"Anthony with ALO Radon came out and did a CRM radon test for us. He was very knowledgable about radon and patient enough to answer all my questions. I recommend these guys to anyone needing radon work done. Why is there no RADON category? I will have to file this under HOME INSPECTION I guess."

"<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 />"

"It?s advantageous to have the expert in the field do your work!   We bought a 40 year old ranch style house. During the negotiations we had it inspected and the radon tests were above the national limits, so we specified it be remedied. The selling realtor countered with  something like ?here?s $1000 off the price; call our usual guy - he can fix it for that?.  That guy didn?t reply to our voice mails.  I looked at radon mitigation contractors in Angie?s List and discovered one of them, Dr. Leo Moorman, is the national expert who has done a lot of the academic research and published in the scientific literature on the topic.  I read a couple of his studies and discovered he has not only developed the mathematical models for determining optimal mitigation configurations for a given building but he has combined that with at least 1.5 decades of actual installing experience on more than 1500 buildings (in addition to his regular job as an Assistant Professor of Physics).  He?s the certified instructor who teaches other contractors how to do it right.  Leo was great to work with.  He inspected our home and explained his approach to the problem.  There was uncertainty on whether the space under the basement concrete floor was one whole space of dirt and air that could be vented by one hole in the floor (the realtor?s assumption), or there could be foundation footings that divides that space into multiple spaces requiring multiple holes and pipes to vent each of those spaces.  He drilled small holes in well-chosen places and made pressure and flow measurements and plans accordingly which he discussed with us.  He and his helper worked diligently to drill holes and install PVC pipes carefully without splashing or affecting a basement full of yet-unpacked boxes of belongings. They filled cracks and their test holes in the concrete.  We ended up with two vent holes in the basement and one in the garage floor slab each with appropriately-sized pipes integrated into a single exhaust pipe through the roof above the garage.  He placed the venting fan and motor in the attic above the garage so that the sound is undetectable in the house and yard.  The final radon measurements were drastically reduced and well below the acceptable thresholds.  The total price was double what the realtor brashly predicted, but it was a reasonable price for what it took to get the job done <strong>right</strong>.  Based on my experience, I strongly recommend this professional to others for domestic and commercial radon testing and mitigation work. <br />"

FAQs for radon gas testing projects in Casper, WY

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.
