Chipboard floor repair

[LEH]

I'm going to replace the chipboards on my landing as they are a complete mess after being taken up twice and a bodge repair by the previous owner.

As you can see in the photo below, there's a piece of 22mm stuck in there when the rest seems to be 18mm around it (400mm centres on the joists running left to right of the picture.

To the right next to the wall you can see there's a bit of water damage to that board that runs under the wall and into the next room. Can I do anything about this without touching the wall? I suppose you could cut right up to the wall and put a thin piece in - but is it recommended to have thin pieces like that?

Why not replace the lot with a bit of 18mm external ply?

that.

I know... but if you were going to do it with chipboard, what would you do?

 

[LEH]

From some more research it seems that you can go down to 150mm strips and the gap to the right is 200mm so I suppose a strip of that width would do it with noggins along the edge.

why would anyone in his right mind fit chipboard in his own house?

Builders fit it because
- it's cheap
- they don't have to live there
- it's cheap
- it will usually stay uncracked until the cheque clears
- it's cheap

I would rather tear pallets apart and use that wood as floorboards, than try and get chipboard to fit in there successfully.

I see the Chipboard Haters of Britain Society are out in force again

In our world today, some people no longer ask whether a thing is good, reliable, or will last long enough to make it worth having, or if it meets the buyer's needs. Only if it is cheap and is convenient for the vendor,

Yes, but as life chairman of the CHS of B you would say that, wouldn't you. What's your position on the horseless carraige vs. the horse and buggy, BTW?

 

[JohnD]

I have never driven a buggy.

I have however, ripped up more than enough cracked and sagging chipboard.

As I type this, I have a bathroom with a beautiful hardwood-faced ply floor waiting to be screwed down once I've lagged the pipes, and another room where a bed is standing on a ply offcut after a leg punched through the chipboard.

You think I do it for fun?

I don't think you know what fun is.

It's all going to depend on the joist positions and you're competence LEH. If you wish to use chipboard, then that's you're choice, but I'd go for the 22mm if you can. 18mm would have been okay when laid as one piece, but you're going to want a bit more strength now. We're not sure where the joists are, but can you get some noggins in place under the wall to support. This'd allow you to cut the existing chipboard by the skirting board, and then lay the new chipboard on the noggins, as well as the joists. You'll also want some noggins where the chipboard joins to the other rooms, to provide extra support as you go in and out of the rooms.
