What is going on with this plywood ledge and brick sill?
Long story short i bought a house to sell mine. We knew there is issues but this one has me confused on how to ask it to be fixed. Masonry crawlspace foundation with normal flooring above. Here is where im lost, they built the wall of the house 3-4 inches back leaving plywood flooring on outside. They did flash with aluminum exterior wall over 4 in plywood and down. Then there is a airgap and brick sitting on not well done 4inch block. It appears the brick originally created some sort of sill to house but flashing is great shape and no evidence the brick ever attached to house. What is going on and how do i get that gap on outside floor to edge of rim joist to look correct?
