Radon Gone
Radon Gone
Radon Gone strives to provide clients with the greatest value from any National Radon Proficiency Program (NRPP) certified radon testing and mitigation service in Wisconsin while simultaneously creating a greater local awareness for the issue. Radon Gone gives you the personal attention that only a small, local business can provide. We are committed to providing fair and honest services that are performed in a timely manner for an affordable price. If you're still not convinced enough to give us a call or schedule an estimate, let us put you at ease even more with a peace of mind guarantee. Every mitigation service that we provide carries a GUARANTEE that the radon in your home will be reduced to a safe level (under 4 pCi/l or less) or we'll give your money right back to you.
"Radon Gone provided exceptional service from start to finish. They were extremely accommodating, even allowing me to adjust my appointment at the last minute. Ken and his team explained the entire process thoroughly, honored the exact price quoted with no hidden fees, and demonstrated the highest level of professionalism throughout. They worked neatly, kept everything clean, and were genuinely kind and courteous the entire time. Three days later, they returned to collect the commercial radon tester and confirmed that my radon levels were now well below the recommended threshold. After contacting several competitors, it was clear that Radon Gone stood out for their honesty, professionalism, and customer care. I highly recommend them to anyone seeking radon mitigation services."

Anderson Home Inspection LLC
Anderson Home Inspection LLC
PLEASE CALL FOR QUICKEST RESPONSE TIME --Donn Anderson is a Certified Master Inspector®. He began working in construction in the mid 60’s. He started Anderson Home Inspection and performed his first professional home inspection in January of 1995. He has inspected over 12,000 homes in Southeastern Wisconsin since then. He has been a member of the American Society of Home Inspectors – Great Lakes Chapter since 1996. He served as the Education Chairman for the Milwaukee Chapter of the Wisconsin Association of Home Inspectors from 1996 – 2009. He is a member of the National Association of Certified Home Inspectors and is a Certified Master Inspector®. He received his Real Estate license in the mid 1980s. Donn was a co-author of the jurisprudence exam for licensing Wisconsin Home Inspectors. He holds licenses as a WI State UDC Building Inspector, an FHA 203k Consultant, he is certified as a Residential Measurement Provider by NEHA-NRPP to test for Radon, the second leading cause of lung cancer in the US. He works as an expert witness for homeowners who have been exposed to substandard construction and home inspection practices.
"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."

Criterion Home Inspectors LLC
Criterion Home Inspectors LLC
Proudly serving Southeastern Wisconsin, I'm Scott Nelson, I am the owner-operator-inspectors for Criterion Home Inspectors LLC. We take pride in our work & do whatever we can to help home owners insure they maximize the return on their investment. The cost of each job is determined by the square footage of the area to be inspected. Travel charges are not incurred. Visit our website for more testimonials.
"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!!"
