Log Cabin Rot Service

Log rot is a form of decay that affects wood, particularly in log homes where untreated or poorly maintained wood is exposed to moisture and fungi. It's a natural process where wood is broken down by certain types of fungi that thrive in damp conditions. This decay primarily occurs in the sapwood of logs and timbers, which is the outermost layer of wood and is more susceptible to moisture intrusion.

Preventing Log Rot

Prevention is key to avoiding the hassle and expense of the damage log rot can cause. Here are some preventive measures you can take:


  • Masonry foundation:  We recommend ideally 3’ above ground level before your logs start to avoid splash.


  • Overhangs: We recommend overhangs because the more water you keep off of your logs the longer your protection system will last.


  • Transparent products: Only apply transparent products on your logs or larger timbers. These products tend to trap moisture and they make it harder to detect discoloration in the early stages of rot.


  • Good Ventilation: We recommend a minimum of 2 ft air gap between exterior logs and shrubbery however four (4) ft is ideal


  • Proper maintenance: Regularly inspect the exterior of your log or timber home for signs of damage or decay and address any issues promptly.


  • Effective drainage: Put roofs over Exterior home appliances/accessories such as AC Condensers, Propane Tanks, Mini-splits to prevent rain from splashing onto you logs.


  • Landscaping: Have soft Landscaping to prevent splash.


  • Cobra rods: Install cobra rods in areas with a high probability of repeated moisture to help prevent Rot. Cobra rods dissolve when wet and product moves with the moisture not allowing the logs to rot. Not a permanent fix but helps longevity of high moisture areas. A common place for cobra rods is in the bottom 1-2 rows of logs along a concrete sidewalk within a few feet of your logs.


  • Sealing and staining: Apply a quality sealant and stain to the exterior wood surfaces every few years to create a protective barrier against moisture and UV rays.


  • Prompt repairs: Address any leaks or damage to the roof, windows, or doors immediately to prevent water infiltration into the wood.

What are the Effects of Log Rot?

Log Rot usually does NOT effect structural integrity of the entire structure for a very long time say 10 years. Log Cabins are very forgiving as the exterior walls are essentially solid and load bearing. It can take a long time for log rot to become a structural issue. Most log rot does not penetrate past 2-3” before it tends to spread out horizontally with the grain of the wood, and most logs are 6-8” thick.


  • Structural damage: Log rot compromises the integrity of the wood, weakening the structural stability of the entire building.


  • Aesthetic deterioration: Rotting logs detract from the beauty and charm of a log or timber home, diminishing its visual appeal.


  • Health hazards: Certain types of fungi associated with log rot can pose health risks to inhabitants, especially those with respiratory issues or allergies.

Log Rot Repair

Not every case of log rot can be prevented, and it’s recommended to seek professional services to help restore what was damaged. Addressing log rot promptly is necessary to prevent further damage and restore the structural integrity of the wood. Log rot repair typically involves the following steps:


  • Assessment: A thorough inspection is conducted of the affected areas to assess the extent of the damage and identify the underlying causes of the rot.


  • Removal of affected wood: The rotted portions of the logs are cut out using appropriate tools such as chisels, saws, or grinders until healthy, solid wood is reached.


  • Add closed cell foam: After excavating the rotted areas of logs and installing the new wood for refacing, we then install a closed cell foam behind the new facing to ensure there is no void that could result in condensation or critters getting inside your logs. We then caulk the perimeter of the new refaced log to seal it.


  • Treatment: A wood preservative or fungicide is applied to the remaining wood to prevent future fungal growth and protect against moisture.


  • Replacement: If the damage is extensive, entire logs or sections of timbers may be replaced to ensure structural integrity.


  • Sealing and staining: Once the repairs are complete, the wood is sealed and stained to provide an additional layer of protection against moisture and UV damage.
