Kaper’s Building Material, Inc. is a local family owned and operated independent lumberyard conducting business from the same Northern Indiana location in Demotte since 1936 along with 2 showroooms located in Valparaiso and Crown Point.  Kaper’s is Northwest Indiana’s most complete source of residential building materials including outstanding framing lumber, Andersen windows, pre-hung interior and exterior doors, prefinished trim, cabinets, siding, roofing material, and most anything you need for your building needs.  With the addition of Kaper's sister company, Gold Standard Truss, we are able to offer the areas top quality Wall Panels, Roof Trusses, and Prefabricated Stairs. 

Over the years, Kaper’s has established a proven track record of responding to each customer’s productivity challenges.  In many respects, we are a throwback to a bygone era when lumberyards looked at their contractor customers as partners and understood that the survival of each was linked to the other.
