I discovered a section of log where water made it into a ”top-half” crack and rotted away a section of log. The rotten section is perhaps 1.5” high, 2 inches deep and 24 inches long. fortunately it does not bear a huge amount of direct load, as it is under a window sill. However – what are my options for proper repair (from inexpensive to expensive) in this case? THANK YOU!! 🙂
