The Leading Plumbing Supply Company for the North Country
Our story began in July of 2021, when the Hynes family acquired the business from Winn Supply in Plattsburgh. With a strong foundation in the electrical supply industry since 1955, expanding into plumbing was a natural next step. This addition allows us to offer a complete supply chain, providing top-quality products and service for both plumbing and electrical needs.
At Hynes Plumbing Supply, we make it easy by offering both plumbing and electrical supplies under one roof. This convenient "one-stop" solution helps our customers save time and get everything they need for their projects in one place — whether it's plumbing, heating, HVAC, or electrical.
