Log Home Checks: Why They Should Be Properly Sealed Understanding Checks in Log Homes

If you're purchasing a log home, one of the first things you may notice is long cracks running along the logs. These are commonly referred to as checks .

In many cases, checking is a natural part of the drying process as logs lose moisture over time. Small checks are common and do not necessarily indicate a structural problem. However, large or improperly maintained checks can allow water to penetrate deep into the log , creating conditions that may lead to serious deterioration.

When checks face upward or become large enough to collect water, rain can penetrate into the interior of the log.

Over time, this moisture may contribute to:

• Reduced structural integrity of the log.

Once decay begins inside a log, repairs can become costly and may require partial log replacement.

Not every check requires repair. However, larger upward-facing checks that can trap water should be evaluated and sealed .

• Cleaning the check to remove dirt and debris.

• Allowing the wood to dry if moisture is present.

• Installing an approved foam backer rod in deeper checks when appropriate.

• Applying a high-quality, flexible log home chinking or log sealant specifically designed for exterior log construction.

Using the proper sealant allows the log to continue expanding and contracting with seasonal moisture changes while helping prevent water intrusion.
