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, Koval Building and Plumbing Supply was founded by John Koval Sr in 1963. Since then, we’ve grown exponentially to four locations, including Granville, Morgantown, and two in Uniontown. Within each of these stores, you’ll find a wide range of nationally recognized plumbing, heating, kitchen, kitchen remodel, hot tub and bath products.Why not come and see for yourself?
