We have a permanent wood foundation (approximately 12 yrs old.) We have had no problems until this week. I noticed our paint in a corner of our basement was bubbled and the carpet was damp. We have had a lot of rain lately. Could this be something small (blocked footer tile) or does this automatically mean we have a major problem on our hands. If it is a major problem, what all would it entail to replace our basement? It is only one small corner of the basement and this is the first we've noticed anything going on.
