Step 3 · Secure Loose Tread/Riser

Once you have accessed the underside of the stairs and located the loose connection between a tread and a riser, the next step is to secure them. This is typically done by driving long wood screws through one component into the other. If the tread is loose on the riser, drive screws from the underside of the tread up into the riser. If the riser is loose on the tread, drive screws horizontally through the riser into the tread. It is critical to use screws that are long enough to get a good grip in both pieces of wood but not so long that they will poke through the visible surface of the stair. Pre-drilling pilot holes can help prevent the wood from splitting, especially in hardwood.
