"We had one little unanticipated issue and they handled it perfectly. He was by far the most reasonable quote I received and the quality was great. I thought he was very professional and very knowledgeable about radon. Before this experience I didn't know very much about radon now I know more about the importance of testing, and the safety of my home and family because of him."

"I worked with Pam throughout the entire experience. She was wonderful. She contacted me quickly to schedule an appointment and also scheduled radon testing on my behalf. We had to reschedule due to a snow storm, but she was quick to contact me and arrange a new day. On the day of the appointment, she showed up on time. We spent a few hours at the house while she inspected it. She pointed out a few issues here and there. As soon to be first time homeowner, I really appreciated this. She sent the inspection report the following day. It included in depth details and pictures.

"It went well. A guy came out and did a free basement inspection. We had some water intrusion that I am correcting myself but I wanted a pro to come out and make sure the sill and other foundation parts were still in good shape. He came out and answered all of my questions in the inspection, and explained that the sill plate was still in good shape and that no repairs were needed. That was honest of him and incredibly helpful information to know. He did a thorough inspection and was polite enough to answer all of my questions. Very professional!"

FAQs for radon gas testing projects in Indianapolis, IN

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.
