Highest quality
service since 1964

In 1964, Allan Ward started Guaranteed Supply Company with a simple goal - To provide quality, specialty products to the construction trades. By the time the company launched, Mr. Ward had years of experience in the construction industry under his belt. What he felt was lacking, however, was a supplier who could promote specialty items to the industry and deliver on those services and items in a caring and efficient manner. Above all, Allan wanted to tend to the customer first, delivering the warm and familiar feel of a neighborhood store to the ever-growing construction industry.
