Building Trust, Confidence and Quality
Duffek Construction was founded with the simple vision of building great projects with and for amazing people and organizations. We opened our doors in 2017 to better serve Wisconsin small businesses and have quickly become one of Wisconsin’s fastest growing construction firms. In recognition of our growth and success, the company was named Newsmakers Up & Coming Firm of the Year for 2018 and recognized as a Future 50 company by BizTimes Media in 2022.
Family owned and operated, we take each job personally and take great pride in serving our clients. With over 100 years of experience between team members, Duffek Construction combines the maturity of a large organization with the cost structure and personal approach of a small firm. We believe that the prosperity of each project lies within its relationships. Our approach is collaborative, fostering communication among all team members. As your general contractor, we mark success not in the number of projects completed, but in the relationships forged with our clients, architects, engineers and subcontractors.
Duffek Construction is dedicated to making each project its best. As hardworking professionals, we believe in a culture of partnership and taking ownership in each project, while also remaining flexible to the unique vision your project requires.
