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."

‘Due Diligence, llc’ is a veteran owned/operated professional home inspection company. While not all home inspectors bring the same level of experience to the table, our sole inspector, with over 25 yrs remodeling and 15 yrs forensic failure analysis, brings more than most. We pride ourselves in providing unbiased, thorough inspections and take the time necessary to insure our clients have a full understanding of any/all concerns identified.

"As a local Realtor, I've worked with many inspectors. But since working with Jeffrey, he is now my #1 go-to Inspector on my speed dial! I can confidently refer him to my Clients, knowing they will be getting the best of the best! While working with Jeffrey, I've been blown away by his attention to detail, how knowledgable he is & how he's able to explain even complex issues in layman's terms - for anyone to understand! His inspection report is the most organized home-owners guide, that I'm confident you will reference the whole time you live in your home! With the level of service you receive... you'll be shocked with how affordable his rates are! There are inspectors out there charging a lot more, and you get a lot less than what Jeffrey will do for you! Hire Jeffrey... you won't be disappointed!"

I always do what i say. Never do I cut corners by using the cheapest fan, or not install something that could put homeowners at risk. I have never quoted a price then asked for more money. I install radon mitigation systems because my family has been affected by cancer. I'm proud of what I do to try and help other families.

"John went out of his way to find an ingenious way of installing a radon mitigation system in our house. He had to drill to the garage from the electric room and connect the pipe there and place a fan on the garage attic, where it took power from the second garage opener. Five years later, the system works fine and we have had no radon. Not only that but he also installed a nice sump pump before sealing the sump well, and this pump has actually saved us a lot of issues this year with the torrential rains we have had (it’s currently running every 5 minutes in November!) John did a fantastic job and for a good price as well. I asked him once to come test the system, and he said it would cost me for him to come over just for that, and he recommended I test it myself, and told me how. All this to save me money. I highly recommend John and I’m sorry I never got to write this review earlier."

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!!"

I hope I only need one remediation system in my lifetime but if I ever had to use his services again, this would be the first spot I would call."

Radon Detection and Reduction questions, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Testing typically costs between $150 and $500, depending on the method used and the number of areas tested.

Radon is a colorless, odorless gas that can cause lung cancer; testing ensures safe indoor air quality.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.
