Been asked to clean a 4 bed (3 bed conversion) fascia's only and not the soffit's and was wondering how to price it, the facia's are wooden not UPVC. Also what's a good chemical to use on them, i'd imagine good old soap and water but is there anything specific on the market I can use ? I was thinking of a one off price rather than an hourly rate as I'd imagined 2 hours and a price of £45 does sound about right ?
