I siftwash that kind of thing, around £500-£1000 depending how dirty it is (can’t tell from pics)
Problem is - Softwashing is not always remove the staining - it will if its algae - if its dirt then follow splash - wfp 1/2 day

Interestingly Darran, I do a large energy companies head offices, it’s that type of siding but white, it comes up brilliantly with hypo, even traffic film comes off…
To be honest, I hate hard work now, so there’s no way I’m WFP’ing it, especially if it’s covered in baked in bird muck
