Bill Teague


Bill Teague has been part of the construction industry for over 40 years and has succeeded in using his experience to create efficient and safe civil construction companies. After developing a multimillion-dollar company, Bill decided to take his knowledge, start from the roots, and grow a small and high-quality construction company. Starting with just one crew, Bill grew Old Line Construction into what it is today. Over his years of working in construction, Bill has completed projects including heavy site excavation, storm, sanitary, and water main line installation, directional drilling, pipe rehabilitation, communication power conduits, fiber optic, and coaxial cable installation, paving, landscaping, historical areas, and environmentally sensitive areas. Bill has spent most of his career managing and running not only large projects but large crews and clientele as well. During his lifetime, Bill has always maintained a safe, reliable, high-quality, and productive team. Old Line is a prime example of the kind of quality work Bill strives for.
