Radon Testing & Mitigation in Mason City, IA

Protecting Your Home and Business from Invisible Risks

At Milledge Construction, we specialize in professional radon testing and mitigation services throughout Mason City, IA.

Whether you’re a lifelong homeowner near East Park or a small business owner operating in downtown Mason City, safeguarding your indoor air quality should be a top priority, especially in a region known for higher radon levels.

Radon is an odorless, invisible gas that seeps into homes and buildings through the soil. It’s the second leading cause of lung cancer in the U.S. and is particularly prevalent in northern Iowa due to the region’s glacial soil composition.

That’s why we offer precise testing and proven mitigation systems tailored to the needs of Mason City residents.

Why Radon Testing Matters in Mason City

Many properties in Mason City were built before modern radon codes were in place, and even newer homes aren’t immune. Because radon is colorless and odorless, the only way to know your exposure level is through testing.

Our team uses industry-leading equipment to perform accurate, efficient radon tests in both residential and commercial buildings.

Whether you live in the River Heights neighborhood or manage a commercial space near MercyOne North Iowa, we’re here to help identify potential radon threats early, before they become a health risk.

Common Ways Radon Enters Buildings

Cracks in foundation walls and floors

Even minor foundation cracks can create direct pathways for radon gas to enter from the soil below.

Unsealed sump pits and exposed crawlspaces act like open doors for radon.

Areas where pipes and cables enter the home, or where foundation walls meet, often have small gaps ideal for radon intrusion.

These subtle spaces, common in basements or slab-on-grade homes, allow radon to pool silently indoors.

Poorly sealed HVAC systems can pull radon into your home, spreading it throughout your living spaces.

Moisture in porous building materials can help draw radon upward from the soil into the structure.

In rural areas around Mason City, radon can enter your home through well water, especially when used in showers or washing machines.

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!
