Uneven floor in different spots of the house

ducker

Hi there,

i am actually going mad with some unevenness on the floor and not sure whether this is serious or not.

The unevenness is difficult to spot by eye, but if you walk on, you can feel the difference.
I won t be able to say how much uneven is the floor, but there is a little space between the floor and skirting of about 5mm

I bought the house 2 years ago and noticed "only 2" spots, one at ground floor next to the fireplace and one at the first floor almost in line where the wardrobe sits
On the party wall i have horizontal hair-lines down and upstairs which I understand to be normal movement of the grounds.
Structural engineer reported those cracks are normal and signed the paper before we bought the house.

The one on the ground floor got a little bit worst since i moved the heavy 28" CRT TV in that spot, the one on the first floor seem to stand still

After i bought and placed a desk in another room on first floor, the desk created a new unevenness where it sits (it sits in-line with the door/entrance)

Last one is the ensuite bathrooom. 2 years ago we noticed some unevenness there too, but after installing a bidet, after 2 years i now need to screw again the bidet as it seems the unevenness got worse
The ensuite is just over the kitchen and we did not see any sign of leaking so far

All the rooms have semi-solid. The bathroom has tiles

House is about 10 years old and my neighbour (the other semi-detached next to me) has no issue with unevenness, not on the ground neither in the upper floor.

I have called some carpenter and they all say that it is not a big matter and i should not be worried about too much, which gave me some piece of mind

But i want to fix this and i m not sure where to start and if a carpenter is the right person to do the job.

Any thoughts

I ll try that again.

Would it be best a carpenter/joiner or a builder to (maybe) reinforce my first floor (which is uneven at the edge/party_wall) ?

How easy and risky is to cut the floorboard under sit under the laminate(to have access to the joists) ?

Any advice is much appreciated, i am totally new for this

Ground floor screed prob isnt exactly level. Ive seen this quite alot when in working in houses and its nothing to worry about. 5mm is nothing. I was even working in a house where the upstair floor wasnt level, id say 10mm out in places or even more and it was all down to the trusses not level. I think it was something to do with the walls the trusses where sitting on being abit out but the house was signed off and sold.

As long as the foundations,walls and roof are ok then youve nothing to worry about.

Thanks a lot yoloc for the reply. It is very much appreciated.

Even if it s not something to worry about, how would you think it can be fixed?
Is it worth to fix?

Cant really say 100% because havent seen it but if its just the screed laid uneven, i would just leave it and then when yur re-doing your floor at a later date ie- wooden floor/carpet etc.. then you can fill in some of the uneveness with some self leveller though it wouldnt sort it all if its to much uneven. You could also take a jack hammer to it and take some of the bumps out but IMO thats just to much work for something like this.

Stick a level on it and take a few pics to show us how bad it is.
