Louis Sebastian Contractor is a Baltimore-based construction company specializing in residential concrete and masonry services.  Founded in 1977, Louis Sebastian Contractor has over 37 years of experience in custom concrete, brick, stone, and stucco construction.  None of our work is sub-contracted.  Therefore, you will always see the owner of the company, Luigi, a.k.a. Louis, working with his team every day.  We will only perform one project at a time until it is fully completed.  

Our goal is to provide our customers with quality and service always. We work closely with our clients in order to determine what they need and want so that they are completely satisfied with our work.  We are proud of our reputation and we will always work to preserve our name in the field of residential construction.
