Determine if the chinking needs to be replaced.

The first step is to determine if the chinking needs to be replaced. If it is mortar and is cracked all over and chipping, then it is time to upgrade. If the chinking is synthetic, and is coming unsealed at the top and bottom all over the log home, then it is time to replace it.
