Basement Finishing for Idaho Falls Homeowners

As the largest city in Eastern Idaho, Idaho Falls is experiencing rapid residential growth with new subdivisions in Ammon, north Idaho Falls, and along the Snake River corridor. The booming housing market means hundreds of new homes each year with unfinished basements waiting to be transformed.

Idaho Falls' clay-loam soil and high water table in the Snake River corridor mean moisture mitigation is critical before any basement finish. We always recommend a vapor barrier and interior drainage system for homes east of I-15.
