Costello Construction

Costello Construction is a Columbia, Maryland-based commercial construction contractor operating along the Baltimore/Washington corridor. We serve both the public and private sectors and specialize in corporate offices, fitness facilities, higher education projects, and urban infrastructure. Costello Construction provides a wide range of services including pre-construction analysis, design-build, and sustainable construction.Founded in 1993 on the principles of self-performance and a hands-on management approach, Costello Construction is a name synonymous with integrity, hard work, dedication and a reputation for building commercial structures of the highest quality.We owe much of our consistent reputation for quality construction to our approach of performing so much of the work ourselves. We typically self perform about 30% of the work on our projects, including all site work and concrete work. Our ability to self-perform, combined with the benefit of owning a significant amount of heavy equipment and large tools, helps us to reduce client costs and keeps our field crew in line with critical construction schedules. With a hands-on management style, Costello Construction stays in control of every aspect of the building process from beginning to end. Completing projects on time, every time, and within the allotted budget is simply our corporate standard, and our upper management sees to that personally.
