Log cabin maintenance you can do yourself – caulking cracks in your logs

Log home maintenance issues sometimes need to be resolved by experts. That is where we come in. But there are also things that the homeowners can do to insure that their logs stay “healthy”.

Logs naturally do develop some cracks or checks. As wood dries, the difference in surface tension and moisture gradients between the inner and the outer parts of the logs cause checks. This is  part of the charm of the log home.

Classic example of up-facing checks needing caulking.

These cracks can face up or down, depending on where they are on a log. Logs with cracks that face upward can be susceptible to rot because they allow the water to travel deep into the logs, where rot starts. The more exterior areas of logs can usually dry out after a rain because of the wind and sun, but the more interior areas can remain wet longer. When this happens, they can reach the right moisture point that allows rot fungi to grow.

Here are the three criteria we generally use when determining if it is necessary to caulk checks on log homes:

If all these criteria are met then the check needs to be filled.

Proper log home maintenance is your best insurance against needing more costly repairs down the road.
