Microorganisms can multiply in them, which leads to the destruction of logs.
The optimal way to eliminate the problem is to close the cracks. First, cracks are as follows, cleaned of garbage, and then they are treated with antiseptics.

After such a seal, cracks do not spoil the aesthetic appearance of the facade and do not threaten the durability of the construction.
