I want to remove a larder/pantry wall in the kitchen which I will get a builder to do, the wall in question is a none supporting wall I have lifted the floor boards and the top of the wall is there in the kitchen, but at one end of this wall there is a 3x2 joist fixed in the wall, this 3x2 joist is holding up the stairs floorwell on the winder. Above this 3x2 joist there is an actual floor joist so is ethical for me to use metal joist straps between the floor joist and the 3x2 joist that is supporting the stairswell so when I remove the pantry wall the stairwell don't collaspe , cheers
