Morning folks.I offer a pressure washing service to go alongside my main job of window cleaning.I get fairly regular driveways/patios etc that are easy to quote for but one of my customers has asked me to quote for an area of just over 500m2.All paving and brickwork.Can anybody offer any advice on pricing for an area that size?Its in the Sevenoaks area.NW kent.Its by far the biggest area I’ve been asked to quote for and I want to get it right.Its a fine line of charging too much to put the customer off and not enough so it turns into a pain in the bum.I was reading that some people charge £2 per square metre cleaned,is that still about right?Many thanks in advance.Craig
