Radon Testing in Wisconsin

Protect your home and your family from dangerous radon gas. Our professional radon testing services provide accurate results, helping buyers, sellers, and real estate agents make informed decisions before a home purchase.

Radon Testing You Can Trust

Radon is a naturally occurring, odorless, and colorless radioactive gas that can seep into homes through foundations and cracks. Wisconsin sits in one of the highest EPA radon zones, and studies show that roughly 50% of homes in our area test above the EPA’s recommended action level. At HomeStart Inspections, we provide thorough, third-party radon testing to give you peace of mind and objective results.

    Very respectful and through. I am not handy so I’m honestly kind of used to people talking down to me when I don’t understand something home-repair wise, but Alan was very patient and answered all my questions as best he could. I also got a nifty manual for being a first time home buyer

    Kyle did a septic inspection for my client's new home.  He was efficient, and thoughtful explaining everything during the inspection.  He handled all questions with quick and great answers.  Kyle and his team at HomeStart will always be my go to inspection company.  The best in the business.

    Matt Luebke did a fantastic job! When he explained the report, he was clear and made sure that we understood everything. As a first time homebuyers we didn’t know what to expect, but Matt made sure to explain everything. He is clearly an experienced professional who truly cares about his job and customers.
