A freind asked me ideas on how he could level his floor.

My feinds kitchen is in the korner of his house, and that corner of the
house has settled...
so now the floor is unlevel

I talked to him about sheeting it with 3/4 or so sub floor. this would give
him a chance to cut a long tapering wedge for each joist.. and cap his old
floor. the existing floor is 1" wood t/g old flooring.

any ideas are appreciated.

another option is to raise each joist along the band where the foundation
has settled....?
