Hartsig Supply Company is a family owned and operated business that first opened its doors in 1963.  Hartsig Supply started out as a small plumbing and well supply in Rochester Michigan.  Today Hartsig Supply is still growing.  We opened our new building in Auburn Hills in 2000.  Now, with the continuous growth of our area, Hartsig has become a plumbing, water well, heating, and water filtration supply as well.  We base our buisness on customer satisfaction.  We strive to help anyone out with any problem we can.  We look forward to helping you soon!
