Noisy floors in new build

[bobiscuit]

We have been lucky with our new build, only really minor snags and the builder has been mostly helpful... But this is an issue we can't resolve.

Our upstairs hall (and to a lesser extent the bedrooms) are excessively noisy. The house is around 2 years old, but it has been like this since 6 months old.
They crack/creak/squeak really badly when walked over.
Some spots you can constantly make noise by shifting your weight from left foot to right foot - but other areas make a loud noise once, and then only "reset" when you walk over to the other end of the hall and back again.

I have very limited knowledge about these things... But the builder's explanation was something about new-builds having floors glued down, and because the heating pipes run under the floor in the hall the glue dries out.
They attempted to fix this last year by lifting the carpet and screwing in about a million screws (that's what it sounded like... They were at it for 3 hours, and it's not a big hall). It made literally no difference, not even 1% better.

I know that the house got built during an especially wet winter (even by Scottish standards) - could that have warped something?

I'm not sure what to do at this point. I'm reluctant to let them pull the carpet up constantly in case they wreck it.

Advice?

Are they actual floor boards or the chipboard sheets? As they are saying it was glued I suspect the latter. I had one section that was really squeaky and I had to pull it up and relay it gluing it to the joist and together and a load of screws which seems to have resolved it for me.

Not sure what they are, unfortunately.

I thought they had to be cut out? Is it possible to pull them up and re-glue?

It depends where your joints are and if you can start at an edge.

On my ones I was lucky that the room wasn't in a finished state but if I tried to do my hall now then it would have to be cut and then relaid.

They weren't glued properly in the first place. The glue stops the chipboards moving in the tongue and groove, which is causing the squeaks.

Unless someone knows of a better idea, your only option is to rip the chipboards up and lay proper timber floorboards. This is not a difficult task.
