Hello,

After the carpenter laid the floor (12 sqm) on top of the underfloor heating, the boards have separated at some of the short sides (7) and some long seams (2). Is it normal for the laminate to "shrink" after it was inside the house for 4 weeks before the carpenter laid it?

I pointed out that I thought the floor (old wooden floor from 1942) was not level, but the carpenter considered it okay when the long level was used.

If this is the wrong forum, feel free to move it to the right one, but it was the best forum in my head.

No, you should file a complaint about the carpenter's work.
 
Pointed out that the job is not correct and got the response that they will check when they are back from vacation but unfortunately no answer yet even though a new text was sent two weeks later.

Contacted the consumer advisor for input but they will call back as they were not on site. The issue is that if they had ensured the surface was flat, which I pointed out when they were checking what I wanted done, they believed it didn't need to be adjusted. I believe this unevenness is the cause of the gaps as they are only where it is not flat, i.e. the open area in the room.
 
Has a kitchen been installed on the floor that locks the floorboards so that the floating floor cannot move, with cabinets, kitchen island, etc., or other heavy furniture?
I have personally managed to tear apart a short-side joint because heavy bookshelves stood on the floor and locked all movements near the wall.
 
If that is the case, they would not have laid flooring under the cabinets, which they did. Went to the store and looked at the flooring and it said that it was a u-fog and not "click," so the floor might have been laid differently, which the person who did the job should know how to do.
 
You did not answer the question about what was placed on the floor, you just wrote "if that's the case".
Now, I don't know what U-fog is, but what is not glued is generally called "click-lock".
We also don't know how the work was ordered and agreed upon, so write and tell more about how the work was ordered.

It might be good to mention what type of floor it is or even better, link to it.
 
Hen? Don't you know if it was a she or he?

No! But it's a bit strange to write like that.

It is a kitchen framework that has been placed on the floor.

And since it said u-fog on the package, it is not a click floor, but reading on the website, it is a click floor. I need to check again on site as I don't think the information is correct.
 
So I checked and physically felt with my hands, and it's a click floor. According to you, this shouldn't be under the cabinets that stand on pegs and "kick guards" because the weight of everything when it's filled prevents the floor from moving. Then it should be easy to just click them back together again. It's not like all the joints have separated (4mm), just 5 short joints and 2 long joints.
 
If it has come apart, the "click system" might be broken, resulting in material in the joints that prevents them from coming together again. So there is a high risk that you will need to pick up the floorboards to fix it. And if it has come apart by 4mm, which is significant, I believe it's due to both lateral forces and unevenness in the floor causing vertical bending. But for you to proceed, an expert should look at the floor on site to see how it is done and the conditions. If the wall cabinets fully stand on the floor with feet/socket, it becomes more sensitive than if the cabinets are hung on the wall with only feet at the front edge as support. And combined with an older subfloor, which is usually uneven, there may be some bending.
