I have owned my mobile home for a couple of years now. It was a repo from a bank so the previous owners really did a number on it. I have fixed a majoriy of the damage they did to it and now starting to find other problems. I am trying to make it a little more energy efficient during the winter and summer months by adjusting stuff under the house. i sealed the point where they joined the house together. also during the winter i shut and insulated around the vents. i even foamed around the foundation. i closed off the access to the uninsulated porch under the house. all this has seemed to help with energy usage. now i have noticed that the mold smell and the moisture under the end of the house with the has increased. i have also noticed that the room and bathroom on that end of the house had been extremely colder then the rest of the house. i am working on putting better insulation around the crawl space door but don't know what else to do with the moisture and cold air. any thoughts would be apreciated.
