Specialty Carpentry

Duggan Contracting specializes in custom, complex finish carpentry projects in commercial, retail, hospitality, institutional, and residential markets.



Our residential team has become the cornerstone of the long-term, relationship-based service approach that we have always delivered to our clients.


Before and After

Duggan converted a 40’x60’ seventy year old barn on a limestone foundation to a high-end residence.

For more than 25 years, Duggan Contracting Corporation has been changing the way clients and customers experience construction.

From large-scale Design/Build commercial projects to the unique undertakings of custom Specialty Carpentry work, Duggan excels in transforming the seemingly impossible and unrealistic into a reality.

The Duggan team is comprised of a core group of 30+ construction professionals and 75–125 skilled professional tradesmen deployed at any given time.   Licensed and bonded in the majority of the United States and throughout Canada, we typically self-perform more than 200,000 man hours of carpentry work each year. Instilling our company values in each team member allows us to ensure each project’s success and guarantees our company’s integrity.

Adjacent to our company headquarters in St. Peters, Missouri, our sister company Fixture Concepts operates a 50,000 square foot manufacturing facility, offering clients a single source for casework/millwork services.  Our full-service firms provide high-quality millwork/casework manufacturing, and construction for Residential, Retail, Commercial, Educational, Hospitality, Healthcare, and Industrial markets.

Our full-service firm provides high-quality General Contracting Design Build services for Commercial and Residential construction, customized to suit each client’s needs.
