Radon is an invisible danger that many property owners in Ames may not realize is present. This naturally occurring radioactive gas seeps out of the soil and into buildings through cracks, gaps, and other openings in the foundation.
Because radon has no color, smell, or taste, the only way to know if your home or business is affected is through professional testing.
At Milledge Construction, we specialize in radon testing, mitigation, and monitoring throughout Ames and Story County.

Iowa consistently ranks among the states with the highest radon levels in the country, and Ames is no exception. The soil and rock formations in central Iowa make radon accumulation more likely, and according to state health data, the majority of Iowa homes test above the EPA’s recommended action level of 4.0 pCi/L.
Whether you own a home near Iowa State University, manage an apartment complex in north Ames, or operate a business downtown, radon testing is critical to protecting the people inside your building.

Radon gas doesn’t need a large opening to find its way indoors. Because it rises naturally from the soil, it only takes a small crack or gap for it to slip inside. Once indoors, it gets trapped and begins to build up, often without any signs until testing is done. Ames homes, schools, and businesses can be affected no matter their age or construction style.
Here are some of the most common ways radon enters:
Even the smallest fracture in a foundation or basement slab can act like a doorway for radon. As the soil underneath shifts with freeze-thaw cycles or natural settling, these cracks can expand, allowing more gas to seep inside undetected.
Every pipe, wire, or conduit that enters your home needs a hole through the foundation or wall. If those openings aren’t tightly sealed, radon can ride in alongside the utilities. What looks like a harmless gap around a pipe can actually be a significant source of exposure.
Basements with sump pits or homes with vented crawl spaces are particularly vulnerable. These areas often sit directly on top of bare soil, which makes it easy for radon to escape upward into your living areas. Without a cover or mitigation system, these spaces can become major entry points.
Radon doesn’t just enter through floors—it can travel inside the cavities of block walls or move with the air through ducts and vents. Once inside these hidden pathways, the gas can spread throughout the entire house rather than staying in one isolated area.
Private wells can naturally draw radon from underground aquifers. When this water is put to use, especially during hot showers or while running dishwashers, the agitation releases the gas into the air. Over time, repeated exposure to radon released from water can raise overall indoor levels.
If elevated radon levels are found, Milledge Construction designs and installs custom mitigation systems tailored to your building’s layout.
