The Bernhard Plumbing story began back in 1954 when Elmer Koepsell formed Koepsell Plumbing in Mayville, WI.
With small town values and a blue collar work ethic, a legacy of service, quality and customer satisfaction was born.

Over the years, our name has changed and our services have evolved.
But with decades of proven performance under our belts, our mission has been sound from the start:

Bernhard is dedicated to providing customers with the highest quality work and service we can offer.

From commercial and industrial and dairy operations to residential, water treatment and septic systems, today the Bernhard reputation continues to build by continuing to provide Mayville and the surrounding area with a wide range of expert plumbing services that surpass the industry standards.

Scott was very helpful by letting us borrow a tool that we didn’t have and our vendor couldn’t get in a reasonable time for our project. I made a call to Scott and explained what was going on and he was there to help anyway he could. When you have a business willing to help out another business that’s going above and beyond, and that is a 10 star rating. Thank you
