What to Do About Cracks in Your Cabin’s Logs

Living in a log cabin comes with a lot of perks—the rustic charm, the cozy atmosphere, the beautiful woodwork! But it’s also a fact that log cabins tend to require more maintenance than other types of homes. One common issue is cracks in the logs. What do you do when you notice a long, unsightly crack running across the side of your home? Here’s how to effectively manage cracks so they don’t cause further damage or compromise the integrity of your log cabin.

Clean the Cracked Area

First, you’ll need to clean the crack and the area around it. Any dirt, loose wood fibers, or old finish can prevent the sealant from properly adhering to the log. You can use a stiff brush or a vacuum to get rid of any debris. For stubborn grime like mold, mildew, or sap, try a gentle soap and water solution to scrub the area clean. Afterward, let the area dry completely before you move on to the next step.

Apply Backer Rod

For larger cracks, a backer rod is a very useful material. You insert this flexible foam rod into the crack before applying any caulk. It helps control the depth of the sealant, which creates a better seal and uses less caulk.

Caulk the Crack

With the crack prepped, you can now apply a quality log caulk. It’s a special type of caulk that remains flexible after it cures. This quality allows it to stretch and compress as the logs expand and contract with temperature and humidity changes. You’ll apply the caulk over the backer rod, then smooth the bead with a wet finger or a trowel for a clean finish.

Restain Your Logs

Staining your log cabin home can help prevent cracks in the first place by protecting the wood from moisture and UV damage. Once you’re done repairing any cracks, check to see if the stain is still effective. If not, it could be time to restain it, which gives your cabin a fresh look and added protection.

When Cracks Become a Problem

If you notice cracks in your cabin’s logs, don’t panic, take action! Most cracks, when caught early, don’t pose much of a risk to the structure of your home, and are easy to repair with a backer rod and some caulk. But if you find a crack that runs through the entire log or see signs of water damage, it may be time to consult a professional for advice.
