Formed in 1992 as Stewart Builders, LTD. D.B.A. Keystone Concrete Placement by Don Stewart, Craig Stewart, Mark Stewart, and Brad Stewart.

The company focuses on providing the construction market with a quality turnkey concrete product, and soon after amassed a resume of impressive projects and a reputation for getting the job done. Over the years this reputation has developed profound relationships with Owners, Architects and Engineers. In 1996 our owners decided to venture into the General Contractor market to help build these relationships.

Stewart Builders, Inc. was formed with the focus on acquiring all work through established relationships. In the late 90’s the Houston economy was growing rapidly, and high-rise towers were the new norm; at that time customers of Keystone Concrete Placement were asking for Elevated Concrete work, and in 2000 Keystone Structural Concrete was born with the sole focus on complex turnkey elevated concrete projects. As the economy strengthened so did we, and in 2001 Keystone Site work was formed focusing on dirt and utility work and in 2009 Key-Scape’s to focus on landscaping. In 2011 Mark Ludlow and the Stewart’s partnered to form Ludlow and Associates, a general contractor focusing on hi-rise condominium projects.

Concrete is the heart of our business and has been the foundation to allow us to move into multiple construction related market sectors over the last 25 years.
