For over 100 years, a legacy has been forged at
Mowbray & Son, Inc / M&S Sheet Metal, Inc.

In 1916, Harry Mowbray and his partner Ernest Lewin, two England natives, opened a plumbing and heating business on Main Street in downtown Minot. In 1927, Ernest passed away, but the business continued under the name Lewin & Mowbray Plumbing. In 1935, the business emerged as Mowbray & Son Plumbing and Heating, Inc and Harry L. Mowbray joined his father.

Harry L. Mowbray became President of the company in 1954. In 1970, the main offices relocated and expanded to include M&S Sheet Metal Inc, Inc adding a HVAC/Sheet Metal Division. Two years later, Harry W. Mowbray joined the firm to become the third generation of master plumbers and furthered the tradition of the family business. Harry W. Mowbray took over as president in 1987. 

In 1990, Harry T. Mowbray began working with the family business while attending high school. Following high school, he attended North Dakota State University where he graduated with a B.A. in Mechanical Engineering. After eight years of training and apprenticeships, he became a fourth-generation master plumber. In 2013, Harry T. Mowbray continued the legacy by becoming the fourth generation President of Mowbray and Son, Inc. 

And the foundation of it all? A family that extends beyond just the Mowbray name. It includes all of the Mowbray & Son, Inc employees, loyal vendors, and clients. Without them, there would be no company.

Mowbray & Son, Inc’s success has been built on more than a family name. Our employees – the men and women that perform the high-quality work and service-are the lifeblood or our company. They are considered a crucial part of the Mowbray & Son, Inc family.

After 100 years of providing service to the Minot area, Mowbray and Son, Inc has become part of the foundation of our city and beyond. We intend to continue to build on that foundation for another 100+ years. From generation to generation, our legacy will continue to grow with the entire Mowbray and Son, Inc family.

This legacy is built on the following core values:

We look forward to hearing from you.
