The Leading Experts in




JDM Contractors is a full service general contracting firm founded with the key objective of working for a select group of clients at any one time and to dedicate only senior personnel to provide premium service and achieve results for them. We draw on our extensive experience over the years and use it to our client’s advantage. The structure of our firm is built on the seamless overlap of our individual areas of strength, pre-construction and estimating, project management, and field supervision and operations. Each of the three principals has an extensive track record of delivering fast-paced complex projects with stringent budgets and challenging schedules.


Throughout our over 70 years of combined experience, we have developed strong relationships with Los Angeles area clients, subcontractors, architects and consultants, and city building officials and fire departments. These bonds are based on a creative, proactive, and  hands-on approach to all aspects of our projects, particularly service and process, schedule, budget, and quality. Our clients are our greatest asset and we are committed to providing exemplary service from only the most senior people in our firm. We believe our extensive experience with re-stack projects will be a huge asset to the project.
