George: Help! I am desperate. I recently bought and remodeled a 1955 ranch house of about 2,000 square feet. This house has a crawl space. I replaced all the windows and the AC and did some other cosmetic changes plus gutted and replaced the kitchen. Now I have high humidity levels in my crawl space and in my house. I have spotted white mold in some of the crawl space and in a kitchen cabinet, plus there is a bad stench coming from several cabinets around the house. The humidity in the crawl space is 80% many times and in the house 55% on a good day but often around 70% or higher. This house had only 4 foundation vents and I had 8 more added about 6 weeks ago but I haven't seen a difference. I also had gutters added the other week. It is still hot in Dallas and very humid. I am hoping the levels will drop with cooler temps but I am starting to think it won't solve the problem. I have been told that I need to either have spray foam insulation put on the joist and beams under my house or have r19 bat insuation with a vapor barrier put on. The bat insulation is much cheaper. Or I have also been told I should lay a vapor barrier along the floor of the crawl space (at least I think that is what they meant). Others have said I should add a fan on the vents. Well you get the point. I just don't know what I should do and I feel like the tens of thousands of dollars I put in new floors and a kitchen is being flushed down the toilet if I don't fix this problem. How can you advise me. Right now I am leaning towards having the bat insultation added with the vapor barrier becasue I was told it would run about $1,600. This is a lot less expensive than the foam which I think would be over twice the cost. Thanks for your input. Chris
