I'm not going to mention what firm it was in East Sussex that quoted a job I do but I was asked to clean down all the most awkward facias and soffits you've ever seen on a house I've done the Windows on for years,they are turret shaped that are back to front so they are up and underneath the gutters. I looked round it and as it was 3ish stories it was a scaffold job really due to not being able to get any pressure with the brush,it was a 2 man easy 800 job, another firm sent a bloke round 1 Saturday with a fibreglass 30ft pole and sill brush it took him 10 hours and the firm got 200 poxy quid for it,not the bloke who attempted cleaning it overall lol. Even she took the p in her posh way after all that they tried to get the Windows off of me but failed.
