"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

"I called American Inspections on a Tuesday, left them a message, and told them I needed an inspection within a week. I received a phone call that day and Steve was able to squeeze me into his schedule. He put in the radon test on Friday and to read it on Monday for our appointment. The appointment was at 4pm and he was already inside and working when I arrived on time. The appointment lasted about 2.5 hours. Steve was very thorough in every room. He explained everything he was looking for in an older home and asked me if I had questions. He was knowledgeable about the history of the houses built in the neighborhood. He gave me suggestions about improving the safety of the house when I asked. He was very nice and personable. I would definitely recommend his service to anyone. <br />"

"Andrew did the whole home inspection and then spent about 2 hours with me explaining each aspect of the report in depth. He also took me around the property and answered any additional questions I had. Andrew was professional and courteous. He charged a fair price for his work. This inspection was a good investment. <br />"

"<p>David Manley came to our home and assessed the need for a radon system.  We had previously tested our home ourselves and the results were high.  He was very personable and professional and presented his product carefully.  </p> <p>The system was installed in early March.  After 24 hours, our home was tested.  The result was below the US EPA action level for indoor radon, but not well below.  </p> <p>We called David and he too was not satisfied with the result..  He and his crew came back within a few days and installed a second vent pipe.  This was done at no additional cost to us and the level is now well below 4.0. </p> <p>The company was very careful during installation to vacuum constantly so there was no dust.  There installation work was neatly done. </p> <p>This is an honest company and one with whom we would work again. .  </p> <br />"

FAQs for radon gas testing projects in Iowa City, IA

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
