"I was VERY disappointed by my experience with DJK Environmental. They had come to me as a recommendation from a realtor, so I thought they’d be good. We paid money to have the asbestos test expedited, which took longer than the timeline DJK gave me and they didn’t even call me when the results were in. They also made a few errors on the quote to remove the asbestos, and again didn’t seem to care about the timeline they had given me or earning the business from us. I had to track them down any time I wanted information . They did not keep me informed about anything which was awful considering the timeline we are on to move into our house. When I got quotes from a couple other companies for the same service, I learned that DJK are price gougers as they were going to charge me 40% more than the other bids. I notified my realtor about the horrible communication, awful pricing & negative experience with DJK to ensure they don’t get business from any of her clients ever again. Stay away from DJK"

FAQs for radon gas testing projects in Wisconsin Dells, 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.
