Raleigh-based Clancy & Theys marks 75th year in construction industry

Raleigh-based Clancy & Theys Construction has reason to to celebrate – the company started by two brothers-in-law reached a milestone in January: 75 years in the industry.

The privately-owned, family-run construction firm plans a yearlong celebration of both internal and external events.

“Three-quarters of a century in business is quite the achievement, and we are beyond excited to celebrate this success throughout the year,” says Baker Glasgow, president, in a company release. “We have built a lasting legacy by forming  partnerships with our clients, design and construction partners, and the communities in which we work. While  our industry is ever-changing, our family-centered values are unwavering. They are engrained in all we do and the foundation for the Clancy Way.”  

E.I. Clancy and John Theys started the company in 1949 during the post World War II construction boom. The brothers-in-law were “guided by fairness, integrity, and an eager desire to contribute to others’ success.”  

Clancy & Theys built the Holy Name of Jesus Cathedral in Raleigh in 2017. The 44,000 sq ft cruciform-shaped cathedral has a seating capacity of 2,000.

Over the past 75 years, the company has become a cornerstone of the Southeast’s construction market, nationally ranking among the top builders, green contractors and design-build contractors. It topped $1 billion in revenue for the first time in 2023. Revenue in 2022 was $846 million.

“What started as one office with a handful of employees has grown into six offices with nearly 500  employees,” says Glasgow.

Clancy & Theys also has offices in Wilmington and Charlotte, Newport News, Virginia, Orlando, Florida, and Greenville, South Carolina, with the latter opened in 2023. The Wilmington office celebrates its 40th year and the Newport News office its 35th year in 2024.
