Man, I know the type. I usually try not to get involded with people like that but i guess if the HO is a friend and he's makeing things miserable for you then let hom have it. By the way, your right the house will leak without some type of WRB.
I am installing a wood floor for a home owner. This is new construction. The home owner hired me not the contractor. He has been on my but the whole time. I am about sick of it. He thinks he knows every thing. I have grown up in constuction with my Dad. I am about to inform the home owner about some of his work, but I want to get my facts straight first. We are in Southern Illinois were the winters are cold. The summer is very high humidity. The house is on a hill in the middle of a field in the country with constant winds. This contractor has not put any Tyvek on the house. He said it did not need it. The sideing is put staight on the OSB. No tar papper or wrap. Is this crazy or am I? Oh and the home owner & I are now friends.
