Assessing older log cabin for bad logs

That’s a very valid concern — visible rot usually means there’s more going on. You can’t reliably tell from looks alone; rot often starts inside the log and works outward. Thermal imaging can sometimes help by showing moisture patterns or temperature differences, but it does not diagnose rot by itself. The most reliable way is a hands-on inspection that checks moisture levels, wood hardness, and problem areas like bottom logs, windows, and rooflines.
