I have installed hardwood floor in my livingroom. I have a 3/4" plywood subfloor underneath but I realize now I did not install the hardwood perpendicular to my floor joises.
My room is about 22 x 13'.
Is there something I should do? Should I get underneath the floor and reinforce it?
The Wood Flooring Manufacturers Association (NOFMA) recommends that when 3/4" solid hardwood flooring is installed parallel to the joists, that the joists have blocking installed installed at a maximum spacing of every 24 inches between all joists under the hardwood system IF the subfloor is properly-installed plywood and below a thickness of one and one-eighth inches OR if the subflooring is properly-installed Oriented Strand Board (OSB) and is below a thickness of one and one-quarter inches.
If the properly-installed subfloor panels is at or above the above thickness(es), then no blocking is required).
Particle board is not a suitable subfloor material for nail down hardwood flooring.
