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 construction 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 Tyke on the house. He said it did not need it. The siding is put straight on the OSB. No tar pappier or wrap. Is this crazy or am I? Oh and the home owner & I are now friends.
