Particle board subfloors
I have a 37 year old house that unfortunately was built with particle board subfloor. I want to put in nice, pre-finished, hardwood flooring but have learned that it is strongly recommended not to nail it to particle board. It seems that the usual solution is to over lay it with plywood subfloor, but this will cause a problem in our kitchen since it will raise the stove and dishwasher height too high, depending on the thickness. My carpenter said that pulling up the particle board would be a nightmare (i.e. very costly), and we wouldn't be able to remove the subfloor under the interior framing. Additionally, the floor creeks badly in places, presumably where the subfloor is loose/warped. I'd appreciate any ideas on how to handle this quagmire.
