I have a joist that sits over a wall in my basement. Basically, it separates the shop area from the garage and is a load bearing wall between the kitchen and the other side of the house. The builder (in 1982), notched the joists too much, which I will be tackling this weekend. The other issue I am running into though is the way that they routed an HVAC duct. They ended up cutting probably 5" notch out of the joist over this wall and it is probably 5" long. It has caused that entire joist to split. The notch is about 1.5 feet from the edge of the joist, which spans 12 feet.
The floor surprisingly does not sag much, but I’d like to fix this so I have no further issues considering I’d like to be in this house a long time.
- Cut a joist to match the current one (I would round the notch, not make square cuts) and sister the joist.
- Install steel plate
Which solution would you recommend and if the recommendation is steel plate, can someone direct me to a document that discusses basic steel plate installation instructions. Would I need the steel to span the entire length of the joist?
Any help greatly appreciated! Adding pictures soon.
