subfloor thickness for hardwood floor

KarensebJanuary 22, 2014

We are having a white oak site finished floor installed in a previously carpeted upstairs room where we would like to put a pool table. We have discovered the sub floor has particleboard over a 5/8 inch plywood sub floor. The floor joists are 2by10 16 inch OC. We would like a solid floor and the installer suggested waiting till the particle board comes up before deciding if the plywood is good enough for the installation. I hate to increase the height of the floor by adding a half inch of plywood on top, but wonder if we should just go ahead and do it even if the sub floor seems okay. Or will the 5/8 inch sub floor be good enough?

I have seen many a successful solid hardwood floor installed over decent 5/8" plywood. Your installer is right in saying that the plywood needs to be assessed to see if it is a suitable substrate. If it is suitable, then just make sure it is 'firmly' attached to the joists. The firm attachment of the plywood and the properly fastened solid hardwood will give you a strong floor system.

What distance do the 2" X 10" joists span?
