"Time will tell but seemed knowledgeable, they were very informative for us during the inspection and before and their report is well laid out with all that they reviewed including relevant pictures (with arrows, circles on important parts)."

"I was interested in having a home inspection done to identify any areas that we should focus on for maintenance this year and to minimize any surprises when we eventually think about selling our home. Mike was very personable and took the time to make sure he understood my objectives and goals and explained everything that he would be doing during the inspection. He kept me informed throughout the inspection and reviewed his findings verbally while he was onsite, and I had the finished report that evening. All very professional and thorough. Would hire again. I also appreciated that during the initial call to setup the appointment Mike said that he would wear a mask while in our home and asked that we do the same before I asked the same. I've found most people are happy to comply when they are here to do work, but I appreciate that Mike was proactive about our safety and his."

"Sansara did a fantastic job in restoring our lower level bathroom and family room after a frozen/busted water pipe flooded the area. Jamie and his crew were on the scene shortly after the water mitigation work was completed by Sansara’s mitigation team. The rebuild process was quick and the carpentry work was professional. The damaged areas were restored beautifully and looks like nothing ever happened. I highly recommend Sansara if you ever need mitigation and rebuild or, just want to remodel."

FAQs for radon gas testing projects in Valley Park, 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.
