What are log checks?

Checks are cracks that split open on logs. Logs try and equalize with outside humidity. Logs should be under 20 percent moisture content.

Where your logs dried or kiln dried before your structure was built.

Checks should be sealed if over 1/4" wide and on the top/curved section of the log.
Use Permachink log check to seal these areas.

Water can settle in these open checks. Checks near windows can cause more problems.
