This focus would be towards providing windows/doors/gazebo kits rather than general building and construction. The two companies were now known as K.C. Construction and Cedar Gazebo's Inc..In the 90's due to the success of each venture, the companies would split, Jim with K.C. and Eugene with Cedar, in order to streamline each process. POW!
