Mark Nelson of Nelson Restoration was recently working on a job up in Grand Teton National Park. Mark needed specific information to share with key decision makers that compared preservation of log structures using older methods of mortar and linseed oil with modern products. Sashco was honored to partner with Mark provide a report outlining the pros and cons of historic preservation. Below is that report. Mark was able to clearly communicate the value of using a specialized log restoration contractor who uses modern products and won some future business as a result.
