I am currently renovating the entire second floor of my 1920's home and have run into an issue. The subflooring is currently unleveled and had intentions of pulling up the subflooring, adding a sister joist along the existing joist to relevel the floors and then laying back the original flooring. Upon pulling up some of the flooring we realized that the wall studs are resting on the flooring instead of the studs going through the flooring and being secured to the joist. Another dilemma is that the walls are off centered from the floor joist creating no support for the studs if the flooring is removed. I am currently unsure of what the next step should be or if there needs to be another route taken for this task.

  • Go through the ceiling instead.

    Are you saying that the 2nd floor walls, which probably also support the roof to some degree, are resting on floor sheet in random unsupported places, rather than on structural members? Could it be that these are "false walls" that were built later, on the inside of the original structure? Nov 20 at 5:35
  • Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking.

  • Unless this is a nonstructural wall (as mentioned above), the part of the subfloor under the wall is now part of the building structure. If you want to remove subflooring not under the wall you'll have to cut it and leave the part under the wall.

  • To ask the question from @JimmyFix-it another way: is there no bottom plate to the stud wall? If that’s the case, add one and all your issues will go away. Nov 20 at 14:03
