"The company did an excellent job: they showed up on time (for both the initial estimate and to perform the work), were professional and courteous and cleaned up upon completing the project. I am already a repeat customer and would certainly use this company again in the future."

"I recently moved into my home. There were very few issues listed by the original inspector. Everything started going wrong in my home. I was despondent and felt unsafe. I called Troy. He took his time with the inspection, explaining everything to me along the way. He explained the priorities and made me feel safe and secure. After the repairs are made, I will call him back to inspect the repairs. He cares and I trust him."

"During a heat wave in August with temps in the 90s, our air conditioner went out. We had a technician come out on Monday morning who recommended replacement of our unit. I purchased the Enhanced Service Plan for $250 which would provide two annual maintenance services. I was told that the office would call us back with an estimate. Near the end of the day, we called and asked for an estimate and were told we would receive one in the morning. We waited until after noon on Tuesday to make a decision on which company to go with after receiving 2 other estimates. Given the heat wave and having not received an estimate from Mark IV at that time, we decided to go with a company. I emailed asking if I could receive a refund on the Enhanced Service Plan due to the untimely estimate and the company we ended up going with requiring us to use their service for the first year for warranty purposes. I never received a reply or a refund."

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.
