In Houston, Marek Interior Systems began in 1938 when gypsum wallboard was a new way to finish the interiors of houses. This new product would change interior construction and, taking advantage of this newfound opportunity, Marek Brothers Sheetrock was formed. It was an instant success. In the 1960 s, the Mareks expanded into commercial interior construction. As the largest and most respected residential contractor in the city, it soon made its mark in the commercial field. As the residential company maintained its leadership role, the commercial division took off opening offices in San Antonio, Austin, and Dallas, Texas. By the end of the decade, Marek craftsmen had finished out enough office space to fill a building almost five miles high. Today, the Marek Family of Companies continues to be a leader in residential and commercial interior construction.
