Serving West Virginia and Pennsylvania

Our Story

We invite you to visit our family-owned and operated business that’s committed to the motto: “Quality products and service after the sale.” From our early, humble beginnings in the small town of Granville, where old dilapidated buildings were torn down and sold off for scrap, Koval Building and Plumbing Supply was founded by John Koval Sr in 1963. Since then, we’ve grown exponentially to three locations, including Granville, Morgantown, and Uniontown. Within each of these stores, you’ll find a wide range of nationally recognized plumbing, heating, kitchen, hot tub and bath products. Why not come and see for yourself? And while you’re here, say hello to Stephen and Jackie Koval, they’d love to meet you!
