If cleaning of ladder using wet soapy clothes to wash and scrim to shine, I price by ladder moves, usually clean 5ft safely without over extending.
So if just Soffits and Fascia, I would charge 100ft/5ft x £3 = £60
If soffits, fascia, exterior gutters then it would be as above but £4.50 per climb = £90
Remember though I'm in Scotland, if your further South than me but more north than the southerners, then you may get more than me, but less than the southerners
