I will be putting down hardwood floors (3/4" unfinished oak) in my kitchen. At one spot in particular that is about 3'x9' I have two crowned joists that create a hump in the subfloor about 1/4" high at the highest. I will be laying the flooring perpendicular to the worst part of the hump so the subfloor needs to be level.
Would you take a belt sander to the floor and reduce the OSB to 1/2" total thickness (where the worst spot is, slightly less elsewhere)? Will the hardwood floors add enough rigidity and support to make up for the lost 1/4"?
OR
Would you cut out the subfloor and plane down the offending joists?
I am set up and know how to do either but think the belt sander to subfloor option is easiest. But perhaps not the wisest!
