What happens in this clip
With all the reinforcements and adhesive in place, the stairs should now be completely solid and free of squeaks. To test the repair, walk up and down the stairs, specifically listening for any remaining noise. The improved stability and filled gaps will prevent the movement that causes squeaking, allowing for quiet and safe use of the stairs.
Goal: Confirm the elimination of squeaks and stability of the stairs.
About the full video
This project demonstrates a method to eliminate squeaky stairs by reinforcing the treads and risers from underneath. The process involves removing any existing inadequate braces, applying an expanding wood adhesive into gaps, and then screwing solid timber pieces to securely connect the risers and treads, thereby stopping movement and noise.
Step 5 of 6: Test for Squeaks
Once all shims and glue blocks are in place and any screws are secured, have your assistant walk on the stairs again. Listen carefully from underneath to confirm that the squeak has been resolved. If the squeak persists, you may need to repeat the process with slightly different shim placement or try adding more shims and glue.
