Floors Popping under carpet when walking around

[Lewis91]

Good Morning All,

I am having a major issue with the new build house we have just bought and the builders seem to be making it worse so looking for ideas to discuss on Monday morning with the builders.

When we walk around upstairs you can hear massive popping noises below you can feel it underneath you foot but if you bounce on that area it doesn't do it again.

So far they have put wedges under the walls and screwed the boards down more but it seems to be getting worse. The floorboards are like chip boards.

Any help would be greatly appreciated.

Probably movement of the tongue and grove.
It may pass in time.
