Dutts, I was referring to the link Darkseid gave me though. On that site they said seepage isn't a problem.
No, in all fairness, that $15k I mentioned was from the contractors who came out to see the job. It was for the entire house not just that one side. They said it made no sense doing just one side since it was not cost effective.
We'd like to do as much as we can ourselves without making bad matters worse. We enjoy working on the house. Fruits of your labour can be sweet.
