At the heart of Finn Construction is a family that has spent nearly three decades turning dreams into homes. Founded by Corey and Haley Finn, this family-owned company has grown into one of the most trusted custom home builders in Eastern Idaho and Western Wyoming — known for its honesty, craftsmanship, and personal touch.


Corey began his career as a licensed general contractor over 27 years ago, learning every trade from the ground up. His commitment to integrity and quality has shaped Finn Construction into what it is today, a respected residential general contractor that clients rely on for precision, communication, and results.


Haley brings warmth, organization, and a deep sense of care to every project. She’s often the first voice clients hear - guiding them through the process, coordinating details, and making sure every experience feels personal and stress-free. Together, Corey and Haley have built not only homes, but lasting relationships with families across the region.


Now, the next generation of Finns is stepping in to carry on the legacy. Their sons have joined the company, learning the craft and values that have made Finn Construction a trusted name among local home builders. With the Finns, you don’t just hire a custom builder, you partner with a family that’s deeply rooted in this community, raising their own family here and building for the families who call it home.


Every project is personal to the Finns. From the first handshake to the final walkthrough, you’ll work directly with a member of the family - not a sales rep or a distant project manager. It’s this level of care and involvement that makes the experience of working with Finn Construction unlike any other house contractor or luxury home builder in the region.


At the end of the day, the Finn name stands for something simple: honesty, craftsmanship, and the belief that quality over quantity always wins. When you build with the Finn family, you’re not just getting a house — you’re getting a home built by people who truly care.

We loved having Corey and his crew build our house! The process from start to finish was no easy task, but we were happy to work with such great people. All our concerns and needs were addressed and we were made to feel comfortable throughout. We received a truly custom house that was exactly what we asked for. I will never move because I love my house so much, but I will use Corey and his crew again when we were ready to expand and build a shop.

We love our new home!! Finn Construction LLC is amazing and went above and beyond when building our home! Corey and his crew are amazing and are perfectionists! Anytime we had a question or thought there was an issue, Corey was ahead of us and had already addressed the issue and it was in the process of being corrected.
