sub flooring

the flooring underneath the carpet is popping up. I hope I can explain this so you can visulize the problem. Down in the middle of the living room carpet, you can see where the flooring has raised up a little almost looks as if the padding to the carpet is lumped up, but it is not the padding. You can stand on it an it will slightly give. I have notice this in other areas of the house. We have a crawl space, and did have someone come out and look at the house to see if it needed jacks, we called the contractor and he did place a small jack on one of the joist,but not even near where the problem is.Any sugguestions before I start pulling up carpet?
And any suggestions as to what could be the cause.

It sounds like the subfloor was not glued to the joists when installed.

If this is a new house, then glue and fasteners are almost second nature. Who wants to come back and do something a second time, like your contractor will have to do. It also sounds as if proper support wasn't given to structural members to prevent this.
