Step 4 · Address Loose Stringers

Stringers are the structural supports that run along the sides of the staircase. If a stringer has come loose from the wall framing, it can cause significant movement and squeaking. To fix this, you'll need to locate the point where the stringer meets a wall stud. Drive long wood screws from the back of the stringer into the stud, or from the stud into the stringer, to firmly re-secure it. This provides the necessary rigidity to prevent movement and eliminate the squeak. Again, ensure screws are appropriately sized to achieve a strong connection without damaging the surrounding wood or drywall.
