Professional Radon Reduction for Coralville Properties

Coralville is a vibrant city of approximately 22,000 residents in Johnson County, Iowa, situated directly adjacent to Iowa City and connected to the Cedar Rapids metro by the Interstate 380 corridor. Home to the Iowa River Landing development, the Coralville Marriott Hotel and Conference Center, and the renowned Coral Ridge Mall, Coralville has grown into a major commercial and residential hub in the Iowa City-Cedar Rapids region. The city's residential neighborhoods range from established areas near the old town center and along Fifth Street to the expansive newer developments on the west side near Coral Ridge Avenue and Holiday Road. Across all of these neighborhoods, radon is a persistent and serious concern — Johnson County is classified as EPA Zone 1, where predicted indoor radon levels average above 4.0 pCi/L, and testing consistently shows that a large percentage of Coralville homes exceed this threshold.

Coralville's position in the Iowa River valley means the city's underlying geology includes a mix of alluvial deposits, glacial till, and carbonate bedrock — all of which contribute to radon production and transport. The Iowa River itself has carved through layers of limestone and shale, leaving fractured bedrock that serves as an efficient conduit for radon gas moving from deep soil to the surface. Homes built near the river and in lower-elevation areas of Coralville may be particularly susceptible, although radon risk is not limited to any single neighborhood or elevation. Our mitigation team has worked extensively throughout Coralville and understands the variety of foundation types and soil conditions present in the city. We design every system to match the specific needs of your property, whether you have a poured-concrete basement, a block-wall foundation, a slab-on-grade construction, or a combination of foundation types across additions and original construction.

Many Coralville homeowners first encounter radon as part of a real estate transaction, when a buyer requests a radon test as a condition of sale. If the test reveals levels at or above 4.0 pCi/L, a mitigation system is typically required to close the deal. Our experienced team can install a complete active soil depressurization system quickly — most installations are finished within a single day — ensuring that your home sale proceeds on schedule. But radon mitigation is not just a real estate concern. Long-term exposure to elevated radon is the second leading cause of lung cancer in the United States, responsible for an estimated 21,000 deaths annually. Every Coralville home should be tested, and any home with elevated levels should be mitigated, regardless of whether a sale is involved.

We serve all of Coralville and the broader Johnson County area including Iowa City, North Liberty, Solon, and Tiffin, as well as Linn County communities to the north such as Cedar Rapids, Marion, and Hiawatha. Our service area along the I-380 corridor allows us to respond quickly to Coralville appointments. We are licensed and insured, and every mitigation system we install includes a post-installation radon test to document that levels have been successfully reduced. We also offer radon fan replacement and maintenance services for existing systems that may need attention.
