They look very small properties, from the picture the porches make the gutter runs look no more than a few feet each and each property doesnt appear as if it would take a huge amount of time. Id say if you were asked for a one off price to do the lot, as it looks from the picture allow 2 bungalows an hour and that'd be easily achieved Id have thought £680.00 (£20.00 each which equates to £40.00 an hour)
Pull ur finger out you'd do it in a day.
Were you allowed to go on site to price it up or did you have to do it from an aerial photograph
You do realise it isnt normal pricing this way
