Here we the types of sealants, chinking, splines or gaskets used during the construction of both traditional rough cut logs and modern milled log or solid log houses.
Readers should also see Spline Gaps & Gasket Omissions and Log House Leak Diagnosis & Cure. Our page top photo shows a modern milled log that uses a double raised rib or "spline" that mates itno a groove milled into the bottom surface of each log above. Gaskets (or in some cases caulk) are used on top of each spline (or on occasion along side them) in this design.
This series of articles provides information on the inspection and diagnosis of damage to new and older log homes and includes description of log house and log siding insulation values and alternatives, and also a description of the characteristics of slab-sided log homes as well as all other types of log home construction. We include illustrations of log structures from several very different areas and climates in both the United States and Norway. Our page top photo shows a modern kit log home constructed in New York State.
For modern kit and factory-sourced log structures we include details of common construction and building defects that cause water and air leaks and ultimately rot damage and we point to key problem areas that need to be inspected carefully when buying or maintaining a log home.

On both traditional rough-cut log buildings and on modern kit logs and milled log structures there are many designs for sealing the interfacing logs as well as sealing at windows, doors, and building eaves. Here we provide photos and text of basic log sealing methods, both traditional chinking and weather stripping and modern splines, gaskets, and caulks.
Traditional Log Walls Used Chinking not Splines nor Gaskets
As our photo (above left) shows, a traditional log house, built from individually-cut logs, may have included cutting or sawing the mating surfaces of horizontally (usually) or vertically (less common) placed logs against one another to obtain a flat surface. Other homes were constructed with fully-round logs and no planing of the mating surfaces.
But in all cases, to avoid terrible drafts and water leaks, a variety of log wall chinking methods were used between the logs of a log house:
Single-Splined Log Mating Surfaces
Double Splines Between Log Mating Surfaces
Caulk or Gaskets Used at Multi-Splined Log Mating Surfaces in a Log House Wall
We advise against simply using generic caulks in these locations.
Luckily, and probably because this is a common error, there are special products that can be used to remedy leaks in log walls. If inspection or if cold, windy weather reveals air infiltration leaks, call your inspector or log manufacturer for suggestions for special log chinking, caulks, or other log home crack or leak sealants.
