Plywood floor squeaky in my new house. Which is all carpeted. Separate wooden bridging members to eliminate noise problems. Before i attempt to try anything i thought i would see what you suggested. Squeaky floors may alert you to kids sneaking in past curfew but they ve got little else going for them.

Annoying floor squeaks common in many homes typically occur after the house has settled and flooring lumber has dried out and shrunk. Squeaks happen when a house settles and wood flooring dries and then expands. I have posted the video below of the upper level. If the underside is covered you will have to work from above.

If the tops of the floor joist are not flat and level then the sheets of plywood or sub flooring will not be fully supported evenly. Nails rub on plywood when walking on floor and cause the squeak. I have some squeaks in my floor that i have narrowed down to exposed nails coming through the plywood sub floor from the basement which is not finished. This old house general contractor tom silva silences some squeaky floors.

For squeaky floor repair begin from underneath the floor if you can. When nailed down the sub flooring will be sucked down unevenly. Over time the portions of the floor that have been sucked down will try to go back to a flat and level position. With hardwood floors drive ring shank or cement coated flooring nails into the seams between boards.

This causes the floorboards to rub against each other or against the subfloor or against the nail casings.
