Costello Construction is a name synonymous with integrity, hard work, dedication, and above all, a reputation for building structures of the highest quality. Since 1993, the Columbia, Maryland-based company has provided general construction services to the public and private sectors throughout the Baltimore/Washington Metropolitan area.

Over time, Costello has built a diverse portfolio, spanning the markets of corporate, fitness, higher education, and site development.  The ability to self perform all site and concrete work has yielded countless project successes.

With a hands-on management style, Costello 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.

For more than 20 years, Costello’s experienced staff has constructed institutional-quality facilities. Employing approximately 50 industry professionals, Costello boasts a seasoned workforce that includes LEED AP project managers, Licensed Architects, and an entire crew of OSHA certified field employees. Throughout the company’s business history, one principal has remained unchanged—client satisfaction is paramount. Regardless of budget, timeline or contract requirements, Costello Construction has strived to recreate a client’s vision, exceeding expectations whenever possible.
