Contact the manufacturer of the wood floor that you intend to purchase and
ask their advice.

I have a situation in a 13yo townhouse (I own this one) where the first
floor has about 325 sq ft of 1/2" hardwood laminate coverage and
about 600 sq ft of carpet. Both rest directly on an OSB subfloor.

I want to replace the entire floor with 3/4" hardwood planks. This
is do-able because it will only raise the floor a net 1/4". However,
some of the contractors I've talked to insist that I need to lay
a 3/8" layer of plywood on top of the OSB before the new floor
is installed. Others say it's not important and that OSB is the
recommended subfloor for hardwood anyway.

I'd obviously like to avoid both the cost and pain of raising the floor
an additional 3/8" if I don't have to. But ... I also want this done
rights. So ... what is the wisdom of the Wreck on this one?

TIA,


P.S. There are some floor creaks, but at least one contractor told me
this was primarily an artifact of the floor joists and that adding
the additional layer of plywood would make little or no difference.
I wonder ...
