What to Do If Your Home Has High Radon Levels

Russell Monges • May 8, 2026

You might have had your home tested for radon for a number of reasons, but it’s always a bit of a shock when the levels come back higher than what is deemed safe (4 pCi/L). Since radon exposure is a risk factor for developing lung cancer and is believed to cause over 20,000 lung cancer deaths per year, it’s essential that you act promptly. What you should not do is panic! High radon levels are common in Connecticut and they can be treated effectively. Here’s what you should do if you find that your home has high levels of radon.


Get Retested

First, if your radon level came back between 4 and 8 pCi/L, you should test again. You can choose a short-term test or a long-term test, which takes several months to complete. Radon levels can fluctuate, and it’s possible that your high test result was a fluke. Test again to be sure. You and your family will not be at any increased risk while the test takes place, whether you choose the long or short test.

Depending on your home, there are several methods that might be used to reduce your radon levels. We might install decompression equipment in a crawl space, put a fan on the exterior of your house, or utilize other methods of reducing radon levels.

There are several factors that go into deciding which method will be most effective, so a home visit is necessary. At Radon Systems of Connecticut, our contractors are trained in EPA's Radon Contractor Proficiency (RCP). This ensures that we are able to determine which method of radon mitigation will work best.

Have Your Radon Mitigation Completed

Once we tell you which type of mitigation is best, we’ll schedule your mitigation for as soon as possible. In addition to installing a device for reducing radon, we’ll show you how your radon levels will be monitored from that point on. Monitoring is important, because if there is ever a problem with your home’s radon levels rising, we need to know about it promptly so it can be fixed.



If you have had a test that indicated high levels of radon, it’s essential to act quickly. Please call us right away so we can walk you through the process of having this harmful gas removed so you can keep your family safe.
