Job is part of a large exterior clean - the driveway is tarmac but its not a clean finsh - looks like it wasn't properly compressed when it was laid and there is green algae growing amoungst the small gaps in the tarmac - i pressure washed a test area and it was difficult to get the green stuff up and left a decent sized holes in the tarmac, also there was a lot of debri blasted off onto the wall. I have some pics which i will post later but wasn't sure if this kind of job is worth just saying no to ?
