Step 2 · Examine Carpet Tread Adhesion

Using a putty knife or your fingers, gently lift the edge of the carpet tread, particularly at the nosing where it meets the edge of the stair. Inspect the underside of the carpet and the surface of the stair tread for signs of dried-out adhesive, insufficient glue, or complete separation. Look for any debris or residue that might be preventing proper adhesion.
