— Chinking & caulking
Chinking & caulking
Chinking is the flexible seal between your logs — it keeps out drafts, rain, and pests while letting the wood move with the seasons. Old mortar-based chinking cracks and falls out over time; we replace it with Perma-Chink Systems' synthetic chinking, engineered specifically for log homes to stretch and last far longer.
Why it matters
Stops drafts and water intrusion at gaps and checks
Flexible synthetic compound moves with the logs — no cracking
Backer rod (if possible) set first for proper depth and long-term adhesion
Tooled and textured to match traditional chinking by eye
— The product we trust
Built with the product the brand is named for

PERMA-CHINK SYSTEMS
Certified applicator
Maintained right, it keeps working
How to make it last: walk the joints after big seasonal swings and look for hairline separation at the edges. Catching it early means a small touch-up — not a full re-chink.
