I priced a dormer bungalow yesterday which had 2 Skylite windows on each side of the apex, very large conservatory, 2 sets of patio doors, and 8 windows which included 2 above the conservatory in a recess and very difficult to get to. I quoted £45 as a one off clean and the customer said you are joking, the last one only wanted £7. I told him to snap his hand off.
