The average indoor radon concentration in Iowa is 8.5 pCi/L. More than six times the national average.

All of Iowa is located in Zone 1 indicating Iowans have a very high potential for elevated levels of radon gas.

Iowa leads the nation in the percent of homes over the 4 pCi/L level as well as the percent of homes over 20 pCi/L.

The Iowa Department of Public Health estimates that as many as 5 in 7 homes across Iowa have elevated levels.

An estimated 400 deaths per year in Iowa are caused by radon-induced lung cancer.

Don't delay, mitigate TODAY!


REP Radon has installed over 3000 radon mitigation systems, with customer service and quality top-of-mind during every installation. The company has been in business over a decade, working closely with homeowners and real estate agents.

Radon awareness continues to grow in the state of Iowa as levels throughout the state are at national highs. Determining if high levels of radon gas are present in your home is imperative for Iowans - so test today and call us to install a system if needed.

REP Radon offers free estimates for internal and external radon mitigation systems and guarantees each system for 5 years - with an option to extend the warranty to 10 (at an additional cost). With each radon mitigation system installation, REP Radon hires an independent state-certified third party testing company to ensure levels have been reduced to the appropriate levels.

Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas.


If your first test has a result between 4 and 8 pCi/L, you have the choice of testing again. If results are needed quickly, you can re-test with a short-term (2-7 days) device.


Radon mitigation is any process used to reduce radon gas concentrations in the breathing zones of occupied buildings.

Radon John does outstanding work, and is always ready to help out with any and all radon issues a home might have. Kelley and I have used him dozens of times for our Buyers and Sellers, and referred him to many other friends and fellow Realtors. His bids are always in line with the final price, and his work is second to none.
