Professional Home Inspectors in Brookfield, WI

Unfortunately, any amount of radon in a home poses a threat to the long-term health of those living in the home. The Environmental Protection Agency recommends radon mitigation in homes with radon levels of 4 picocuries per liter (pCi/L) or greater.

We always test the radon levels in homes after installing mitigation systems. We typically see homes with a pre-mitigation reading of 4 pCi/L coming in at 1 to 2 pCi/L after installing radon mitigation systems.

No. High radon levels affect both old and new homes. However, a 2014 study that looked at radon levels in 273 Sauk County homes found an interesting correlation between newer homes and higher radon levels. Researchers noted that homes built after 2001 had the highest percentage of test results above the EPA recommended action level. One likely explanation is that the newer, more tightly sealed homes produce a stronger suction effect than older, draftier, less well insulated houses. So, while you might think you're better protected against radon in a new home, it could very well be the exact opposite.

Our radon test lasts 48 hours. We set up our equipment in the areas likely to show the highest readings for radon and they record data continuously for the next 48 hours. We then pick up our equipment from your home and analyze the results. In most cases, you will have the results from your radon test the day we pick up our equipment. For a more detailed picture of radon levels, a year-long test is advisable. However, few homeowners have the time or budget for such an extensive test. The accuracy of our equipment in a 48-hour test is more than sufficient to let you know if your home has high levels of radon or not.
