Altoona, Iowa, is a vibrant community known for its family-friendly atmosphere and growing neighborhoods. However, beneath the surface, there’s an invisible threat that many homeowners may not be aware of—radon gas.
As the leading cause of lung cancer among non-smokers, radon poses a significant health risk. In fact, Iowa has the highest average radon levels in the United States, with nearly 70% of homes testing above the EPA’s recommended action level of 4.0 pCi/L.

Radon is a naturally occurring radioactive gas that seeps into homes through cracks in foundations, gaps around pipes, and other openings. Because it’s colorless, odorless, and tasteless, the only way to detect radon is through professional radon testing. Without proper mitigation, radon levels can accumulate to dangerous concentrations, increasing the risk of serious health issues.
In Altoona, homes are particularly susceptible due to the area’s geology and construction practices. Whether you’re buying a new home, renovating an existing one, or simply seeking peace of mind, regular radon testing is essential.
Radon is an invisible, odorless gas that forms naturally in the ground as uranium in soil and rock breaks down. Because it’s part of Iowa’s natural geology, radon can move upward through the soil and slip into homes, schools, and businesses through tiny cracks or openings in the foundation. Once inside, it can accumulate to unsafe levels, especially in basements and lower floors.
What makes radon especially dangerous is that it’s radioactive. When breathed over time, these particles can damage lung tissue and increase the risk of lung cancer. In fact, radon exposure is the second leading cause of lung cancer in the U.S., and Iowa ranks among the highest states for average radon levels.
At Milledge Construction, we take this threat seriously. Our certified professionals provide precise testing and effective mitigation solutions to keep Altoona homes and workplaces safe, healthy, and compliant with EPA guidelines.

Radon forms naturally underground as uranium breaks down in the soil—a process that happens everywhere in Iowa. The gas rises through the ground and, if given the chance, can slip inside through even the smallest openings in your home’s foundation. Once indoors, it becomes trapped, allowing levels to build up over time, especially in basements and lower levels where airflow is limited.
No home is immune to radon. Whether you live in a brand-new build or a century-old farmhouse, the gas can find a path inside.
Here are some of the most common entry points we see during inspections across Iowa homes and businesses:
Even hairline cracks in concrete slabs or basement walls can provide an easy path for radon to move from the soil into your home.
The seams where different parts of your foundation meet—such as walls and floors—often leave small gaps that allow radon to leak in over time.
Openings made for pipes, wiring, and utility lines create pathways for radon to follow the same route as air and moisture from the soil.
These below-grade spaces often have direct contact with the soil, making them prime areas for radon infiltration if not properly sealed or vented.
Empty spaces within walls can act like conduits, spreading radon from the lower parts of your home to living spaces above.
Radon can dissolve into groundwater and be released into the air when you use faucets, showers, or washing machines.
Brick, block, and mortar can allow slow movement of soil gases through capillary action, particularly in older structures.
Negative air pressure inside your home—caused by HVAC systems or exhaust fans—can actually pull radon in from the ground through small gaps.
Where the floor slab meets the foundation wall, tiny separations or settling can open enough space for radon to enter and spread.
If you need a one-time radon test, a second opinion before buying a home, or a complete radon mitigation system for your property, we deliver clear results, honest recommendations, and expert installation every time.
