"BEWARE!! Contractor-Dave Nelson talks a big talk but provides UNPROFESSIONAL service and POOR QUALITY work. He will take your money and leave you with a mess of work to redo. BARN ROOF LEAKS in numerous places & is deemed useless. Do not hire this man. The personal trash, numerous cigarette butts, loads of screws, tin pieces all over your property will leave you cleaning up for weeks. We had to replace two tires from the debris left all over. This is not what Senior Citizens need after the stress and tragedy of losing our barn. His website is NOT at all what he states he is. We don’t want anyone to be taken as we have been. Our barn looks like it has been through a hail storm! Every piece of the steel is scratched, dented, painted over and globed up with silicone and then painted over again. Mr. Nelson -contractor posted our barn on his website without our permission. From THAT picture you can tell the aesthetics are of poor quality. (Carriage posts & 2” gaps all around the windows) Feel free to contact us to come look at our barn & his work. Havens wood, Road Roscoe. WE CANNOT RECOMMEND HIM AS A CONTRACTOR."

FAQs for radon gas testing projects in Janesville, 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.
