Raised subfloor and slab mix
My wife and I bought our first home in November. The original 1947 house is U shaped on a raised foundation. A family room was added in the late 50's in the middle of the U. This room is on slab. I have found termites around the perimiter of the room and I am told difficult to treat. The slab is poured right up to the footings on 3 sides. There is no structural damage from termites. Is this proper construction? Should I have the room redone so it has crawl space? Anyone know how much (approx) this would cost? The room is 19' X 18'. I like to do things right.
