Welcome to Lunseth Plumbing and Heating Co.

Lunseth Plumbing and Heating Company is a locally owned and operated business which has been providing service in the Grand Forks area since 1935. In the over 80 years that Lunseth has been in business bidding mechanical work, we have grown and matured into one of the most recognized and respected mechanical contractors in the region. Our original focus was primarily plumbing; but we have evolved into a full service design-build mechanical contractor, with a Fire Protection division, and an Automated Controls division.
