While inspecting rot to the band joist under the front door, I noticed a 1/2 gap between the sill plate and concrete block foundation on the one side wall. The other walls look normal in that the sill plate actually sits on the foundation. So, from the basement I felt all along the top of the 2 X 6 sill plate under the fiberglass insulation the entire length of the foundation. Found no anchor bolts. Thats not going to look good to the inspector should I ever try to sell this pig. Any ideas on what I should do, if anything? Had the house built in 1987.
