Floors - QUESTIONS & ANSWERS
How do I fix a squeaky hardwood floor?
The squeak is probably in the subfloor over a floor joist. Best way is to run screws into the subfloor through the joint nearest the squeak. If this is awkward, first screw a 2 x 2 to the side of the joint tight to the subfloor, then screw up through the 2 x 2 into the subfloor.
