Questions about chinking

[pfletcher]

Hi, first time posting. We recently bought a log home that was built in the 1930's. It looks like the chinking is some sort of mortar, and is cracked or coming out in places. My question is, is the chinking structural? Meaning if I replace the missing sections with something like Log Jam that's a more flexible material, would that affect the stability of the logs? And is Log Jam recommended, or should I go back with the mortar?

The chinking usually holds in some kind of insulation that keeps the wind out. Yes, you could patch it with a synthetic chinking (just like you could use synthetic logs) but I'd tend to patch the chinking with more mortar. Mortar is cheap, easy, long lasting, and it's real.

Obviously we don't have all the information needed but I can't imagine a log home that has chinking that would be structural.
