We just purchased two houses that are on one property. The house that we are currently living in(one of the two purchased) has the foundation under the bedroom, which only has a crawl space, bowing or moving out from under the sill. We have lived in this house three years now and first noticed it last summer and this summer it got worse. One thing that I have noticed is that it tends to "pull" back in in the winter (when the ground freezes). Is there an "easy, quick" fix, or is it more complicated. We live in SW Minnesota and have a frost line at about 48 inches, give or take"
