Radon Mitigation in Ottumwa, IA

Keep Your Ottumwa Home or Business Safe from Radon

In Ottumwa, IA, safety starts with the air you breathe. Radon is a naturally occurring radioactive gas that seeps up from the soil and can enter homes and buildings through tiny openings in the foundation. Because it’s colorless, odorless, and tasteless, you may not even realize it’s there. But over time, high radon levels can pose serious health risks.

We help homeowners, schools, churches, and businesses across Ottumwa detect and reduce radon levels for cleaner, safer indoor air.

How Radon Enters Homes & Buildings

Cracks in basement floors or foundations

Even the smallest foundation cracks can become entry points for radon. As pressure builds in the soil beneath your home, the gas naturally looks for the path of least resistance. Hairline fractures that may seem harmless can allow radon to seep through continuously, especially in older Ottumwa homes with settling foundations or those built on clay-rich soil.

Openings created for water pipes, gas lines, or electrical wiring can also allow radon to enter. These gaps often expand slightly over time due to temperature changes or vibration, making them easy entry routes. Because these spaces connect the ground directly to your indoor air, sealing and mitigating them is an essential part of controlling radon levels.

Sump pump basins and floor drains are essentially open gateways to the soil below. As radon gas rises from the ground, it can flow freely through these pits and spread throughout your home. A properly installed radon mitigation system can safely vent this gas outside, preventing buildup in basements and lower levels.

Many homes in the Ottumwa area have crawl spaces or unfinished basements with exposed dirt floors or porous concrete. These areas allow radon to escape easily from the soil into the air inside your home. Sealing these surfaces and installing a sub-membrane depressurization system can drastically reduce radon infiltration.

While most radon enters through the soil, it can also dissolve in groundwater and be released when that water is used for showering, laundry, or cooking. Homes in rural areas around Ottumwa that rely on private wells may be more at risk. Testing both your air and water can ensure a full picture of your home’s radon exposure.

My wife and I recently purchased a new home that needed a radon mitigation system. Tim came highly recommended, and he was fantastic to work with—very down to earth, knowledgeable, and professional. He provided a great/fair quote for the system, and Tanner did an awesome job with the installation, taking the time to explain every step of the process. I highly recommend Milledge Construction!

I just purchased my first home this year and recently tested for radon gas, in which I found out it was a bit high. At the beginning of this week, I looked into getting a Radon Mitigation installed & requested an estimate from Milledge Construction, and I received a call back from Tim within 30 seconds. Tanner came and installed a new mitigation system this morning, and he was done within 2.5 hours. It looks great! I would 100% recommend them to others, and would be willing to hire them again for any construction needs. Thanks guys!
