I was considering hiring KJI to build my home. After doing some investigating, I discovered that KJI had several complaints about the shoddy homes built. I also found out that Mr. Herron behaves in an inapporpriate manner toward women. I strongly urge anyone looking at this sight to NEVER work with KJI.
