Our Roots

Our story begins 48 years ago, in 1976 with our founder, Denis Lefebvre, and his vision to build the best possible Drywall Firm in Ottawa to meet the growing market. Equipped with the knowledge gained from his early construction experience with his father, Roland Lefebvre, he launched his first company.

Very quickly, the company’s high commitment to quality, fine craftsmanship and a strong work ethic was noticed by Ottawa’s general contractor’s community. Our company has been a partner in the creation of many of this city’s landmark buildings – The National Gallery of Canada, The Canadian Museum of Civilization and many of the finest examples of residential, high-rise residential, commercial, cultural and institutional buildings in Ontario.


Korban, a family business, confidently entrusts its future to Patrick Lefebvre, who has imbibed the wisdom of his father, Denis Lefebvre, founder of the company. Their enduring commitment to exceptional service and quality products remains unwavering. With a highly skilled team in the fields of construction management, interior design and drywall, we pride ourselves on our strong partnerships with Ottawa’s business community and our contributions to the city’s vital developments .

Together with leading architects and designers, we precisely carry out various projects, including complex interior designs. Our expertise is demonstrated in critical engineering projects, under controlled conditions, meeting rigorous specifications. We work skillfully in challenging environments, ensuring business continuity and security, even around sensitive equipment and complex technology networks. Korban continues to set industry standards.
