Oskaloosa, IA is known for its welcoming neighborhoods, strong community pride, and historic homes—but like much of southern Iowa, it’s also an area where elevated radon levels are common. Radon is an invisible, odorless gas that seeps from the soil into homes and buildings, where it can accumulate to dangerous concentrations over time.
At Milledge Construction, we provide certified radon testing and mitigation services in Oskaloosa to help homeowners and business owners protect what matters most—their health and safety.

Radon forms naturally as uranium in the ground breaks down. In Oskaloosa and surrounding Mahaska County, the soil composition and foundation types of many local homes make them susceptible to radon entry. Even newer homes built with energy efficiency in mind can trap radon inside.
Long-term exposure to high radon levels is the second leading cause of lung cancer in the United States. That’s why routine radon testing is essential—especially if you’re buying, selling, or renovating a home in Oskaloosa.
If testing shows elevated radon levels, our team designs a custom mitigation system tailored to your property. Typical systems use a sub-slab depressurization method that vents radon safely outside before it can enter your living space.
Every system is:

Radon doesn’t need large openings to enter a structure. It can seep in through the smallest cracks or gaps. Because Oskaloosa and much of southern Iowa have naturally uranium-rich soil, radon gas can easily rise from the ground and find its way indoors.
Once it enters, the gas becomes trapped, building up to unhealthy concentrations without any smell, taste, or visual clues.
Here are some of the most common ways radon can enter your Oskaloosa home or business:
Even the hairline fractures that appear over time in concrete slabs and walls can create direct pathways for radon to rise from the soil below. As the gas seeps upward, it’s drawn into your home through natural air pressure differences.
Openings for pipes, wiring, or ductwork—even those sealed with caulk years ago—can allow steady radon entry. Homes in Oskaloosa with additions, remodels, or aging infrastructure are especially vulnerable as materials shift or settle.
These features, while helpful for managing water, can also act as open channels for radon gas. If your sump pit isn’t sealed properly, it can become one of the most direct entry points in your basement.
Many older homes in Oskaloosa still have dirt floors or unsealed crawl spaces. These porous surfaces make it easy for radon to seep through the ground and accumulate in lower levels, where it then moves into living areas.
Though less common, radon can dissolve into groundwater and release into the air when you shower, cook, or do laundry. If your home uses well water, testing both air and water may be recommended for a complete safety assessment.
Once inside, radon tends to build up in enclosed or poorly ventilated areas—especially during colder months when windows and doors are closed. Because it’s colorless and odorless, there’s no way to know your home’s radon level without professional testing. That’s why routine testing and mitigation are so important for maintaining healthy indoor air quality in Oskaloosa.
