     Bob Koster Sr. founded K&S Plumbing in 1982, and he had no idea it would grow into a commercial plumbing company spanning three generations. Once Bob Sr. retired in 1997, his sons Bob Jr. and Jack took over the family business. Today, the company is managed by Brian Koster and Ben Koster with Robert Koster overseeing everything. Since we are a family-owned company, you can trust us for some of the best plumbing work in the area.

     

Over 35 years of experience has taught us that the customer is always right. We are accredited by the Better Business Bureau, which means you can count on us for quality customer service. While our office and warehouse are located in Grand Rapids, we are proud to serve commercial building owners throughout southern and west Michigan.

 

   Our plumbers offer a full range of plumbing services for your industrial or commercial building. In fact, we have been a preferred plumber for McDonald’s restaurants for over 15 years!
