We have a 1950s house with an addition built on cement block over a crawl space. We've had the house two years. The room is carpeted, and we cannot find any access to the crawl space. We've looked in the closet, room corners, and all around the outside. We need to access the space to repair the H/AC ducts, and to insulate the space. The floor joists are on 16 inch centers.
How can we create an access so we can do the work? Can we cut a floor joist? Thanks.
