Step 2 · Access from Above

Depending on the construction of your staircase and the floor above, you may need to access the underside of the stairs to address the squeak. This is often the most effective way to secure loose components. If you have a basement or crawl space below the stairs, you can likely get underneath. In some cases, access might be gained from an attic space if the stairs are near the top of the house. The goal is to be able to see and reach the area where the tread meets the riser or stringer, or where the riser meets the stringer, which are common points of squeaking.
