Sletten Construction Company opened back in 1928 in Great Falls, Montana. Since that time, we have literally helped build this great state from the ground up. We are considered to be one of the oldest, if not the oldest, most respected and capable construction companies Montana has ever known. Today, a LEED certified, design and build construction company, our projects have included building in categories such as school, water treatment & reclamation, detention center, jail, medical, healthcare, bridge, interchange, dam, creek improvements, theater, performing arts, emergency, tech, trestle, lab, office building, courthouse, judicial, campus, and more. The odds are, if you have ever traveled through or lived in Montana, you have more than likely traveled over one of the many bridges or interchanges we’ve built and have been in one or more of the facilities we have constructed.

Sletten - The Top Choice in the Western States

Sletten currently has locations in Great Falls, Missoula and Billings MT. We also have locations in other states throughout the Southwest. Sletten is quick to become the construction company of choice for nearly all of our clients. It’s simply that we are experts in what we do, we provide exceptional work, full services and the fact that being on-budget and on-time is a standard operating procedure for us. There aren’t many construction companies in Montana, or anywhere in the Southwest that can truthfully say such things. It's just how we’ve always done it. Nobody likes surprises when it comes to their construction projects. We don’t and you don’t either.

Why Choose a 100% Employee Owned Construction Company for Your Montana Building Project?

Our company structure allows us to take a personal interest in each project we complete. Sletten empowers each employee-owner to make an impact and holds them accountable to perform at their very best. It is important for us to meet and exceed our client’s expectations.

Our Construction Process

Even with our depth of experience in completing construction projects, we take a customized approach to every single one. Since each structure is unique, our team starts with an initial consultation to get a solid understanding of the Owner’s requirements, goals, and budget.
