Hmmm...before I finish painting this last little corner of the house I may as well replace those two corner boards, they look water damaged at the bottom, it’ll only take 30 minutes.

And the Homeowner Gods smile.

Uh-oh, that bottom corner of the sheathing doesn’t look good either. No problem, I’ll just cut that section out and replace it, easy
-peasy.

And the Homeowner Gods begin to laugh.

F*)’#. The #*&)’ corner of the sill is rotten?!! ) go$(&)it!! Son of a b#*”($. where’d the hammer land....

And the Homeowner Gods’ laughter grows louder as they congratulate themselves and wonder at the foolish and futile optimism of yet another home owning mortal.

So, I need some advice on repairing this corner. I haven’t pulled the clapboards off the other side of the corner yet but initially it doesn’t look that bad. I’m cutting the sheathing back to solid material. I’ve dug out most of the rotten sill. The rim joist is still solid. My thought is to somehow cut the sill back a foot or so to good wood and replace it. Is that the way to go or is there a better way to do this? When I’m cutting out that corner sill do I need to worry about support?
Thanks

Use a nail claw and pull the nails that you can see.

Measure over from the wire 1 3/4 and draw a plumb line up.
Set the depth of the circular saw to 1 5/8 deep and cut the red line.

Finish the cut down with a sawsall .



Need to see around the corner.

Are you saying cut the rim joist and the sill? The joist is ok, there is a little surface softness but other than that it is ok. The sill needs to be cut back beyond the wire to between the wire and sillcock.

Drill a hole near the bottom of the rim so you can cut down thru the sill with a sawsall.

If you figure the rot is not too deep, you could remove the rotted wood from the sill plate with a chisel and/or oscillating saw. Then fit a replacement piece and glue it in with PL Premium and a couple of nails just to hold it in place until the glue dries. The trick would be getting a reasonably smooth surface on the existing sill plate, but if the rot is only an inch or so deep, should be do-able with a chisel.

Should I worry about supporting or jacking the joists up in the cellar? The cellar ceiling is open so I could get support next to the foundation wall.

not the floor plywood and the sill plate above both reach the rim around the corner. So nothing is going anywhere for that small piece.
