Log Chinking/Caulking

Chinking and caulking are essential components of a well-maintained log home, serving both functional and aesthetic purposes. The process involves sealing the joints between logs to prevent air infiltration, moisture intrusion, and insect entry. Chinking is typically used for larger gaps, creating a flexible yet durable seal that accommodates the natural movement of logs over time. A foam backer rod is used prior to the application of the caulking. This method assures a 3-way bond in which keeps the material from failing or separating. The caulking is applied to all upward cracks and checks that are ¼ inch or larger. This will seal out water and drafts. This sealing process is critical for maintaining energy efficiency, preventing rot and mold, and protecting the structural integrity of the home. Without proper chinking and caulking, log homes are vulnerable to weather damage, heat loss, and pest infestations. Professionally applied products not only help preserve the logs but also enhance the appearance of the home by giving it a clean, finished look. All caulking and chinking material is professionally applied and tooled by hand to assure a neat smooth appearance, unlike many “popcorn” looking applications that will fail due to being installed in a unprofessional manner.

Northern Log Home Restoration uses a backer rod along with a very high quality chinking material that stretches to accommodate most log structures. When a log goes through the drying process there is movement that occurs as well as checking (cracks in the logs). Our recommendation is that all upward checks of 1/4 inch or larger be filled with a foam backer rod prior to being caulked. The foam backer rod has three main purposes. It allows the applicator a two point adhesion which in return provides better elasticity during log movement, uniform thickness of caulk, and it saves product which in return will save the customer money.
