Thank you for supporting your local businesses like us! Without you we would not still be here! 

Our story begins in 1929 when Mr. Cecil Maxfield opens his plumbing company at 14 N Howard in Croswell. Shortly thereafter in 1931, Mr. Francis Gardner buys his business and so begins Gardner Plumbing and Heating. Mr. Gardner works out of that little old building until 1949 when he temporarily moves his business to 9 Ward Street while he builds a new building. He moves into that in the early 50s and the address is 57 Ward Street, where we stand today. He operated his business for a total of 35 years. Our grandpa even worked as one of his apprentices. So, it's no surprise that around 1966 our grandparents, Bob and Bea Norman, would purchase his business and begin our family's journey. Proudly, in 1984, Gardner Plumbing & Heating would install one of Michigan's first closed loop geothermal systems. We would go on to successfully install hundreds of open and closed loop geothermal systems in our area over the next several decades. After almost 30 years in business, Grandpa Bob passed away in 1995. And by 1996 our father, Mark Cummings, would be running the family business. It would become known simply as GPH. That is until 2006 when we changed the business name to GeoMasters to stand apart and help better reflect our focus of Geothermal Heat Pump Systems. For almost 60 years, many members of our family have worked here and continue to work with us; Uncle Jerry Cummings, Uncle Phil Norman, Dave Anderson, Aunt Cindy Anderson (who passed away in 2025), and Jamie Kersten just to name a few. Upon our father's passing in 2017, both of his sons, Joel Cummings and Joseph Flint, took the reins and made this company third generation family owned and operated! It's been quite a ride. Together we hope to make those that came before us proud by continuing our family's legacy for many more decades.
