"I was in the middle of a recent home Refi to get cash out for a new roof and new windows but the credit union wanted a professional report of some interior water damage that was noted during the appraisal process. Donn, from Anderson Home Inspection, was my inspector 20 years ago when I originally purchased my duplex. I contacted Donn and explained the situation and he was very understanding of the need and urgency to get the report for the bank. We scheduled a time 2 days later. Donn quickly assessed the interior water damage and then used his very cool drone to inspect the roof. He took pictures of the roof, interior water stains, and the attic. His report was completed and I submitted it to the credit union. His determination was the interior water stains were cosmetic and not structural. They were due to the poor condition of the valley and chimney flashings and would be corrected this spring when the roof is replaced. Thanks to Anderson Home Inspection my Refi proceeded without further issues and I'm on my way to a new roof and new windows. I have many friends that have used Donn's services and never hesitate to recommend him to anyone."

"Highly recommend Mike, on-time, well-prepared, very thorough, utilized experience, technical expertise and proper tools/analytical devices for very detail oriented inspection. Report was generated and shared within hours of inspection, was well-organized and included pictures, description, recommendations and clearly classified each item as defect or maintenance/monitor. He was also very patient, understanding and offered insightful responses to our many questions and near constant inspection of his inspection. First time home buyer and nosy dad approved. To safeguard Mike's pricing structure I do not provide cost. His value proposition outweighs his cost and I have no reservations paying more than what he charged."

"Scot and Andy were a fantastic team. Patient and thorough, the took the time to answer our questions and gave detailed explanation. They shared things to watch out for and covered all different kinds of maintenance suggestions to help keep our home in good working order. The opening packet of information was a wonderful touch and gave us something to read while we awaited their quick turnaround of the report. We would highly recommend them."

"When I started working real-estate for family and friends in the Eastern part of Wisconsin, a dear friend and referral partner realtor, of mine, recommended Criterion Home Inspectors. I met Scott and was immediately impressed. I had outstanding inspectors back in South Central Wisconsin that had set the bar for HIGH expectations. Scott hit that bar and I've never looked back. Anytime my other inspectors are on vacation, I always give Scott for the opportunity to come over to do the inspection because I know he is going to have integrity, be straightforward, doesn't the report to cover his butt, not an alarmist, and definitely NOT a 'dollar' store inspector. He explains things in layman's terms to the buyers,(and sellers for pre sale inspections) answers all their questions. And if he doesn't know something, he says so and that he will find out, and DOES. Just a great guy and resource for new buyers and seasoned realtors. We highly recommend Scott!!"

FAQs for radon gas testing projects in Sussex, 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.
