About Us

For over 35 years, D.L. Building Materials has been a leader in the distribution of drywall and other specialized building materials. We are Eastern Ontario and Western Québec’s largest gypsum supply dealer (GSD). Our inventory includes a broad array of building materials and a complete line of interior systems from gypsum, metal framing, suspended and acoustic ceilings, soundproofing, insulating products and specialized tools, etc.

We opened our doors for the first time in February 1988. D.L. started small, operating with only 2 trucks and 5 employees. Today, we continue to expand and innovate. We have more than 100 dedicated employees and over 30 trucks working hard to serve you better. We have three branches; at 760 rue de Vernon in Gatineau, 1-1300 Upper Canada Street in Ottawa and at 5 Terry Fox in Kingston, Ontario. Also, with over 120,000 square feet of warehouse and more than 196,000 square feet of yard space, we have become the largest drywall distributor in Eastern Ontario and Western Quebec. Our extensive truck fleet and experienced boom crane operators have made us experts in the delivery of specialized building materials. Thanks to our knowledgeable staff and superior customer service, we have become the industry’s supplier of choice in our market.

Additionally, we have successfully entered the commercial frames and doors market. Thanks to our technical knowledge, our exceptional delivery capabilities, and an energetic and affable staff, we have become a true leader in the industry in the Ottawa/Gatineau region.
