I have been contacted for an estimate to install about 300 face ft of wall stone(manufactured concrete) in a rear yard. The issue I have is one of access problems one side of the house is about 5 ft from the much hated neighbors property ,Thus no access there...the other side an A/C unit blocking the way, I specified in the proposal that moving the A/C unit was the property owners respnsibility, but in retrospect I think maybe I should have handled it for them(subbed out to a qualified contractor of course). I really don't want any scheduling problems as it will all need to be co-ordinated on a tight schedule due to materials delivery. So the question is..what would you have done????
