Us In A Nutshell

"Meeting your needs and exceeding your expectations since 1967"

Harmco is a family owned and operated company that started in 1967 in Penfield, NY in the basement of Harm and Arvilla Credit's home. Their mission was to serve contractors and the construction industry in a way that exceeded their predecessors in customer service. Now owned and operated by their sons, Harmco has expanded with two showroom locations, in Rochester, NY and Tonawanda, NY and has devoloped a clientele base that expands across Upstate NY. Still upholding the original values of the company, our sales representatives seek to build strong, individual relationships with each of our customers that will last a lifetime.
