Chinking and caulking in log homes may be done for aesthetic or practical purposes. Many log buildings need chinking or caulking to seal gaps that develop between the logs. Over time, logs shrink and shift, which creates gaps that allow air and water to seep between the logs. Proper chinking and caulking seals these gaps, reduces energy expenditures, and keeps log homes and buildings healthy and comfortable.

Our teams use time-tested chinking and caulking procedures to ensure that your log home or log building is sealed properly. Chinking comes in about eight different colors – from white to a rich grey, which looks similar to mortar, and from light tan to dark brown. The choice of color is mainly a personal choice of the homeowner. In general, if the logs are small and there will be many chink lines in between them, it is best to stick to a color of chinking that best matches the stain color on the logs.

Procedure for Chinking and Caulking

Some homeowners try to chink or caulk their log homes themselves, but it takes experience and the right tools to smooth the lines so they look uniform. Edmunds & Company has many years of experience chinking and caulking different types of log buildings to restore them to their original beauty and seal gaps that have appeared over the years.


Both chinking and caulking rely on latex polymers for adhesion. Chink has fine sand particles added to it where caulk doesn’t. The sand gives the chink a dull or “flat” appearance. Just like aggregate adds strength to a concrete slab – the sand adds strength to the chinking material.

Chinking can be used in lines that are from a half-inch to six inches or more wide. When the line is less than a half-inch in width, caulk is a usually a better choice. Edmunds & Company uses Perma-Chink brand chink as our preferred chinking and Big Stretch by Sashco as our preferred caulking because over the years, these two products have performed the best and are the most cost effective.
