Levelling T&G subfloor to receive semi-solid wood floor

Hi,

Our builders are completing an extension to our kitchen. The old kitchen floor is T&G wood and the extension is concrete (about 5mm higher than the T&G flooring). Also the T&G floor is not level in itself, but seems to have some bumps and dips.

We would appreciate any suggestions as to how to level the whole thing off
- so far the suggestions have been 1/4 inch ply on the T&G - will this level off the old floor enough or do the individual lumps and bumps need to be addressed
- is it possible to shave the 5mm off the concrete floor?
- is there a levelling compound for the T&G flooring - the boards are quite tight (ie. no gaps really between them).

All suggestions are much appreciated as we are at our wits end and no-one seems to know what to do!

Thanks

The traditional fix for leveliing timber floors is to fix 3 or 4mm hardboard using lost head panel pins (usually copper plated). This will even out any high/ low spots and provide an excellent base for any subsequent floor finish, carpet of timber. The ply should be dampened before fixing. Ply would be a waste of money for this exercise (hardboard would be at least half the cost). I'm surprised your builder didn't suggest this option..
 
i wouldnt put hardboard in a kitchen . if any damp / spills / leaks got into it, it would disintegrate and possibly stink too and you'd have to take up the entire floor. plywood seems a safer option.

Oops, I'm so sorry, I replied to that thread late last night (after another busy weekend with the children:) ) and completely missed the reference to "kitchen floor". As you rightly suggest ply would be a far better solution- 6mm WBP grade, well screwed down. Hardboard would be perfectly acceptable for any non wet areas, especially as an underlay for carpet or vinyl. WBP makes a good background for tiling. Mea culpa
 
Many thanks for taking the time to reply and reduce our headaches considerably! Will suggest this to the builders.
