Top Line Construction began serving the New Jersey construction market in 1991 when it was founded by Rui Castela. At its inception, the company employed approximately 15 people and was primarily a site concrete sub-contractor. Throughout the state, numerous general contractors utilized Top Line to perform concrete work on school, residential development, and commercial contracts. During this time, Top Line Construction earned a reputation as a sub-contractor who delivers quality work with dependability and value.

In 1999, Steven and Mark Castela joined with their father as owners and officers in the company. Steven had completed his B.S. in Finance from the University of Connecticut and Mark his B.S. in Construction Management from the Wentworth Institute of Technology. Rui’s experience combined with Steve and Mark’s shared drive for growth helped usher the company into a period of expansion. 

It was also at this point, the company decided to transition from a sub-contractor with commercial clientele to a general contractor in the public sector. Over the last two decades, Top Line Construction Corp. developed into a full-service Road and Site Construction Company serving various local and county agencies. Today the company specializes in Asphalt Paving, Milling, Grading, Excavation, Underground Utilities, and Site Concrete. Top Line Construction’s dedicated owners and employees continue to uphold the company’s reputation for quality and dependability by exceeding the expectations of their commercial and government clientele.
