Our Customers Are Our Best Ambassadors.

Our xc ski club hired Cornerstone to build a new 1400 square foot insulated steel shop building for our grooming equipment. Dennis was great to work with, flexible with volunteers on saving money where we could, and finished the building well before expected and the whole experience was painless, from initial contact to final product.

Great company to do business with

Dennis and his staff did a great job on my shop. The attention to detail by his foreman was really comforting to know things were built under quality conditions. Dennis stuck to the quote he gave me. I gained a new relationship because Dennis is easy going, down to earth and open with dialogue. I recommend him.

The Cornerstone team was efficient and incredibly responsive in completing our home renovation needs. They were able to get our walls knocked out and a weight bearing beam placed within a day plus I came home to a clean home once they had finished. Highly recommend!

Communication was great, professional, fast and clean work! Could not complain! Great work guys.

Great people to work with. They do the job competently, promptly, and get along with the neighbors while doing it. Dennis is flexible and communicates well with his customers. Highly recommended.

If you are looking for someone with attention to detail, solid relationships, and the ability to deliver a project on time Dennis is the contractor you want to work with! With a wealth of experience building in Western Montana, Dennis is a great contractor to work with.

8. We weren’t sure how Cornerstone Steel (being a custom home builder) would do with a commercial build. However, we were pleased from beginning to end with the quality of work and the end result. Cornerstone did an excellent job on our new commercial building. They stayed within our budget and in some areas even came in less than budget.

Cornerstone has an excellent group of partners and are well worth the consideration.
