"Best description? Superior work. Thoughtful interaction and patience with the many questions. This was my first experience with work of this nature. Bo, the manager, could not have been more helpful. Alex and Ford worked endlessly to mitigate the mold and at the same time were informative and attentive to my questions. Excellence is the word that describes both their effort and the manner in which they took time to educate me on the remediation. Bo went out of his way to respond to both issues and questions."

"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."

"It went great. They sprayed a pre-spot cleaner and then cleaned my carpets. My old carpets look just like new. I was pleasantly surprised and they exceeded my expectations! Good service, and good quality work."

"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."

"My A/C stopped working at the beginning of a streak of hot weather. I called Seider when they opened at 7:30AM. She took my information and told me they wouldn’t be able to make it until after 5PM as they were fully booked for the day. Also was told after hours rates would apply. At that point I was just happy to know someone would be coming. Especially since it was also the day before a holiday. Not much more than an hour later I got a call from Brandon, a Seider technician. He said he was about 10:minutes away and would it be okay for him to come now. That was more than fine with me. He arrived a short time later. We greeted one another and headed to the backyard where the unit is. He told me he was pretty certain that he knew what the problem was as he was familiar with the model that we have. And, he was right. He removed the failed part. Showed it to me and explained the problem. He retrieved a new one from his truck and installed it. He asked me to turn the air on. I was able to do that with my phone. And, viola! The compressor started right up and continued to run. Before Brandon arrived and replaced the part it would start but then stop after a few seconds. It’s now been about 10 days and the system continues to work like a champ. Thank you Brandon and Seider. It’s getting to be time to replace my furnace and Seider is at the top of the list for that work!"

FAQs for radon gas testing projects in Fredonia, 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.
