Our History

In 1979 James X. Clemens, landed his first construction job – the renovation of a small office. With no hired staff, Mr. Clemens had to perform almost all the work himself. The final outcome was a success. From the success of that single job, Mr. Clemens was able to hire a few employees and founded his own company. His innate vigilance and determination saw him through many long hours. But the payoff was in his ability to keep winning bigger jobs with more prestigious clients. In addition, his skill at hiring the best people for the job would pay off immediately. Within the first year of starting his company, Mr. Clemens achieved his first major accomplishment by generating over 1 million dollars in sales.

Founded by James X. Clemens and headquartered in Philadelphia since 1979, Clemens Construction Company launched as a full-service commercial construction company specializing in retail banking and high-end corporate office projects. We have since evolved into one of the Northeast’s most trusted general contractors, offering both renovation and new building construction in numerous categories including multi-family, hospitality, pharmaceutical, telecommunications and historical renovation. Over the past 40 years, we’ve completed thousands of projects across 9 states, spanning from New York to Washington, D.C. to Ohio, resulting in what is now the largest geographic “footprint” of work of any mid-sized general contractor in the Northeast.

Teamwork + Collaboration

We view our client relationships as a true partnership with a common goal – achieving full vision of the project down to the last detail. We are here to solve problems big and small, from pre-construction and planning phases all the way to ribbon-cutting and beyond.
