I live in NE PA. My wife and I own a half double home. Our kitchen floor has sunk due to excessive moisture coming in to our basement. That problem I can handle. I would like some
advice on levelling our floor so that items on our kitchen table won't roll off the lower edge of the table anymore. The middle wall between the halves is the common wall. Many of the walls in the house are still plaster and lathe. So jacking them up from the basement floor would not be the answer. I will be supporting the floor joists with a beam that will be installed to prevent any further sinking. Any suggestions? Any advice will be greatly appreciated.
