Wood floors creaking noise

Q: Is there any way to stop the creaking of our hardwood floor? It is beautiful but the noise is too much!

A: Not really. Fix the sub floor and you will have a sound floor. If you have access to the sub floor from the basement, you may be able to screw short pieces of wood across a number of boards to stabilize them.

A: I don’t know what this floor is installed on top of nor whether an appropriate amount of nails, cleats or staples was used. Clearly the floor is moving. It could also be expansion and contraction noises occurring. Do you notice any large gaps appearing or conversly do you see any cupping of the boards that would indicate expansion from moisture?

A: The structure floating floors sits on needs to be very near to perfectly flat, with any voids being filled with building paper or the like. I suspect this flex and popping sound are caused by this situation.
