Incorrectly oriented chipboards on the floor

[Tobbe.A]

It is time for the carpenter to complete our storage shed that the previous owner started working on. Today, it is a 20 sqm shell, built on pillars, with chipboard on the floor. Now to the question... on the boards, it clearly states "This side down," so they are upside down. Those who laid them either couldn't read or simply proceeded according to "fast and wrong."

When we took in a quote, I asked the carpenter about it and got the explanation that the tongue between the boards could, in the worst case, crack, but that this is not something he has experienced before. This is something we obviously do not want to happen. The carpenter also said, of course, they can fix it, but it feels like an unnecessary expense.

Is there anyone here who shares the carpenter's opinion, or should we ask the carpenter to remove the boards and lay new ones the right way? What would it reasonably cost in that case?

Are the boards in place since the previous owner and intact today, or is it a started process to lay out the boards that hasn't been completed?

It's primarily for the sake of assembly that floor chipboard has an asymmetrical tongue and groove,
(The upper end is longer, so the lower one slides in more easily compared to if you do it the other way around, then you need to lay down the whole board and slide it in straight.)

So if everything is in place and nothing is broken, I agree with the carpenter that it seems completely unnecessary to incur the cost just to avoid having the text on the topside.

I would definitely not change anything if everyone, or almost everyone, is in place.
If there was a single floor chip installed, I could consider redoing it ...

If there is any risk ... well, who knows, but I think it could even work reasonably well with chipboards without tongue and groove, i.e., completely straight edges, if you're going to have a reasonably stable surface layer afterward.

Remembered an old thread about this, and according to it, the strength is not affected but there might be issues depending on the surface finish you have in mind;

Perfect! I searched the forum before I wrote the post, without finding anything.

Everything is in place except for half of the last row.

Part of it will become a bedroom, and the plan is to have some form of laminate there. In the storage area, I'm not quite sure yet.

It is primarily for assembly purposes that flooring particleboard has an asymmetrical tongue and groove,

The carpenter will review the entire construction. The roof beams are undersized, and the fastening is insufficient. I have even been able to wiggle the wall studs, so they are not completely secure. I initially intended to fix it myself, but I realized it's better for someone with more knowledge and time to redo it properly. It will be nice to have it fixed, feels like a shoddy job.

The people we bought from didn't even have thumbs in the middle of their hands, so it is a carpenter who did the work. Black, of course, so there's not a piece of paper on it anywhere.

Sometimes they are made so that they don’t fully join together on the underside, to ensure a tight seam on the top side. That might be a problem if you want to use vinyl flooring. In my world, the text mainly serves the purpose of ensuring you have the right side up when sawing, etc., and to prevent laying down a panel the wrong way in the glue strings on the joists. Not very fun to flip it and mess around with glue.

I saw now that this was roughly what was mentioned in the link.
