Levelling a wooden floor.

[red_xl]

Hi guys, thanks for reading,

I'm starting on renovation our house now the electrics and the plumbing have been sorted out. I want to start in the dining room/living room area. However, due to some subsidence, and from years of people taking the floor up then putting back down - the floor is slightly unlevelled. Tilting both left to right, and front to back (we're not talking huge amounts, just noticeable).

I was thinking about removing the old boards, and replacing them with large sections of whatever the equivalent of MDF is these days, probably about a metre square or there abouts - whilst making sure they're all level with one another.

I'm looking to see if for some reason I can't think of, this a silly idea. Anyone ever done this, or this there an obvious reason people don't do it, that I'm missing?

Many thanks.

MDF isn't what you need here.....consider tongue and groove chipboard, 22mm thick. Available in 2' x 8' lengths that can be handled easily enough by one person.
It won't automatically level the floor though!

Use some wood fibre screeding compound like level flex

Thanks for the reply.

I was planning to raise and lower the boards as necessary until they were level (havn't quite got a perfect solution, but it involves using slivers of wood to bring it all into line.)

that could well be a labour of love doing each one individually.
As you have to take them all up anyway, why not do that first and have a look at what has caused the problem, could be a collapsed sleeper wall or rotten bearers or joist ends. It might then be easier to address the floor as a whole.
If everything seems out of level but otherwise solid then you could sister up the existing floor joists and bring the whole thing back level that way
