My deck stairs feel loose and shaky, and I am trying to figure out the best way to reinforce them. Should I start by checking the stringers and connections, or is there a better way to find where the movement is coming from?
The deck stairs feel loose and unstable. At the bottom, there is a 4–6 inch gap between the stairs and the concrete patio, so the stair structure does not appear to have solid support or a secure connection at that point. I would like to understand how the stairs should be properly anchored or reinforced. Would reinforcing the handrails help solve the instability, or does the stair structure itself need additional support?
