1. 2:45–5:32 Identify Squeak Causes and Mark Fixings From How to Fix Squeaky Stairs from Underneath with Shims and Glue Blocks, Step 1: Locate Squeaky Tread

   The presenter explains that squeaks are primarily caused by movement at the front edge where the tread meets the riser, and at the back edge where the tread meets the riser below. This movement results from wood drying out and wedges loosening over time. To address this, an adjustable set square is used to find the approximate midpoint of the joint between the tread and the riser. This measurement (e.g., 8mm) determines how far from the edge of the tread the screws should be placed. Use a piece of scrap wood as a guide and a pencil to draw a straight line along the tread, where the screws will be inserted, ensuring a consistent distance from the edge.

   Examine the exposed wooden treads and risers. Squeaks typically occur where the tread meets the riser, often because the original wooden blocks or pins supporting them have loosened over time due to wood drying out. To secure these, you'll need to drill and screw through the tread into the riser. To ensure consistent placement of screws, use an adjustable set square to find the precise measurement from the back edge of the tread to the rebated slot where the riser sits. Mark this distance on each tread. Then, using a piece of wood or a straight edge, draw a straight line across the tread, equidistant from the riser below. This line will guide the placement of the screws. The host suggests five fixings per tread, spaced equally, allowing for the wood to be pushed up to one edge of the stringer.

3. 6:13–6:27 Secure Front Treads with Screws From How to Fix Squeaky Hardwood Stairs from Above, Step 3: Secure Loose Tread/Riser

   Once all pilot holes with countersinks are prepared, insert the appropriate size screws (e.g., 4.5 x 40mm screws) into each hole. Use the cordless drill to drive the screws down until their heads are flush with or slightly below the surface of the tread. This action will pull the tread firmly against the riser, reducing movement and eliminating squeaks from the front joint.

4. 6:40–7:13 Apply Wood Glue (Back Risers) From How to Fix Squeaky Stairs from Underneath with Shims and Glue Blocks, Step 3: Apply Wood Glue

   Before adding mechanical fasteners to the back risers, apply a generous bead of wood glue along the entire seam where the top of each riser meets the underside of the tread above it. The goal is for the glue to seep into any gaps and expand slightly as it dries, creating a strong bond and further eliminating movement. Allow the glue a few minutes to settle before proceeding with drilling.

5. 11:15–11:37 Final Inspection From How to Fix Squeaky Hardwood Stairs from Above, Step 5: Test for Squeaks

   Once the carpet is fully reinstalled, walk up and down the stairs to test for any remaining squeaks or movement. The stairs should now be silent and solid. Visually inspect the carpet to ensure it is evenly laid, without wrinkles or loose spots. This concludes the repair process.

   Once the carpet is fully reinstalled, walk up and down the stairs to test for any remaining squeaks or movement. The stairs should now be silent and solid. Visually inspect the carpet to ensure it is evenly laid, without wrinkles or loose spots. This concludes the repair process.
