Premium Graded Logs

High Quality Homes Start with the Right Logs

We use only premium logs cut from the heart of the tree. To prove this, all of our log homes are graded to the standards provided by the Log Homes Council, and come with their own grading certificate. Never settle for anything less than graded logs for your log home.

To reduce the checking (or cracking) in our log walls, we never kiln dry our logs. This process stresses the logs and creates unnatural checking. Instead we air dry them so the drying process occurs naturally. Our logs are also wider than they are tall, which minimizes checking along the exposed log surfaces.

Log Home Interlocking Joinery Example

Interlock Joinery System

Using what we call the Interlock Joinery System, our log homes are built to be weatherproof and draft-free. While many log home companies seal with little more than caulking, Real Log Homes are manufactured using a sophisticated tongue and groove system.

The system incorporates durable foam gaskets and PVC Locksplines to seal all joints between logs, at windows/doors and at corners. Logs are tightly connected using Olympic OlyLog® fasteners. You won’t find a log home joinery system that is more weatherproof or one that requires less maintenance.

The graphic below shows our standard log package components. Keep in mind that that any of our homes can be customized to meet your style and budget.
