Older stonework and careful methods
The city centre is built in the sandstone Tyneside Classical style, and the surrounding suburbs mix Victorian and Edwardian terraces with later semis and newer estates. Older masonry and roofs are the reason soft washing is on our list at all: dilute biocides applied at low pressure lift algae and staining without driving water hard into joints or surfaces that were never designed for it.
Tall terraces in places like Jesmond and Heaton often have gutters two or three floors up with no easy access at the back. Vacuum poles reach standard two storey guttering from the pavement and most awkward runs over extensions, and a pole camera shows you what is up there without anyone climbing onto a bay roof.
