Guelph-Orangeville Building Supply has grown over three generations and three decades, with a focus on high standards, quality products, knowledgeable staff, and a "customer first" philosophy. Bert Niezen, owner of Orangeville Building Supply began the family business in 1991 and the Niezen family opened the doors of Guelph Building Supply in 2004.

Customer service remains our number one value, and is matched up by superior products, reputable suppliers, and an incredible staff. It's a winning business model that allows both locations to maintain an elevated reputation throughout Dufferin/Wellington County and beyond.
