wood floor on sleepers
We are replacing our wood floor in our kitchen. It appears that the original floor was installed on 2X2 sleepers that are installed onto 1X4 subfloor. We need to maintain the floor height to match an adjacent room. My question is: should we remove the sleepers and build up the subfloor with plywood or just install onto the sleepers using additional pieces where floorboards meet?
Thanks for any help or advice.

What kind of flooring are you installing?

Almost all modern flooring is designed to be installed on top of a solid, 3/4" thick subfloor. If there is no subfloor on top of the sleepers you now have, you really need to add a layer before installing your finish floor.

Removing the sleepers and building up with plywood will certainly make the floor solid and strong. It will also be expensive. Still, depending on what built-up height is actually needed, it could be a lot easier than adding new sleepers if you need to do that to adjust floor height.
