Diagnose Creaking Causes

What happens in this clip

Before fixing, it's crucial to understand why stairs creak. Over time, timber warps, dries out, and moves, creating gaps. There are two primary locations where creaks originate: 1. **Riser-Tread Rebate**: The riser (vertical part) sits within a rebate (groove) in the tread (horizontal part). When the riser moves within this rebate as you walk up or down the stairs, it generates creaks. 2. **Tread-Riser Underside Gap**: Gaps can form between the bottom of the tread and the top of the riser below it. The tread moves up and down slightly, rubbing against the bottom of the riser, causing squeaks. The video notes that the majority of noise in the demonstrated stairs comes from the riser-tread rebate. Both issues will be addressed.

Goal: Identify the structural reasons for stair creaks.

About the full video

This DIY project provides a step-by-step guide to fix creaky stairs without needing access from underneath. The process involves removing the carpet and underlay, diagnosing the causes of creaks (movement in the tread-riser rebate and gaps between tread and riser), and then securely bonding and screwing these components together using various adhesives and screws. The final steps include reinstalling the underlay and carpet.

Step 1 of 7: Inspect Carpet Tread Noise

Systematically go up and down the stairs, applying firm pressure to each carpet tread, especially at the nosing and center. Listen closely to pinpoint the exact areas on each tread where popping or creaking sounds originate. Note any specific patterns or triggers for the noise (e.g., only when stepping on a certain spot).
