Hi
In certain areas of the house the house has an old funky smell. Do I need a vapor barrier ? I think I may have a cracked main sewer pipe that may have leaked into the house. Not sure though. When it is hot I smell septic. The plumber is coming this week. Also how much insulation is needed in the attic? Is there a certain depth that I need? I guess I will have to get up there and crawl around to see what is there. But I really dont know what I am looking for. Maybe I need new insulation. I am tired of trying to figure it out. Should have bought a new home.
