Q. How Do I Repair a Cut Joist in the Attic?

Q. Need some help. My niece recently had a home inspection done to sell her home. The inspector noticed that one floor joist which lined directly up with the plumbing stack had been cut from day one over forty years ago. She bought the house last year and is now moving. The joist was spliced with a overlapping piece and nailed on to the side of the cut joist and not with much overlap, about 18″ on each side. The inspector said it should be fixed before she can sell the house.

The cut was about 1/4 to 1/3 from the end which sits on the sill plate of the basement.

Does a new joist need to be placed along side the cut one and bolted or should a telepost be added or is there some kind of steel brace that can be added to support the cut joist. Looking for some options.

They make steel plates for that exact purpose. (Simpson Strong Tie).

Practically speaking, since it was only one joist, and since there have not been any problems related to this in over forty years, I think it’s safe to say her house isn’t going to fall down over it.

If her municipality is requiring it to be fixed in order to sell it, a properly dimensioned steel plate is the right way to go.
