possible lucrative market place would be these new developements that are going up Literally on the kerbside.
just a thought
have a good weekend
regards
martin
