A Plan or Not to Level the Floor?
(Climbing the learning curve on fixing old houses)
1) Have a rim joist that sits about 1 inch above the other joists which are 16 inches O.C.
This causes a rapid drop in the floor from the wall and then it is quite level.
Appears originally built this way.
Rather than tearing up the entire subfloor , T&G old growth pine, I’m thinking of mounting a sister joist
on the Rim Joist for the entire length needed (8 feet). Then cut the T&G old floor at the joist
next to the Rim Joist and nailing in a piece of “3/ 4” plywood which would span the area from the
Sister Joist to the Joist next to the Rim Joist. OK or got a better idea?
2) Rim joist is “2 x 10” so thought a “2 x 8” or rippled “2 x 10” so that the bottom of sister levels with
the original Rim joist as a sister?
3) Planned to use 8d nails in an “M” pattern, and pre-drill to stop any splitting as the rim joist is quite old.?
Alternatively would screws – maybe DeckMate – or Ceramic Coated – or 3/8 lag bolts be better?
4) Everyone seems to be an advocate of gluing plywood to the tops of joists to stop any squeaking. Anyone have any experience trying to remove a glued plywood floor and what if any destruction of the joist it was glued to after removal (i.e. is an new joist then required)?
Any input appreciated.
