Proudly serving Northwest Montana since 2007

Thank you for choosing Reum Custom Building for all of your new construction and remodeling needs. We have been proudly serving the residents of the Flathead and Mission Valleys in beautiful Northwest Montana for 13 years.

Although Montana is beautiful, it can bring extreme weather conditions. Regardless, James and his team will work through it, keeping your project on schedule.

Whether you are looking for rustic elegance or an industrial finish, your project will receive the utmost care and professionalism that our customers have come to expect. 

Why choose Reum Custom Building?

James is not your typical general contractor. With a majority of our specialty trades being in house, we are able to provide our homeowners with a high quality finish and affordable price point. 

One of Reum Custom Building's projects was feature in the March 2014 issue of Log Cabin Homes focusing on our custom half log siding. 

We are members of the Flathead Building Association, Montana Building and Industry Association, and National Association of Home Builders.
