ProblemSqueaks are caused by wood rubbing against wood or wood rubbing against nails in a floor that has loosened. If you can get to your floor from a basement or crawlspace, most homeowners should be able to repair a squeak easily with the following quick fix:
While you are standing under the area that is causing the problem, have someone walk across the floor so you can locate the exact location of the squeak. Coat a shim with wood glue and tap it lightly into the space between joist and floor, making sure that you don't raise the floor further by pushing it in too far.
A: The noise you are hearing is the plywood riding up and down on the shank of the existing nails. The wood has shrunk over time allowing this to happen.
One must take up the carpet and pad, and screw down the plywood floor into the floor joists. You will probably need a carpet man to cut and re-seam the carpet.
If you can get under the floor, you may avoid pulling up the carpet. Please visit Service Magic. Enter a service request for the kinds of tasks you need, and be matched with the ideal service professional in your area.
