"While researching radon mitigation companies Rich was always on point in calling me back and sending email. This is what was the deciding factor in choosing which company we picked. I also called Rich back after we found out the exterior foundation had lead paint. He said they would take precautions to contain the dust from drilling the concrete. The other prospective companies had no idea on how to deal with this scenario and never called back when they said they would. The workers showed up a half hour early which was great and finished in 2 hours. The workers were very professional and cleaned up like they were never there. I asked if they could put it a certain location that was more convenient for us. No questions asked and they agreed that it would be a good spot. They caulked all piping in the basement so the system could be more effective in mitigating the radon. After installation they went over the system and answered any questions that I had. They guarantee the system and to get the levels below 4. The price was reasonable compared to other quotes. I would highly recommend them no questions asked."

"The service provided was Excellent! The radon level is now safe!! Joh and his team agreed to instal the system on one of the coldest days of the year in early Jan because I was worried and didn't want to wait for better weather. They were punctual, professional and personable. Joh helped pick the location for the unit so that it would be functional but also uninstrusive in the basement and on the outside of the house. Except for the soft whirring sound you would never know the system was there. It blends in so well on the outside that it just looks like another drain spout. I couldn't be more pleased. I would highly recommend them to anyone that wants to lower the radon in their house to a safe level."

"My husband and I had a very negative experience with a different inspection company a couple of years ago, so we were extremely cautious when searching for a new inspector. John Fleenor exceeded our expectations to such an extent that this is the second time we are utilizing his services, and we have no regrets whatsoever. We will hire him every time we need an inspector. He inspected the entire extent of the house carefully and reported every single issue. He discussed each issue with us, highlighting the more urgent ones. He was very patient with all our questions and remained available afterward for additional inquiries after we received the report. We also hired him for the radon control and pest control tests. The price was fair and totally worth it."

"I waited a month before getting a test kit I called and was told there was something wrong with the Angies list orders but that I would be receiving a kit soon. It wouldve ben nice if they called me to tell me that though. The test results were quick and on par with other radon test I had done locally."

FAQs for radon gas testing projects in Charleroi, PA

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.
