Diamond S. Portable Buildings is a family business owned by Tommy Santos and Brittnee Willis. We launched this new venture September 13, 2012 in Castroville, Texas thanks to help of our friends at True Value. We are 100% commited to Derksen Buildings and are proud to be your local Derksen dealer. The high demand for quality portable buildings and the great reputation of Derksen became very apparent when I was selling real estate in Bandera, Texas. So when the opportunity to open our own dealership near my hometown of Hondo, Texas opened up, we jumped on it! It is a high priority to me and my family to provide a quality building with a great deal of emphasis on customer service. Diamond S. Portable Buildings is open Monday thru Saturday from 10:00 AM to 6:00 PM. Closed on Sunday.
