"We have worked with James twice. He's friendly, professional, and knowledgeable about a variety of engineering concerns. His inspections have been systematic and thorough. On the inspection he did several years ago for us, he identified several items of concern and mechanical systems that were nearing the end of their service life; pretty much everything he predicted would fail soon has, and everything he identified as being totally fine has been in fact totally fine. What more could you ask for?"

"We arrived after the home inspection had been done and he walked us through everything he inspected. With the things that were found wrong with the house, he explained what he would have fixed and why. He was able to recommend several companies that did the type of repairs that were required. When we did quotes, we called a couple others, as well as the ones he mentioned. His came in at the best rate and did a nice job. The hone inspection itself was thorough and he pointed out some things that we missed in our initial viewing of the home."

FAQs for radon gas testing projects in Cashton, WI

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.
