Log Home Chinking & Sealing

Chinking that fails lets water in and conditioned air out. We install and repair chinking that stays flexible and stays put.

What Chinking Does

The seal between every log

Chinking is the flexible seal that closes the joints between logs. When it's right, it moves with the logs as they expand and contract through Texas seasons. When it's wrong, or old and cracked, every joint becomes a water path, and water paths become rot.

We handle new chinking, re-chinking over failed material, and sealant work around windows, doors, and checks. You can see a recent full back-porch chinking job on our Our Work page.

Signs You Need It

When to call about chinking

  • Cracked, hardened, or pulling-away chink lines
  • Drafts you can feel near log walls in winter
  • Water staining on interior walls after storms
  • Gaps opening at log checks (cracks) wide enough for a fingertip. See our post on turning log checks out
  • Wasps, dirt daubers, or ants finding their way inside

Chinking is usually quoted alongside an overall inspection. Small chinking jobs often reveal (or prevent) bigger problems.

Common Questions

Questions we get asked

Do you repair log home chinking?

Yes, that is a big part of what we do. New chinking, replacing failed chinking, and sealant work around windows, doors, and log checks. The inspection tells us whether your walls need spot repair or a full redo.

What is the difference between log chinking and log caulking?

Chinking is usually anything over about half an inch wide. But the main differentiator is usually the color: log caulking blends into the stain color so it conceals, or nearly conceals. Log chinking is almost always a contrasting color. Chinking also has a grit in it to imitate a mortar look. Caulking is smoother and meant to have a texture closer to the wood.

Is chinking necessary on a log home?

If your home was built with chink joints, yes, it is not optional. Chinking is what seals the gaps between logs. When it fails, every joint on the house becomes a water path, and water paths become rot repair bills. When installed properly it is very good at shedding water and keeping it running to the outside. That said, it is still second to having proper roof overhangs.

How do I know if my chinking needs to be replaced?

Chink lines that are cracked, hard as concrete, or pulling away from the logs. Drafts near the walls in winter. Water stains inside after a storm. And if wasps and ants are finding their way in, they found a gap.

Does chinking really affect energy bills?

Yes. Failed chink lines leak like an open window spread across every wall of the house. Good chinking keeps the air you paid to condition inside where it belongs. Sometimes when I am standing on scaffolding up against a poorly chinked or unchinked wall, I can feel the cold air coming through in lines along the wall.
