"I recently purchased a foreclosure which tested with elevated levels of Radon during the home inspection. There were some companies that offered significantly less expensive solutions, but not impressed as their bids provided no information and would have been out the basement and up the side of the home which does not look very nice. Midwest Radom came out and we found a route out the basement, through the garage up through unfinished attic space, and out the roof which allowed the exit pipe to come out the roof on the backside of the home. This was actually decided upon during the initial install when we discovered the original solution presented by the estimator was not workable. They were not going to put firestop collars because I live in MO and "that is not required by code" even though I had discussed it with the owner when I first called, because I had done my homework and learned they are important and asked for them. They were going to charge more, but ended up honoring their original offer which I appreciate and feel is reasonable for some 4" PVC pipe, 2 X 2 plastic sheet, 4" radon fan, vacuum gauge, 2 fire collars, and 1 roof penetration flashing with 3-4 hours of labor with 2 technicians. They had to do a penetration from the basement to the garage and from the garage to the attic space. They pulled from an existing outlet for power for the fan and a final penetration out the roof. It took 2 trips to complete the work because it was raining or snowing the first trip they made. They charged $1005.00 for the job and took less than 4 hours to complete. They also performed a follow-up test which showed a decrease in Radon levels in the safe range. I highly recommend Midwest Radon because their price was fair for a good job done to my expectations based on industry best practices which are higher than what the state of Missouri presently requires."

"Terrific - huge relief! Wish now that I had not procrastinated getting an estimate. I simply had no time previously and now that I had 2 weeks' time off for the Christmas holiday season, decided I would undertake what I assumed would be the unpleasant task of researching companies, securing an estimate, and beginning to face what I was sure was a significant mold problem. I have a 58 year-old home (which we love and hope to remain in forever - as we moved here for the ranch layout and hardwoods - perfect for 2 family members in wheelchairs). Unfortunately, our beautiful but older home has old, corroding copper pipes in the walls - and pipe in the wall beneath kitchen sink had a few leaks that leaked over time into the wall. After plumbers cut open sheetrock to repair sections of leaking copper pipe (twice) ...as the home warranty plan we have is great and covers removal and replacement of corroded sections of copper pipe for a small co-pay (but only covers removal & replacement of a few inches of pipe around the corroded area rather than covering replacement of the entire 5 ft run of pipe) and we've had a couple sections of pipe in the wall under sink replaced. Each time a section of pipe was replaced, plumbers opened up more sheet rock in the area to expose the pipe - which also exposed mold on a 2 x 4 and insulation in that area. Plumbers had also quoted cost of replacing the entire run of pipe - just in case I ever decide to replace my lower kitchen cabinets, noting that would be a good time to get rid of the entire run of copper pipe. So - back to the mold issue I had avoided for so long, assuming it would be expensive. After getting a few names of mold remediation companies from Angie's List, I quickly read the reviews & noticed several reviews for Advanta Clean of Kansas City mentioned this was not a company looking to secure work if professional assistance was not truly needed and often simply provide a recommendation and advice on how the homeowner can take care of their smaller-than-anticipated work on their own and avoid costly repairs. Reading the reviews provided some relief, and I hoped to get a visit and free estimate from Kevin, as reviews of him were really good. What I actually experienced when Kevin visited our home can't easily be described. My worries and concerns were immediately alleviated. Kevin was highly professional, describing national guidelines recommendations, noting our issue was less substantial than we had thought, and provided 3 different approaches that could be taken - detailing each. The first approach (and one he recommended) was free - simply cleaning up the area ourselves with vinegar and allow it to dry well, along with using a dehumidifier in the house (as humidity was reading high). The second approach (if uncomfortable cleaning the small area of mold on our own) was in the $350 range plus cost for asbestos testing (necessary in a home of our age to ensure crews would be safe while completing repairs) with asbestos testing through an independent company of our choosing (though Kevin could provide info if needed) running ~$400 (this entire second approach was deemed an unnecessary but available option by Kevin), and the third approach was ~$1200 (which covered a significant amount of work...removing lower kitchen cabinets, all sheetrock & insulation behind them, cleaning up the area and using HEPA fans) which Kevin noted was an 'aggressive' but available approach - should we prefer that. I had feared hearing $5k to $6k - so had done nothing for far too long. I wish I had called earlier!! I now have a plan that costs me nothing for now - which I feel safe with (priceless). And, since I already intended to pull out & replace lower kitchen cabinets after saving up a bit (& also replace the 5 ft run of copper pipe in the wall that started all these issues) I now have a solid idea of what it will cost to do the level of agressive mold remediation that I prefer to do (pulling out/checking/replacing insulation near the area) - once I'm ready to be without a functioning kitchen for a bit. Meanwhile, I am very comfortable managing the small area of visible mold on my own. And, will definitely be calling Kevin at AdvantaClean whenever I get around to replacing my lower kitchen cabinets, to do the level of unnecessary but precautionary checking I'd prefer to do. An outstanding, highly professional company that I will be using in the future, and would recommend to friends and family. THANKS!!"

"I needed to have a radon mitigation system installed in my elderly mother's house. I did not have time to personally observe the process, so I contacted a few companies on Angie's list that had high ratings. Tom Manz reached out to me within a day of contact and gained my confidence due to his thorough explanation of the process and his punctuality. I entrusted Tom to my mother's house where he conducted a site survey and provided me a written e-mail estimate the same day. I authorized the work and scheduled the installation a few days later. Tom installed the system within the timeframe and cost he estimated. He tested the radon levels and provided me all documents by e-mail to support the effectiveness of the system. In turn I was able to provide these documents to the buyers finance company with ease. Tom even deferred final payment until the closing of the house which was unexpected for me. In summary, I entrusted Tom with the keys to my elderly mother's house and he did exactly what he said he would do. I have never met Tom in person, but appreciate that he installed this system and I was worry free during the entire process. Thanks Tom. <br />"

"Our fan went bad after 3 years. We had Certified Radon (original installers) come out to replace our fan. Something was not properly sealed and moisture trips the circuit. Now that fan trips the circuit breaker, my sump pump is on the same circuit. They will not come and fix their install problem for over a month. The only advice was to TURN OFF MY FAN for the 5 week wait, so that my sump pump will work. Disappointed."

"Jerrod completed a total home inspection for us. The inspection was very thorough, taking about 3 hours and he emailed us a 30 page inspection report the next morning. Our home is 11 years old and we wanted to get a handle on needed maintenance. He also provided a summary prioritizing the repairs needed. So far we had one question that we emailed him about, and he responded within 30 minutes. The $300 we spent was well worth it, as he also spotted a gas smell outside our home near the gas meter and had me call the gas company. They came out within 15 minutes and fixed the problem immediately. Jerrod was very professional and courteous and I would recommend him to anyone needing a home inspection."

FAQs for radon gas testing projects in Liberty, MO

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.
