Radon Testing

We guarantee that the Active Mitigation System will bring your home’s Radon level to 3.9 pCi/L (EPA recommended) or below. Many homes will be guaranteed to be 1.9 pCi/L or below at no additional cost. Your Radon level guarantee is in writing, in your contract. We will match the price of any properly certified, insured competitor who offers the same level of service (item for item) with a copy of their written proposal!


Radon Testing for Real Estate Transactions

We test with Continuous Radon Monitors. They measure and print hourly readings, along with an overall average reading. Our 60 monitors are calibrated annually by an EPA/AARST approved lab. They’re also spot checked throughout the year to ensure they haven’t strayed from acceptable accuracy levels.

$75 for Radon test in Appleton, Oshkosh, Fond du Lac,
New London, Waupun, Ripon, Green Bay, and Waupaca.

(We do not conduct tests in the Sheboygan area.)

Radon Testing for Non-Real Estate Transactions

For non real estate transactions, consider conducting the test yourself. Please see How to Radon test your home. By following these directions you’ll get a very accurate reading of your home’s Radon levels.

We offer a Radon Test Program for home owners – and it is completely free if you check out a monitor at our office. Or, if you’re within 30 miles of our Neenah or Menomonee Falls office we can come to your home and set the test up for you at $75. Longer distances will cost more. It’s up to you if you want to conduct the test yourself or have us do it for you. No obligation, no pressure from us to use us to install a system if you do test high. But we hope you would have us do the work.

Testing For Radon in Water

Radon in Water TestRadon gas can escape from private water wells into your drinking and tap water. Regular exposure to breathing the escaped gas or drinking Radon-contaminated water is dangerous, and if you own or use a private water well, you should be proactive and test the water. Public water supplies have many opportunities for Radon gas to naturally escape, and are not a source of concern for exposure.

Get a Radon in water test kit today if you have not tested your private water well. These tests are only $35, and can save precious lives.
