2) All floors will face the squeak problem. No exceptions. SOme builters use nails, then screws and glues to faster sub-floors to the joists. But you guess what. After the owners move in and have been living in the house for a while (1-2 years). The areas have most frequent traffics will hear squeaks. Subfloor and the joist do move by themselves.
There is no ultimate solution to that but a re-tightening process is necesary. My bilder sent in the workers to open the laid-down carpet, and re-screw the areas I pointed out to them (I listed the areas in the check list for the 1st anniversary). After the re-tightening, it is much better then before.
