What Our Customers Say About Our Radon Services
Adam was wonderful to work with from the very start. Answered all our questions and after he installed the radon system levels are below 1.0!
A-1 lowered our radon levels from over 10.0 pCi/l to below 1.3. Fast and friendly installers. Thanks again for keeping my family safe from radon!
We had very high radon levels. Within two days levels went from 4.8 to 0.4 and still are going down. I was also impressed with the professionalism of A-1 Radon.
These guys are great. Highly recommend! Mitch and David explained everything to me. We found a great place to vent the system through the garage and now the levels are below 1.0.
Service was quick and professional. And best yet, the radon abatement system installed brought my radon levels from 8.9 down to below 0.3 in the basement.
The team listened and were knowledgeable about my concerns. They were efficient and cleaned up after themselves. The radon level, which was above 20, dropped to less than 2.
FAQ About Radon Mitigation Systems
Let our A-1 Radon experts answer any further questions you may have about radon mitigation systems.
Radon tests should be placed in the lowest livable area of your home — typically the basement or first floor if there is no basement. The test should be positioned at least 20 inches above the floor in a location where it won't be disturbed, near open windows, or in high-humidity areas. Avoid placing tests in kitchens, laundry rooms, or bathrooms, as these environments can affect results. A professional radon tester will know the ideal placement to ensure accuracy.
Short-term tests provide a quick snapshot of radon levels over 2–7 days and are great for real estate transactions or initial screening. Long-term tests measure radon concentrations over 90+ days and provide a more representative picture of your home's average radon level. If a short-term test shows elevated levels, a follow-up test or immediate mitigation is recommended. Both testing methods are valuable tools in protecting your family's health.
DIY radon test kits are available at hardware stores and online, and they can provide a reasonable estimate of radon levels. However, professional testing is more accurate, follows strict protocols, and is certified by recognized organizations. A-1 Radon is certified as a Radon Measurement Professional through NRPP and AARST/IEA, ensuring the most reliable results. For peace of mind and actionable data, professional testing is always the recommended choice.
The cost of radon testing varies depending on the method and provider, but it doesn't have to be a barrier to protecting your family. A-1 Radon offers free radon testing to homeowners in the Green Bay, Appleton, Milwaukee, and surrounding Wisconsin areas. This makes it easy and affordable to find out if your home has a radon problem. Don't let cost be a reason to delay — contact A-1 Radon to get started today.
