Reinforce from Underside with Screws

What happens in this clip

As an alternative or supplementary method, the narrator suggests inspecting the underside of the staircase. If there is an accessible area (such as a cupboard or an open-plan design where the underside of the stairs is exposed), additional screws can be driven through the risers and into the back of the treads, or through the stringers into the treads and risers. This mechanical fastening will pull the components tightly together, eliminating movement and preventing creaking.

Goal: Provide additional mechanical reinforcement to stair components from below.

About the full video

This video addresses common creaking noises in stair treads by first demonstrating the issue, then showing the removal of unsuitable previous repairs (like expansion foam), and finally advising on effective methods using specialized adhesives or mechanical reinforcement to create a silent staircase.

Step 6 of 7: Secure from Underside (if accessible)

From beneath the stairs, locate the area of the squeak. Secure wood blocks or metal angle brackets using wood screws to bridge the gap between the tread and riser, or tread and stringer, thereby reducing movement and friction.
