"I spoke with Collin who was extremely helpful, informative, and went above and beyond to give me peace of mind even before moving forward with any work. I made it clear we had many free visual inspections scheduled and had one air test sample done. So rather than charge us and do another air test and inspection, he gave a very thorough second opinion and gave me additional options of over the counter products to use to minimize exposure in the meantime while awaiting results. Speaking with him has really given me more peace of mind and information than the on site inspections we have had so far. When we get all the information needed, I definitely plan to move forward with any repairs and remediation with Collin. He was so above and beyond and thorough before we are even really customers! Really shined!"

"Dustin Anderson, owner of Advanced Drying, came to our house to look for possible mold after HERTSMI testing revealed the presence of a specific type that could be causing health issues for me. Dustin came highly recommended from several people who have similar sensitivities to mold. He was clearly well versed in the subject matter and it was apparent that he is genuinely motivated by helping people with these sensitivities, even if it means his services are not needed. He took the time to answer all of our many questions. Because further testing must be done to determine what remediation would entail, we did not talk about cost. I can't therefore speak to how that might compare to others who offer similar services. What I can tell you is that I was very impressed. I can't imagine finding someone whom I felt more confident in as far as their knowledge and integrity. I am grateful to him for his generosity in time and for the direction he gave in how to proceed. I would absolutely recommend him without hesitation.

FAQs for radon gas testing projects in Casa Grande, AZ

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.
