My family and I bought our 1st house this spring and have had major water problems ever since. The water problems have recently been fixed by a reputable contractor and is warrantied for life for a small yearly fee. Now I am focusing on redoing the finished basement. The walls were put together in every wrong way by the previous owner and need to be replaced. When I replace these should I install a plastic vapor barrier between the foundation walls and the studs, if so what? Or will this cause problems trapping potential moisture on the foundation walls and leading to mold? Also should I install any insulation, if so what? Rigid insulation was removed from the outside of the walls during repairs (it was not replaced the foundation was sealed with mason's tar) there was none on the inside. We live in Wisconsin and I would anticipate heat loss in the winter but don't know yet.
