Built on a Quarter-Century of Structural Building Work

Our founder brought more than two decades of basement and structural expertise to Eastern Idaho when he opened Eagle Rock Building, LLC. That depth of knowledge means you're working with someone who's seen every challenge a basement can throw—low ceilings, moisture concerns, awkward layouts—and knows how to solve them without cutting corners or inflating costs.

In a place like Idaho Falls, where winters are long and basements often sit empty, we see the potential in every square foot. From the older homes near the Snake River to newer builds in Ammon and Iona, we've helped families across the valley make the most of the space they already own.

We're proud to support homeowners and businesses across Idaho Falls, helping our community thrive one finished basement at a time.
