Air Infiltration Repair for Log Homes

Keep the Outdoors Outside

Even the best-built log homes can develop small gaps over time that allow outside air to enter your home. Because wood naturally expands and contracts as it gains and loses moisture, tiny openings can form between logs or around key connections. Left unaddressed, these gaps can reduce your home’s energy efficiency, create drafts, and allow moisture and pests to find their way inside.

At Log Building Maintenance and Restoration, we specialize in identifying the source of air infiltration and providing long-lasting repair solutions. While most log homes are built with effective sealing systems, those materials can wear down or fail with age and exposure to the elements.

The most common areas for air leaks are log-to-log joints, corners, and other connection points. In many cases, these issues can be resolved by professionally applying high-quality exterior caulking designed specifically for log homes.

Occasionally, deeper cracks—known as checks—can develop in the logs themselves, creating a pathway for outside air and moisture. When this occurs, we use a professional backing rod and flexible sealant system to properly fill and seal the opening while allowing the log to continue its natural movement.

Whether you’re noticing drafts, rising energy costs, or simply want to maintain your home’s performance, our experienced team can inspect your log home, identify problem areas, and restore a tight, weather-resistant seal that protects your investment for years to come.
