Keeping the Elements Outside Where They Belong
Professional diagnosis and targeted sealing solutions for drafts and air infiltration in log homes.
Request an EstimateFinding the Source of Air Infiltration
There are multiple reasons for possible air infiltration in log homes. Wood is a hygroscopic material, meaning it naturally gains and loses moisture over time. As the logs respond to changing conditions, small gaps can sometimes form between them.
Most log home manufacturers use effective sealing systems between the logs, but those systems can occasionally fail. When that happens, Log Building Maintenance & Restoration has the experience to diagnose the source of the air infiltration and recommend the right repair.
Natural Wood Movement Can Create Gaps
Wood is always responding to changes in moisture. That natural movement is part of owning a log home, but it can create opportunities for air to move through failed or separated sealant joints.
The key is determining whether the draft is coming from a log-to-log connection, a check in the wood, or another localized failure so the repair can be focused where it is actually needed.
Log-to-Log Sealing
Most air infiltration failures occur at the log-to-log connections. In many cases, these areas can be corrected by properly caulking the exterior joint and restoring the seal between the logs.
A targeted exterior repair can help stop drafts without unnecessarily disturbing sound areas of the home.
Backing Rod & Caulk Repairs
In rarer cases, a check in a log can create a pathway that allows outside air to reach the interior of the home. When that occurs, we use a backing rod and caulk system to properly fill and seal the opening.
This approach provides the support needed behind the sealant and helps create a durable repair that can accommodate normal movement in the wood.
Diagnose First. Repair What Actually Needs Attention.
Drafts can be frustrating, but the solution does not always require a major restoration. Our goal is to identify the exact source of the infiltration, evaluate the condition of the surrounding logs and sealants, and make the repair appropriate for that specific area.
By addressing the cause instead of simply covering the symptom, we can help improve comfort while preserving the existing log structure and finishes wherever possible.
Common Questions About Drafts in Log Homes
Why do gaps form between logs?
Wood is hygroscopic, so it naturally gains and loses moisture. That movement can occasionally create gaps or place stress on existing sealing systems.
Where does air infiltration usually occur?
Most failures occur at log-to-log connections where the original sealing system has separated or failed.
How are failed log-to-log seals repaired?
In many cases, the affected exterior joint can be properly caulked to restore the seal and stop air movement.
What if a check in a log is causing the draft?
When a check creates a pathway from the exterior to the interior, we typically use a backing rod and caulk system to fill and seal the opening.
Does every draft require a major restoration?
No. Many air infiltration problems are localized. Proper diagnosis helps identify the exact source so the repair can be limited to the areas that actually need attention.
