Chinking or caulk? It depends on where it's going on your log home.
🪵 Between the logs → chinking. Chinking fills the joints between your logs with that textured, mortar-look band. It moves with the logs as they expand and shrink, so the seal holds.
🪟 Checks, cracks and trim → caulk. Use caulk to seal log checks and cracks, around doors and windows, along corner boards, and where wood meets the chimney. That keeps water, air and bugs out.
We like Sashco Log Jam for chinking and Sashco Log Builder for caulk.
