How would you raise this wall 1/4 to 1/2 inch?
Hello, doing a bathroom remodel and have hit a snag. I'm trying to figure out the best way to raise this wall about 1/4 to 1/2 inch to remove the rotten board and replace with two 2x6 ripped to size?

Anyone have any ideas?

to raise the wall, step one, remove all the plaster, for it will surely crack.

try this instead... put up a temporary wall a foot or so back to support everything. use a Sawzall with demo blade to cut along the rotten footer on both sides. pound it out. pound in a new board. nail in place. fix the wall on the other side, light plastering.

there is no law that says you have to replace that plate in one piece, so things are way easier and you maintain support if you replace 2 or 3 foot pieces, alternately, and leave enough of the old stuff in place to keep your gap open.

thanks, problem with the temporary wall is that the wall in the picture used to be an exterior wall, now its interior. the temp wall would be holding up a tin roof and that's it.

any other ideas? I was thinking about nailing a 2x4 into the pieces above the rotten one and using a 6 ton floor jack? I need just a little bit of lift ensure the piece i'm putting in is actually supporting something and not allowing it to settle more, even if only slightly.

You really don't need to lift it at all, just keep it from dropping while you make the fix. Nailing in a 2x4 to jack against will not work - it will only tear the 2x4 off.

Several ways to support the wall, including swschrad's idea of a temp wall. As long as the temp wall is supporting whatever load is on the existing damaged wall, it will work. You can also cut a piece of 3/4" plywood to fit tightly over the wall and securely crew it to each stud. Then add a 2x2 on each corner and screw it into both the plywood and the adjoining wall stud off each corner. This will hold the entire wall in place - no way it going to bend 48" of plywood.

Once you support the wall, cut out the bad stuff with a sawzall and replace. If necessary, ensure tightness by adding some shims underneath or between the new bottom plates.

Will throw that option around as well, thanks.
