Common Ways Radon Enters Homes in Marshalltown, IA

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.

Foundation cracks

Small cracks in concrete foundations allow radon gas to seep into basements and lower levels.

Unsealed sump pits can act as direct entry points for radon from beneath the home.

Gaps where foundation walls meet floors are common radon pathways.

Openings around plumbing, electrical, and HVAC lines can allow radon to enter.

Homes with crawl spaces may experience radon buildup without proper sealing or ventilation.

Expansion joints and cracks in slab-on-grade homes can allow radon intrusion.

Understanding these entry points highlights why professional testing and properly designed mitigation systems are essential.

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!
